Measuring and valuing health benefits for economic evaluation in adolescence: an assessment of the practicality and validity of the child health utility 9D in the Australian adolescent population

Determining the Content Validity of the EQ-5D-5L, EQ-5D-Y-3L, and CHU9D Instruments for Assessing Generic Child and Adolescent Health-Related Quality of Life: A Qualitative Study

BACKGROUND

Health technology assessment agencies typically recommend generic measures of health to generate quality-adjusted life-years. Most agencies provide recommendations on which measure to use for adults, whereas few make recommendations for children. Two widely used preference-weighted measures of child and adolescent health that have evidence of good psychometric performance are the EQ-5D-Y-3L and the Child Health Utility 9D Index (CHU9D). The EQ-5D-5L has also been used to assess adolescent health. However, evidence on their content validity-a core measurement property-is limited. The objective of this study was to explore the content validity of the EQ-5D-5L, EQ-5D-Y-3L, and CHU9D measures, including their relevance, comprehensiveness, and comprehensibility.

METHODS

We assessed the content validity of the EQ-5D-5L, EQ-5D-Y-3L, and CHU9D using online semi-structured cognitive interviews in the UK. Participants were asked to comment on the relevance, comprehensibility, and comprehensiveness of the measures, including response options, recall period, and completion instructions. Interviews were informed by a topic guide. Purposive sampling allowed for appropriate breadth in the sample, with variation in gender, and presence of health conditions, disease, or disability. Interviews were recorded and transcribed verbatim before thematic content analysis.

RESULTS

In total, we conducted 49 interviews between August 2022 and June 2023: 21 children/adolescents aged 8-17 years and 28 parents/guardians of children aged 4-17 years. The mean duration of the interviews was 45 min. Relevance was broadly supported, but issues were identified. Comprehensibility was inconsistent on some items, and participants expressed difficulty with grouped items (e.g., 'anxiety/depression'). Participants had difficulty distinguishing qualitatively between some response options (e.g., 'a little bit/a bit'). Some participants noted that instrument comprehensiveness was insufficient.

CONCLUSIONS

Although the content of the EQ-5D-5L, EQ-5D-Y-3L, and CHU9D was broadly supported, potential problems were identified in aspects of comprehensibility, relevance, and comprehensiveness. These present opportunities for future research and refinement to ultimately improve the content validity of these measures for assessing child and adolescent health.

Cost Analysis of Recurrent Emergency Department Visits Among Patients Aged 65 and Older: A Retrospective Cross-Sectional Study

Introduction This study aimed to analyze the costs of emergency department (ED) visits among patients aged 65 years and older, with a particular focus on the financial burden of recurrent admissions within a one-year period. Methods A retrospective cross-sectional study was conducted on 143,909 ED visits recorded between January 1, 2014, and December 31, 2014, at the Emergency Department of Ankara Atatürk Training and Research Hospital, Ankara, Turkey. Data for patients aged 65 and older were extracted from the Hospital Information Management System. Cost data were based on the Social Security Institution billing system and converted into US dollars (USD) using the 2014 exchange rate. Patients were categorized by age, gender, diagnosis, and visit frequency. Nonparametric statistical tests were used due to the non-normal distribution of cost variables. A p-value < 0.05 was considered statistically significant. Results A total of 21,458 (15.0%) ED visits were made by patients aged 65 and older. The median cost per visit in this group was $58.16. Costs increased with age: $42.90 for patients aged 65-74, $76.67 for those aged 75-84, and $96.42 for those aged ≥85 (Kruskal-Wallis H = 1,125.3, df = 2, p < 0.001). Among the 19,159 elderly patients who visited the ED, 1,951 (10.2%) had recurrent visits. Within this subgroup, internal medicine diagnoses were most common (1,345 visits, or 68.9%), followed by pulmonary (320, or 16.4%), cardiovascular (211, or 10.8%), and non-specific complaints (231, or 11.8%) as the leading causes. This diagnostic distribution differed significantly from that of single-visit patients (χ² = 42.7, df = 3, p < 0.001). Recurrence rates varied significantly by diagnostic category (χ² = 89.4, df = 5, p < 0.001): the highest recurrence was observed in patients with hematologic conditions (56/355, or 15.8%; adjusted OR = 1.72, 95% CI: 1.28-2.31), followed by psychiatric (8/57, or 14.0%; adjusted OR = 1.45, 95% CI: 0.99-2.12) and pulmonary diagnoses (320/2,358, or 13.6%; adjusted OR = 1.38, 95% CI: 1.22-1.57), all above the overall recurrence rate of 10.2%. The median cost of the first ED visit was significantly higher in the recurrent group ($72.13) compared to the non-recurrent group ($59.76) (Mann-Whitney U = 14.2 × 10⁶, p < 0.001, r = 0.14). Among recurrent cases, the mean cost of the first visit ($101.84) exceeded the average cost of subsequent visits ($93.98) (Wilcoxon T = 2.4 × 10⁵, p < 0.001, r = 0.09). Conclusion Older patients generate disproportionately higher ED costs in Turkey, particularly those with recurrent visits and chronic conditions. These findings support the implementation of geriatric-focused emergency care models and preventive strategies to optimize resource utilization in aging populations.

Practicality, Validity, and Responsiveness of Using the Proxy Version of the Child Health Utility-9 Dimensions With Children Aged 2 to 5 Years

OBJECTIVES

This study aimed to assess the practicality, validity, and responsiveness of the proxy Child Health Utility-9 Dimensions (CHU9D) in children aged 2 to 5 years.

METHODS

We used data from the Barrier Enhancement for Eczema Prevention trial, a UK randomized controlled trial testing whether daily emollients in infancy could prevent eczema in high-risk infants. The main parent/carer completed the proxy CHU9D using developers' additional guidance for completion in those younger than 5 years and the Patient-Oriented Eczema Measure (POEM) at ages 2, 3, 4, and 5 years. Practicality was assessed by completion rates. Construct validity assessed whether CHU9D could discriminate between those with/without eczema and between eczema severity levels on POEM. Responsiveness was determined by ability to discriminate between 3 groups: (1) those whose POEM score deteriorated ≥3 points, (2) those whose change was not clinically important (-2.9 to 2.9 points), and (3) those whose POEM score improved ≥3 points. Analysis was conducted in Stata 17.

RESULTS

Of 1394 children participating in the Barrier Enhancement for Eczema Prevention trial, study questionnaires were completed by 1212 (87%), 981 (70%), 990 (71%), and 976 (70%) at 2, 3, 4, and 5 years. Of these the CHU9D was completed by 1066 (88.0%), 685 (69.8%), 925 (93.4%), and 923 (94.6%), respectively. Mean utility at all time points was approximately 0.934 (range 0.443-1). For construct validity, very small differences in the CHU9D between known groups were observed (P < .01). A total of 801 participants had responsiveness data: 13% deteriorated, 72% had nonclinically important change, and 15% improved. Mean utility change (standardized response mean) for these groups was -0.0198 (0.21), 0.0041 (0.05), and 0.0175 (0.21) showing small change and small responsiveness.

CONCLUSIONS

Proxy CHU9D in 2- to 5-year-old children shows potential but further research is needed.

Emotional literacy programme in special schools for children with a learning disability in England: the ZF-SEND feasibility RCT

Background

Children with a learning disability experience a range of inequalities and adverse life events that put them at greater risk of mental health problems. The construct of emotional literacy has been shown to be a moderating factor of how life stress affects mental health. Teaching emotional literacy in schools may therefore be an effective way to promote positive mental health. There is an identified need for adapted emotional literacy programmes in special schools.

Objectives

To evaluate whether it is feasible to conduct a large-scale randomised controlled trial of the effectiveness and cost-effectiveness of an emotional literacy programme (Zippy's Friends special educational needs and disabilities) for children with a learning disability in special schools. The key aims were to assess the acceptability and feasibility of participating in the trial, data collection and the Zippy's Friends special educational needs and disabilities intervention through quantitative and qualitative data collection.

Design

A feasibility, cluster randomised controlled trial that aimed to recruit and randomise 12 special schools to either deliver the intervention over 1 academic year or continue with practice as usual and to collect data from 96 pupils at baseline (pre randomisation) and 12 months post randomisation.

Setting

Special schools in England and Scotland.

Participants

Pupils with a learning disability, aged 9-11 years, attending special schools in England. Follow-up interviews were conducted with 8 pupils, 4 parents/carers and 11 school staff members.

Intervention

Zippy's Friends for Special Educational Needs and Disabilities is a manual-based, classroom-based emotional literacy programme focused on a problem-solving approach to develop and improve children's emotional literacy. The mainstream programme has been adapted for children with a learning disability by simplifying the activities, shortening the sessions and introducing more repetition.

Main outcome measures

Feasibility and acceptability of: (1) participation in the research trial; (2) the collection of the outcome measure data and (3) the Zippy's Friends for Special Educational Needs and Disabilities intervention.

Results

A total of 8 schools and 53 pupils were recruited. Retention of schools after randomisation (100%) and retention of pupils (100%) met the prespecified progression criteria. For recruitment of schools (20.5% of those approached), pupil engagement with the intervention (50%) and collection of outcome and service use data (62.3%) the criteria were partially met. Fidelity of the intervention delivery (48%) fell just below the progression criteria. Thus, the feasibility and acceptability outcome progression criteria were largely met, suggesting that progression to a full trial is warranted with amendments to the study design.

Limitations

This feasibility trial was conducted during the COVID-19 pandemic, resulting in unusually high absences of pupils and teachers, different classroom arrangements (bubbles) and unprecedented stress and emotional challenges for pupils, parents and teaching staff. The findings are therefore specific to that period and all three main outcomes of this feasibility trial were adversely affected.

Conclusions

The findings of this study indicate that a large-scale randomised controlled trial is feasible provided that a number of amendments to the study design are made to improve: (1) the timing of the project to suit the demands of special schools' yearly timetable; (2) recruitment and (3) outcome and service use data collection.

Future work

On the basis of the current findings, an application for a full trial will be prepared and submitted with a number of amendments.

Interpersonal counselling for adolescent depression delivered by youth mental health workers without core professional training: the ICALM feasibility RCT

Background

As milder cases of adolescent depression do not meet treatment thresholds for specialist mental health services, young people often receive support from non-qualified professionals in third-sector/voluntary agencies. Early psychological interventions to meet growing demand with limited resources are crucial.

Objectives

The study aimed to explore the effectiveness and cost effectiveness of interpersonal counselling for adolescents by (1) assessing the feasibility and acceptability of trial procedures; (2) exploring the delivery of, and differences between, interpersonal counselling for adolescents and treatment as usual; (3) evaluating the extent of contamination of the control arm and if it should be mitigated against in a future trial; and (4) investigating whether the interval estimate of benefit of interpersonal counselling for adolescents over treatment as usual in depression post treatment includes a clinically significant effect.

Design

This was a feasibility randomised controlled trial. Non-qualified professionals from non-specialist mental health services received interpersonal counselling for adolescent training. Participants were randomised to receive either interpersonal counselling for adolescents plus treatment as usual or treatment as usual only. Assessments occurred at baseline and were followed up at weeks 5, 10 and 23. A health economics component was included to inform the design of the economic evaluation in a future study. A process evaluation examined implementation of the intervention across settings, acceptability and contamination. Interviews, observations and focus groups were analysed using thematic analysis. Session recordings were analysed using conversation analysis.

Setting

The trial was conducted in 13 non-speicialist mental health services across Norfolk and Suffolk.

Participants

Help-seeking adolescents aged 12-18 years with mild depression as the primary difficulty were eligible to participate. Comorbid presentations were not an exclusion criterion. Of a target of 60, 16 participants were randomised, and 2 participants withdrew following study suspensions related to COVID-19. Of the remaining 14 participants, 7 received an intervention, with 3 receiving interpersonal counselling for adolescents and 4 receiving treatment as usual. The rest either disengaged, withdrew or were signposted.

Interventions

Participants were randomised to receive either interpersonal counselling for adolescents plus treatment as usual or treatment as usual only.

Main outcome measures

The primary outcome was the Revised Children's Anxiety and Depression Scale, although the proposed study was not designed to assess efficacy. The primary output of the feasibility trial was to design a subsequent full-scale trial.

Results

Feasibility outcomes did not meet the estimated progression criteria. Despite efforts to increase referrals, the 80% recruitment rate was not achieved. Interpersonal counselling for adolescents' attendance rates at 10 weeks were less than the 70% progression criteria estimation, impacting intervention feasibility. Retention was high, with 85.7% of participants reaching 23-week follow-up. The health economic measures appeared to perform well and were completed. Implementation and theoretical fidelity of interpersonal counselling for adolescents were analysed from four participant recordings. Adherence to the principles of interpersonal counselling for adolescents was identified, with 100% satisfactory fidelity and no indication of contamination in the control arm. The two interventions were clinically non-significant due to the study being underpowered.

