Finding out what matters: validity of quality of life measurement in young people with ASD

Using Life Course Theory to Explore the Association Between Autistic Traits, Child, Family, and School Factors and the Successful Transition to Secondary School

Life Course Theory contends that school transitions can interrupt academic and wellbeing trajectories, depending on child, family, and school factors. Hierarchical regression analyses examined how autistic traits were associated with school transition outcomes. Autistic traits explained 12% of the variance in Quality of Life (QOL), 24% of the variance in mental health and 9% of the variance in school belonging. When autistic traits were accounted for, gender was a significant predictor of changes in QOL whereas changes in school belonging were predicted by cognitive functioning, parent education, school attendance and school refusal. Changes in mental health after transition were mostly predicted by family factors including family structure, family functioning and parent education but were also significantly predicted by sleep problems.

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.

A systematic review and meta-synthesis on perspectives of autistic young people and their parents on psychological well-being

Autistic adolescents are at increased risk of developing mental health problems. Improving psychological well-being could reduce the likelihood of such problems developing. Research has tended to prioritise the voices of non-autistic people and has neglected to consult autistic young people themselves. Our meta-synthesis aimed to systematically review qualitative research on the perspectives of autistic young people and their parents on the lived experience of psychological well-being. We conducted a pre-planned systematic search which identified 2552 papers, with 37 of those meeting full inclusion criteria. Included papers were published between 2008 and 2023, with three-quarters published since 2018. We extracted qualitative data from each paper pertaining to the lived experience of psychological well-being in autistic young people and conducted a thematic synthesis. We identified three themes; Walking a tightrope: the need for growth versus recharging through rest and familiarity; Developing a positive sense of self in the social world; Internally driven sources of happiness. Psychological interventions aiming to improve well-being in autistic young people should respect their autonomy and need for rest whilst encouraging growth and skills development, provide opportunities to understand social needs and differences, and promote opportunities to enjoy special interests.

The physical and psychosocial impact of a school-based running programme for adolescents with disabilities

BACKGROUND

Adolescents with disabilities have fewer opportunities to participate in community-based fitness programmes. The purpose of this study was to examine the impact of a school-based running programme at a local middle school in Lebanon, Pennsylvania, on fitness and quality of life (QoL) in children with physical and cognitive disabilities in a life-skills classroom.

METHODS

Nineteen adolescents with diagnosed disabilities including intellectual disability (ID), autism spectrum disorder and Down syndrome were recruited from three life-skills classrooms to participate in a school-based running programme. The programme was designed to be implemented two times/week for 6 weeks by classroom teachers/aides. Physical therapy faculty and students developed the programme and assisted with implementation. Each session lasted 30 min, consisting of a warm-up and cooldown, relay races, games and timed runs. Pre- and post-test measures included physiological cost index (PCI) and Paediatric Quality of Life Inventory™ (PedsQL™). Pre- and post-test data were compared using Wilcoxon signed rank tests. Each week participants also completed a training log to reflect on the activity for the day.

RESULTS

Participants demonstrated significant improvements in PCI (P = 0.028) and the PedsQL™ (P = 0.008) following the running programme.

CONCLUSIONS

Results of this study suggest that participation in a 6-week school-based running programme may improve fitness and QoL in adolescents with disabilities.

Investigating the quality of life for children with autism spectrum disorder scale using Rasch methodology

Our purpose in this study was to provide additional psychometric evidence of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We used Rasch modeling to investigate the QOLASD-C functioning, the characteristics of the items comprising the scale, and the item functioning across subgroups of children with ASD based on gender and race/ethnicity. Results showed that QOLASD-C was unidimensional, met the local independence assumption, and measured quality of life (QOL). The items showed excellent fit to the model and good discriminating ability between low and high QOL. Most items showed a moderate difficulty level. No differential item functioning was observed based on children's gender and race/ethnicity. Implications for research and practice are discussed.

Piloting a Home Visual Support Intervention with Families of Autistic Children and Children with Related Needs Aged 0-12

Visual supports are an important intervention for autistic individuals and others with neurodevelopmental differences. However, families often report limited access to visual supports and lack of information and confidence in their use at home. This pilot study aimed to evaluate the feasibility and effectiveness of a home-based visual supports intervention.

METHODS

29 families with children (n = 20 males; mean age 6.59 years [Range 3.64-12.21 years SD 2.57]) receiving support for autism or related needs participated in the study. Parents engaged in an individualised assessment and intervention process through home visits, completing pre- and post-measures. Qualitative methods were used to explore the parents' experiences of the intervention.

RESULTS

The intervention led to a statistically significant improvement in parent-reported quality of life (t28 = 3.09, p = 0.005) and parent-reported perception of autism-specific difficulties (t28 = 2.99, p = 0.006). Parents also reported improved access to resources and relevant information and increased confidence in using visual supports at home. The home visit model was strongly supported by the parents.

CONCLUSION

The results provide initial evidence of the acceptability, practicality, and utility of the home-based visual supports intervention. These findings suggest that outreach into the family home may be a beneficial mechanism for delivering interventions related to visual supports. This study highlights the potential of home-based interventions to improve access to resources and information for families and the importance of visual supports in the home setting.

