Sex-Specific Distributed White Matter Microarchitectural Alterations in Preadolescent Youths With Anxiety Disorders: A Mega-Analytic Study.

Anxiety disorders are among the most common psychiatric disorders in youths and emerge during childhood. This is also a period of rapid white matter (WM) development, which is critical for efficient neuronal communication. Previous work in preadolescent children with anxiety disorders demonstrated anxiety disorder-related reductions in WM microstructural integrity (fractional anisotropy [FA]) in the uncinate fasciculus (UF), the major WM tract facilitating prefrontal cortical-limbic structural connectivity. Importantly, this association was found only in boys with anxiety disorders. To confirm this finding and more comprehensively understand WM changes in childhood anxiety, this mega-analytic study characterizes WM alterations related to anxiety disorders and sex in the largest sample of preadolescent children to date. Diffusion tensor imaging data from published studies of preadolescent children with anxiety disorders and healthy volunteers (ages 8-12) (N=198) were combined with a new data set (N=97) for a total sample of 165 children with anxiety disorders and 132 healthy volunteers. Children with anxiety disorders met DSM-5 criteria for current generalized, separation, and/or social anxiety disorder. Analyses of tractography and voxel-wise data assessed between-group differences (anxiety disorder vs. healthy volunteer), effects of sex, and their interaction. Tract-based and voxel-wise analyses confirmed a significant reduction in UF FA in boys but not girls with anxiety disorders. Results also demonstrated other significant widespread anxiety disorder-related WM alterations specifically in boys, including in multiple commissural, association, projection, and brainstem regions. In addition to confirming male-specific anxiety disorder-related reductions in UF FA, the results demonstrate that anxiety disorders in boys and not girls are associated with broadly distributed WM alterations across the brain. These findings support further studies focused on understanding the extent to which WM alterations in boys with anxiety disorders are involved in pathophysiological processes that mediate anxiety disorders. The findings also suggest the possibility that WM microarchitecture could serve as a novel treatment target for childhood anxiety disorders.

Interactions between genetic risk for 21 neurodevelopmental and psychiatric disorders and sport activity on youth mental health

Childhood is a sensitive period where behavioral disturbances, determined by genetics and environmental factors including sport activity, may emerge and impact risk of mental illness in adulthood. We aimed to determine if participation in sports can mitigate genetic risk for neurodevelopmental and psychiatric disorders in youth. We analyzed 4975 unrelated European youth (ages 9–10) from the Adolescent Brain Cognitive Development Study. Our outcomes were eight Child Behavior Checklist (CBCL) scores, measured annually. Polygenic risk scores (PRSs) were calculated for 21 disorders, and sport frequency and type were summarized. PRSs and sport variables were tested for main effects and interactions against CBCL outcomes using linear models. Cross-sectionally, PRSs for attention-deficit/hyperactivity disorder and major depressive disorder were associated with increases in multiple CBCL outcomes. Participation in non-contact or team sports, as well as more frequent sport participation reduced all cross-sectional CBCL outcomes, whereas involvement in contact sports increased attention problems and rule-breaking behavior. Interactions revealed that more frequent exercise was significantly associated with less rule breaking behavior in individuals with high genetic risk for obsessive compulsive disorder. Associations with longitudinal CBCL outcomes demonstrated weaker effects. We highlight the importance of genetic context when considering sports as an intervention for early life behavioural problems.

Long-term psychiatric outcomes in youth with enterovirus A71 central nervous system involvement