Limitations

The feasibility of the randomised controlled trial was impacted by COVID-19. Services had to change standard practices, disrupting trial procedures. Challenges were identified when implementing a randomised controlled trial in non-specialist services.

Conclusions

Findings indicate a randomised controlled trial of interpersonal counselling for adolescents in non-specialist services is not feasible, yet the data collection and outcome measures were suitable. COVID-19 challenges, sites' lack of familiarity with research procedures and the research team's unfamiliarity with how different early intervention services operate led to challenges. High staff shortages, turnover and inconsistent training could have been considered. This study demonstrated the difficulties in conducting a randomised controlled trial in this service setting. Further work is needed to improve the feasibility of conducting such trials before they are attempted in future.

EQ-5D-5L Population Scores in Mainland China: Results From a Nationally Representative Survey 2021

OBJECTIVES

There is a lack of monitoring changes in the population scores of the most recent version, EQ-5D-5L, in mainland China. This study aimed to address this knowledge gap by assessing the EQ-5D-5L scores in mainland China using a nationally representative sample.

METHODS

Data were extracted from the 2021 Survey of Health Index of Chinese Families, which covered 31 provinces/autonomous regions/municipalities in mainland China. The survey used a multistage quota sampling strategy encompassing 120 prefecture-level cities. Quotas were allocated to each prefecture-level city in accordance with the 2020 China Population Census. This approach resulted in a final sample of 11 030 eligible questionnaires. The utility index (UI) and EuroQol Visual Analog Scale (EQ VAS) scores were reported for the entire sample (age-gender-urban/rural weighted) and by the characteristics of the study participants.

RESULTS

The study participants had a weighted mean UI of 0.939 (SD 0.135) and EQ VAS score of 80.19 (SD 18.39). The most commonly reported problem was anxiety/depression (26.37%), whereas self-care was the least reported problem (6.18%). Those who were male, were younger, lived without chronic conditions and disabilities, had higher levels of education, earned higher monthly household income, and were covered by basic medical insurance for urban employees had higher scores in both the UI and EQ VAS.

CONCLUSION

This study revealed slightly lower UI scores despite a much higher drop in EQ VAS scores whereas China maintained minimum cases of COVID-19 in 2021 compared with the population norms recorded in 2019. Further studies are warranted to unveil the full impacts of COVID-19 outbreaks.

Study protocol for the Multimodal Approach to Preventing Suicide in Schools (MAPSS) project: A regionally based feasibility trial of an integrated response to suicide risk among UK secondary school pupils

BACKGROUND

Suicide is the leading cause of death of children and young people under 35 in the UK, and suicide rates are rising in this age group. Schools are considered an appropriate and logical setting for youth suicide prevention activities, with universal, selective, and indicated approaches all demonstrating efficacy. Given that international best practice recommends suicide prevention programmes combine these approaches, and that to date this has not been done in school settings in the UK, this study aims to evaluate the feasibility of delivering a suicide prevention programme incorporating universal, selective, and indicated components in UK schools.

METHODS

This study is a feasibility cluster-randomised controlled trial (RCT) of an adapted version of the Multimodal Approach to Preventing Suicide in Schools (MAPSS) programme. The programme, initially developed in Australia, involves delivering universal psychoeducation to all pupils, screening them for suicide risk, and delivering Internet-based Cognitive Behavioural Therapy (Reframe IT-UK) to those students identified as being at high-risk for suicide. The programme will be trialled in six secondary schools in Northwest England and will target Year 10 students (14- and 15-year-olds). The primary aims are to assess: 1) the acceptability and safety of delivering MAPSS in a school setting in the UK; 2) the social validity of the MAPSS programme; and 3) the feasibility of delivering a large-scale, appropriately powered, cluster-RCT and economic evaluation of this intervention in the future. Secondary aims are to assess changes over time in mental health and wellbeing outcomes.

DISCUSSION

This study is the first to evaluate a suicide prevention programme comprising universal, selective, and indicated components in UK schools. If the programme is found to be feasible, it could be more widely tested in schools and may ultimately lead to reduced rates of suicide and suicidal behaviour in young people.

Psychometric Properties of Child Health Utility 9D (CHU9D) Proxy Version Administered to Parents and Caregivers of Children Aged 2-4 Years Compared with Pediatric Quality of Life Inventory™ (PedsQL)

OBJECTIVE

This study examines the psychometric properties of the Child Health Utility 9D (CHU9D) proxy version administered to parents/caregivers of 2-4-year-old Australian children compared with Pediatric Quality of Life Inventory™ version 4.0 (PedsQL).

METHODS

Data collected in 2021/2022 from parents/caregivers of 2-4-year-olds from the Australian pediatric multi-instrument comparison study were used. Feasibility, ceiling/floor effects, test-retest reliability, convergent validity, known-group validity, and responsiveness were assessed.

RESULTS

A total of 842 caregivers completed the survey at baseline, with 513 completing the follow-up survey. The CHU9D did not demonstrate ceiling effects in the sample with special health care needs, with only 6% of respondents reporting best levels for all nine dimensions. CHU9D correlated with PedsQL moderately-to-strongly between comparable items (correlation coefficients 0.34-0.70). CHU9D was able to differentiate between groups with known health differences with moderate-to-large effect sizes (Cohen's d 0.58-2.03). Moderate test-retest reliability was found for CHU9D in those reporting no health change at a 2-day follow-up (ICC 0.52). A standard response mean (SRM) of 0.25-0.44 was found for children with changes in general health and a SRM of 0.72-0.82 for children who reported worsened health when developing new illnesses, indicating small-to-large responsiveness according to different definitions of health changes. Compared with PedsQL, CHU9D had similar known-group validity and responsiveness and slightly poorer test-retest reliability.

CONCLUSION

The CHU9D was found to be valid and reliable to measure health-related quality-of-life in children aged 2-4 years, although with relatively low test-retest reliability in some dimensions. Further development and validation work is warranted.

It's time for change: inequities and determinants of health-related quality of life among gender and sexually diverse young people in Australia

PURPOSE

This study was guided by three research aims: firstly, to examine the longitudinal trends of health-related quality of life (HR-QoL) among gender and sexuality diverse (LGBTQA2S+) young people through adolescence (ages 14-19); secondly, to assess longitudinal associations between poor mental health and HR-QoL among LGBTQA2S+ young people through adolescence; and thirdly, to examine differences in HR-QoL among LGBTQA2S+ young people during early adolescence (ages 14 and 15) depending on select school-, peer-, and parent-level factors.

METHODS

This study used three of nine available waves of data from a large population-level, probability sample-based, longitudinal cohort study, namely the K' cohort: children aged 4-5 years old at time of study enrolment followed-up biennially (~ 61% retention rate). HR-QoL weighted means and standard deviations were calculated using Child Health Utility 9D (CHU-9D) scores for LGBTQA2S+ participants at ages 14 and 15 (Wave 6), ages 16 and 17 (Wave 7), and ages 18 and 19 (Wave 8). To strategically identify policy-relevant modifiable behavioural factors suitable for prevention and early intervention, non-parametric Wilcoxon signed-rank tests tested differences in mean CHU-9D ranks at ages 14 and 15 (Wave 6) between groups (gender identity: trans vs. cis; identity-level sexuality: gay, lesbian, bisexual, or other diverse sexuality vs. heterosexual; group-level sexuality: sexually diverse vs. not sexually diverse) and selected school factors (school acceptance, belonging, freedom of expression), peer factors (peer relationship quality, trust, respect), and family factors (parental acceptance, understanding, trust), with Hedge's g correction statistics computed for effect sizes. Longitudinal associations between gender, sexuality, and poor mental health (depressive symptoms, anxiety, symptoms, self-harm thoughts/behaviour, and suicidal thoughts/behaviour) and HR-QoL were tested using mixed-effects models with random intercepts and random slopes for nested clustering (participants within postcodes).

RESULTS

HR-QoL disparities disproportionately affecting LGBTQA2S+ groups relative to their cisgender, heterosexual peers, were well-established by age 14 to 15 relatively steeper reductions in HR-QoL were observed throughout adolescence among all LGBTQA2S+ groups, with HR-QoL widening the most for trans participants. Poor mental health was significantly associated with HR-QoL declines. LGBTQA2S+ participants with positive school- and parent factors related to feelings of acceptance, belonging, and freedom of self-expression, reported significantly higher HR-QoL during early adolescence.

CONCLUSION

Evidence-based public health policy responses are required to address the dire HR-QoL inequities among LGBTQA2S+ young people, particularly trans young people. Prioritising the promotion of school- and family-based interventions which foster LGBTQA2S+ inclusivity, acceptance, and a sense of belonging from early adolescence through young adulthood, represents a feasible, evidence-based, and cost-effective response to address these HR-QoL disparities.

Comparing Generic Paediatric Health-Related Quality-of-Life Instruments: A Dimensionality Assessment Using Factor Analysis

BACKGROUND

Widely used generic instruments to measure paediatric health-related quality of life (HRQoL) include the EQ-5D-Y-5L, Child Health Utility 9 Dimension (CHU-9D), Paediatric Quality of Life Inventory (PedsQL) and Health Utilities Index (HUI). There are similarities and differences in the content of these instruments, but there is little empirical evidence on how the items they contain relate to each other, and to an overarching model of HRQoL derived from their content.

OBJECTIVE

This study aimed to explore the dimensionality of the instruments using exploratory factor analysis (EFA).

METHODS

Data from the Australian Paediatric Multi-Instrument Comparison (P-MIC) Study were used. EQ-5D-Y-5L, CHU-9D, PedsQL and HUI data were collected via proxy or child self-report data. EFA was used to investigate the underlying domain structure and measurement relationship. Items from the four instruments were pooled and domain models were identified for self- and proxy-reported data. The number of factors was determined based on eigenvalues greater than 1. A correlation cut-off of 0.32 was used to determine item loading on a given factor, with cross-loading also considered. Oblique rotation was used.

RESULTS

Results suggest a six-factor structure for the proxy-reported data, including emotional functioning, pain, daily activities, physical functioning, school functioning, and senses, while the self-report data revealed a similar seven-factor structure, with social functioning emerging as an additional factor.

CONCLUSION

We provide evidence of differences and similarities between paediatric HRQoL instruments and the aspects of health being measured by these instruments. The results identified slight differences between self- and proxy-reported data in the relationships among items within the resulting domains.

Comparing the Psychometric Performance of Generic Paediatric Health-Related Quality of Life Instruments in Children and Adolescents with ADHD, Anxiety and/or Depression

OBJECTIVE

The aim of this study was to examine the validity, reliability and responsiveness of common generic paediatric health-related quality of life (HRQoL) instruments in children and adolescents with mental health challenges.

METHODS

Participants were a subset of the Australian Paediatric Multi-Instrument Comparison (P-MIC) study and comprised 1013 children aged 4-18 years with attention-deficit/hyperactivity disorder (ADHD) (n = 533), or anxiety and/or depression (n = 480). Participants completed an online survey including a range of generic paediatric HRQoL instruments (PedsQL, EQ-5D-Y-3L, EQ-5D-Y-5L, CHU9D) and mental health symptom measures (SDQ, SWAN, RCADS-25). A subset of participants also completed the HUI3 and AQoL-6D. The psychometric performance of each HRQoL instrument was assessed regarding acceptability/feasibility; floor/ceiling effects; convergent validity; known-group validity; responsiveness and test-retest reliability.

RESULTS

The PedsQL, CHU9D, EQ-5D-Y-3L and EQ-5D-Y-5L showed similarly good performance for acceptability/feasibility, known-group validity and convergent validity. The CHU9D and PedsQL showed no floor or ceiling effects and fair-good test-retest reliability. Test-retest reliability was lower for the EQ-5D-Y-3L and EQ-5D-Y-5L. The EQ-5D-Y-3L showed the highest ceiling effects, but was the top performing instrument alongside the CHU9D on responsiveness to improvements in health status, followed by the PedsQL. The AQoL-6D and HUI3 showed good acceptability/feasibility, no floor or ceiling effects, and good convergent validity, yet poorer performance on known-group validity. Responsiveness and test-retest reliability were not able to be assessed for these two instruments. In subgroup analyses, performance was similar for all instruments for acceptability/feasibility, known-group and convergent validity, however, relative strengths and weaknesses for each instrument were noted for ceiling effects, responsiveness and test-retest reliability. In sensitivity analyses using utility scores, performance regarding known-group and convergent validity worsened slightly for the EQ-5D-Y-3L and CHU9D, though improved slightly for the HUI3 and AQoL-6D.