Adolescents with emotional and behavioral disorders face known academic challenges and poor life outcomes. It was imperative to explore and find if the new diagnostic criterion for diagnosing autism profoundly affects educational outcomes and resilience in individuals diagnosed with co-occurring autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD). The literature is robust on the impact of adverse childhood experiences (ACEs) on educational outcomes and resilience in adolescents with no history of disability. Still, there remains a dearth of literature explaining, with no ambiguity, the complex relationships between ACEs and resilience, school engagement, and success in individuals with co-occurring ASD and ADHD. This study reviews the existing scholarships on the topic. The significance of this review is that it informs healthcare providers, rehabilitation counselors, and educators about the need for early identification of individuals with ASD and ADHD with a background in ACEs. This will enable interventions early enough to ensure they are more resilient and can obtain improved success in school-related and outside-school activities and eventually improved quality of life.

Cross-Cultural Validation of Health and Quality of Life Measures for Children in Hong Kong

Objective

The Pediatric Quality of Life Inventory (PedsQL™) 4.0 is a health-related quality of life (HRQOL) measure designed for clinical practice and research, health policy evaluation, and general population surveys. There is a dearth of instruments measuring quality of life in children which are available in Chinese and validated for Chinese populations. Therefore, this study attempted to establish the Hong Kong populations' norms for the Chinese version of PedsQL™ and examined the psychometric properties of the measure for this population.

Methods

Sixty-nine children (aged 7 to 12 years) and their parents completed the child self-report and the parent proxy report, respectively, of the PedsQL™ 4.0 Generic Module. To evaluate construct validity, a group comparison of children with special educational needs (SEN) (n = 21) and those with typical development (TD) (n = 48) was conducted. Differences based on age group and gender and parent–child agreement on the perception of the child's HRQOL were also examined.

Results

Children with SEN had a lower quality of life perception than those with TD in the physical, social, and schooling domains. No significant differences in emotional health were found between the two groups. The differences between the children with SEN and with TD varied based on age group and gender. The differences between the parents' and children's perceptions of the children's HRQOL were insignificant in this sample.

Conclusion

Norms for the Chinese version of the PedsQL™ 4.0 Generic Module for the Hong Kong population were established in the study, and both the child self-report and parent proxy report were found to be reliable and valid for this population.

Conceptualization of quality of life in autistic individuals

The present study examines to what extent two core characteristics of the quality of life (QoL) construct were incorporated in the field of autism: (1) its subjective nature; and (2) its multidimensionality. Therefore, we reviewed 174 articles examining QoL in individuals with autism. The review showed parents reporting a lower QoL compared with autistic individuals themselves, especially on internal domains. This may suggest different expectations about what a good QoL may entail. Such an underestimation of QoL by others is commonly observed in individuals with disabilities (the so-called 'disability paradox'). For the multidimensionality of the QoL construct, our findings suggest that the narrower (and more unidimensional) construct of health-related QoL is often measured instead of QoL. Additionally, a substantial proportion of items did not measure QoL, but they evaluated characteristics that may or may not have an impact on QoL. Researchers and clinicians should be aware that QoL domains are selected and operationalized differently by different instruments. QoL may benefit from an exclusive focus on subjective aspects, which can be measured alongside more normative, objective characteristics of individuals or their environment.

The Quality of Life for Children with Autism Spectrum Disorder Scale: Factor Analysis, MIMIC Modeling, and Cut-Off Score Analysis

Our purpose in this study was to further examine the psychometric properties of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We first investigated the factor structure and the internal consistency of the scale. The bifactor model showed good fit and strong reliability. Second, we used multiple-indicators multiple-causes (MIMIC) modeling to examine the associations between demographic variables and the QOLASD-C dimensions. Results showed differences on overall QOL based on age, race/ethnicity, and autism spectrum disorder severity, but no relationships with gender. All demographic variables were associated with one or all three subscales (i.e., interpersonal relationships, self-determination, emotional well-being) of the QOLASD-C. Third, an optimal cut-off score of 37 was identified. Implications for research and practice are discussed.

Defining and Measuring Indices of Happiness and Unhappiness in Children Diagnosed with Autism Spectrum Disorder

Improving quality of life (QoL) is the goal of behavior analytic services, but there can be barriers to assessing the QoL of autistic children due to characteristics inherent in the condition. Given that happiness is a fundamental element of QoL, previous research has relied on behavioral indicators of mood (e.g., smiling, crying) to evaluate the overall QoL of disabled individuals. However, the use of these traditional indices may not accurately reflect the emotional well-being of autistic individuals, who are known to engage in idiosyncratic mood indicators. The current study replicated selected procedures from Parsons et al. (2012) to identify and validate the unique mood indicators of young autistic children. The study showed that individualized indices of happiness and unhappiness could be operationally defined and reliably measured among these children. Key findings and limitations of this study are discussed, and the implications of these findings are presented.

Psychometric Performance of HRQoL Measures: An Australian Paediatric Multi-Instrument Comparison Study Protocol (P-MIC)

Background: There is a lack of psychometric evidence about pediatric health-related quality of life (HRQoL) instruments. Evidence on cost effectiveness, involving the measurement of HRQoL, is used in many countries to make decisions about pharmaceuticals, technologies, and health services for children. Additionally, valid instruments are required to facilitate accurate outcome measurement and clinical decision making. A pediatric multi instrument comparison (P-MIC) study is planned to compare the psychometric performance and measurement characteristics of pediatric HRQoL instruments. Methods: The planned P-MIC study will collect data on approximately 6100 Australian children and adolescents aged 2–18 years via The Royal Children’s Hospital Melbourne and online survey panels. Participants will complete an initial survey, involving the concurrent collection of a range of pediatric HRQoL instruments, followed by a shorter survey 2–8 weeks later, involving the collection of a subset of instruments from the initial survey. Children aged ≥7 years will be asked to self-report HRQoL. Psychometric performance will be assessed at the instrument, domain, and item level. Conclusions: This paper describes the methodology of the planned P-MIC study, including benefits, limitations, and likely challenges. Evidence from this study will guide the choice of HRQoL measures used in clinical trials, economic evaluation, and other applications.