Long-term neurological and neurodevelopmental sequelae are a concerning issue for people with Enterovirus A71 (EV-A71) central nervous system (CNS) infection. Unfortunately, no longitudinal prospective clinical study has systematically investigated the consequences of EV-A71 CNS infection during early life on the later development of other psychiatric disorders. In this naturalistic longitudinal follow-up design, we followed forty-three youth, who got EV-A71 CNS involvement 6–18 years ago and were enrolled in other EV-A71 clinical studies then. Their psychiatric presentation, emotional/behavioral problems, and cognitive issues were examined using a psychiatrist-conducted diagnostic interview, parent- and self-rated questionnaires, and neuropsychological tests, respectively. We compared the prevalence of psychiatric disorders in youth with EV-A71 CNS involvement to a nationally representative cohort. Emotion/behavior and cognition in EV-A71-CNS-infected youth were compared to those in a matched community-based sample of healthy controls and youth with attention-deficit/hyperactivity disorder (ADHD). Compared to a national sample (absolute ADHD prevalence 10.1%), youth with EV-A71 CNS involvement had three times the odds of receiving an ADHD diagnosis (standardized prevalence ratio, 95% CI = 1.8, 4.2; absolute ADHD prevalence 34.9%). No other psychiatric diagnoses were more common in EV-A71-CNS-infected youth. Compared to community-based ADHD youth, EV-A71-CNS-infected youth with psychiatric disorders showed comparable core ADHD symptoms, opposition/defiance, autistic features, and suboptimal sustained attention performance (based on the Conners’ Continuous Performance Test), all of which were more severe than healthy controls. EV-A71-CNS-infected youth without psychiatric disorders showed comparable autistic features to EV-A71-CNS-infected youth with psychiatric disorders and ADHD youth. EV-A71 CNS involvement may cause long-term, adverse psychiatric outcomes that develop into an ADHD diagnosis alongside social/communication/emotion problems and autistic features. We recommend earlier identification and intervention of these problems among these children.

Commentary to "Translational machine learning for child and adolescent psychiatry".

In this commentary on 'Translational Machine Learning for Child and Adolescent Psychiatry,' by Dwyer and Koutsouleris, we summarize some of the main points made by the authors, which highlight the importance of emerging applications of machine learning for psychiatric disorders in youth but also emphasize principles of good practice. We also offer complementary insights regarding large-scale training, harmonization, and the ability of these artificial intelligence models to adapt to new datasets, which is critical for their stability across imaging centers, and hence for their widespread clinical adoption.

Development and feasibility testing of a physical activity intervention for youth with anxiety and depression: a study protocol

BackgroundAnxiety and depressive disorders in children and adolescents are highly prevalent and account for more than half of all youth psychiatric disorders. Left untreated, anxiety, and depression lead to numerous detrimental outcomes, including reduced quality of life, psychiatric, and somatic comorbidity and even reduced lifespan. This puts a large strain on child and adolescent mental healthcare services (CAMHS) to provide effective treatments. However, even when provided the best evidence-based treatment, between 40–50% of patients continue to report significant symptom burdens. Thus, there is an immediate need for supplemental and/or new treatment approaches. Physical activity as a supplementary treatment may be such an approach. However, research investigating this approach within this population is scant. This protocol paper describes the development and feasibility trial of a physical activity-based intervention targeting anxiety and depressive symptoms in youth treated in CAMHS.Methods/designThe study is based on the UK Medical Council Research Framework (MRC) for developing and evaluating complex interventions. Feasibility and acceptability of the physical activity intervention (confident, active, and happy youth) will be evaluated in an uncontrolled open-label trial using qualitative and quantitative data. Twenty youths with anxiety and/or depressive symptoms will be recruited. Acceptability of assessment procedures, the intervention, and perceived benefits and barriers to participation will be assessed, and qualitative interviews with participants, caregivers, and referring specialists will explore contextual and practical factors associated with intervention delivery. Physical activity will be measured using the Actigraph GT3X+ monitor at baseline, and post-intervention and change in anxiety and depression will be assessed.DiscussionThis study will contribute to the development of supplementary physical treatment interventions for youth with anxiety and depression in contact with CAMHS. The goal is to examine new avenues of treatment that ultimately may improve upon current treatment outcomes of anxiety and depression. This work will be in preparation for a future definitive randomized controlled trial (RCT) of this approach, in line with the MRC Framework.Trial registrationClnicalTrials.gov, NCT05049759.

What can a national patient registry tell us about psychiatric disorders and reasons for referral to outpatient services in youth with hearing loss?

