Mental health issues in children and adolescents with chronic illness

Friends' Perspective: Young Adults' Reaction to Disclosure of Chronic Illness

Chronic illness can negatively impact adolescents' and young adults' social support. Social support can buffer the negative impact of living with chronic illness. The purpose of this study was to test the acceptability of a hypothetical message to promote social support after a recent diagnosis of a chronic illness. Young adults (18-24; m = 21.30; N = 370), the majority of which were Caucasian, college-students, and female, were asked to read one of four vignettes and to imagine this situation happened while they were in high school. Each vignette contained a hypothetical message from a friend diagnosed with a chronic illness (cancer, traumatic brain injury, depression, or eating disorder). Participants answered forced-choice and free-response questions asking about the likelihood they would contact or visit the friend, and feelings about receiving the message. A general linear model was used to assess quantitative results, and qualitative responses were coded using the Delphi coding method. Participants responded positively, reporting a high likelihood to contact the friend, and feeling glad to receive the message regardless of vignette viewed; however, those who read the eating disorder vignette were significantly more likely to express discomfort. In qualitative responses, participants described positive emotions associated with the message and desire to support the friend. However, participants reported significantly greater discomfort with the eating disorder vignette. The results provide evidence for the potential of a short, standardized disclosure message to promote social support following chronic illness diagnosis with some additional considerations for those recently diagnosed with an eating disorder.

A randomized controlled clinical trial to improve health outcomes in youth with type 1 diabetes: Study design and baseline characteristics

Most adolescents with T1D do not meet glycemic recommendations or consistently perform the required self-management behaviors to prevent acute- and long-term deleterious health outcomes. In addition, most youth with T1D do not have access to behavioral health services to address T1D management barriers. Thus, delivering behavioral interventions during routine medical appointments may hold promise for improving T1D outcomes in adolescents. The overall objective of this study was to examine the effect of behavioral interventions, either a Personalized T1D Self-Management Behaviors Feedback Report or Problem-Solving Skills, delivered by a T1D behavioral health provider and a T1D medical provider during a joint, fully integrated appointment to improve health outcomes in youth with T1D. This paper describes the study rationale, design, and baseline characteristics for the 109 adolescent-caregiver dyads who participated. Primary and secondary outcomes include hemoglobin A1c (A1C), T1D self-management behaviors, and biological indicators of complications.

Psychiatric comorbidities in children and adolescents with chronic urticaria

BACKGROUND

Chronic urticaria (CU) has been shown to impact patients' quality of life negatively and may coexist with psychiatric disorders. We systematically reviewed the published evidence of comorbid psychiatric disorders in children and adolescents with CU.

METHODS

A systematic review of studies published until February 2022 in PubMed, Google Scholar, and Scopus was performed. An a priori set of inclusion criteria was predefined for the studies to be included: (1) clear distinction between urticaria and other allergies; (2) precise distinction between acute and CU; (3) participants younger than 18 years old, exclusively; (4) use of appropriate standardized questionnaires, psychometric tools, and standard diagnostic nomenclature for the mental health and behavioral disorders diagnosis; and (5) manuscripts written or published in the English language.

RESULTS

Our search identified 582 potentially relevant papers. Only eight of them satisfied the inclusion criteria. Quantitative meta-analysis was not deemed appropriate, given the lack of relevant randomized control trials, the small number of relevant shortlisted, the small sample size of the patients included in each study, and the remarkable heterogeneity of the studies' protocols.

CONCLUSIONS

The included studies suggest an increased incidence of psychopathology among children and adolescents with CU as opposed to healthy age-matched individuals, but the data are scarce. Further research is required to clarify whether psychopathology is just a comorbid entity, the cause, or the consequence of CU. Meanwhile an interdisciplinary collaboration between allergists/dermatologists and psychiatrists is expected to substantially minimize CU burden and improve patients' quality of life.