CONCLUSIONS

While each instrument showed strong performance in some areas, careful consideration of the choice of instrument is advised, as this may differ dependent on the intended use of the instrument, and the age, gender and type of mental health condition of the population in which the instrument is being used.

The Social and Emotional Education and Development intervention to address wellbeing in primary school age children: the SEED cluster RCT

Background

Stronger social and emotional well-being during primary school is positively associated with the health and educational outcomes of young people. However, there is little evidence on which programmes are the most effective for improving social and emotional well-being.

Objective

The objective was to rigorously evaluate the Social and Emotional Education and Development (SEED) intervention process for improving pupils' social and emotional well-being.

Design

This was a stratified cluster randomised controlled trial with embedded process and economic evaluations. Thirty-eight primary schools were randomly assigned to the SEED intervention or to the control group. Hierarchical regression analysis allowing for clustering at school learning community level was conducted in R (statistical package).

Setting

The SEED intervention is a whole-school intervention; it involved all school staff and two cohorts of pupils, one starting at 4 or 5 years of age and the second starting at 8 or 9 years of age, across all 38 schools.

Participants

A total of 2639 pupils in Scotland.

Intervention

The SEED intervention used an iterative process that involved three components to facilitate selection and implementation of school-based actions: (1) questionnaire completion, (2) benchmarked feedback to all staff and (3) reflective discussions (all staff and an educational psychologist).

Main outcome measure

The primary outcome was pupils' Strengths and Difficulties Questionnaire-Total Difficulties Score when pupils were 4 years older than at baseline.

Results

The primary outcome, pupils' Strengths and Difficulties Questionnaire-Total Difficulties Score at follow-up 3, showed improvements for intervention arm pupils, compared with those in the control arm [relative risk -1.30 (95% confidence interval -1.87 to -0.73), standardised effect size -0.27 (95% confidence interval -0.39 to -0.15)]. There was no evidence of intervention effects according to deprivation: the results were significant for both affluent and deprived pupils. Subgroup analysis showed that all effect sizes were larger for the older cohort, particularly boys [relative risk -2.36 (95% confidence interval -3.62 to -1.11), standardised effect size -0.42 (95% confidence interval -0.64 to -0.20)]. Although there was no statistically significant difference in incremental cost and quality-adjusted life-years, the probability that the intervention is cost-effective at a willingness-to-pay threshold of £20,000 per quality-adjusted life-year was high, at 88%. Particularly valued mechanisms of the SEED intervention were its provision of time to reflect on and discuss social and emotional well-being and its contribution to a culture of evaluating practice.

Limitations

It was a challenge to retain schools over five waves of data collection.

Conclusions

This trial demonstrated that the SEED intervention is an acceptable, cost-effective way to modestly improve pupil well-being and improve school climate, particularly for older boys and those with greater levels of psychological difficulties. It was beneficial during the transition from primary to secondary school, but this diminished after 6 years. The SEED intervention can be implemented alongside existing systems for addressing pupil well-being and can be complementary to other interventions.

Future work

Assess whether or not the SEED intervention has a beneficial impact on academic attainment, is transferable to other countries and other organisational settings, would be strengthened by adding core training elements to the intervention process and is transferable to secondary schools. Understand the gender differences illustrated by the outcomes of this trial. Conduct further statistical research on how to handle missing data in longitudinal studies of complex social interventions.

Health-related quality of life and subjective well-being among children aged 9-12 years in Shandong Province, China

PURPOSE

To investigate the health-related quality of life (HRQoL) and subjective well-being (SWB) of children aged 9-12 years in eastern China, and examine concordance within child self-reported and parent proxy-assessed.

METHODS

Data was collected from 9 to 12 years old children (including their parents) in Shandong Province in 2018. Participants self-completed a hard-copy questionnaire including Child Health Utility 9D (CHU9D), Pediatric Quality of Life Inventory (PedsQL)™ 4.0 Short Form 15 Generic Core Scales (hereafter the PedsQL™), Student's Life Satisfaction Scale (SLSS), as well as information on socio-demographic characteristics and self-report health status. Spearman's correlation coefficients and the difference between sub-groups were conducted to assess and compare the agreement on HRQoL and SWB instruments. Exploratory factor analysis (EFA) was used to ascertain the number of unique underlying latent factors that were associated with the items covered by the two generic HRQoL and the SWB instruments. The concordance of child self-reported and parent proxy-assessed was analyzed using weighted kappa coefficient and Bland-Altman plots.

RESULTS

A total of 810 children and 810 parents were invited to participate in the survey. A valid sample of 799 (98.6%) children and 643 (79.4%) parents completed the questionnaire. The child self-reported mean scores were CHU9D = 0.87, PedsQL™ = 83.47, and SLSS = 30.90, respectively. The parent proxy-assessed mean scores were PedsQL™ = 68.61 and SLSS = 31.23, respectively. The child self-reported PedsQL™ was moderately correlated with the CHU9D (r = 0.52). There was a weak correlation between CHU9D and SLSS (r = 0.27). The EFA result found 3 factors whilst seven SLSS items grouped into a standalone factor (factor 3), and the nine dimensions of CHU9D shared two common factors with the PedsQL™ (factor 1 and factor 2). A low level of concordance was observed across all comparisons and in all domains (weighted kappa < 0.20) between parents and their children. Furthermore, a high level of discordance was observed between child self-reported and father proxy-assessed.

CONCLUSIONS

CHU9D and PedsQL™ instruments have a higher agreement in measuring the HRQoL in children. CHU9D/PedsQL™ and SLSS instruments showed a low agreement and EFA result suggested that measuring SWB in children potentially may provide further information, which might be overlooked by using HRQoL instruments exclusively. Concordance of child self-reported and parent proxy-assessed was poor. Overall, mother-child concordance was higher than father-child concordance.

A psychometric investigation of health-related quality of life measures for paediatric neurodevelopment assessment: Reliability and concurrent validity of the PEDS-QL, CHU-9D, and the EQ-5D-Y

There is a need for tools that can provide a brief assessment of functioning for children with neurodevelopmental conditions, including health-related quality of life (HR-QoL). This study evaluated the psychometric properties of three commonly used and well known HR-QoL measures in a cohort of children presenting to clinical developmental assessment services. The most common diagnoses received in these assessment services were autism spectrum disorders. Findings showed good internal consistency for the PedsQL and the CHU-9D, but not the EQ-5D-Y. This research also found that the CHU-9D, EQ-5D-Y, and PedsQL correlated with relevant functioning domains assessed by the VABS-III. Overall, the measures showed that children with neurodevelopmental conditions experienced poor HR-QoL. The majority of children (>86%) met cut-off criteria for significant health concerns on the PedsQL. On the EQ-5D-Y and CHU-9D, they showed reduced HR-QoL particularly on domains relating to school and homework, being able to join in activities, looking after self, and doing usual activities. This study supports the use of the CHU-9D and PedsQL in this population to assess and potentially track HR-QoL in a broad neurodevelopment paediatric population.

Co-design of a paediatric post-trauma electronic psychosocial screen

PURPOSE

To optimise care pathways and provide greater transparency of the psychosocial needs of injured children after hospital discharge by extending post-discharge psychosocial screening to children admitted with traumatic injury for ≥24 h.

DESIGN AND METHODS

This mixed-methods study used a co-design approach informed by the Experience-Based Co-design (EBCD) framework. Interviews with carers were used to evaluate experiences and generate views on psychosocial support interventions. Online surveys by international child psychologists' indicated preferences for a psychosocial screening tool, and clinician-stakeholder consensus meetings facilitated the development of an electronic post-injury psychosocial screening tool.

RESULTS

Carers found the initial year of follow-up from trauma family support services helpful, appreciating the hospital connection. Flexible follow-up timings and additional resources were mentioned, and most carers were interested in participating in an electronic screening activity to predict their child's coping after injury. Child trauma experts recommended including several screening tools, and the multidisciplinary paediatric trauma service and study investigators collaborated over a year to workshop and reach a consensus on the screening tool and follow-up process.

CONCLUSION

The multidisciplinary team co-designed an electronic psychosocial screening and follow-up process for families with children with traumatic injuries. This tool improves the visibility of injured children's psychosocial needs post-injury and potentially aids clinical targeted resource allocation for trauma family support services.

PRACTICE IMPLICATIONS

The study emphasises the significance of specialised psychosocial screening tools in paediatric nursing, especially in trauma care, for understanding patients' psychosocial needs, tailoring follow-up plans, and promoting a patient-centred approach.

Effectiveness of a Regenerative Epithelial Suspension (RES), on the pigmentation of split-thickness skin graft donor sites in children: the dRESsing pilot randomised controlled trial protocol

BACKGROUND

Paediatric donor site wounds are often complicated by dyspigmentation following a split-thickness skin graft. These easily identifiable scars can potentially never return to normal pigmentation. A Regenerative Epidermal Suspension (RES) has been shown to improve pigmentation in patients with vitiligo, and in adult patients following a burn injury. Very little is known regarding the efficacy of RES for the management of donor site scars in children.

METHODS AND ANALYSIS

A pilot randomised controlled trial of 40 children allocated to two groups (RES or no RES) standard dressing applied to donor site wounds will be conducted. All children aged 16 years or younger requiring a split thickness skin graft will be screened for eligibility. The primary outcome is donor site scar pigmentation 12 months after skin grafting. Secondary outcomes include re-epithelialisation time, pain, itch, dressing application ease, treatment satisfaction, scar thickness and health-related quality of life. Commencing 7 days after the skin graft, the dressing will be changed every 3-5 days until the donor site is ≥ 95% re-epithelialised. Data will be collected at each dressing change and 3, 6 and 12 months post skin graft.

ETHICS AND DISSEMINATION

Ethics approval was confirmed on 11 February 2019 by the study site Human Research Ethics Committee (HREC) (HREC/18/QCHQ/45807). Study findings will be published in peer-reviewed journals and presented at national and international conferences. This study was prospectively registered on the Australian New Zealand Clinical Trials Registry (available at https://anzctr.org.au/ACTRN12620000227998.aspx).

Examining the impact of a universal social and emotional learning intervention (Passport) on internalising symptoms and other outcomes among children, compared to the usual school curriculum: study protocol for a school-based cluster randomised trial

BACKGROUND

School-based universal social and emotional learning (SEL) interventions implemented during the transition to adolescence may be efficacious in preventing the development of mental health difficulties. This protocol describes a two-arm parallel cluster randomised controlled trial to investigate the impact of a universal SEL intervention (Passport, compared to usual provision) on internalising symptoms (primary outcome), emotion regulation, well-being, loneliness, social support, bullying, academic attainment, and health-related quality of life in English primary school pupils aged 9-11 years. A developer-led trial demonstrated the feasibility, acceptability, and utility of Passport; this will be the first independent trial.

METHODS

Sixty primary schools will be recruited across the Greater Manchester city region and surrounding areas, involving 2400 pupils aged 8-9 at baseline. Schools will be allocated to the intervention arm to implement Passport over 18 weekly sessions or to the control arm to implement the usual school curriculum. Random allocation will be at school level following completion of baseline measures, with minimisation to ensure balance across trial arms in school size and free school meal eligibility. Measures will be collected at baseline, post-intervention (12 months post-baseline), and at 12 months follow-up (24 months post-baseline). The primary outcome analysis (intervention effects on internalising symptoms at post-intervention) will comprise a two-level (school, child) hierarchical linear model, following the intention-to-treat principle. Additional analyses will be undertaken to assess intervention effects on secondary outcomes, maintenance effects for all outcomes, intervention compliance moderator effects, subgroup moderator effects, and mechanisms underpinning intervention effects on the primary outcome. A mixed-methods implementation and process evaluation will examine factors that influence implementation, and a health economic evaluation will assess the cost-effectiveness of the intervention.

DISCUSSION

Findings will provide educators with crucial knowledge of whether and how increasing emotion regulation through a universal intervention impacts internalising symptoms and a range of related outcomes. Findings will also inform policy related to the promotion of mental health among children and young people. If the intervention is found to be efficacious in reducing internalising symptoms and is also cost-effective, it may offer high potential as a preventative intervention for widespread implementation.

Child-Parent Agreement in the Assessment of Health-Related Quality of Life Using the CHU9D and the PedsQLTM

OBJECTIVE

This study examined the inter-rater agreement between child-self and parental proxy health-related quality of life (HRQoL) ratings (overall and domain level) using two different generic child-specific measures, the Child Health Utility 9D (CHU9D) and the Pediatric Quality of Life Inventory (PedsQLTM), in a community-based sample of Australian children. A secondary objective was to investigate the impact of age on child-parent agreement across the dimensions of the two measures.

METHODS

A total of 85 child-parent dyads (children aged 6-12 years) recruited from the community completed the self and proxy versions of the CHU9D and the PedsQLTM, respectively. The inter-rater agreement was estimated using Concordance Correlation Coefficients (CCC) and Gwet's Agreement Coefficient (AC1) for the overall sample and across age-groups.