Background Studies of reasons for referral to the Child and Adolescent Mental Health Services (CAMHS) and subsequent psychiatric disorders are missing in youth with Hearing loss (HL). Aims To examine the referral reasons to CAMHS and the clinically diagnosed psychiatric disorders in youth with HL among the nationally representative population. Methods The study population was a youth with HL referred to CAMHS and registered in the national Norwegian Patient Registry (NPR) during the years 2011–2016. The results were also compared with some data published from CAMHS for the General Youth Population (GenPop). Results Among youth with HL, 18.1% had also been referred to CAMHS compared to about 5% in GenPop, at mean age 9.1 years, >70% before age 13 years vs. 46% in the GenPop. Boys with HL comprised 57% and were referred about two years earlier than girls with HL. Compared to the GenPop, youth with HL were referred more frequently for suspected neurodevelopmental- and disruptive disorders, and less frequently for suspected emotional disorders. Girls with HL were referred for suspected Attention-Deficit/Hyperactivity Disorder (ADHD) at about the same rate as boys with HL in the 7–12 year age group. The most frequently registered psychiatric disorders were ADHD: 29.8%, anxiety disorders: 20.4%, and autism spectrum disorders: 11.0%, while disruptive disorders constituted about 5.0%. Conclusions Youth with HL were referred to CAMHS more often, but earlier than the GenPop, mostly due to ADHD disorders. Although more rarely referred for suspected anxiety disorders, these were frequently diagnosed, suggesting that anxiety was not recognized at referral in youth with HL.

Marijuana Legalization in Colorado: Increasing Potency, Changing Risk Perceptions, and Emerging Public Health Concerns for Youth.

Marijuana legalization occurred gradually in Colorado through political processes. This review aimed at describing the history of marijuana legalization and correlated shifts in product availability, use patterns, and risk perceptions and describes associated emerging concerns with this process for adolescents and young adults. This review focuses on the history of marijuana legalization and correlated shifts in product availability, use patterns, and risk perceptions. Along with the legalization of marijuana, there has been strong commercialization characterized by the widespread development of dispensaries, new products including edibles and concentrates, and an overall lowering of the "price per serving" of marijuana. While the frequency of marijuana use among adolescents does not appear to have shifted substantially, young adult patterns of use have demonstrated an increase in usage. A substantial shift has occurred in the increasing use of concentrates and high potency products. Emerging concerns related to high potency products include increased acute care visits, prevalence and outcomes of comorbid mental health disorders, cannabis-induced psychosis, driving while high, marijuana-related lung injuries, and increased use during pregnancy. Yet, there are also potential medical uses of marijuana. To date, scientific evidence of the mental or physical effects of high potency products is currently very limited. Clinical issues related to the treatment of marijuana use and comorbid psychiatric disorders in youth are discussed with a focus on how low risk perceptions influence treatment considerations.

Relations among co-occurring psychopathology in youth with autism spectrum disorder, family resilience, and caregiver coping

BackgroundCo-occurring mental health problems are common in youth with autism spectrum disorder (ASD) and are associated with greater caregiver stress; however, it is not known whether such challenges overwhelm caregivers’ ability to cope. Research has demonstrated that families of children with ASD are able to demonstrate resilience; yet, whether family resilience functions as a compensatory or protective factor in ASD families has not been investigated. This study aimed to examine the relations among family resilience, co-occurring psychopathology in youth with ASD, and caregiver coping. MethodData from this study were obtained from the 2016–2018 National Survey of Children’s Health (NSCH). Multiple binary logistic regression was run to examine the associations among commonly co-occurring psychiatric disorders in youth with ASD (i.e., anxiety, depression, attention-deficit/hyperactivity disorder, and behavioral/conduct problems) and caregiver coping. Another multiple binary logistic regression was run to examine whether family resilience moderates the aforementioned relationships. ResultsYouth with ASD and co-occurring conduct problems or depression were significantly more likely to be cared for by adults who were not coping well. High family resilience was directly associated with lower odds of poor parental coping; nonetheless, co-occurring conduct problems and depression were still associated with worse coping of caregivers after accounting for family resilience. ConclusionsFindings indicate that co-occurring depression and conduct problems in ASD youth may overwhelm their caregivers’ coping resources. Results also suggest that interventions targeting family resilience may improve the coping of adults caring for children and adolescents with ASD.