Mental Health and Health-Related Quality of Life in Austrian Adolescents with Chronic Physical Health Conditions: Results from the MHAT Study

Chronic physical health conditions (CPHC) are on the rise in younger age groups and might have a negative impact on children and adolescents. In a representative sample of Austrian adolescents aged 10-18 years, internalizing, externalizing, and behavioral problems were assessed cross-sectionally using the Youth Self-Report and health-related quality of life (HrQoL) using the KIDSCREEN questionnaire. Sociodemographic variables, life events, and chronic illness specific parameters were considered as associated variables with mental health problems in individuals with CPHC. Of 3469 adolescents, 9.4% of girls and 7.1% of boys suffered from a chronic pediatric illness. Of these individuals, 31.7% and 11.9% had clinically relevant levels of internalizing and externalizing mental health problems, respectively, compared to 16.3% and 7.1% adolescents without a CPHC. Anxiety, depression, and social problems were twice as high in this population. Medication intake due to CPHC and any traumatic life-event were related to mental health problems. All HrQoL domains were deteriorated in adolescents with a double burden of mental and CPHC, whereas adolescents with a CPHC without mental health problems did not differ significantly from adolescents without a chronic illness. Targeted prevention programs for adolescents with a CPHC are urgently needed to prevent mental health problems in the long term.

Rethinking mental wellness among adolescents: an integrative review protocol of mental health components

BACKGROUND

Adolescents have been overlooked in global public health initiatives as this period is generally considered to be the healthiest in an individual's life course. However, the growth of the global adolescent population and their changing health profiles have called attention to the diverse health needs of adolescents. The increased attention toward adolescent health has accentuated existing gaps as global health reports have emphasised that there is a continued need for valid and reliable health data. In this context, evidence has shown that mental health issues constitute one of the greatest burdens of disease for adolescents. This integrative review aims to unpack the meaning of mental wellness among adolescents and its associated constructs by analysing and synthesising empirical and theoretical research on adolescent mental wellness. In doing this, we will develop a working definition of adolescent mental wellness that can be used to develop an instrument aimed at measuring adolescent mental wellness.

METHODS

The integrative review is guided by the five steps described by Whittemore and Knafl. A comprehensive search strategy which will include carefully selected terms that correspond to the domains of interest (positive mental health/mental wellness) will be used to search for relevant literature on electronic databases, grey literature and government or non-governmental organisations (NGO) websites. Studies will be included if they describe and/or define general mental wellness in adolescent populations aged 10-19. The screening and reporting of the review will be conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data from the integrative review will be analysed using narrative framework synthesis for qualitative and quantitative studies.

DISCUSSION

This integrative review aims to search for and synthesise current research regarding adolescent mental wellness to identify how wellness is being described and conceptualised. We aim to identify gaps and to contribute to a more comprehensive definition of mental wellness which can aid in the development of an age- and culturally appropriate measure of adolescent mental wellness.

Digital health interventions for improving mental health outcomes and wellbeing for youth with type 1 diabetes: A systematic review

Digital health interventions are a promising alternative to face-to-face psychosocial interventions that may improve psychological outcomes in youth with diabetes. Several reviews have explored the efficacy of digital health interventions for adults and youth with some chronic health conditions; however, their efficacy among youth with type 1 diabetes is not known. This systematic review aims to assess digital health interventions targeting both psychological and physical health outcomes in youth with type 1 diabetes as well as to evaluate study quality and efficacy, and provide directions for future research in this area. Relevant studies were identified through searches conducted in MEDLINE, Embase, APA PsycInfo, Scopus, Cochrane Central, and CINAHL Plus up until February 2021. Studies were included if they were randomized; reported at least one psychological outcome that was assessed at ≥2 time points; included a digital health intervention; and were conducted in youth aged 5 to 25 years with type 1 diabetes. The revised Cochrane risk-of-bias (RoB 2) tool was used to assess risk of bias. Of the 5159 articles found, 15 met the inclusion criteria and were included in the review. Self-efficacy improved in 2 of the 3 studies which assessed self-efficacy; however, no consistent improvements were found for other psychological, behavioral, or physical outcomes. All studies showed some risk of bias concerns. More research is needed to make firm conclusions on the efficacy of digital health interventions for youth with diabetes. More specifically, interventions based on psychological theories are needed and studies of higher quality methodologies.