RESULTS

Agreement was low for overall HRQoL for both the CHU9D (CCC = 0.28) and the PedsQLTM (CCC = 0.39). Across the CHU9D dimensions, agreement was the highest for 'sad' (AC1 = 0.83) and lowest for 'tired' (AC1 = 0.31). The PedsQLTM demonstrated stronger agreement (AC1 = 0.41-0.6) for the physical health dimension but weaker for the psychosocial dimensions (AC1 < 0.4). Except for the 'tired' dimension, agreement was consistent across age-groups with the CHU9D, whilst the PedsQLTM showed poor agreement for most of the psychosocial health items among the older age-groups only (8-10 and 11-12 years).

CONCLUSION

This study highlights that the agreement between child and parent proxy reported HRQoL may be influenced by both the measure used and the age of the child. These findings may have implications for the economic evaluation of healthcare interventions and services in child populations when both child and proxy perspectives are considered in the assessment of child HRQoL.

Psychometric Evaluation of the PedsQL GCS and CHU9D in Australian Children and Adolescents with Common Chronic Health Conditions

BACKGROUND

Generic instruments such as the Pediatric Quality of Life Inventory™ v4.0 Generic Core Scales (PedsQL GCS) and Child Health Utility 9D (CHU9D) are widely used to assess health-related quality of life (HRQOL) of the general childhood population, but there is a paucity of information about their psychometric properties in children with specific health conditions. This study assessed psychometric properties, including acceptability, reliability, validity, and responsiveness, of the PedsQL GCS and the CHU9D in children and adolescents with a range of common chronic health problems.

METHODS

We used data from the Longitudinal Study of Australian Children (LSAC), for children aged 10-17 years with at least one of the following six parent-reported health conditions: asthma, anxiety/depression, attention deficit hyperactivity disorder (ADHD), autism/Asperger's, epilepsy, and type 1 diabetes mellitus. The LSAC used parent proxy-reported PedsQL GCS and child self-reported CHU9D assessments. The performance of each instrument (PedsQL GCS and CHU9D) for each psychometric property (acceptability, reliability, validity, and responsiveness) was assessed against established criteria.

RESULTS

The study sample included 7201 children and adolescents (mean age = 14 years; range 10.1-17.9 years; 49% female) with 15,568 longitudinal observations available for analyses. Across the six health conditions, acceptability of the PedsQL GCS was high, while acceptability for the CHU9D was mixed. Both the PedsQL GCS and CHU9D showed strong internal consistency (Cronbach's alpha range: PedsQL GCS = 0.70-0.95, CHU9D = 0.76-0.84; item-total correlations range: PedsQL GCS = 0.35-0.84, CHU9D = 0.32-0.70). However, convergent validity for both the PedsQL GCS and CHU9D was generally weak (Spearman's correlations ≤ 0.3). Known group validity was strong for the PedsQL GCS (HRQOL differences were detected for children with and without asthma, anxiety/depression, ADHD, autism/Asperger's, and epilepsy). CHU9D was only able to discriminate between children with and without anxiety/depression, ADHD, and autism/Asperger's. The responsiveness of both the PedsQL GCS and CHU9D was variable across the six conditions, and most of the estimated effect sizes were relatively small (< 0.5).

CONCLUSION

This study expands the evidence base of psychometric performance of the PedsQL GCS and CHU9D and can aid in appropriate HRQOL instrument selection for the required context by researchers and clinicians.

Assessing micro- vs macro-costing approaches for treating appendicitis in children with appendicectomy or non-operatively

OBJECTIVES

We conducted a health economic sub-study within a feasibility RCT comparing a non-operative treatment pathway as an alternative to appendicectomy for the treatment of uncomplicated acute appendicitis in children. The objectives were to understand and assess data collection tools and methods and to determine indicative costs and benefits assessing the feasibility of conducting a full economic evaluation within the definitive trial.

METHODS

We compared different methods of estimating treatment costs including micro-costing, hospital administrative data (PLICS) and health system (NHS) reference costs. We compared two different HRQoL instruments (CHU-9D and EQ-5D-5L) in terms of data completeness and sensitivity to change over time, including potential ceiling effects. We also explored how the timing of data collection and duration of the analysis could affect QALYs (Quality Adjusted Life Years) and the results of the cost-utility analysis (CUA) within the future RCT.

RESULTS

Using a micro-costing approach, the total per treatment costs were in alignment with hospital administrative data (PLICS). Average health system reference cost data (macro-costing using NHS costs) could potentially underestimate these treatment costs, particularly for non-operative treatment. Costs incurred following hospital discharge in the primary care setting were minimal, and limited family borne costs were reported by parents/carers. While both HRQoL instruments performed relatively well, our results highlight the problem of ceiling effect and the importance of the timing of data collection and the duration of the analysis in any future assessment using QALYs and CUA.

CONCLUSIONS

We highlighted the importance of obtaining accurate individual-patient cost data when conducting economic evaluations. Our results suggest that timing of data collection and duration of the assessment are important considerations when evaluating cost-effectiveness and reporting cost per QALY.

Utility for Uncorrected Refractive Errors in Adolescent Schoolchildren in Kakamega County, Kenya

SIGNIFICANCE

Uncorrected refractive errors (UREs) present an enormous lifetime burden in children. Despite this, there is a dearth of knowledge on URE-related preference-based quality of life (QoL) in East Africa. This study demonstrates the positive impact of interventions on UREs; hence, it provides an empirical justification for advocacy to improve the QoL of children with URE.

PURPOSE

This study investigated the preference-based QoL (utility) for URE in school-going adolescents of Kakamega County, in Kenya.

METHODS

An observational cross-sectional study with multistage sampling was conducted on randomly selected secondary school adolescents. School-going adolescents in Forms 1 to 4 were clinically examined for the presence of URE and classified according to their URE types. Pre-screened students who met the selection criteria were classified into two groups: URE and normal sight. Participants in the normal-sight group were randomly selected from among screened students without URE. Selected participants were administered a previously validated adolescent-specific utility weighting instrument-Assessment of Quality of Life-Six Dimensions.

RESULTS

A total of 330 participants aged 17.32 ± 1.60 years (URE, 17.50 ± 1.58 years; normal-sight, 17.15 ± 1.61 years) were included in the study. The mean utility score, as elicited by the Assessment of Quality of Life-Six Dimensions scoring algorithm, was better in the normal-sight group (URE, 0.496 ± 0.22; normal sight, 0.567 ± 0.25) at baseline, whereas the reverse was true at follow-up (URE, 0.655 ± 0.20; normal sight, 0.603 ± 0.25). In all cases, the differences were significant ( P < .05); however, there was no significantly better ( P > .05) utility elicited by any URE subtype at any given time point. Nonetheless, the URE group showed significantly better utility ( P < .05) after spectacle correction.

CONCLUSIONS

Uncorrected refractive errors are associated with reduced utility in school-going adolescents, regardless of URE subtype. Spectacle correction resulted in a significantly improved utility for those with URE. Thus, this study recommends early public health strategies and spectacle interventions in schools for adolescents with URE.

Systematic Review of the Psychometric Performance of Generic Childhood Multi-attribute Utility Instruments

BACKGROUND

Childhood multi-attribute utility instruments (MAUIs) can be used to measure health utilities in children (aged ≤ 18 years) for economic evaluation. Systematic review methods can generate a psychometric evidence base that informs their selection for application. Previous reviews focused on limited sets of MAUIs and psychometric properties, and only on evidence from studies that directly aimed to conduct psychometric assessments.

OBJECTIVE

This study aimed to conduct a systematic review of psychometric evidence for generic childhood MAUIs and to meet three objectives: (1) create a comprehensive catalogue of evaluated psychometric evidence; (2) identify psychometric evidence gaps; and (3) summarise the psychometric assessment methods and performance by property.

METHODS

A review protocol was registered with the Prospective Register of Systematic Reviews (PROSPERO; CRD42021295959); reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guideline. The searches covered seven academic databases, and included studies that provided psychometric evidence for one or more of the following generic childhood MAUIs designed to be accompanied by a preference-based value set (any language version): 16D, 17D, AHUM, AQoL-6D, CH-6D, CHSCS-PS, CHU9D, EQ-5D-Y-3L, EQ-5D-Y-5L, HUI2, HUI3, IQI, QWB, and TANDI; used data derived from general and/or clinical childhood populations and from children and/or proxy respondents; and were published in English. The review included 'direct studies' that aimed to assess psychometric properties and 'indirect studies' that generated psychometric evidence without this explicit aim. Eighteen properties were evaluated using a four-part criteria rating developed from established standards in the literature. Data syntheses identified psychometric evidence gaps and summarised the psychometric assessment methods/results by property.

RESULTS

Overall, 372 studies were included, generating a catalogue of 2153 criteria rating outputs across 14 instruments covering all properties except predictive validity. The number of outputs varied markedly by instrument and property, ranging from 1 for IQI to 623 for HUI3, and from zero for predictive validity to 500 for known-group validity. The more recently developed instruments targeting preschool children (CHSCS-PS, IQI, TANDI) have greater evidence gaps (lack of any evidence) than longer established instruments such as EQ-5D-Y, HUI2/3, and CHU9D. The gaps were prominent for reliability (test-retest, inter-proxy-rater, inter-modal, internal consistency) and proxy-child agreement. The inclusion of indirect studies (n = 209 studies; n = 900 outputs) increased the number of properties with at least one output of acceptable performance. Common methodological issues in psychometric assessment were identified, e.g., lack of reference measures to help interpret associations and changes. No instrument consistently outperformed others across all properties.

CONCLUSION

This review provides comprehensive evidence on the psychometric performance of generic childhood MAUIs. It assists analysts involved in cost-effectiveness-based evaluation to select instruments based on the application-specific minimum standards of scientific rigour. The identified evidence gaps and methodological issues also motivate and inform future psychometric studies and their methods, particularly those assessing reliability, proxy-child agreement, and MAUIs targeting preschool children.

Reliability, acceptability, validity and responsiveness of the CHU9D and PedsQL in the measurement of quality of life in children and adolescents with overweight and obesity

BACKGROUND

The Paediatric Quality of life Inventory (PedsQL^TM) Generic Core Scales and the Child Health Utilities 9 Dimensions (CHU9D) are two paediatric health-related quality of life (HRQoL) measures commonly used in overweight and obesity research. However, no studies have comprehensively established the psychometric properties of these instruments in the context of paediatric overweight and obesity. The aim of this study was to assess the reliability, acceptability, validity and responsiveness of the PedsQL and the CHU9D in the measurement of HRQoL among children and adolescents living with overweight and obesity.

SUBJECTS/METHODS

Subjects were 6544 child participants of the Longitudinal Study of Australian Children, with up to 3 repeated measures of PedsQL and CHU9D and aged between 10 and 17 years. Weight and height were measured objectively by trained operators, and weight status determined using World Health Organisation growth standards. We examined reliability, acceptability, known group and convergent validity and responsiveness, using recognised methods.

RESULTS

Both PedsQL and CHU9D demonstrated good internal consistency reliability, and high acceptability. Neither instrument showed strong convergent validity, but PedsQL appears to be superior to the CHU9D in known groups validity and responsiveness. Compared with healthy weight, mean (95%CI) differences in PedsQL scores for children with obesity were: boys -5.6 (-6.2, -4.4); girls -6.7 (-8.1, -5.4) and differences in CHU9D utility were: boys -0.02 (-0.034, -0.006); girls -0.035 (-0.054, -0.015). Differences in scores for overweight compared with healthy weight were: PedsQL boys -2.2 (-3.0, -1.4) and girls -1.3 (-2.0, -0.6) and CHU9D boys: no significant difference; girls -0.014 (-0.026, -0.003).

CONCLUSION

PedsQL and CHU9D overall demonstrated good psychometric properties, supporting their use in measuring HRQoL in paediatric overweight and obesity. CHU9D had poorer responsiveness and did not discriminate between overweight and healthy weight in boys, which may limit its use in economic evaluation.

Study protocol of the Our Futures Vaping Trial: a cluster randomised controlled trial of a school-based eHealth intervention to prevent e-cigarette use among adolescents

BACKGROUND

Effective and scalable prevention approaches are urgently needed to address the rapidly increasing rates of e-cigarette use among adolescents. School-based eHealth interventions can be an efficient, effective, and economical approach, yet there are none targeting e-cigarettes within Australia. This paper describes the protocol of the OurFutures Vaping Trial which aims to evaluate the efficacy and cost-effectiveness of the first school-based eHealth intervention targeting e-cigarettes in Australia.

