Mental health of adolescents: variations by borderline intellectual functioning and disability

Does disability modify the association between poor mental health and violence victimisation over adolescence? Evidence from the CoVAC cohort study in Uganda

We aimed to estimate the impact of poor mental health in early adolescence on subsequent poor mental health, depression, and violence victimisation in late adolescence and to determine whether young people living with disabilities experienced a stronger relationship between mental health and these outcomes. Data from two waves of a longitudinal cohort study of 2773 Ugandan adolescents were used to assess the impact of mental health difficulties in early adolescence (aged 11-14) on presence of subsequent mental health difficulties, depression and past year violence victimisation in later adolescence (aged 15-18). We used g-computation to examine how these outcomes changed dependent on levels of poor mental health in early adolescence and explored functional difficulties as an effect modifier. This study demonstrates high prevalence of mental health difficulties in adolescence. There is a positive association between mental health difficulties in early adolescence and experience of mental health difficulties, depression, and past year violence in later adolescence. The risk of poor outcomes is greater for individuals experiencing poorer mental health in early adolescence. The relationships between early mental health difficulties and both mental health difficulties in later adolescence and past year violence are stronger in young people with functional difficulties. Poor mental health in early adolescence is associated with depression and violence victimisation in later adolescence, and the association is stronger among adolescents living with disabilities. School-aged adolescents would benefit from violence prevention and mental health promotion interventions which are inclusive and engage and respond to the needs and rights of adolescents with disabilities.

Self-Harm Among 17-Year-Old Adolescents With/Without Disabilities in the United Kingdom

Background: Self-harm is a critical public health issue for adolescents/young adults. Aims: To estimate the prevalence of self-harm among adolescents with/without disabilities in the United Kingdom. Method: Secondary analysis of data collected at age 17 in the UK's Millennium Cohort Study. Results: Prevalence of self-harm was significantly greater among adolescents with disabilities for suicide attempts and six forms of self-harming behaviors. The lifetime prevalence of suicide attempts was 5.3% (4.5-6.3) among adolescents without disabilities, 21.9% (18.2-26.2) among adolescents with less limiting disabilities, and 25.5% (17.2-35.9) among adolescents with more limiting disabilities. Adjusted prevalence rate ratios ranged from 5.13 (3.58-7.36) for those with mental health limitations to 1.48 (0.65-3.35) for those with mobility limitations. Similar patterns were observed for the 12-month prevalence of six self-harming behaviors. Limitations: Further studies are needed to identify potential mediators of the association between disability and self-harm that are potentially modifiable. Conclusion: Adolescents with disabilities are at markedly greater probability of suicide attempts and self-harming behaviors than their peers.

Parental Report of Signs of Anxiety and Depression in Children and Adolescents with and Without Disability in Middle- and Low-Income Countries: Meta-analysis of 44 Nationally Representative Cross-Sectional Surveys

Population-based studies undertaken in high-income countries have indicated that children and adolescents with disabilities are more likely than their non-disabled peers to experience emotional difficulties such as anxiety and depression. Very little is known about the association between disability and emotional difficulties among children growing up in low and middle-income countries (LMICs). We aimed to estimate the strength of association between disability and two forms of emotional difficulties (anxiety, depression) in a range of LMICs and to determine whether the strength of this relationship was moderated by child age and gender. Secondary analysis of data collected in Round 6 of UNICEF's Multiple Indicator Cluster Surveys undertaken in 44 LMICs (combined n = 349,421). Data were aggregated across countries by both mixed effects multi-level modelling and restricted maximum likelihood meta-analysis. Young people with disabilities, when compared with their non-disabled peers, were approximately two and a half times more likely to be reported by parents to show daily signs of either anxiety or depression. The level of risk among young people with disabilities was highest in upper middle-income countries and lowest in low-income countries. We estimated that approximately 20% of young people with frequent anxiety or depression also had a disability. All approaches to mental health interventions (from primary prevention to clinical interventions) need to make reasonable accommodations to their services to ensure that the young people with emotional difficulties who also have a disability are not 'left behind'.

Suicidal ideation and intentional self-inflicted injury in autism spectrum disorder and intellectual disability: An examination of trends in youth emergency department visits in the United States from 2006 to 2014

LAY ABSTRACT

Youth suicide is a major problem in the United States and globally, but little is known about suicide risk in autistic youth and youth with intellectual disability specifically. Using data from the National Emergency Department Sample, which is the largest database of emergency department visits in the United States, we found that emergency department visits with a suicidal ideation or intentional self-inflicted injury diagnosis were more common in autistic youth and youth with intellectual disability than in youth without these diagnoses (i.e. the comparison group). This was true when examining both suicidal ideation diagnoses and intentional self-inflicted injury diagnoses at emergency department visits. In addition, the number of emergency department visits with a suicidal ideation or intentional self-inflicted injury diagnosis increased more from 2006 to 2014 in autistic youth and youth with intellectual disability compared with the comparison group. We also found both similarities and differences when examining factors, such as age, sex, and co-occurring mental health conditions, related to emergency department visits with a suicidal ideation or intentional self-inflicted injury diagnosis across groups that may be helpful for understanding suicide risk. It is urgent that we improve our understanding, assessment, and treatment of suicidality and self-harm in these groups through more research and clinical efforts.