Leveraging electronic health records to inform genetic counseling practice surrounding psychiatric disorders

Since nearly one-fifth of US adults have a psychiatric disorder, genetic counselors (GCs) will see many patients with these indications. However, GCs' reports of inadequate preparation and low confidence in providing care for patients with psychiatric disorders can limit their ability to meet patient's needs. How frequently psychiatric disorders present in GC sessions is currently unclear. Here, we used deidentified electronic health records (EHR) to estimate the prevalence of 16 psychiatric disorders. In 7,155 GC patients, 34% had a diagnostic code associated with a psychiatric disorder; 23% with anxiety/phobic disorders; 21% with mood disorder/depression; 5% with attention deficit hyperactivity disorder (ADHD); and 1% with psychotic disorders. Compared to 415,709 demographically matched controls, GC patients showed a significantly higher prevalence of psychiatric disorders (GC prevalence: 34%, matched prevalence: 30%, p-value < 0.0001) driven predominantly by anxiety disorder, major depressive disorder, generalized anxiety disorder, and ADHD. Within GC specialties (prenatal: n = 2,674, cancer: n = 1,474, pediatric: n = 465), only pediatric GC patients showed a significant increase in psychiatric disorder prevalence overall (pediatric GC prevalence: 28%, matched prevalence: 13%, p-value < 0.0001). However, significant evidence of increased prevalence existed for generalized anxiety disorder (prenatal GC prevalence 6.4%, matched prevalence: 4.9%, p-value < 0.0001), anxiety disorders (cancer GC prevalence: 26%, matched prevalence: 21%, p-value < 0.0001 and pediatric GC prevalence: 12%, matched prevalence: 5.5%), and ADHD (pediatric GC prevalence: 18%, matched prevalence: 7.9%, p-value < 0.0001). These results highlight the need for additional guidance around care for patients with psychiatric disorders and the value of EHR-based research in genetic counseling.

Feasibility and potential efficacy of a guided internet- and mobile-based CBT for adolescents and young adults with chronic medical conditions and comorbid depression or anxiety symptoms (youthCOACHCD): a randomized controlled pilot trial

Background

Adolescents and young adults (AYA) with a chronic medical condition show an increased risk for developing mental comorbidities compared to their healthy peers. Internet- and mobile-based cognitive behavioral therapy (iCBT) might be a low-threshold treatment to support affected AYA. In this randomized controlled pilot trial, the feasibility and potential efficacy of youthCOACH_CD, an iCBT targeting symptoms of anxiety and depression in AYA with chronic medical conditions, was evaluated.

Methods

A total of 30 AYA (M_age 16.13; SD= 2.34; 73% female), aged 12-21 years either suffering from cystic fibrosis, juvenile idiopathic arthritis or type 1 diabetes, were randomly assigned to either a guided version of the iCBT youthCOACH_CD (IG, n=15) or to a waitlist control group (CG, n=15), receiving an unguided version of the iCBT six months post-randomization. Participants of the IG and the CG were assessed before (t0), twelve weeks after (t1) and six months after (t2) randomization. Primary outcome was the feasibility of the iCBT. Different parameters of feasibility e.g. acceptance, client satisfaction or potential side effects were evaluated. First indications of the possible efficacy with regard to the primary efficacy outcome, the Patient Health Questionnaire Anxiety and Depression Scale, and further outcome variables were evaluated using linear regression models, adjusting for baseline values.

Results

Regarding feasibility, intervention completion was 60%; intervention satisfaction (M = 25.42, SD = 5.85) and perceived therapeutic alliance (M = 2.83, SD = 1.25) were moderate and comparable to other iCBTs. No patterns emerged regarding subjective and objective negative side effects due to participation in youthCOACH_CD. Estimates of potential efficacy showed between group differences, with a potential medium-term benefit of youthCOACH_CD (β = -0.55, 95%CI: -1.17; 0.07), but probably not short-term (β = 0.20, 95%CI: -0.47; 0.88).