METHODS

A two-arm cluster randomised controlled trial will be conducted among Year 7 and 8 students (aged 12-14 years) in 42 secondary schools across New South Wales, Western Australia and Queensland, Australia. Using stratified block randomisation, schools will be assigned to either the OurFutures Vaping Program intervention group or an active control group (health education as usual). The intervention consists of four web-based cartoon lessons and accompanying activities delivered during health education over a four-week period. Whilst primarily focused on e-cigarette use, the program simultaneously addresses tobacco cigarette use. Students will complete online self-report surveys at baseline, post-intervention, 6-, 12-, 24-, and 36-months after baseline. The primary outcome is the uptake of e-cigarette use at 12-month follow-up. Secondary outcomes include the uptake of tobacco smoking, frequency/quantity of e-cigarettes use and tobacco smoking, intentions to use e-cigarettes/tobacco cigarettes, knowledge about e-cigarettes/tobacco cigarettes, motives and attitudes relating to e-cigarettes, self-efficacy to resist peer pressure and refuse e-cigarettes, mental health, quality of life, and resource utilisation. Generalized mixed effects regression will investigate whether receiving the intervention reduces the likelihood of primary and secondary outcomes. Cost-effectiveness and the effect on primary and secondary outcomes will also be examined over the longer-term.

DISCUSSION

If effective, the intervention will be readily accessible to schools via the OurFutures platform and has the potential to make substantial health and economic impact. Without such intervention, young Australians will be the first generation to use nicotine at higher rates than previous generations, thereby undoing decades of effective tobacco control.

The trial has been prospectively registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12623000022662; date registered: 10/01/2023).

A comparison of the Child Health Utility 9D and the Health Utilities Index for estimating health utilities in pediatric inflammatory bowel disease

PURPOSE

Health utilities are challenging to ascertain in children and have not been studied in pediatric Crohn's disease (CD) and ulcerative colitis (UC). The objective was to assess discriminative validity by comparing utilities elicited using the Child Health Utility-9 Dimension (CHU9D) to the Health Utilities Index (HUI) across multiple disease activity scales in pediatric UC and CD.

METHODS

Preference-based instruments were administered to 188 children with CD and 83 children with UC aged 6 to 18 years. Utilities were calculated using CHU9D adult and youth tariffs, and HUI2 and HUI3 algorithms in children with inactive (quiescent) and active (mild, moderate, and severe) disease. Differences between instruments, tariff sets and disease activity categories and were tested statistically.

RESULTS

In CD and UC, all instruments detected significantly higher utilities for inactive compared to active disease (p < 0.05). Mean utilities for quiescent disease ranged from 0.810 (SD 0.169) to 0.916 (SD 0.121) in CD and from 0.766 (SD 0.208) to 0.871 (SD 0.186) in UC across instruments. Active disease mean utilities ranged from 0.694 (SD 0.212) to 0.837 (SD 0.168) in CD and from 0.654 (SD 0.226) to 0.800 (SD 0.128) in UC.

CONCLUSION

CHU9D and HUI discriminated between levels of disease activity in CD and UC regardless of the clinical scale used, with the CHU9D youth tariff most often displaying the lowest utilities for worse health states. Distinct utilities for different IBD disease activity states can be used in health state transition models evaluating the cost-effectiveness of treatments for pediatric CD and UC.

Health-related quality of life for children using orthokeratology (OK), peripheral lenslet designed (PLD) and single-vision (SV) spectacles: based on Child Health Utility 9 Dimensions (CHU9D)

PURPOSE

This study investigated the health-related quality of life (HRQoL) among children with myopia who used orthokeratology (OK), peripheral lenslet designed (PLD), and single-vision (SV) spectacles.

METHODS

This cross-sectional study was conducted between February of 2021 and August of 2022. It involved 211, 231, and 206 respondents with OK, PLD, and SV spectacle lenses, respectively. The HRQoL was presented as utility values using a general preference-based Child Health Utility-nine Dimensions (CHU9D) questionnaire. Descriptive statistical analysis and nonparametric hypothesis testing were used to compare the HRQoL in the OK, PLD, and SV groups.

RESULTS

Of the 648 respondents, the average utility scores was 0.936 (95 % confidence interval (CI): 0.929-0.943). Children who wore the PLD spectacles had a significantly higher utility scores (0.955, 95 % CI: 0.946-0.963) than those who wore the SV spectacles (0.926, 95 % CI: 0.913-0.939) and the OK lenses (0.925, 95 % CI: 0.913-0.937) (p < 0.01). The PLD spectacle wearers were less likely to be worried, sad, tired, or annoyed than those who wore OK and SV spectacles (P < 0.05). Self-reported improved eyesight and lessened eye pain and discomfort from myopia correction using PLD spectacles had higher utility values (P < 0.05).

CONCLUSIONS

The PLD spectacles had a significantly higher HRQoL than the OK and SV spectacles among children. Having better eyesight and less eye pain/discomfort from myopia correction could improve the HRQoL of children. This data indicates that PLD spectacles may be considered for myopia management in children and adolescents.

A Pilot Randomised Controlled Trial Evaluating a Regenerative Epithelial Suspension for Medium-Size Partial-Thickness Burns in Children: The BRACS Trial

BACKGROUND

There is little evidence regarding the efficacy of Regenerative Epidermal Suspension (RES™) management for paediatric partial-thickness burns. The Biobrane® RECELL® Autologous skin Cell suspension and Silver dressings (BRACS) Trial evaluated three dressings for the re-epithelialisation of partial-thickness burns in children.

METHODS

Eligible children (age ≤ 16 years; ≥5% TBSA; ≤48 h of injury) were randomised to silver dressings, RES™/Biobrane® or Biobrane®. The measured outcomes were the time to re-epithelialisation (primary outcome), pain, itch, intervention fidelity, treatment satisfaction, health-related quality of life, health resource utilisation and adverse effects.

RESULTS

The median time to re-epithelialisation in days was no different for RES™/Biobrane® at 12 (IQR: 5.6-18.4; n = 7) and slower by two days for Biobrane® at 14 (IQR: 6.3-21.7; n = 7) when compared to silver dressings 12 (IQR: 3.7-20.3; n = 8). Reduced pain, fewer infections, no sepsis, no skin graft, and the lowest impact on health-related quality of life were reported in the RES™/Biobrane® group compared to other groups. Due to the COVID-19 pandemic, recruitment suspension resulted in a smaller cohort than expected and an underpowered study.

CONCLUSIONS

The pilot trial findings should be interpreted cautiously; however, they indicate that a fully powered randomised controlled trial is warranted to substantiate the role of RES™ for medium to large paediatric partial-thickness burn management.

Mapping PedsQL™ scores to CHU9D utility weights for children with chronic conditions in a multi-ethnic and deprived metropolitan population

PURPOSE

The Child Health Utility-9 Dimensions (CHU9D) is a patient-reported outcome measure to generate Quality-Adjusted Life Years (QALYs), recommended for economic evaluations of interventions to inform funding decisions. When the CHU9D is not available, mapping algorithms offer an opportunity to convert other paediatric instruments, such as the Paediatric Quality of Life Inventory™ (PedsQL), onto the CHU9D scores. This study aims to validate current PedsQL to CHU9D mappings in a sample of children and young people of a wide age range (0 to 16 years of age) and with chronic conditions. New algorithms with improved predictive accuracy are also developed.

METHODS

Data from the Children and Young People's Health Partnership (CYPHP) were used (N = 1735). Four regression models were estimated: ordinal least squared, generalized linear model, beta-binomial and censored least absolute deviations. Standard goodness of fit measures were used for validation and to assess new algorithms.

RESULTS

While previous algorithms perform well, performance can be enhanced. OLS was the best estimation method for the final equations at the total, dimension and item PedsQL scores levels. The CYPHP mapping algorithms include age as an important predictor and more non-linear terms compared with previous work.

CONCLUSION

The new CYPHP mappings are particularly relevant for samples with children and young people with chronic conditions living in deprived and urban settings. Further validation in an external sample is required. Trial registration number NCT03461848; pre-results.

Psychometric Properties of Generic Preference-Weighted Measures for Children and Adolescents: A Systematic Review

INTRODUCTION

Preference-weighted measures (PWMs)-also referred to as preference-based measures in the literature-of health status/health-related quality of life plays an essential role in estimating quality-adjusted life-years (QALY) for use in economic evaluations of healthcare products and interventions. However, as PWMs are first and foremost intended to accurately reflect respondent health status, they should ideally demonstrate good psychometric properties for the population in question. This study aimed to systematically review published evidence on the measurement properties of commonly used PWMs for children and adolescents.

METHODS

Three electronic databases (PubMed, Medline, and PsycINFO) were searched for articles assessing the psychometric properties (content validity, construct validity-including convergent validity and known-group validity, test-retest reliability, and responsiveness) of the PWMs of interest (AQoL-6D, CHU9D, HUI2, HUI3, and EQ-5D-Y). The COsensus-based Standards for the selection of health Measurement INstruments methodology (COSMIN) guidelines were used to assess (a) the methodological quality of the studies included and (b) the psychometric performance of the instruments covered. Data were analysed overall as well as by population (country and disease group) and perspective (self-report or proxy-report). The study protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42021277296).

RESULTS

In total, 53 articles were included in this systematic review. Health Utilities Index (HUI) was tested only in patient populations, CHU9D was most frequently tested in general population samples, while EQ-5D-Y was tested in both populations. Overall, there was high-quality evidence supporting sufficient construct validity for all instruments except AQoL-6D. Evidence supporting test-retest and responsiveness was scarce. There was high-quality evidence supporting sufficient responsiveness of HUI2 and HUI3, and inconsistent test-retest reliability of CHU9D and EQ-5D-Y. Evidence for content validity was minimal and therefore not extracted and synthesized for any PWMs.

CONCLUSION

This review provides updated evidence on the measurement properties of existing generic PWMs for children and adolescents. High-quality evidence for all relevant psychometric properties and across a range of populations was not available for any of the instruments included, indicating that further work is needed in this direction. This study has identified some of the most noticeable evidence gaps for each of the individual measures. Users can use this information to guide their decision on the choice of PWM to administer.

Assessment of Quality of Life of Transgender and Gender-Diverse Children and Adolescents in Melbourne, Australia, 2017-2020

IMPORTANCE

Transgender and gender-diverse (TGD) children and adolescents may experience not only gender dysphoria but also depression and anxiety, all of which are likely to be associated with reduced quality of life (QOL). Despite this, little is known about QOL in this population.

OBJECTIVES

To identify demographic, social, and clinical characteristics associated with reduced QOL in TGD children and adolescents; compare their QOL with age-matched population-based norms and that of young people with common mental health problems; and evaluate the association between gender dysphoria and QOL.

DESIGN, SETTING, AND PARTICIPANTS

In this cohort study, baseline data were derived from questionnaires completed in a prospective cohort study (Trans20) of TGD children aged 6 to 12 years and adolescents aged 13 to 17 years first seen at the Royal Children's Hospital Gender Service (Melbourne, Australia) between February 2017 and February 2020.

MAIN OUTCOMES AND MEASURES

The main outcome was QOL, measured using the Child Health Utility 9D instrument (CHU-9D). Data collection included demographic information, social factors (eg, bullying, lack of support, and social transition), and clinical characteristics (eg, gender identity, gender dysphoria, and mental health difficulties). Population norms and CHU-9D data for Australian youths with mental health diagnoses were derived from published literature.

RESULTS

The TGD cohort comprised 525 children and adolescents aged 6 to 17 years (median age, 14 years [IQR, 12-16 years]; 364 [69.33%] presumed female at birth). The mean (SD) CHU-9D score was 0.46 (0.26). Compared with population norms, TGD children (0.58 [0.27] vs 0.81 [0.16]; P < .001) and adolescents (0.41 [0.25] vs 0.80 [0.14]; P < .001) had significantly lower scores. Within the TGD cohort, mean (SD) scores were significantly lower in adolescents (0.41 [0.24] vs 0.62 [0.25]; P < .001), those assigned female at birth (0.43 [0.26] vs 0.55 [0.25]; P < .001), those reporting mental health problems (0.37 [0.23] vs 0.57 [0.25]; P < .001) and physical health problems (0.41 [0.26] vs 0.48 [0.26]; P = .04), and those who were bullied (0.38 [0.24] vs 0.52 [0.25]; P < .001). Gender dysphoria alone was associated with a lower mean (SD) CHU-9D score (0.51 [0.23]) than that in control adolescents with serious mental health conditions such as depression (0.64 [0.26]) and anxiety (0.70 [0.24]) and was an independent factor associated with QOL.

CONCLUSIONS AND RELEVANCE

In this cohort study of TGD children and adolescents in Australia, QOL was worse in this population than in age-matched, population-based peers. Quality of life associated with gender dysphoria was substantially worse than that seen in young people with common mental health conditions. These findings emphasize the risk of poor QOL among TGD young people and the need to better support them.