Searching for What Really Matters: A Thematic Analysis of Quality of Life among Preschool Children on the Autism Spectrum

Quality of life (QoL) is an essential measure when assessing health interventions. Most early interventions for preschool children on the spectrum evaluate the effects on autism symptoms. However, researchers increasingly believe that good interventions should also improve the QoL of these children. Domains of QoL among preschool children on the autism spectrum have not previously been researched. We interviewed adults on the spectrum to explore early childhood experiences that made their lives satisfying. Our data revealed four major themes: interests, environmental regularity, sensory differences and social interactions. This study provides the first insights on aspects of life important to pre-schoolers on the spectrum. Findings will contribute to developing items for a measure of QoL among this population.

COVID-19 health and social care access for autistic people: European policy review

BACKGROUND

The global COVID-19 pandemic has had an unprecedented impact on European health and social care systems, with demands on testing, hospital and intensive care capacity exceeding available resources in many regions. This has led to concerns that some vulnerable groups, including autistic people, may be excluded from services.

METHODS

We reviewed policies from 15 European member states, published in March-July 2020, pertaining to (1) access to COVID-19 tests; (2) provisions for treatment, hospitalisation and intensive care units (ICUs); and (3) changes to standard health and social care. In parallel, we analysed survey data on the lived experiences of 1301 autistic people and caregivers.

RESULTS

Autistic people experienced significant barriers when accessing COVID-19 services. First, despite being at elevated risk of severe illness due to co-occurring health conditions, there was a lack of accessibility of COVID-19 testing. Second, many COVID-19 outpatient and inpatient treatment services were reported to be inaccessible, predominantly resulting from individual differences in communication needs. Third, ICU triage protocols in many European countries (directly or indirectly) resulted in discriminatory exclusion from lifesaving treatments. Finally, interruptions to standard health and social care left over 70% of autistic people without everyday support.

CONCLUSIONS

The COVID-19 pandemic has further exacerbated existing healthcare inequalities for autistic people, probably contributing to disproportionate increases in morbidity and mortality, mental health and behavioural difficulties, and reduced quality of life. An urgent need exists for policies and guidelines on accessibility of COVID-19 services to be updated to prevent the widespread exclusion of autistic people from services, which represents a violation of international human rights law.

A Psychometric Evaluation of the Quality of Life for Children with Autism Spectrum Disorder Scale

Our purpose in this study was to validate the Quality of Life for Children with Autism Spectrum Disorder scale. We first conducted an exploratory factor analysis to examine the factor structure. Results suggested that a three-factor model (Interpersonal Relationships, Self-Determination, and Emotional Well-Being) should be retained. Next, we conducted a confirmatory factor analysis to compare a higher-order factor model and additional models. Results showed acceptable model fit for the higher-order factor model. The scale had excellent reliability (α = .90) for the overall scale and for the three subscales (Interpersonal Relationships, α = .87; Self-Determination, α = .81; and Emotional Well-Being, α = .66). The 16-item scale showed convergent and divergent validity. Implications for future research and practice are discussed.

Addressing Quality of Life of Children With Autism Spectrum Disorder and Intellectual Disability

Despite the advances on the assessment of quality of life, this concept is barely studied and is riddled with important limitations for those with autism spectrum disorder (ASD). This article is aimed at validating a questionnaire to assess quality of life of children with ASD and intellectual disability (ID). Based on the KidsLife Scale, geared toward people with ID, the most reliable items for those with ASD were selected. Study participants were 420 persons, from 4 to 21 years old. Results indicated that the KidsLife-ASD Scale measured eight intercorrelated domains, had good reliability, and exhibited adequate evidences of validity. KidsLife-ASD emerges as a helpful tool to guide person-centered planning addressed at improving quality of life.

Developing dimensions for a new preference-based quality of life instrument for older people receiving aged care services in the community

Purpose

To identify the salient quality of life characteristics relevant to older people in receipt of community aged care services in order to develop dimensions for a draft descriptive system for a new preference-based quality of life instrument.

Methods

Forty-one in-depth semi-structured interviews were undertaken with older people (65 years and over) receiving community aged care services across three Australian states to explore quality of life characteristics of importance to them. The data were analysed using framework analysis to extract broader themes which were organised into a conceptual framework. The data were then summarised into a thematic chart to develop a framework matrix which was used to interpret and synthesise the data. Care was taken throughout to retain the language that older people had adopted during the interviews to ensure that appropriate language was used when identifying and developing the quality of life dimensions.

Results

The analysis resulted in the identification of five salient quality of life dimensions: independence, social connections, emotional well-being, mobility, and activities.

Conclusion

This research finds that quality of life for older people accessing aged care services goes beyond health-related quality of life and incorporates broader aspects that transcend health. The findings represent the first stage in a multiphase project working in partnership with older people to develop a new preference-based instrument of quality of life for informing quality assessment and economic evaluation in community aged care. In future work, draft items will be developed from these dimensions and tested in face validity interviews before progressing to further psychometric testing.