Conclusions

Our results point to the feasibility of youthCOACH_CD and the implementation of a future definitive randomized controlled trial addressing its effectiveness and cost-effectiveness. Due to the small sample size, conclusions are premature, however, further strategies to foster treatment adherence should be considered.

Trial registration

The trial was registered at the WHO International Clinical Trials Registry Platform via the German Clinical Trials Register (ID: DRKS00016714, 25/03/2019).

Measuring mental wellness among adolescents living with a physical chronic condition: a systematic review of the mental health and mental well-being instruments

Background

Globally, promoting mental health and well-being among adolescents has become a public health priority, especially for adolescents living with a physical chronic condition (CC), as research suggests they may be more at risk of developing mental health co-morbidities. Valid and reliable instruments are needed to measure and better understand mental health and mental well-being among adolescents living with a CC. To this end, we reviewed studies reporting on mental health and well-being instruments used in adolescent populations living with a chronic physical condition/disease globally.

Methods

We used a systematic review method guided by PRISMA to identify assess mental health and mental well-being instruments used in adolescents living with a CC. In this instance, mental health instruments were defined as those representing negative domains of mental health (i.e. depression and anxiety) while mental well-being instruments included positive aspects of mental health (i.e. self-concept and resilience).

Results

We identified 22 articles, which included 31 instruments that were used to measure either mental health (n = 8) or mental well-being (n = 15) or both (n = 8) in adolescents living with a CC. Of these, thirteen studies used a Health-Related Quality of Life (HRQoL) scale to measure mental health and/or mental well-being. The KIDSCREEN questionnaires and the Strengths and Difficulties Questionnaire were identified as being frequently used across the 22 studies. Additionally, 7 out of the 31 instruments were disease specific, with 3 focusing on adolescents with diabetes. All the instruments were developed in high income countries and adapted for use in lower- and middle-income countries (LMICs). Adolescents with Type 1 Diabetes (n = 7) and HIV (n = 4) were researched in 11 out of 22 studies. Only eight studies were conducted in LMIC, of which four were in Africa.

Conclusions

HRQoL instruments are useful in measuring mental health and well-being in adolescents living with a CC. However, relatively few valid measures of mental health and mental well-being for adolescents living with a CC exist, which accentuates the paucity of research on mental health and mental well-being of adolescents who are living with a CC. Specific measures need to be developed in and for LMICs where cultural contexts affect mental well-being in unique ways.

Discharged from paediatric intensive care: A mixed methods study of teenager's anxiety levels and experiences after paediatric intensive care unit discharge

BACKGROUND

Teenagers represent a small proportion of patients on paediatric intensive care units (PICU) in the United Kingdom. During a time when their development is rapidly changing, an admission to PICU causes additional disruption. The impact of critical illness on psychological health after discharge has not been widely reported within this population.

AIM AND OBJECTIVES

To measure anxiety that teenagers report 48-96 hours and 4 weeks after discharge from PICU. To explore teenagers' experiences of being admitted onto PICU.

DESIGN

Two-phase mixed methods, explanatory sequential design.

METHODS

This single-site study was conducted between February and July 2018. An NHS Ethics committee approved the study. Teenagers were screened if they were aged 13-18 years old and had an elective or emergency admission to PICU for longer than 24 hours. Hospital Anxiety and Depression Scale, Anxiety subscale (HADS-A) was administered on paper and completed with the researcher present. Semi-structured interviews were conducted in-person and over the telephone, audio-recorded and transcribed verbatim. Data were analysed using inductive thematic analysis.

RESULTS

Nine of eighteen participants (50%) obtained scores indicating levels of anxiety which were mild (n = 3; 17%), moderate (n = 2; 11%), or severe (n = 4; 22%) 48-96 hours after PICU discharge. Four weeks later, all participants scored below the clinically significant cut-off level for the HADS-A-1 Teenagers described their experiences on PICU within three themes: Memories of treatments, side effects, and the PICU environment Losing a sense of self Feeling cared for CONCLUSIONS: Measured levels of anxiety had resolved in this small sample, 4 weeks after PICU discharge. This finding was not consistent with qualitative data that indicated that many experiences shared by participants were anxiety provoking.