Mental health problems in children with intellectual disability

Intellectual disability ranks in the top ten causes of disease burden globally and is the top cause in children younger than 5 years. 2-3% of children have an intellectual disability, and about 15% of children present with differences consistent with an intellectual disability (ie, global developmental delay and borderline intellectual functioning). In this Review, we discuss the prevalence of mental health problems, interventions to address these, and issues of access to treatment and services. Where possible, we take a global perspective, given most children with intellectual disability live in low-income and middle-income countries. Approximately 40% of children with intellectual disability present with a diagnosable mental disorder, a rate that is at least double that in children without intellectual disability. Most risk factors for poor mental health and barriers to accessing support are not unique to people with intellectual disability. With proportionate universalism as the guiding principle for reducing poor mental health at scale, we discuss four directions for addressing the mental health inequity in intellectual disability.

Below Average Cognitive Ability-An under Researched Risk Factor for Emotional-Behavioural Difficulties in Childhood

Children with below average cognitive ability represent a substantial yet under-researched population for whom cognitive and social demands, which increase in complexity year by year, may pose significant challenges. This observational study examines the longitudinal relationship between early cognitive ability and emotional-behavioral difficulties (EBDs) between the age of three and nine. Participants include 7134 children from the population-based cohort study growing up in Ireland. Cognitive ability was measured at age three using the Picture Similarities Scale. A t-score one to two standard deviations below the mean was defined as below average cognitive ability (n = 767). EBDs were measured using the Strengths and Difficulties Questionnaire (SDQ) at three, five, and nine years of age. Generalized linear mixed models and logistic regression were used to examine the relationship. Below average cognitive ability was an independent predictor of higher longitudinal SDQ scores. After adjustment, children with below average cognitive ability were 1.39 times more likely (AOR 1.39, 95% CI 1.17–1.66, p < 0.001) to experience a clinically significant EBD between the ages of three to nine years. This study demonstrates the increased risk of EBDs for children with below average cognitive ability. A scalable method of early identification of at-risk children should be a research priority for public health, enabling early intervention for cognitive and adaptive outcomes.

Dialectical behavior therapy-skills system for cognitively challenged individuals with self-harm: a Swedish pilot study

Background: Dialectical behavior therapy (DBT) is an evidence-based treatment for self-harm and emotion regulation difficulties. A modified version, DBT-Skills System (DBT-SS), has been developed in the USA for individuals with cognitive difficulties. The present study is a pilot study, testing the DBT-SS in a Swedish context. Methods: Six participants were treated with individual therapy and group skills training for 48 sessions each. A case series design was used to follow individual development over time. The primary outcome measure was reduction in challenging behaviors. Secondary outcomes were level of functioning in daily life, hospital admissions, and resilience and vulnerabilities in different risk domains. Data was analyzed using time-series diagrams. Effect sizes of changes were calculated using Cohen's d. Results: Challenging behaviors decreased over time and participants' global level of functioning increased. There was a reduction in number of hospital admissions over time. As for resilience and vulnerabilities, participants' overall level of risk in various areas remained unchanged or decreased after treatment. Conclusions: The results indicate that DBT-SS might be a promising treatment for cognitively challenged individuals with emotion regulation difficulties and challenging behaviors in a Swedish context. The study provides suggestions for a future randomized controlled trial. Supplemental data for this article is available online at here.

Borderline intellectual functioning

Borderline intellectual functioning (BIF), that is to say, tested IQ levels in the range of 70-84/85, is prevalent, affecting about 12%-14% of the population depending on the exact level for "diagnostic" cutoff. In the current Diagnostic and Statistical Manual of Mental Disorders, BIF does not have a separate diagnostic category but can be categorized with a V-code. Children and adolescents with BIF usually struggle both as regards school performance and in respect of social functioning. BIF is common in attention deficit hyperactivity disorder, but sometimes attention problems in schoolchildren with BIF may be a consequence of nonadapted academic demands. Autism and BIF may also coexist, and there are many cases of so-called high-functioning autism who are high functioning only in the sense that they do not meet criteria for intellectual disability, but function in the area of BIF. Currently, too little attention is given to the negative effects of BIF on child development and adaptation. Learning, academic, and behavioral problems and grade retention may be markers of BIF. Our diagnostic and classification manuals need to have specific categories that clarify the problems that BIF entails so that affected individuals can avail themselves of better educational support and understanding.

An intersectional approach to understandings of mental health inequalities among men with disability

Disability is a key social identity or social category that is associated with significant social disadvantage. For men, having a disability can be discordant with their masculine identity. Self-reliance is one component of masculinity that is known to be important to men with disabilities, however it is also known to be associated with adverse mental health outcomes in the broader adult male population. Intersectionality approaches offer a means of examining the way that the effect of self-reliance on mental health might vary between those with and without a disability. Among a sample of 12,052 men aged 18-55 years from the Ten-to-Men study, we used effect measure modification (EMM) to examine the way that self-reliance modifies the relationship between disability and depressive symptoms. Disability was assessed using the Washington Group Short Set of questions, which capture functional limitations. Results showed that men with disabilities who reported higher conformity to self-reliance norms had much worse mental health than non-disabled men with low conformity to self-reliance, as measured in terms of depressive symptoms (PRR: 9.40, 95%CI 7.88, 11.22, p-value<0.001). We found evidence of positive EMM of depressive symptoms by conformity to self-reliance on the additive scale (RERI: 2.84, 95%CI 1.26, 4.42, p-value<0.001). These results provide evidence that high conformity to self-reliance norms exerts a particularly damaging effect on the mental health of men with disabilities. Given that men with disabilities are more likely to rely on help and support from others, these results provide important insights for the delivery of services to men with disability.