The Association Between Autism Spectrum Traits and the Successful Transition to Mainstream Secondary School in an Australian School-Based Sample

The transition to secondary school is an important educational milestone impacting wellbeing and academic achievement. Students with Autism Spectrum Disorder may be vulnerable during transition however little is known about how Autism Spectrum (AS) traits influence transition outcomes. Generalised estimating equations were used to examine how AS traits were associated with four indicators of successful transition in a school-based sample of 51 students. Higher AS traits were associated with lower quality of life, school belonging and mental health, however the hypothesised decline after school transition was not supported. Characteristics of both the primary and secondary school appeared to be contributing to the wellbeing of students with high AS traits which could be clarified by further investigation with a larger sample.

Assessing quality of life in psychosocial and mental health disorders in children: a comprehensive overview and appraisal of generic health related quality of life measures

BACKGROUND

Mental health problems often arise in childhood and adolescence and can have detrimental effects on people's quality of life (QoL). Therefore, it is of great importance for clinicians, policymakers and researchers to adequately measure QoL in children. With this review, we aim to provide an overview of existing generic measures of QoL suitable for economic evaluations in children with mental health problems.

METHODS

First, we undertook a meta-review of QoL instruments in which we identified all relevant instruments. Next, we performed a systematic review of the psychometric properties of the identified instruments. Lastly, the results were summarized in a decision tree.

RESULTS

This review provides an overview of these 22 generic instruments available to measure QoL in children with psychosocial and or mental health problems and their psychometric properties. A systematic search into the psychometric quality of these instruments found 195 suitable papers, of which 30 assessed psychometric quality in child and adolescent mental health.

CONCLUSIONS

We found that none of the instruments was perfect for use in economic evaluation of child and adolescent mental health care as all instruments had disadvantages, ranging from lack of psychometric research, no proxy version, not being suitable for young children, no age-specific value set for children under 18, to insufficient focus on relevant domains (e.g. social and emotional domains).

Interventions based on early intensive applied behaviour analysis for autistic children: a systematic review and cost-effectiveness analysis

BACKGROUND

Early intensive applied behaviour analysis-based interventions are intensive interventions for autistic children that are often delivered on a one-to-one basis for 20-50 hours per week.

OBJECTIVES

To evaluate the clinical effectiveness and cost-effectiveness of early intensive applied behaviour analysis-based interventions for autistic children, based on current evidence.

METHODS

A systematic review and individual participant data meta-analysis were conducted to evaluate the clinical effectiveness of an early intensive applied behaviour analysis-based intervention for autistic children. An economic analysis included a review of existing analyses and the development of a new model.

RESULTS

Twenty studies were included in the clinical review. Individual participant data were retrieved from 15 of these studies. Results favoured the interventions when assessing adaptive behaviour after 2 years compared with treatment as usual/eclectic interventions (mean difference 7.00, 95% confidence interval 1.95 to 12.06). In analyses of cognitive ability (intelligence quotient), results favoured the interventions by approximately 10 points after 1 year (mean difference 9.16, 95% confidence interval 4.38 to 13.93) and 2 years (mean difference 14.13, 95% confidence interval 9.16 to 19.10). Evidence for other outcomes was limited and meta-analyses were generally inconclusive. There was no evidence that the effect of the interventions varied with characteristics of the children, but data were limited. Adopting a £30,000 per quality-adjusted life-year threshold, the results of the cost-effectiveness analysis indicate that early intensive applied behaviour analysis-based interventions would need to generate larger benefits or cost savings to be cost-effective. Adopting a public sector perspective and making pessimistic assumptions about long-term effects, the incremental cost-effectiveness ratio for early intensive applied behaviour analysis-based therapy compared with treatment as usual is £189,122 per quality-adjusted life-year. When optimistic assumptions are made, the incremental cost-effectiveness ratio is £46,768 per quality-adjusted life-year. Scenario analyses indicated that these interventions can potentially be cost-effective if long-term improvements persist into adulthood, or if they have significant impact on educational placement. Care should be taken when interpreting these scenarios owing to the limited data.

LIMITATIONS

All included studies were at risk of bias, there was substantial heterogeneity and effects varied considerably across studies. The effect of intervention on autism symptom severity, language development and school placement remains uncertain because of the limited data. The long-term effects are unclear owing to a lack of follow-up data.

CONCLUSIONS

This review found limited evidence that early intensive applied behaviour analysis-based interventions may improve cognitive ability and adaptive behaviour, but the long-term impact of the interventions remains unknown. The economic analysis is constrained by the limited effectiveness evidence, but suggests that these interventions are unlikely to be cost-effective unless clear long-term benefits, or a substantial change in which schools children attend, can be identified.

FUTURE WORK

Further studies into the effectiveness of early intensive applied behaviour analysis-based interventions may be warranted if they include well-defined, alternative interventions as comparators and collect relevant outcomes. Consideration should be given to future studies that not only address whether or not early intensive applied behaviour analysis-based interventions are clinically effective, but also aim to identify which components of early intensive applied behaviour analysis-based interventions might drive effectiveness.

Systematic review: measurement properties of patient-reported outcome measures evaluated with childhood brain tumor survivors or other acquired brain injury

Background

Survivors of childhood brain tumors or other acquired brain injury (ABI) are at risk of poor health-related quality of life (HRQoL); its valid and reliable assessment is essential to evaluate the effect of their illness on their lives. The aim of this review was to critically appraise psychometric properties of patient-reported outcome measures (PROMs) of HRQoL for these children, to be able to make informed decisions about the most suitable PROM for use in clinical practice.