Childhood behaviours and adverse economic and social outcomes – can we improve detection and prevention?

IntroductionDisruptive behaviours underpin the most prevalent and costly psychiatric disorders in youth including ADHD and conduct disorder. Yet the association between childhood behavioural problems and economic and social outcomes in adulthood are rarely examined in a population-based samples where early detection and prevention may be possible.ObjectivesTo examine the association childhood behavioural problems and economic and social outcomes from age 18-35 years across three studies.MethodsThis study daws on 30-year Canadian birth cohort (n=3017) linked to government tax return records. Behavioural assessments – for inattention, hyperactivity, opposition, aggression, anxiety and prosociality – were prospectively obtained from teachers when children were aged 6-12 years. Regression models were used to link behavioural assessments in kindergarten (age 5/6 years) to earnings at age 33-35 years (Study 1) and to trajectories of welfare receipt (Study 2), while behaviour at age 10-12 years was linked to trajectories of partnering. Children’s IQ and family background were adjusted for.ResultsInattention, aggression-opposition (males only) and low low-prosociality in kindergarten were associated with lower earnings at age 33-35 years (Study 1), inattention, aggression-opposition and low prosociality in kindergarten predicted following a chronic welfare receipt trajectory from age 18-35 (Study 2), and inattention, aggression-opposition, anxiety and low-prosociality at age 10-12 years were associated with increased likelihood of being unpartnered and with partnership dissolution from age 18-35 years (Study3).ConclusionsBehavioural assessments made by schoolteachers can identify children at risk of adverse economic and social outcomes in adulthood. The implications of for early screening and prevention will be discussed.DisclosureNo significant relationships.

40.1 Psychiatric Disorders in Youth Exposed to Trauma: Complexity and Synergy

The prevalence of childhood trauma and adversity is such that it is unfortunately “not outside the realm of usual human experience,” necessitating the removal of this specific phrase from what was the previous criterion A of PTSD in the DSM-III-R. Child trauma and adversity can often occur via multiple trauma types and of varying chronicity. Children who have presented with some of the most complex forms of mental illness had chronic interpersonal trauma exposures (eg, child abuse, domestic violence, community violence, refugees of war). These exposures are such that their normal development is disrupted by traumatic stress, neurobehavioral issues, and functional problems that lead to significant psychiatric morbidity.

Linking molar organizational climate and strategic implementation climate to clinicians\u2019 use of evidence-based psychotherapy techniques: cross-sectional and lagged analyses from a 2-year observational study

BackgroundBehavioral health organizations are characterized by multiple organizational climates, including molar climate, which encompasses clinicians’ shared perceptions of how the work environment impacts their personal well-being, and strategic implementation climate, which includes clinicians’ shared perceptions of the extent to which evidence-based practice implementation is expected, supported, and rewarded by the organization. Theory suggests these climates have joint, cross-level effects on clinicians’ implementation of evidence-based practice and that these effects may be long term (i.e., up to 2 years); however, no empirical studies have tested these relationships. We hypothesize that molar climate moderates implementation climate’s concurrent and long-term relationships with clinicians’ use of evidence-based practice such that strategic implementation climate will have its most positive effects when it is accompanied by a positive molar climate.MethodsHypotheses were tested using data collected from 235 clinicians in 20 behavioral health organizations. At baseline, clinicians reported on molar climate and implementation climate. At baseline and at a 2-year follow-up, all clinicians who were present in the organizations reported on their use of cognitive-behavioral psychotherapy techniques, an evidence-based practice for youth psychiatric disorders. Two-level mixed-effects regression models tested whether baseline molar climate and implementation climate interacted in predicting clinicians’ evidence-based practice use at baseline and at 2-year follow-up.ResultsIn organizations with more positive molar climates at baseline, higher levels of implementation climate predicted increased evidence-based practice use among clinicians who were present at baseline and among clinicians who were present in the organizations at 2-year follow-up; however, in organizations with less positive molar climates, implementation climate was not related to clinicians’ use of evidence-based practice at either time point.ConclusionsOptimizing clinicians’ implementation of evidence-based practice in behavioral health requires attention to both molar climate and strategic implementation climate. Strategies that focus exclusively on implementation climate may not be effective levers for behavior change if the organization does not also engender a positive molar climate. These findings have implications for the development of implementation theory and effective implementation strategies.