One session treatment (OST) is equivalent to multi-session cognitive behavioral therapy (CBT) in children with specific phobias (ASPECT): results from a national non-inferiority randomized controlled trial

BACKGROUND

5%-10% children and young people (CYP) experience specific phobias that impact daily functioning. Cognitive Behaviour Therapy (CBT) is recommended but has limitations. One Session Treatment (OST), a briefer alternative incorporating CBT principles, has demonstrated efficacy. The Alleviating Specific Phobias Experienced by Children Trial (ASPECT) investigated the non-inferiority of OST compared to multi-session CBT for treating specific phobias in CYP.

METHODS

ASPECT was a pragmatic, multi-center, non-inferiority randomized controlled trial in 26 CAMHS sites, three voluntary agency services, and one university-based CYP well-being service. CYP aged 7-16 years with specific phobia were randomized to receive OST or CBT. Clinical non-inferiority and a nested cost-effectiveness evaluation was assessed 6-months post-randomization using the Behavioural Avoidance Task (BAT). Secondary outcome measures included the Anxiety Disorder Interview Schedule, Child Anxiety Impact Scale, Revised Children's Anxiety Depression Scale, goal-based outcome measure, and EQ-5DY and CHU-9D, collected blind at baseline and six-months.

RESULTS

268 CYPs were randomized to OST (n = 134) or CBT (n = 134). Mean BAT scores at 6 months were similar across groups in both intention-to-treat (ITT) and per-protocol (PP) populations (CBT: 7.1 (ITT, n = 76), 7.4 (PP, n = 57), OST: 7.4 (ITT, n = 73), 7.6 (PP, n = 56), on the standardized scale-adjusted mean difference for CBT compared to OST -0.123, 95% CI -0.449 to 0.202 (ITT), mean difference -0.204, 95% CI -0.579 to 0.171 (PP)). These findings were wholly below the standardized non-inferiority limit of 0.4, suggesting that OST is non-inferior to CBT. No between-group differences were found on secondary outcomes. OST marginally decreased mean service use costs and maintained similar mean Quality Adjusted Life Years compared to CBT.

CONCLUSIONS

One Session Treatment has similar clinical effectiveness to CBT for specific phobias in CYP and may be a cost-saving alternative.

Progressive resistance training in young people with Prader-Willi syndrome: protocol for a randomised trial (PRESTO)

INTRODUCTION

Preliminary evidence suggests that progressive resistance training may be beneficial for people with Prader-Willi Syndrome (PWS), a rare genetic condition that results in muscle weakness and low muscle tone.To establish whether community-based progressive resistance training is effective in improving the muscle strength of people with PWS; to determine cost-effectiveness; and, to complete a process evaluation assessing intervention fidelity, exploring mechanisms of impact, understanding participant experiences and identifying contextual factors affecting implementation.

METHODS AND ANALYSIS

A multisite, randomised controlled trial will be completed. Sixty participants with PWS will be randomised to receive either progressive resistance training (experimental) or non-progressive exercise (placebo control). Participants will be aged 13 to 60 years, be able to follow simple instructions in English and have no contraindications to performing progressive resistance training. The experimental group will complete progressive resistance training two times weekly for 24 weeks supervised by an exercise professional at a community gym. The control group will receive all aspects of the intervention except progressive overload. Outcomes will be assessed at week 25 (primary endpoint) and week 52 by a blinded assessor. The primary outcome is muscle strength assessed using one repetition maximum for upper limb and lower limb. Secondary outcomes are muscle mass, functional strength, physical activity, community participation, health-related quality of life and behaviour. Health economic analysis will evaluate cost-effectiveness. Process evaluation will assess safety and intervention fidelity, investigate mechanism of impact, explore participant experiences and identify contextual factors affecting implementation. Data collection commenced in February 2020 and will conclude in September 2023.

ETHICS AND DISSEMINATION

Ethical approval was obtained from The Royal Children's Hospital Human Research Ethics Committee (HREC/50874/RCHM-2019) under the National Mutual Acceptance initiative. Research governance approvals were obtained from five clinical sites. Results will be disseminated through published manuscripts, conference presentations, public seminars and practical resources for stakeholder groups.

Investigating the psychometric properties of the EQ-5D-Y-3L, EQ-5D-Y-5L, CHU-9D, and PedsQL in children and adolescents with osteogenesis imperfecta

The objective of this study was to evaluate and compare the psychometric properties of the EQ-5D-Y-3L, EQ-5D-Y-5L, CHU-9D, and PedsQL, in a sample of children and adolescents with osteogenesis imperfecta (OI). A web-based cross-sectional survey was conducted among Chinese children and adolescents with OI in 2021. The EQ-5D-Y-3L, EQ-5D-Y-5L, CHU-9D, and PedsQL were used to assess the health-related quality of life for the participants. Construct validity, including convergent and divergent validity, known-group validity, and test-retest reliability, was examined to assess the psychometric properties of the measures. A total of 157 pediatric OI patients self-completed the questionnaire. Few of them reported the full health status. A strong ceiling effect was observed for all dimensions on the EQ-5D-Y and most on CHU-9D. Most dimensions of the EQ-5D-Y and CHU-9D showed statistically significant correlations with the hypothesized PedsQL subscales. The test-retest reliability for the EQ-5D-Y-3L, EQ-5D-Y-5L, and CHU-9D was acceptable. The EQ-5D-Y-5L showed a better known-group validity than EQ-5D-Y-3L, CHU-9D, and PedsQL in differentiating patients in risk groups.

CONCLUSION

The results confirmed that the EQ-5D-Y and CHU-9D are reliable and valid in pediatric OI patients. The EQ-5D-Y-5L performed better than EQ-5D-Y-3L regarding acceptability, convergent validity, and discriminatory power.

WHAT IS KNOWN

• Performance of the preference-based measures has never been reported in patients with Osteogenesis imperfecta.

WHAT IS NEW

• The EQ-5D-Y demonstrated higher sensitivity and discriminatory power than the CHU-9D in patients with osteogenesis Imperfecta • The EQ-5D-Y-3L performed slightly better than EQ-5D-Y-5L regarding convergent validity and discriminant ability.

Protocol for a randomised controlled trial evaluating the effectiveness of a CBT-based smartphone application for improving mental health outcomes in adolescents: the MobiliseMe study

BACKGROUND

Depression is a leading cause of disability in adolescents, however few receive evidence-based treatment. Despite having the potential to overcome barriers to treatment uptake and adherence, there are very few CBT-based smartphone apps for adolescents. To address this gap, we developed ClearlyMe®, a self-guided CBT smartphone app for adolescent depression and anxiety. ClearlyMe® consists of 37 brief lessons containing core CBT elements, accessed either individually or as part of a 'collection'. Here, we describe the protocol for a randomised controlled trial aiming to evaluate the effect of ClearlyMe® on depressive symptoms and secondary outcomes, including engagement, anxiety and wellbeing, when delivered with and without guided support compared to an attention matched control.

METHODS

We aim to recruit 489 adolescents aged 12-17 years with mild to moderately-severe depressive symptoms. Participants will be screened for inclusion, complete the baseline assessment and are then randomly allocated to receive ClearlyMe® (self-directed use), ClearlyMe® with guided SMS support (guided use) or digital psychoeducation (attention-matched control). Depressive symptoms and secondary outcomes will be assessed at 6-weeks (primary endpoint) and 4-months post-baseline (secondary endpoint). Engagement, conceptualised as uptake, adherence and completion, will also be assessed 6-weeks post-baseline. Mixed-effects linear modelling will be used to conduct intention-to-treat analyses to determine whether reductions in depressive symptoms and secondary outcomes are greater for conditions receiving ClearlyMe® relative to control at 6-weeks and 4-months post-baseline and greater for intervention adherers relative to non-adherers. To minimise risk, participants will be encouraged to use the Get Help section of the app and can also opt to receive a call from the team clinical psychologist at baseline, and at the 6-week and 4-month post-baseline assessments when reporting suicidal ideation.

DISCUSSION

This is the first clinical trial examining a CBT smartphone app specifically designed for adolescent depression. It will provide empirical evidence on the effects of ClearlyMe® on depressive symptoms when used with and without guided support.

Cost-effectiveness of scar management post-burn: a trial-based economic evaluation of three intervention models

Optimal burn scar management has the potential to markedly improve the lives of children, but can require substantial healthcare resources. The study aimed to examine the cost-effectiveness of three scar management interventions: pressure garment; topical silicone gel; combined pressure garment and topical silicone gel therapy, alongside a randomised controlled trial of these interventions. Participants were children (n = 153) referred for burn scar management following grafting, spontaneous healing after acute burn injury, or reconstructive surgery. Healthcare resource use was costed from a health service perspective (6-months post-burn time-horizon). The mean total scar management cost was lowest in the topical silicone gel group ($382.87 (95% CI $337.72, $443.29)) compared to the pressure garment ($1327.02 (95% CI $1081.46, $1659.95)) and combined intervention $1605.97 ($1077.65, $2694.23)) groups. There were no significant between-group differences in Quality Adjusted Life Year estimates. There was a 70% probability that topical silicone gel dominated pressure garment therapy (was cheaper and more effective), a 29% probability that pressure garment therapy dominated combined therapy, and a 63% probability that topical silicone gel dominated combined therapy. In conclusion, topical silicone gel was the cheaper intervention, and may be favoured in the absence of clear clinical effect favouring pressure garment therapy or a combination of these management approaches.Trial registration: ACTRN12616001100482 (prospectively registered).

One-session treatment compared with multisession CBT in children aged 7–16 years with specific phobias: the ASPECT non-inferiority RCT

Background

Up to 10% of children and young people have a specific phobia that can significantly affect their mental health, development and daily functioning. Cognitive–behavioural therapy-based interventions remain the dominant treatment, but limitations to their provision warrant investigation into low-intensity alternatives. One-session treatment is one such alternative that shares cognitive–behavioural therapy principles but has a shorter treatment period.

Objective

This research investigated the non-inferiority of one-session treatment to cognitive–behavioural therapy for treating specific phobias in children and young people. The acceptability and cost-effectiveness of one-session treatment were examined.

Design

A pragmatic, multicentre, non-inferiority randomised controlled trial, with embedded economic and qualitative evaluations.

Settings

There were 26 sites, including 12 NHS trusts.

Participants

Participants were aged 7–16 years and had a specific phobia defined in accordance with established international clinical criteria.

Interventions

Participants were randomised 1 : 1 to receive one-session treatment or usual-care cognitive–behavioural therapy, and were stratified according to age and phobia severity. Outcome assessors remained blind to treatment allocation.

Main outcome measures

The primary outcome measure was the Behavioural Avoidance Task at 6 months’ follow-up. Secondary outcomes included the Anxiety Disorder Interview Schedule, Child Anxiety Impact Scale, Revised Children’s Anxiety and Depression Scale, a goal-based outcome measure, Child Health Utility 9D, EuroQol-5 Dimensions Youth version and resource usage. Treatment fidelity was assessed using the Cognitive Behaviour Therapy Scale for Children and Young People and the One-Session Treatment Rating Scale.

Results

A total of 274 participants were recruited, with 268 participants randomised to one-session treatment (n = 134) or cognitive–behavioural therapy (n = 134). A total of 197 participants contributed some data, with 149 participants in the intention-to-treat analysis and 113 in the per-protocol analysis. Mean Behavioural Avoidance Task scores at 6 months were similar across treatment groups when both intention-to-treat and per-protocol analyses were applied [cognitive–behavioural therapy: 7.1 (intention to treat), 7.4 (per protocol); one-session treatment: 7.4 (intention to treat), 7.6 (per protocol); on the standardised scale adjusted mean difference for cognitive–behavioural therapy compared with one-session treatment –0.123, 95% confidence interval –0.449 to 0.202 (intention to treat), mean difference –0.204, 95% confidence interval –0.579 to 0.171 (per protocol)]. These findings were wholly below the standardised non-inferiority limit of 0.4, which suggests that one-session treatment is non-inferior to cognitive–behavioural therapy. No between-group differences in secondary outcome measures were found. The health economics evaluation suggested that, compared with cognitive–behavioural therapy, one-session treatment marginally decreased the mean service use costs and maintained similar mean quality-adjusted life-year improvement. Nested qualitative evaluation found one-session treatment to be considered acceptable by those who received it, their parents/guardians and clinicians. No adverse events occurred as a result of phobia treatment.

Limitations

The COVID-19 pandemic meant that 48 children and young people could not complete the primary outcome measure. Service waiting times resulted in some participants not starting therapy before follow-up.

Conclusions

One-session treatment for specific phobia in UK-based child mental health treatment centres is as clinically effective as multisession cognitive–behavioural therapy and highly likely to be cost-saving. Future work could involve improving the implementation of one-session treatment through training and commissioning of improved care pathways.