Methods

We searched MEDLINE, EMBASE, and PsycINFO for studies evaluating measurement properties of HRQoL PROMs in children treated for brain tumors or other ABI. Methodological quality of relevant studies was evaluated using the consensus-based standards for the selection of health status measurement instruments checklist.

Results

Eight papers reported measurement properties of 4 questionnaires: Health Utilities Index (HUI), PedsQL Core and Brain Tumor Modules, and Child and Family Follow-up Survey (CFFS). Only the CFFS had evidence of content and structural validity. It also demonstrated good internal consistency, whereas both PedsQL modules had conflicting evidence regarding this. Conflicting evidence regarding test-retest reliability was reported for the HUI and PedsQL Core Module only. Evidence of measurement error/precision was favorable for HUI and CFFS and absent for both PedsQL modules. All 4 PROMs had some evidence of construct validity/hypothesis testing but no evidence of responsiveness to change.

Conclusions

Valid and reliable assessment is essential to evaluate impact of ABI on young lives. However, measurement properties of PROMs evaluating HRQoL appropriate for this population require further evaluation, specifically construct validity, internal consistency, and responsiveness to change.

"Different but connected": Participatory action research using Photovoice to explore well-being in autistic young adults

LAY ABSTRACT

Past research has mainly focused on autistic people's deficits and poor outcomes compared to other groups of people. Little is known about their positive life experiences, and how to support them to achieve a higher quality of life. It is important to include autistic individuals in research so that they can influence how their voices are represented in a meaningful way and how the research results will be useful to them. In this study, a university researcher collaborated with 14 autistic young adults in a post-school transition program to design and run the research, collect and analyze the data, and use the results to create a presentation to the community. Specifically, the participants took photos in daily life and discussed their ideas about what a good life means to them. Results showed that these young adults described themselves as uniquely and different, but they were eager to learn and adapt. They also valued their relationships with their families, friends, and animals around them, as well as the community at large. This research shows that autistic individuals have important perspectives to share and knowledge to contribute when they are given the opportunities to participate in different aspects of research. The findings will be useful in developing services and influencing policies that promote well-being among autistic adults.

Discriminative and Criterion Validity of the Autism Spectrum Identity Scale (ASIS)

Individuals on the autism spectrum face stigma that can influence identity development. Previous research on the 22-item Autism Spectrum Identity Scale (ASIS) reported a four-factor structure with strong split-sample cross-validation and good internal consistency. This study reports the discriminative and criterion validity of the ASIS with other measures. Adults (n = 1139) who have, or identify with, an autism spectrum diagnosis took a nationally distributed online survey that also included demographic questions and measures for stigma, self-esteem, and quality of life (QoL). All four ASIS factors discriminated from measures of stigma and self-esteem. The ASIS also showed good criterion validity with the factors of Positive Difference and Changeability demonstrating widespread relationships with subjective quality of life in the expected directions.

Parent and Teacher Concordance of Child Outcomes for Youth with Autism Spectrum Disorder

Cross-informant ratings of are considered gold standard for child behavioral assessment. To date, little work has examined informant ratings of adaptive functioning for youth with autism spectrum disorder (ASD). In a large, diverse sample of youth with ASD, this study evaluated parent-teacher concordance of ratings of adaptive functioning and ASD-specific symptomatology across time. The impact of child clinical characteristics on concordance was also examined. Participants included 246 children, their caregivers and teachers. Parent-teacher concordance was variable but generally consistent across time. Concordance was significantly impacted by autism severity and child cognitive abilities. Findings inform the broader concordance literature and support the need to consider child clinical factors when assessing child functioning in samples of children with ASD.

Relating ASD symptoms to well-being: moving across different construct levels

BACKGROUND

Little is known about the specific factors that contribute to the well-being (WB) of individuals with autism spectrum disorder (ASD). A plausible hypothesis is that ASD symptomatology has a direct negative effect on WB. In the current study, the emerging tools of network analysis allow to explore the functional interdependencies between specific symptoms of ASD and domains of WB in a multivariate framework. We illustrate how studying both higher-order (total score) and lower-order (subscale) representations of ASD symptomatology can clarify the interrelations of factors relevant for domains of WB.

METHODS

We estimated network structures on three different construct levels for ASD symptomatology, as assessed with the Adult Social Behavior Questionnaire (item, subscale, total score), relating them to daily functioning (DF) and subjective WB in 323 adult individuals with clinically identified ASD (aged 17-70 years). For these networks, we assessed the importance of specific factors in the network structure.

RESULTS

When focusing on the highest representation level of ASD symptomatology (i.e. a total score), we found a negative connection between ASD symptom severity and domains of WB. However, zooming in on lower representation levels of ASD symptomatology revealed that this connection was mainly funnelled by ASD symptoms related to insistence on sameness and experiencing reduced contact and that those symptom scales, in turn, impact different domains of WB.

CONCLUSIONS

Zooming in across construct levels of ASD symptom severity into subscales of ASD symptoms can provide us with important insights into how specific domains of ASD symptoms relate to specific domains of DF and WB.