Epidemiological study of child and adolescent psychiatric disorders in Lithuania

BackgroundFrom the public health perspective, epidemiological data of child mental health and psychosocial correlates were necessary and very lacking in Lithuanian society that has been undergoing rapid socio-economic change since the past decades. Together with determining the prevalence rates of disorders and assessing the needs for the services, this study has also shifted attention from the highly selective samples of children attending children and adolescent mental health services towards less severe cases of psychopathology as well as different attitudes of parents and teachers. The aim of the first epidemiological study in Lithuania was to identify the prevalence of psychiatric disorders in the community sample of children.MethodsChild psychiatric disorders were investigated in a representative sample of 3309 children aged 7–16 years (1162 7–10-year-olds and 2147 11–16-year-olds), using a two-phase design with the Lithuanian version of the Strengths and Difficulties Questionnaire (SDQ) in the first screening phase, and the Development and Well-Being Assessment (DAWBA) in the second diagnostic phase.ResultsThe estimated point prevalence of ICD-10 psychiatric disorders was 13.1% for the total sample (14.0% for the child sample and 12.1% for adolescent sample). The most common groups of disorders were Conduct disorders 6.6% (7.1% for child sample and 6.0% for adolescent sample), Anxiety disorders 5.0% (5.9% for child sample and 6.0% for adolescent sample), with Hyperkinesis being less common 2.0% (2.7% for child sample and 1.2% for adolescent sample). Potential risk factors were related to individual characteristics of the child (gender, poor general health, and stressful life experiences), and the family (single parenthood, foster care, unfavourable family climate, disciplining difficulties, worries related to TV or computer use).ConclusionsThe overall prevalence of youth psychiatric disorders was relatively high in this representative Lithuanian sample compared to Western European countries. The SDQ and DAWBA measures appear useful for the further research and clinical practice in this society.

Fine motor ability and psychiatric disorders in youth.

Impaired fine motor ability has been linked to several domains of psychopathology. However, studies validating the specificity of this association among several categorical psychiatric disorders are still needed. The aim of this study was to assess differences in fine motor ability performance among four non-overlapping groups of psychiatric disorders and a group of typical developing comparisons (TDC). Our sample consisted of 2035 subjects aged 6-14-year-old. Diagnoses of psychiatric disorders were performed with the Development and Well-Being Assessment (DAWBA). Five non-overlapping groups without comorbidity were formed: phobic disorders (n=101), distress disorders (n=82), attention deficit hyperactivity disorder (ADHD) (n=133), oppositional defiant disorder/conduct disorder (ODD/CD) (n=52) and one group of typical developing comparisons (TDC) (n=1667). Fine motor ability was evaluated by three tasks: sequential finger-thumb opposition, Oseretsky, and pronation/supination tests. Each task was assessed by total time to perform the movement and levels of accuracy, fluency, symmetry, precision, and coordination. We found that, when compared to TDC, the ADHD group performed more poorly in total fine motor ability (mean difference=-0.28; p=0.014), time to complete the task (mean difference=0.36; p<0.001), accuracy (mean difference=-0.30; p=0.005), fluency (mean difference=-0.26; p=0.03), symmetry (mean difference -0.25; p=0.04), precision (mean difference=-0.26; p=0.026), and coordination (mean difference=-0.25; p=0.042). The ADHD group also took more time to complete the task than the ODD/CD group (mean difference=0.45; p=0.037). No other significant between-group differences were found. Additional analyses showed those differences were statistically significant for all ADHD dimensions. Our results suggest that children with ADHD present impairments in all aspects of fine motor abilities compared to TDC, a difference not found in other psychiatric disorders.

Therapist-guided internet-delivered cognitive–behavioural therapy supplemented with group exposure sessions for adolescents with social anxiety disorder: a feasibility trial

ObjectivesSocial anxiety disorder (SAD) is one of the most common psychiatric disorders in youth, with a prevalence of about 3%–4% and increased risk of adverse long-term outcomes, such as depression....