A Systematic Review of International Guidance for Self-Report and Proxy Completion of Child-Specific Utility Instruments

OBJECTIVES

This study aimed to identify and summarize published guidance and recommendations for child self- and proxy assessment of existing child-specific instruments of health-related quality of life (HRQoL) that are accompanied by utilities.

METHODS

A total of 9 databases plus websites of (1) health technology assessment and health economics outcomes research organizations and (2) instrument developers were systematically searched. Studies were included if they reported guidance for child self- and proxy assessment for child populations (0-18 years old). Three reviewers independently screened titles, abstracts, and full-text reviews against the inclusion criteria. Key features of the guidance identified were summarized.

RESULTS

A total of 19 studies met the inclusion criteria. In general, journal articles provided little guidance on child self- and proxy assessment, with the majority focused on instrument development and psychometric performance more broadly. Instrument developers' websites provided more guidance for child self- and proxy reports with specific guidance found for the EQ-5D-Y and the Pediatric Quality of Life Inventory. This guidance included the minimum age for self-report and mode of administration; recommended proxy types, age range of child for whom proxy report can be completed, and target population; and recall period. Websites of leading organizations provided general guidance on HRQoL evaluation in children but lacked specific guidance about self- and proxy completion.

CONCLUSIONS

EQ-5D-Y and Pediatric Quality of Life Inventory developers' websites provided the most comprehensive guidance for self-report and proxy report of their respective instruments. More evidence is required for developing best practice guidance on why, when, and how to use self- and proxy reports in assessing HRQoL in child populations.

Time-efficient physical activity intervention for older adolescents with disability: rationale and study protocol for the Burn 2 Learn adapted (B2La) cluster randomised controlled trial

INTRODUCTION

Physical activity declines during adolescence, with the lowest levels of activity observed among those with disability. Schools are ideal settings to address this issue; however, few school-based interventions have been specifically designed for older adolescents with disability. Our aim is to investigate the effects of a school-based physical activity programme, involving high-intensity interval training (HIIT), on physical, mental and cognitive health in older adolescents with disability.

METHODS AND ANALYSIS

We will evaluate the Burn 2 Learn adapted (B2La) intervention using a two-arm, parallel group, cluster randomised controlled trial with allocation occurring at the school level (treatment or waitlist control). Secondary schools will be recruited in two cohorts from New South Wales, Australia. We will aim to recruit 300 older adolescents (aged 15-19 years) with disability from 30 secondary schools (10 in cohort 1 and 20 in cohort 2). Schools allocated to the intervention group will deliver two HIIT sessions per week during scheduled specialist support classes. The sessions will include foundational aerobic and muscle strengthening exercises tailored to meet student needs. We will provide teachers with training, resources, and support to facilitate the delivery of the B2La programme. Study outcomes will be assessed at baseline, 6 months (primary endpoint), and 9 months. Our primary outcome is functional capacity assessed using the 6 min walk/push test. Secondary outcomes include physical activity, muscular fitness, body composition, cognitive function, quality of life, physical literacy, and on-task behaviour in the classroom. We will also conduct economic and process evaluations to determine cost-effectiveness, programme acceptability, implementation, adaptability, and sustainability in schools.

ETHICS AND DISSEMINATION

This study has received approval from the University of Newcastle (H-2021-0262) and the New South Wales Department of Education (SERAP: 2021257) human research ethics committees. Findings will be published in peer-reviewed journals, and key stakeholders will be provided with a detailed report following the study.

Cost-effectiveness of home-based care of febrile neutropenia in children with cancer

INTRODUCTION

Home-based treatment of febrile neutropenia (FN) in children with cancer with oral or intravenous antibiotics is safe and effective. There are limited data on the economic impact of this model of care. We evaluated the cost-effectiveness of implementing an FN programme, incorporating home-based intravenous antibiotics for carefully selected patients, in a tertiary paediatric hospital.

METHODS

A decision analytic model was constructed to compare costs and outcomes of the home-based FN programme, with usual in-hospital treatment with intravenous antibiotics. The programme included a clinical decision rule to stratify patients by risk for severe infection and home-based eligibility criteria using disease, chemotherapy and patient-level factors. Health outcomes (quality of life) and probabilities of FN risk classification and home-based eligibility were based on prospectively collected data between 2017 and 2019. Patient-level costs were extracted from hospital administrative records. Cost-effectiveness was expressed as the incremental cost per quality-adjusted life year (QALY).

FINDINGS

The mean health care cost of home-based FN treatment in low-risk patients was Australian dollars (A$) 7765 per patient compared to A$20,396 for in-hospital treatment (mean difference A$12,632 [95% CI: 12,496-12,767]). Overall, the home-based FN programme was the dominant strategy, being more effective (0.0011 QALY [95% CI: 0.0011-0.0012]) and less costly. Results of the model were most sensitive to proportion of children eligible for home-based care programme.

CONCLUSION

Compared to in-hospital FN care, the home-based FN programme is cost-effective, with savings arising from cheaper cost of caring for children at home. These savings could increase as more patients eligible for home-based care are included in the programme.

Implications of providing wrist-hand orthoses for children with cerebral palsy: evidence from a randomised controlled trial

PURPOSE

To investigate the effects of providing rigid wrist-hand orthoses plus usual multidisciplinary care, on reducing hand impairments in children with cerebral palsy.

METHODS

A pragmatic, multicentre, assessor-blinded randomised controlled trial aimed to enrol 194 children aged 5-15 years, with wrist flexor Modified Ashworth Scale score ≥1. Randomisation with concealed allocation was stratified by study site and passive wrist range. The treatment group received a rigid wrist-hand orthosis, to wear ≥6 h per night for 3 years. Analysis included repeated measures mixed-effects linear regression models, using intention-to-treat principles.

RESULTS

The trial stopped early due to insufficient recruitment: 74 children, across all Manual Ability Classification System levels, were randomised (n = 38 orthosis group; n = 36 control). Mean age was 10.2 (SD 3.1) years (orthosis group) and 9.1 (SD 2.8) years (control). Data showed some evidence that rigid wrist-hand orthosis impacted passive wrist extension with fingers extended in the first year [mean difference between-groups at 6 months: 13.15° (95%CI: 0.81-25.48°, p = 0.04); 12 months: 20.94° (95%CI: 8.20-33.69°, p = 0.001)]. Beyond 18 months, participant numbers were insufficient for conclusive findings.

CONCLUSION

The study provided detailed data about short- and long-term effects of the wrist-hand orthosis and highlighted challenges in conducting large randomised controlled trials with this population. Trial Registration: Australia and New Zealand Clinical Trials Registry: U1111-1164-0572 IMPLICATIONS FOR REHABILITATIONThere may be incremental benefit, for children with cerebral palsy, at 6 and 12 months on passive wrist range from wearing a rigid wrist-hand orthosis designed according to this protocol.The rigid-wrist-hand orthosis evaluated in this study, which allowed for some tailoring for individual children's presentations, differed in design from past recommendations for "resting hand" positioning.Longitudinal follow up of children with cerebral palsy prescribed a rigid wrist-hand orthosis is essential to monitor any benefit.Minor adverse events were commonly experienced when wearing the orthosis and should be discussed prior to prescription of a rigid wrist-hand orthosis.

Connectomic profiling and Vagus nerve stimulation Outcomes Study (CONNECTiVOS): a prospective observational protocol to identify biomarkers of seizure response in children and youth

INTRODUCTION

Vagus nerve stimulation (VNS) is a neuromodulation therapy that can reduce the seizure burden of children with medically intractable epilepsy. Despite the widespread use of VNS to treat epilepsy, there are currently no means to preoperatively identify patients who will benefit from treatment. The objective of the present study is to determine clinical and neural network-based correlates of treatment outcome to better identify candidates for VNS therapy.

METHODS AND ANALYSIS

In this multi-institutional North American study, children undergoing VNS and their caregivers will be prospectively recruited. All patients will have documentation of clinical history, physical and neurological examination and video electroencephalography as part of the standard clinical workup for VNS. Neuroimaging data including resting-state functional MRI, diffusion-tensor imaging and magnetoencephalography will be collected before surgery. MR-based measures will also be repeated 12 months after implantation. Outcomes of VNS, including seizure control and health-related quality of life of both patient and primary caregiver, will be prospectively measured up to 2 years postoperatively. All data will be collected electronically using Research Electronic Data Capture.

ETHICS AND DISSEMINATION

This study was approved by the Hospital for Sick Children Research Ethics Board (REB number 1000061744). All participants, or substitute decision-makers, will provide informed consent prior to be enrolled in the study. Institutional Research Ethics Board approval will be obtained from each additional participating site prior to inclusion. This study is funded through a Canadian Institutes of Health Research grant (PJT-159561) and an investigator-initiated funding grant from LivaNova USA (Houston, TX; FF01803B IIR).

Relationship Between Weight Status and Health-Related Quality of Life in School-age Children in China

Background: Some studies from high-income countries suggest that overweight and/or obesity in children are negatively associated with health-related quality of life (HRQOL). However, the relationship between weight status and HRQOL is not well established in China, where obesity trends follow a different pattern compared with high-income countries. The risk of obesity is greater in children from higher socioeconomic backgrounds and higher in boys compared with girls. Objective: The aim of this study was to examine the relationship between weight status and HRQOL in children between 6 and 7 years old in this unique country context. Methods: Baseline HRQOL and demographic data were collected from children recruited to the CHIRPY DRAGON obesity prevention trial in China. HRQOL was measured using the Chinese version of the Child Health Utility-9D (CHU-9D-CHN) and the Pediatric Quality of Life Inventory™ (PedsQL™) instruments. CHU-9D-CHN utility scores were generated using 2 scoring algorithms (UK and Chinese tariffs). Height and weight measures were taken at school by trained researchers using standardized methods, and BMI z scores were calculated using the World Health Organization 2007 growth charts. The relationship between HRQOL and weight status was examined using multivariable analyses, adjusting for age, gender, and socioeconomic status. Results: Full data were available for 1539 children (mean age, 6 years). In both unadjusted and adjusted analyses, HRQOL, using both the CHU-9D-CHN and the PedsQL™, was marginally higher in children who were overweight or living with obesity compared with children with healthy weight, although this difference did not reach statistical significance. Separate analyses and models by gender showed that the relationship between weight status and HRQOL scores was similar in boys and girls. Conclusions: Our results suggest no statistically significant difference in HRQOL between children with overweight/obesity compared with those with healthy weight. These results have implications for the methods of economic evaluation for obesity treatment and prevention interventions within this population cohort and country setting, as there appears to be no discernible consequences on children's HRQOL from living with overweight and obesity.

Protocol for a randomised controlled feasibility study examining the efficacy of brief cognitive therapy for the treatment of panic disorder in adolescents (PANDA)

BACKGROUND

Panic disorder occurs in between 1 and 3% of adolescents, is associated with high levels of co-morbidity, and without treatment, appears to have a chronic course. To improve access to effective psychological interventions, briefer versions of cognitive behaviour therapy (CBT) have been developed and evaluated for preadolescent children with anxiety disorders. However, there are currently no brief evidence-based CBT interventions for adolescents with anxiety disorders that can be delivered in less than eight sessions. Given that a brief version of cognitive therapy has been shown to be effective in adults with panic disorder, it is possible that an adapted version could be effective for adolescents with panic disorder.

METHODS

The study will examine whether a definitive trial can be conducted, based on a single-centre feasibility randomised controlled trial using several well-defined criteria. Between 30 and 48 young people (age 11-18 years) who meet diagnostic criteria for panic disorder, attending a routine clinical service will be randomly allocated to receive either (i) brief cognitive therapy or (ii) a general form of CBT treatment that is more commonly used for adolescents with anxiety disorders. Both will be delivered 1:1 by a therapist and involve five treatment sessions and two booster sessions. Young people's outcomes will be assessed at the end of treatment and at 3-month follow-up, and qualitative interviews will be conducted to examine acceptability. We will also explore outcomes 1 year after the completion of treatment.

DISCUSSION

This study will test the feasibility of a randomised controlled trial to compare brief cognitive therapy to a general form of CBT for adolescents with panic disorder in the UK. The outputs from the study will provide a clear indication of the feasibility of a future definitive trial and, if indicated, the critical resources that will be required and key information to inform the design and maximise the successful completion of the trial. This has the potential to bring direct benefits to young people and their families, as well as services and society more broadly.

Study protocol for the Multimodal Approach to Preventing Suicide in Schools (MAPSS) project: a regionally based randomised trial of an integrated response to suicide risk among secondary school students

BACKGROUND

Suicide is the leading cause of death among young Australians, accounting for one-third of all deaths in those under 25. Schools are a logical setting for youth suicide prevention activities, with universal, selective and indicated approaches all demonstrating efficacy. Given that international best practice recommends suicide prevention programmes combine these approaches, and that to date this has not been done in school settings, this study aims to evaluate a suicide prevention programme incorporating universal, selective and indicated components in schools.