Transition of Individuals With Autism to Adulthood: A Review of Qualitative Studies

Many young adults with autism spectrum disorder experience poor transition outcomes in key areas, including postsecondary employment, higher education, health care, social connectedness, and independent living, yet we lack a clear understanding of the specific factors that impact these outcomes. We reviewed qualitative research in which the perspectives of youth and young adults with autism spectrum disorder, parents, services providers, and other stakeholders were gathered to identify barriers and facilitators to optimal outcomes. Findings revealed that poor transition outcomes are influenced by several factors, including poor person-environment fit, uncertainty about the roles of parents, and the lack of comprehensive or integrated services. These findings also revealed the aspects of familial, organizational, and policy contexts that may be targeted for interventions. Finally, stakeholders emphasized that supports should be individualized and focused on the changing aspects of the young adult's social and physical environment rather than behavior change. We discuss implications for policy and practice and provide recommendations for further research.

Measurement properties of instruments that assess participation in young people with autism spectrum disorder: a systematic review

AIM

To systematically review the measurement properties of instruments assessing participation in young people with autism spectrum disorder (ASD).

METHOD

A search was performed in MEDLINE, PsycINFO, and PubMed combining three constructs ('ASD', 'test of participation', 'measurement properties'). Results were restricted to articles including people aged 6 to 29 years. The 2539 identified articles were independently screened by two reviewers. For the included articles, data were extracted using standard forms and their risk of bias was assessed.

RESULTS

Nine studies (8 cross-sectional) met the inclusion criteria, providing information on seven different instruments. The total sample included 634 participants, with sex available for 600 (males=494; females=106) and age available for 570, with mean age for these participants 140.58 months (SD=9.11; range=36-624). Included instruments were the school function assessment, vocational index, children's assessment of participation and enjoyment/preferences for activities of children, experience sampling method, Pediatric Evaluation of Disability Inventory, Computer Adaptive Test, adolescent and young adult activity card sort, and Patient-Reported Outcomes Measurement Information System parent-proxy peer relationships. Seven studies assessed reliability and validity; good properties were reported for half of the instruments considered. Most studies (n=6) had high risk of bias. Overall the quality of the evidence for each tool was limited.

INTERPRETATION

Validation of these instruments, or others that comprehensively assess participation, is needed. Future studies should follow recommended methodological standards.

WHAT THIS PAPER ADDS

Seven instruments have been used to assess participation in young people with autism. One instrument, with excellent measurement properties in one study, does not comprehensively assess participation. Studies of three instruments that incorporate a more comprehensive assessment of participation have methodological limitations. Overall, limited evidence exists regarding measurement properties of participation assessments for young people with autism.

Child and Adult Factors Related to Quality of Life in Adults with Autism

The WHO Quality of Life-Brief questionnaire was used to assess quality of life (QoL) among 52 adults with autism (mean age 49 years) followed-up since childhood. Overall, assessments of QOL were more positive than measures of objective social outcome (jobs, independence, relationships etc.) but correlations between caregiver and self-reports were low. Informant ratings indicated few correlations between current QoL and any child or adult factors. On self-report ratings, QoL was significantly negatively correlated with severity of repetitive behaviours in childhood; higher QoL was positively associated with better adult social outcomes. However, only a minority of adults (n = 22) could provide self-report data and findings highlight the need to develop valid measures for assessing the well-being of adults with autism.

Parent-observed thematic data on quality of life in children with autism spectrum disorder

Domains of quality of life in children with autism spectrum disorder have not previously been explored and there has been no quality of life measure developed for this population. Our study investigated parent observations to identify the domains important to children with autism spectrum disorder who also had an intellectual disability. In all, 21 parents (19 mothers, 2 fathers) of children with autism spectrum disorder (aged 6–17 years) participated in a qualitative study to discuss their child’s quality of life. Thematic analysis using a grounded theory framework was conducted and 10 domains emerged in relation to health and well-being, capacity to perform and develop skills in daily life, and connections with the community and environment. Unique aspects of quality of life included varying levels of social desire, consistency of routines, and time spent in nature and the outdoors, which are not comprehensively captured in existing measures. Parent observations provide an initial framework for understanding quality of life in autism spectrum disorder and support the development of a new measure for this population.

Implementation of an Outcome Measure in Pediatric Behavioral Health: A Process Improvement Initiative

Introduction

Efforts to monitor outcomes in pediatric behavioral health are becoming a quality, financial, and regulatory imperative. The implementation of a broad-based measure to assess patient functioning at the start of pediatric psychology services, as well as at subsequent visits, has not been demonstrated. This article describes the systematic implementation of a measure of health-related quality of life (HRQOL) to assess functional impairment across an entire clinic population using quality improvement science and methodologies.

Methods

The Pediatric Quality of Life Inventory Generic Core 4.0 (PedsQL) was administered at initial and subsequent visits for all patients seeking treatment at a large, tertiary care pediatric psychology clinic in an academic pediatric medical center (Nationwide Children's Hospital, Columbus, Ohio). The goal of this project was to design a process change to support a 90% completion rate of this measurement tool by all clinicians.

Results

Within 16 months, the completion rate of the PedsQL increased from a baseline of 39% to the identified goal of 90%. This process change was within control limits (over 80%) for over 12 months.

Conclusion

This study demonstrates the implementation of a systematic process for collection of outcome measures in a pediatric behavioral health care setting. Successful administration of an outcome measure at multiple time points during the care of children and adolescents in a large psychology clinic can allow for quantitative assessment of treatment progress and identify a pathway for administration of additional measures.