Hallucinations Can Be Marker For Variety of Psychiatric Disorders in Youth

Understanding the experience of hallucinations among children and adolescents can help clinicians and researchers better understand the trajectory of individuals deemed to be at risk.

Prevalence and treatment of psychiatric disorders other than psychosis in children and adolescents with 22q11DS: Examining associations with social and role functioning

Individuals with chromosome 22q11 deletion syndrome (22q11DS) have high rates of psychotic disorders. Less is known about their psychopathology and how it is treated prior to the peak period of risk for psychotic disorder. There is also a lack of evidence on how functioning is impacted by psychopathology in this population. The aim of this study was to investigate the prevalence and treatment of non-psychotic psychiatric disorders, and how these factors are associated with psychosocial functioning in children and adolescents with 22q11DS. 126 individuals with 22q11DS aged 8–17 participated in the study. Participants were assessed for psychiatric diagnoses, social and role functioning, anxiety and depressive symptoms and IQ. Information on current treatments was collected. 52.4% of the sample presented with at least one psychiatric disorder. Mood and anxiety disorders were the most frequent, followed by behavioural disorder. Individuals with a psychiatric disorder had significantly lower general, role and social functioning. Only 27% of participants with a psychiatric diagnosis were receiving any mental health treatment at the time of assessment. Findings suggest the high prevalence of psychiatric disorders in youth with 22q11DS, which significantly impacts psychosocial functioning. Despite this, psychiatric disorders tend to remain untreated in this population.

Parental warmth and psychiatric disorders among Puerto Rican children in two different socio-cultural contexts

BackgroundParental warmth (PW) has a strong influence on child development and may precede the onset of psychiatric disorders in children. PW is interconnected with other family processes (e.g., coercive discipline) that may also influence the development of psychiatric disorders in children. We prospectively examined the association between PW and child psychiatric disorders (anxiety, major depression disorder, ADHD, disruptive behavior disorders) over the course of three years among Puerto Rican youth, above and beyond the influence of other family factors. MethodsBoricua Youth Study participants, Puerto Rican children 5 to 13 years of age at Wave 1 living in the South Bronx (New York) (SB) and San Juan and Canguas (PR) (n = 2,491), were followed for three consecutive years. Youth psychiatric disorders were measured by the Diagnostic Interview Schedule for Children-IV (DISC-IV). Generalized Linear Mixed models tested the association between PW (Wave 1) and psychiatric disorders in the next two years adjusting for demographic characteristics and family processes. ResultsHigher levels of PW were related to lower odds of child anxiety and major depressive disorder over time (OR = 0.69[0.60; 0.79]; 0.49[0.41; 0.58], respectively). The strength of the association between PW and ADHD and disruptive behavior disorder declined over time, although it was still significant in the last assessment (OR = 0.44[0.37; 0.52]; 0.46[0.39; 0.54], respectively). PW had a unique influence on psychiatric disorders beyond the influence of other parenting and family processes. Stronger associations were observed among girls for depression and ADHD. ConclusionsIncorporating PW behaviors such as acceptance, support, and comforting into interventions focused on parenting skills may help prevent child psychiatric disorders.

Understanding comorbidity among internalizing problems: Integrating latent structural models of psychopathology and risk mechanisms.

It is well known that comorbidity is the rule, not the exception, for categorically defined psychiatric disorders, and this is also the case for internalizing disorders of depression and anxiety. This theoretical review paper addresses the ubiquity of comorbidity among internalizing disorders. Our central thesis is that progress in understanding this co-occurrence can be made by employing latent dimensional structural models that organize psychopathology as well as vulnerabilities and risk mechanisms and by connecting the multiple levels of risk and psychopathology outcomes together. Different vulnerabilities and risk mechanisms are hypothesized to predict different levels of the structural model of psychopathology. We review the present state of knowledge based on concurrent and developmental sequential comorbidity patterns among common discrete psychiatric disorders in youth, and then we advocate for the use of more recent bifactor dimensional models of psychopathology (e.g., p factor; Caspi et al., 2014) that can help to explain the co-occurrence among internalizing symptoms. In support of this relatively novel conceptual perspective, we review six exemplar vulnerabilities and risk mechanisms, including executive function, information processing biases, cognitive vulnerabilities, positive and negative affectivity aspects of temperament, and autonomic dysregulation, along with the developmental occurrence of stressors in different domains, to show how these vulnerabilities can predict the general latent psychopathology factor, a unique latent internalizing dimension, as well as specific symptom syndrome manifestations.