RELEVANCE TO CLINICAL PRACTICE

Support for teenagers after PICU discharge should be available to meet individual needs; screening teenagers to identify support needs would be beneficial.

Predictors of Depression and Anxiety Symptoms in Brazil during COVID-19

The COVID-19 pandemic in Brazil is extremely severe, and Brazil has the third-highest number of cases in the world. The goal of the study is to identify the prevalence rates and several predictors of depression and anxiety in Brazil during the initial outbreak of COVID-19. We surveyed 482 adults in 23 Brazilian states online on 9-22 May 2020, and found that 70.3% of the adults (n = 339) had depressive symptoms and 67.2% (n = 320) had anxiety symptoms. The results of multi-class logistic regression models revealed that females, younger adults, and those with fewer children had a higher likelihood of depression and anxiety symptoms; adults who worked as employees were more likely to have anxiety symptoms than those who were self-employed or unemployed; adults who spent more time browsing COVID-19 information online were more likely to have depression and anxiety symptoms. Our results provide preliminary evidence and early warning for psychiatrists and healthcare organizations to better identify and focus on the more vulnerable sub-populations in Brazil during the ongoing COVID-19 pandemic.

Comprehensive psychosocial screening in a pediatric diabetes clinic

OBJECTIVE

The ISPAD recommends routine, comprehensive psychosocial screening for adolescents with diabetes. However, few clinics have implemented procedures consistent with these guidelines. This study describes the results of a universal, comprehensive psychosocial screening program in an integrated pediatric diabetes clinic located within an academic medical center.

RESEARCH DESIGN AND METHODS

Participants included 232 ethnically diverse adolescents with type 1 diabetes (55.5% female; M age = 14.85; 58.5% Hispanic; 20% Black). Adolescents completed screening measures on iPads in the waiting room before their medical visit. The proportion of adolescents screening positive on each psychosocial measure was assessed, and regression analyses evaluated how psychosocial variables accounted for variance in insulin non-adherence and glycemic control (measured by A1c).

RESULTS

Psychosocial concerns were common and ranged from 7% of adolescents screening positive for disordered eating and suicide risk to 52% screening positive for low motivation to manage diabetes. A1c and insulin non-adherence were positively correlated with suicide risk, depressive symptoms, anxiety, disordered eating, diabetes stress, blood glucose monitoring stress, family conflict, and total number of elevations, and negatively correlated with intrinsic motivation. Insulin non-adherence, disordered eating, diabetes stress, and family conflict uniquely predicted A1c. Age, motivation, and family conflict uniquely predicted insulin non-adherence. Eighty-three percent of eligible youth completed the screener. Referrals by physicians to the team psychologist increased by 25% after the screening program was implemented.

CONCLUSIONS

Comprehensive psychosocial screening can be effectively implemented as part of routine pediatric diabetes care and can identify adolescents in need of additional supports.

Study protocol for You.Mind!: boosting first-line mental health care for YOUngsters suffering from chronic conditions with mindfulness: a randomised staggered within-subjects design

INTRODUCTION

Adolescents with chronic conditions often experience high levels of stress, anxiety and depression, and reduced quality of life. Mindfulness-based interventions (MBIs) have been found to improve emotional distress in clinical and non-clinical populations and are a promising technique to support adolescents with chronic conditions in managing their symptoms and ultimately enhance their quality of life.

METHODS AND ANALYSIS

To test the effects of an MBI on emotional distress and quality of life and delineate the underlying mechanisms, the You.Mind! study uses a randomised staggered within-subjects design. Thirty adolescents with a chronic condition will be randomised to a baseline phase of 14-28 days followed by an MBI, consisting of four online group sessions and online support spread over 8 weeks. Outcomes will be assessed by short, repeated measurements throughout the baseline, intervention and follow-up phases and by standardised questionnaires and experience sampling measures before randomisation, at postintervention and at 3-months follow-up. Analysis will be based on general linear modelling and multilevel mixed-effects modelling.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Ethics Committee Research UZ/KU Leuven and the Ethics Committee of Ghent University Hospital and Ghent University (S63485). Results will be disseminated through presentations at public lectures, scientific institutions and meetings, and through publication in peer-reviewed journals.