METHODS

This study is a trial of a multimodal suicide prevention programme for young people. The programme involves delivering universal psychoeducation (safeTALK) to all students, screening them for suicide risk, and delivering internet-based Cognitive Behavioural Therapy (Reframe IT) to those students identified as being at high risk for suicide. The programme will be trialled in secondary schools in Melbourne, Australia, and target year 10 students (15 and 16 year-olds). safeTALK and screening will be evaluated using a single group pre-test/post-test case series, and Reframe IT will be evaluated in a Randomised Controlled Trial. The primary outcome is change in suicidal ideation; other outcomes include help-seeking behaviour and intentions, and suicide knowledge and stigma. The programme's cost-effectiveness will also be evaluated.

DISCUSSION

This study is the first to evaluate a suicide prevention programme comprising universal, selective and indicated components in Australian schools. If the programme is found to be efficacious and cost-effective, it could be more widely disseminated in schools and may ultimately lead to reduced rates of suicide and suicidal behaviour in school students across the region.

The Role of Parent Engagement in a Web-Based Preventive Parenting Intervention for Child Mental Health in Predicting Parenting, Parent and Child Outcomes

Although parents’ engagement in parenting programmes has frequently been posited to influence the efficacy and dissemination of these programmes, its relationship with intervention outcomes in parenting programmes is understudied. This study examined the predictive value of parental engagement on preventive parenting outcomes in a tailored online parenting programme aimed at enhancing parental protective factors and reducing risk factors for child depression and anxiety disorders. The present study also explored the associations between parental engagement and other parent, child and family outcomes. Data were collected from a community sample of 177 parents who received a tailored online parenting programme (‘Parenting Resilient Kids’; PaRK) and their children as part of a randomised controlled trial. Participants completed measures on parenting, child anxiety and depressive symptoms, health-related quality of life and family functioning on three occasions. Multiple regressions showed that parental engagement explained additional variance in preventive parenting (most proximal outcomes) at post-intervention and 12-month follow-up. Indicators of higher levels of parental engagement, operationalised by greater proportions of recommended programme modules and intended goals completed, uniquely predicted higher levels of preventing parenting. Higher levels of parental engagement also predicted higher levels of parental acceptance and parental psychosocial health-related quality of life, lower levels of parental psychological control and lower levels of impairments in child health-related quality of life. However, parental engagement did not explain additional variance in parent or child reported anxiety or depressive symptoms. This study provides support for the role of parental engagement in facilitating parenting changes in parenting-focused interventions.

The relationship between physical and mental health multimorbidity and children's health-related quality of life

Purpose

To examine the relationships between physical health problems, and borderline or clinical levels of mental health symptoms and children’s health-related quality of life (HRQoL).

Methods

Data were from the Longitudinal Study of Australian Children (2004–2018). Parents reported on their child’s HRQoL (PedsQL), physical health problems and mental health symptoms (Strengths and Difficulties Questionnaire, SDQ). A pooled cross-sectional analysis using linear regressions examined the relationships between physical health and clinical/borderline mental health symptoms, individually and when multi-morbid, and children’s HRQoL, and whether these relationships vary by a range of child, family and social factors.

Results

The sample comprised 47,567 observations of children aged 4–17 years. Borderline and clinical levels of mental health symptoms were associated with significantly lower HRQoL, equal to more than two-times (10.5 points) and more than three-times (16.8 points) the clinically meaningful difference, respectively. This was a larger difference than that associated with physical health problems (4.4 points). We found a significant interaction effect between physical health problems and clinical mental health symptoms which was associated with even poorer HRQoL after accounting for the individual relationships of both problems. Mental health problems were associated with poorer HRQoL for older versus younger children; and the interaction effect was significant for boys but not girls.

Conclusion

Findings highlight the importance of identifying and addressing mental health symptoms in children of all ages, even if these problems do not meet formal clinical criteria. Particular attention should be paid to the mental health and HRQoL of children with physical–mental multimorbidity, who are at risk of disproportionately poorer HRQoL.

Ongoing physical and mental health problems are common in children and adolescents and, often, children can experience both problems together. Mental and physical health problems can have wide impacts for the child, including their health-related quality of life (HRQoL), which is a measure of the way the child’s health impacts their emotional, social and physical functioning during their day-to-day life. Our study shows that children with high levels of mental health symptoms have much poorer HRQoL than their peers, and we provide new evidence that even milder mental health symptoms are associated with poorer HRQoL than in children with physical health problems. When children have both physical and mental health problems, they are at even greater risk of poorer HRQoL than would be expected. Based on our findings, we recommend that clinicians should monitor and address mental health symptoms in children as young as 4–7 years old, even if these symptoms are milder, and particular attention should be given to children with physical and mental health problems, who are at greater risk of poor HRQoL.

Daily low-dose prednisolone to prevent relapse of steroid-sensitive nephrotic syndrome in children with an upper respiratory tract infection: PREDNOS2 RCT

Background

Most children with steroid-sensitive nephrotic syndrome have relapses that are triggered by upper respiratory tract infections. Four small trials, mostly in children already taking maintenance corticosteroid in countries of different upper respiratory tract infection epidemiology, showed that giving daily low-dose prednisone/prednisolone for 5–7 days during an upper respiratory tract infection reduces the risk of relapse.

Objectives

To determine if these findings were replicated in a large UK population of children with relapsing steroid-sensitive nephrotic syndrome on different background medication or none.

Design

A randomised double-blind placebo-controlled trial, including a cost-effectiveness analysis.

Setting

A total of 122 UK paediatric departments, of which 91 recruited patients.

Participants

A total of 365 children with relapsing steroid-sensitive nephrotic syndrome (mean age 7.6 ± 3.5 years) were randomised (1 : 1) according to a minimisation algorithm based on background treatment. Eighty children completed 12 months of follow-up without an upper respiratory tract infection. Thirty-two children were withdrawn from the trial (14 prior to an upper respiratory tract infection), leaving a modified intention-to-treat analysis population of 271 children (134 and 137 children in the prednisolone and placebo arms, respectively).

Interventions

At the start of an upper respiratory tract infection, children received 6 days of prednisolone (15 mg/m2) or an equivalent dose of placebo.

Main outcome measures

The primary outcome was the incidence of first upper respiratory tract infection-related relapse following any upper respiratory tract infection over 12 months. The secondary outcomes were the overall rate of relapse, changes in background treatment, cumulative dose of prednisolone, rates of serious adverse events, incidence of corticosteroid adverse effects, change in Achenbach Child Behaviour Checklist score and quality of life. Analysis was by intention-to-treat principle. The cost-effectiveness analysis used trial data and a decision-analytic model to estimate quality-adjusted life-years and costs at 1 year, which were then extrapolated over 16 years.

Results

There were 384 upper respiratory tract infections and 82 upper respiratory tract infection-related relapses in the prednisolone arm, and 407 upper respiratory tract infections and 82 upper respiratory tract infection-related relapses in the placebo arm. The number of patients experiencing an upper respiratory tract infection-related relapse was 56 (42.7%) and 58 (44.3%) in the prednisolone and placebo arms, respectively (adjusted risk difference –0.024, 95% confidence interval –0.14 to 0.09; p = 0.70). There was no evidence that the treatment effect differed when data were analysed according to background treatment. There were no significant differences in secondary outcomes between treatment arms. Giving daily prednisolone at the time of an upper respiratory tract infection was associated with increased quality-adjusted life-years (0.9427 vs. 0.9424) and decreased average costs (£252 vs. £254), when compared with standard care. The cost saving was driven by background therapy and hospitalisations after relapse. The finding was robust to sensitivity analysis.

Limitations

A larger number of children than expected did not have an upper respiratory tract infection and the sample size attrition rate was adjusted accordingly during the trial.

Conclusions

The clinical analysis indicated that giving 6 days of daily low-dose prednisolone at the time of an upper respiratory tract infection does not reduce the risk of relapse of steroid-sensitive nephrotic syndrome in UK children. However, there was an economic benefit from costs associated with background therapy and relapse, and the health-related quality-of-life impact of having a relapse.

Future work

Further work is needed to investigate the clinical and health economic impact of relapses, interethnic differences in treatment response, the effect of different corticosteroid regimens in treating relapses, and the pathogenesis of individual viral infections and their effect on steroid-sensitive nephrotic syndrome.

CHU9D Normative Data in Peruvian Adolescents

BACKGROUND

Due to the vulnerability to protective and risk factors during adolescence, there is a growing interest in the study of health-related quality of life (HRQoL) at this stage. The CHU9D is a generic and practical HRQoL instrument that provides values on all dimensions of self-perceived health, in addition to providing utilities and a cost-utility assessment fee, unlike other instruments. This study was conducted with an adolescent population in Peru. The main objective of this article is to report the normative values of the CHU9D questionnaire in Peruvian adolescents.

METHODS

The CHU9D questionnaire was administered to Peruvian adolescent students. A total of 1229 young people participated in the survey. The CHU9D score was reflected as a function of gender, age, weight, height, and educational level.

RESULTS

The mean CHU9D utility index for the total sample was 0.890; this rating was significantly better for boys with 0.887 and girls with 0.867. The ceiling effect was higher for male adolescents with 32.6 than for female adolescents.

CONCLUSIONS

The results of the present study show that adolescents in school show a positive perception of HRQoL. It is also concluded that the CHU9D instrument can be effectively applied to economic evaluations for interventions to improve the quality of life of adolescents.

Protocol for the RELATE trial: a feasibility and pilot randomised controlled trial of a low-intensity group intervention for young people in care with elevated posttraumatic stress symptoms

Introduction

Young people in out-of-home care have often experienced trauma, such as direct maltreatment or witnessing violence. There is good evidence that rates of mental health difficulties are high in this group, including posttraumatic stress disorder (PTSD), a trauma-specific mental health outcome. There remains less evidence to guide how to effectively address elevated PTSD symptoms (PTSS) in these young people, particularly in ways that are feasible and scalable for stretched social-care and mental health services.

Methods and analysis

This protocol describes a feasibility study comprising a pilot two-arm randomised controlled trial (RCT). Participants (N = 50) will be randomised to either (a) a group-based trauma-focused programme (Teaching Recovery Techniques), delivered by mental health practitioners both online and in-person, or (b) care-as-usual. Primarily, the trial aims to explore the key feasibility and protocol acceptability questions, including rates of recruitment and retention, as well as the acceptability of the intervention (particularly the online delivery format) to participants and services. In addition, outcomes including PTSS (primary clinical outcome), depression and functioning will be assessed at baseline (pre-randomisation), post-intervention and at a 3-month follow-up.

Ethics and dissemination

Ethical approval has been received from the Health Research Authority (Wales REC1 Ref 20/WA/0100) and University, with further approval from the host trust and social care site. The results will inform the design of a definitive RCT. Dissemination will include peer-reviewed journal articles reporting the qualitative and quantitative results, as well as presentations at conferences and lay summaries.

Does depression moderate the relationship between pain and suicidality in adolescence? A moderated network analysis

BACKGROUND

Whilst growing research suggests that pain is associated with suicidality in adolescence, it remains unclear whether this relationship is moderated by co-morbid depressive symptoms. The present study aimed to investigate whether the pain-suicidality association is moderated by depressive symptoms.

METHODS

We performed secondary analyses on cross-sectional, pre-intervention data from the 'My Resilience in Adolescence' [MYRIAD] trial (ISRCTN ref: 86619085; N=8072, 11-15 years). Using odds ratio tests and (moderated) network analyses, we investigated the relationship between pain and suicidality, after controlling for depression, anxiety, inhibitory control deficits and peer problems. We investigated whether depression moderates this relationship and explored gender differences.

RESULTS

Overall, 20% of adolescents reported suicidality and 22% reported pain, whilst nine percent of adolescents reported both. The experience of pain was associated with a four-fold increased risk of suicidality and vice versa (OR=4.00, 95%-CI=[3.54;4.51]), with no gender differences. This cross-sectional association remained significant after accounting for depression, anxiety, inhibitory control deficits and peer problems (aOR=1.39). Depression did not moderate the pain-suicidality association.

LIMITATIONS

The item-based, cross-sectional assessment of pain and suicidality precludes any conclusions about the direction of the effects and which aspects of suicidality and pain may drive this association.

CONCLUSIONS

Our findings underscore the need to consider pain as an independent risk correlate of suicidality in adolescents. Longitudinal research should examine how this relationship develops during adolescence. Clinically, our findings emphasise the need to assess and address suicidality in adolescents with pain, even in the absence of depressive symptoms.