Relationship between Massachusetts Youth Screening Instrument-second version and psychiatric disorders in youths in welfare and juvenile justice institutions in Switzerland.

BackgroundThere is growing evidence that it is important to have well-standardized procedures for identifying the mental health needs of youths in welfare and juvenile justice institutions. One of the most widely used tools for mental health screening in the juvenile justice system is the Massachusetts Youth Screening Instrument-second version (MAYSI-2). To contribute to the body of research examining the utility of the MAYSI-2 as a mental health screening tool; the first objective of the current study was to examine the relationship between the MAYSI-2 and the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime version (K-SADS-PL) in a sample of Swiss youths in welfare and juvenile justice institutions using a cross-sectional design. Secondly, as the sample was drawn from the French-, German- and Italian-speaking parts of Switzerland, the three languages were represented in the total sample and consequently differences between the language regions were analyzed as well. The third objective was to examine gender differences in this relationship.MethodsParticipants were 297 boys and 149 girls (mean age = 16.2, SD = 2.5) recruited from 64 youth welfare and juvenile justice institutions in Switzerland. The MAYSI-2 was used to screen for mental health or behavioral problems that could require further evaluation. Psychiatric classification was based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime version (K-SADS-PL). Binomial logistic regression analysis was used to predict (cluster of) psychiatric disorders from MAYSI-2 scales.ResultsThe regression analyses revealed that the MAYSI-2 scales generally related well to their corresponding homotypic (cluster of) psychiatric disorders. For example, the alcohol/drug use scale identified the presence of any substance use disorder and the suicide ideation scale identified youths reporting suicide ideation or suicide attempts. Several MAYSI-2 scales were also related to heterotypic (cluster of) psychiatric disorders. For example, the MAYSI-2 scale alcohol/drug use, was positively related to any disruptive disorder. Furthermore, the results revealed gender differences in the relationship between the MAYSI-2 and K-SADS-PL (e.g., in the boys’ subsample no MAYSI-2 scale was significantly related to any affective disorder; whereas, in the girls’ subsample the MAYSI-2 scales depressed-anxious and somatic complaints were significantly related to any affective disorder).ConclusionsOverall, The MAYSI-2 seems to serve well as a first-stage screen to identify service needs for youths in welfare and juvenile justice institutions in Switzerland. Its effectiveness to identify the presence of (cluster of) psychiatric disorders differs between genders.

A prospective cohort study of depression course, functional disability, and NEET status in help-seeking young adults.

To examine the associations between depression course, functional disability, and Not in Education or Training (NEET) status in a clinical sample of young adults with mental health problems. Young adults aged 15-25years seeking help from four primary mental health services were invited to participate in a prospective cohort study evaluating the course of psychiatric disorders in youth. Demographic and clinical characteristics, including depressive symptomatology and functioning, were evaluated through clinical interview and self-report at baseline and 12month follow-up. A total of 448 young adults participated (70% female; M: 20.05years, SD=2.85). A significant interaction effect for time and depression course was found, such that those who became depressed reported an increase in functional disability and those whose depression remitted reported a significant reduction in functional disability. Developing depression was not a significant predictor of becoming NEET and vice versa: remitted depression did not make a person more likely to reengage in employment or education. This is the first study to examine the course of depression, functional disability, and NEET rates among help-seeking young adults. This study confirms the importance of symptom reduction for improved functioning; however, functional disability remained greater than that seen in young people in the community and there was no association between a change in depression and a change in NEET status. These results argue that services need to address functional outcomes and reengagement with education and employment in addition to symptom reduction.