TRIAL REGISTRATION NUMBER

NCT04359563.

Prevalence of Depression and Anxiety in Adolescents With Hearing Loss

OBJECTIVE

To develop and implement a universal screening protocol for depression and anxiety in adolescents serviced in an otology and audiology practice and to estimate the prevalence of depression and anxiety in adolescents with hearing loss, while also comparing rates by degree of hearing loss and type of hearing device used.

STUDY DESIGN

Cross-sectional.

SETTING

University tertiary medical center.

PATIENTS

One hundred four adolescents 12- to 18-years-old who attended an otology clinic in a large metropolitan hospital in the southeastern United States.

MAIN OUTCOME MEASURE

(s): Depression (PHQ-8), anxiety (GAD-7), degree of hearing loss, type of hearing loss, and type of hearing device utilized.

RESULTS

Twenty-five percent of adolescents scored above the clinical cutoff on at least one of the depression and/or anxiety measures, with 10% scoring in the elevated range on both measures. Specifically, 17% scored above the cutoff on the PHQ-8 and 16% scored in the clinically significant range for the GAD-7. An additional 30 and 21% scored in the at-risk range for depression and anxiety, respectively. Older adolescents were more likely to score within the elevated range for depression (r = 0.232, p = 0.026). Also, adolescents with severe to profound hearing loss had higher rates of depression and anxiety.

CONCLUSIONS

Integration of mental health screening is needed in otology and audiology practices both to identify those who require psychological support and to provide appropriate treatment to reduce long-term impact of hearing loss on quality of life and mental health functioning in adolescents.

Involving patients' perspective in the development of an internet- and mobile-based CBT intervention for adolescents with chronic medical conditions: Findings from a qualitative study

OBJECTIVE

A user-centered approach is critical for increasing the adherence to and effectiveness of an internet- and mobile-based intervention program. Therefore, potential future intervention users were involved in the development of an internet- and mobile-based cognitive behavioral therapy program (iCBT) for adolescents and young adults (AYA) with chronic medical conditions and comorbid symptoms of anxiety or depression. We aimed to identify challenges and coping strategies of the intended target group, as well as their needs and preferred intervention characteristics for an iCBT program.

METHODS

Twenty AYA (aged 14-20, 60% females) with either type 1 diabetes (55%), juvenile idiopathic arthritis (25%) or cystic fibrosis (20%) were interviewed in condition-specific focus groups (4-11 participants per group) either via videoconferencing or face-to-face. Transcript verbatim data was analyzed using content analysis.

RESULTS

Frequently reported disease-specific burdens were among others fear of disease progression, non-acceptance of disease and stressful incidents related to and aversions against medical therapy. Most frequently reported coping strategies included, seeking social support and accepting the disease. Recommendations for the content of an iCBT for comorbid symptoms of anxiety and depression comprised: dealing with disease-related fears and getting advice on health-promoting lifestyles. iCBT characteristics considered preferable by participants were: providing individual feedback by a real-person; implementation of a feature to monitor treatment progress; youthful and varied content presentation; time per session not exceeding 1 h; non-involvement of parents. A mobile-based reminder feature was considered useful, and individual tailoring and self-determination of iCBT content was considered desirable.

CONCLUSIONS

The findings highlight important patient perspectives and age-specific recommendations which can help design more optimal iCBT interventions for AYA with chronic medical conditions.