A systematic review of quality of life of adults on the autism spectrum

Autism spectrum disorder is associated with co-existing conditions that may adversely affect an individual's quality of life. No systematic review of quality of life of adults on the autism spectrum has been conducted. Our objectives were as follows: (1) review the evidence about quality of life for adults on the autism spectrum; (2) critically appraise current practice in assessing quality of life of adults on the autism spectrum. We searched bibliographic databases and other literature to identify studies using a direct measure of quality of life of adults on the autism spectrum. Hand searching of reference lists, citation searching and personal communication with field experts were also undertaken. In total, 827 studies were identified; 14 were included. Only one quality of life measure designed for use with the general autism spectrum population was identified. Quality of life of adults on the autism spectrum is lower than that of typically developing adults, when measured with tools designed for the general population. There are no comprehensive autism spectrum disorder-specific quality of life measurement tools validated for use with representative samples of adults on the autism spectrum. There is a pressing need to develop robust measures of quality of life of autistic adults.

Quality of life of high-functioning children and youth with autism spectrum disorder and typically developing peers: Self- and proxy-reports

Studies have shown parents to report lower quality of life for their children with autism spectrum disorder than children's self-report scores and the same applies for data on typically developing children. Our objectives were to: (1) explore how high-functioning children with autism spectrum disorder rate their quality of life compared with paired controls without autism spectrum disorder; (2) explore how parents of high-functioning children with autism spectrum disorder rate their children's quality of life compared with parents of paired controls; and (3) compare child self-reports of quality of life with their parent's proxy-reports for both groups of children. Data were collected with the Icelandic self- and proxy-reported versions of the KIDSCREEN-27. Reports of 96 children with autism spectrum disorder, 211 controls and their parents were included in the analyses. Compared with controls, children with autism spectrum disorder had lower means on all quality of life dimensions. Parents of children with autism spectrum disorder evaluated their children's quality of life lower on all dimensions than did parents of controls. On four out of five dimensions, children with autism spectrum disorder reported better quality of life than did their parents. Despite differences in ratings children with autism spectrum disorder and their parents agreed on the most problematic dimensions, namely, social support and peers and physical well-being. Our results highlight the importance of seeking the viewpoints of both children and their parents.

Quality of Life for Transition-Age Youth with Autism or Intellectual Disability

We examined the subjective health and well-being of 389 transition-age youth with autism or intellectual disability using the parent proxy version of the KIDSCREEN-27. Parents reported well-being of youth with autism and youth with intellectual disability lower than a normative sample in the domains of Physical Well-being, Psychological Well-being, and Social Support and Peers. For both groups of young people, the lowest ratings were reported in Social Support and Peers. Higher ratings of well-being in one or more domains were predicted by minority status, youth character strengths, involvement in community activities, and religious faith. Challenging behaviors, autism, age, and speech as the primary mode of communication were predictive of lower ratings of well-being. We discuss implications for special educators and service providers and offer directions for future research.

Community participation and environment of children with and without autism spectrum disorder: parent perspectives

AIM

This study explored parent perspectives of participation patterns and environmental supports and barriers for high-functioning children with autism spectrum disorder (ASD) within their communities compared with a group of children without ASD.

METHOD

The Participation and Environment Measure for Children and Youth was used to gather online data from parents of 99 children with ASD and 241 children without ASD. Mann-Whitney U test and chi-square tests were used to explore differences between groups and Cohen's d was calculated to examine effect sizes.

RESULTS

Significant differences between children with and without ASD were observed for all participation and environment summary scores. Children with ASD participated less frequently, were less involved, and their parents were less satisfied with their child's participation in community-based activities. Parents of children with ASD also identified fewer supports for their child's participation and more environmental barriers than other parents.

CONCLUSION

Children with ASD participated less in community-related activities than children without ASD as perceived by their parents. Barriers limiting community participation included features of the social and physical environment and limited resources.

SIGNIFICANCE

Occupational therapists should focus on decreasing environmental challenges in their efforts to facilitate participation of children with ASD in the community.

Measurement properties of multidimensional patient-reported outcome measures in neurodisability: a systematic review of evaluation studies

AIM

To identify and appraise the quality of studies that primarily assessed the measurement properties of English language versions of multidimensional patient-reported outcome measures (PROMs) when evaluated with children with neurodisability, and to summarize this evidence.

METHOD

MEDLINE, Embase, PsycINFO, CINAHL, AMED, and the National Health Service Economic Evaluation Database were searched. The methodological quality of the papers was assessed using the COnsensus-based Standards for selection of health Measurement INstruments checklist. Evidence of content validity, construct validity, internal consistency, test-retest reliability, proxy reliability, responsiveness, and precision was extracted and judged against standardized reference criteria.

RESULTS

We identified 48 studies of mostly fair to good methodological quality: 37 papers for seven generic PROMs (CHIP, CHQ, CQoL, KIDSCREEN, PedsQL, SLSS, and YQOL), seven papers for two chronic-generic PROMs (DISABKIDS and Neuro-QOL), and four papers for three preference-based measures (HUI, EQ-5D-Y, and CHSCS-PS).

INTERPRETATION

On the basis of this appraisal, the DISABKIDS appears to have more supportive evidence in samples of children with neurodisability. The overall lack of evidence for responsiveness and measurement error is a concern when using these instruments to measure change, or to interpret the findings of studies in which these PROMs have been used to assess change.

Self-reported quality of life of young children with conditions from early infancy: a systematic review

CONTEXT

There is little consistency in the use of instruments for measuring self-reported quality of life (QoL) in young children.

OBJECTIVE

To systematically review studies of self-reported QoL in children aged <12 years with congenital health conditions, and to examine the agreement between self- and proxy-reports.