Secondary School Pupils' Mental Wellbeing Is Associated with Belonging to a Perceived Minority and Experiencing Discrimination

Adolescents' mental health is a global issue and there is a growing interest in tackling mental health in schools. The study aimed to assess secondary school pupils' mental wellbeing and the factors related to their mental wellbeing (sociodemographic characteristics, perception of belonging to a minority, and discrimination). Data were collected from 12-17-year-old pupils of a Finnish secondary school via an online questionnaire. Data were analyzed with descriptive statistics and ANOVA for group comparisons. Participants' (Ν = 114) mental wellbeing scores were above average (47.5, max. 70). Worse family relations were independently associated with worse mental wellbeing. Additionally, significantly lower scores on mental wellbeing were found among pupils who thought they belonged to a minority due to appearance, sexual orientation, and/or chronic disease. Participants who had experienced discrimination had significantly lower mental wellbeing scores in comparison to those who never had such an experience. In conclusion, mental health promotion interventions which promote good family relations should be targeting different youth groups in order to address their specific needs. Thus, screening programs which identify pupils who are at risk or belong to minority groups are needed, in order to direct them to proper services when needed and/or implement mental health promotion interventions accordingly.

Adolescent mental wellness: a systematic review protocol of instruments measuring general mental health and well-being

INTRODUCTION

The promotion of mental health well-being among global adolescent populations is of great public health and social significance. This is particularly true for adolescents living with chronic illnesses as studies have shown that these populations are at higher risk for developing mental health problems. There is vast recognition of the need for age and culturally appropriate interventions to promote mental well-being and prevent mental health problems. In stark contrast, there is a dearth of relevant measures of mental well-being for adolescents. Our proposed systematic review aims to identify measures of mental well-being and to assess content, psychometric properties and relevance to adolescent populations.

METHODS AND ANALYSIS

The systematic review methodology will be guided by the seven steps proposed by Eggar, Davey and Smith. Documents will be sourced from electronic databases (Academic Search Complete, Educational Resource Information Center, Medical Literature Analysis Retrieval System Online, Cumulative Index of Nursing and Allied Health Literature plus, PsyArticles, SocIndex and Sabinet). All documents will be exported to Mendeley and two reviewers will independently screen the titles, abstracts and full texts for inclusion. Any discrepancies will be resolved by a third party. We will include studies published in all languages from 2000 to 2020, that use an instrument(s) that measure mental well-being among adolescent populations. Studies reporting on clinically significant mental illnesses or disorders will be excluded. A descriptive meta-synthesis approach will be used to identify and describe the mental health instruments used among adolescent populations, and to report on the psychometric properties.

ETHICS AND DISSEMINATION

Ethical approval is not required. The results of this review will be disseminated through a peer-reviewed publication as well as conference presentations.

To what extent is the association between disability and mental health in adolescents mediated by bullying? A causal mediation analysis

Background

Disability among adolescents is associated with both poorer mental health (MH) and higher levels of bullying-victimization. Bullying, therefore, conceivably mediates the association between disability and MH. Quantifying this pathway is challenging as the exposure (disability), mediator (bullying) and outcome (MH) are subjective, and subject to dependent measurement error if the same respondent reports on two or more variables.

Methods

Utilizing the counterfactual and potential outcomes approaches to causal mediation, we decomposed the total effect of disability on MH into natural indirect effects (through bullying) and natural direct effects (not through bullying) using a sample of 3409 adolescents. As the study included data from multiple informants (teacher, parent, adolescent) on the outcome (MH, as measured on the Strengths and Difficulties Questionnaire) and two informants (adolescent, parent) on the mediator (bullying), we assessed the influence of dependent measurement error.

Results

For preferred analysis (using parent-reported bullying and adolescent-reported MH), the total effect was a 2.18 [95% confidence interval (CI): 0.66-3.40] lower MH score for adolescents with a disability, compared with those with no disability (strength of association equivalent to 37% of the standard deviation for MH). Bullying explained 46% of the total effect. Use of adolescent-reported bullying with adolescent-reported MH produced similar results (37% mediation, 95% CI: 12-74%).

Conclusions

Disability exerts a detrimental effect on adolescent MH, and a large proportion of this appears to operate through bullying. This finding does not appear to be spurious due to dependent measurement error.