DATA SOURCES

Literature databases (MEDLINE, EMBASE, Web of Science, PsychINFO) were systematically searched, reference lists of eligible studies were scanned.

STUDY SELECTION

We included studies published in English between January 1989 and June 2013 which used validated instruments to assess self-reported QoL in children aged <12 years with a distinct congenital health condition identified in early infancy.

DATA EXTRACTION

We extracted data on study design, objective, sample characteristics, QoL assessment instrument, statistical techniques and results.

RESULTS

From 403 full-text articles assessed for eligibility, 50 studies underwent detailed review, and 37 were included in a narrative synthesis. Children's self-reported QoL was assessed by using a variety of generic and/or condition-specific instruments, with the Pediatric Quality of Life Inventory being the most frequently used (25% [9 studies]). Regardless of the condition or the instrument used, children often reported QoL similar to the reference population, except for lower scores in the physical functioning/health domain. There were differences between younger and older age groups according to QoL domain. The child's perception of QoL differed from that of his or her parents, in particular for subjective domains such as emotional functioning, and these differences were age related. The main limitation of the review resulted from the lack of published studies on self-reported QoL in young children, in particular, lacking both self-reports and proxy reports. Existing studies demonstrated wide variability in the QoL instruments used and approaches to statistical analyses, lack of information about the formation of the study sample (response rate; comparison of responders and nonresponders) and low sample sizes in the age group of interest.

CONCLUSIONS

The reviewed studies demonstrated that, even for younger children, both child and parent perspectives are essential to understanding the impact of a condition on a child's QoL.

Quality of life in children and adolescents with autism spectrum disorders: what is known about the effects of pharmacotherapy?

A diagnosis of autistic spectrum disorder (ASD), now estimated to affect one in 88 children, requires deficits in social communication and interactions, and restricted interests and/or repetitive behaviors. Almost all children with ASD have deficits in adaptive skills, many have intellectual disability, and others have co-occurring psychiatric disorders or symptoms. Thus, this complex disorder has shown to have a substantial impact on patients' quality of life (QoL) and that of their families. Medication treatment is considered by clinicians and families to address problems with functioning due to psychiatric problems, and, as such, one-third of children and adolescents with ASD take at least one psychotropic medication and many use complementary and alternative medicine. This paper reviews what is known about the benefits and risks of psychotropic medications on the QoL of children with ASD. Although scarce, there are studies of psychiatric medications in autistic patients that include QoL measures, such as the pediatric studies of aripiprazole for irritability and one adult study of oxytocin. The aripiprazole study showed a positive effect on QoL in treated patients, as did the oxytocin study. Several other psychotropic medications are used in the treatment of children with ASD, and although information is available on the risks and benefits of each, we do not have specific data on the QoL impact of these medications. The aripiprazole and oxytocin studies exemplify how researchers can include QoL measures and use this information to guide clinicians. Additionally, we will recommend areas of further study in pharmacotherapy and QoL research in the context of treating children with ASD.

Conceptualisation and development of a quality of life measure for parents of children with autism spectrum disorder

Parents of children with autism spectrum disorder (ASD) tend to experience greater psychological distress than parents of typically developing children or children with other disabilities. Quality of Life (QoL) is increasingly recognised as a critical outcome measure for planning and treatment purposes in ASD. There is a need for ASD-specific QoL measures as generic measures may not capture all relevant aspects of living with ASD. This paper describes the conceptualisation and development of an autism-specific measure of QoL, the Quality of Life in Autism Questionnaire (QoLA) for parents and caregivers of children with ASD, that is suitable to clinical and research settings. Preliminary psychometric properties (reliability and validity) of the measure are also presented. The QoLA has 48 items in two subscales: one comprising QoL items and the second a parent report of how problematic their child's ASD symptoms are. A study involving 39 families suggested the QoLA has excellent internal consistency as well as good known-groups validity between parents of children with ASD and those who were typically developing. The QoLA also showed good convergent validity with other measures of QoL and ASD symptom severity, respectively. The QoLA may be a valuable assessment tool and merits further psychometric evaluation.

Quality of life in autism across the lifespan: a meta-analysis

Autism is a lifelong neurodevelopmental disorder, with a known impact on quality of life. Yet the developmental trajectory of quality of life is not well understood. First, the effect of age on quality of life was studied with a meta-analysis. Our meta-analysis included 10 studies (published between 2004 and 2012) with a combined sample size of 486 people with autism and 17,776 controls. Second, as there were no studies on quality of life of the elderly with autism, we conducted an empirical study on quality of life of the elderly (age range 53-83) with autism (N = 24) and without autism (N = 24). The meta-analysis showed that quality of life is lower for people with autism compared to people without autism, and that the mean effect is large (Cohen's d = -0.96). Age did not have an effect on quality of life. The study concerning the elderly with autism showed that the difference in quality of life is similar in the elderly. Age, IQ and symptom severity did not predict quality of life in this sample. Across the lifespan, people with autism experience a much lower quality of life compared to people without autism. Hence, the quality of life seemed to be independent of someone's age.

Health-related quality of life in children with high-functioning autism

The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism ( n = 30) and peers ( n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves ( p < .001) or their parents ( p < .001), although disagreement (intra-class coefficient = −.075) between children and parental scores suggested variance in points of view. This study specifically investigated health-related quality of life in children with high-functioning autism as compared to a sample of peers, from the child’s perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child’s life that promote or hinder their sense of well-being.
