BackgroundYoung adults who are not in employment, education, or training (NEET) are at risk of long-term economic disadvantage and social exclusion. Knowledge about risk factors for being NEET largely comes from cross-sectional studies of vulnerable individuals. Using data collected over a 10-year period, we examined adolescent predictors of being NEET in young adulthood.MethodsWe used data on 1938 participants from the Victorian Adolescent Health Cohort Study, a community-based longitudinal study of adolescents in Victoria, Australia. Associations between common mental disorders, disruptive behaviour, cannabis use and drinking behaviour in adolescence, and NEET status at two waves of follow-up in young adulthood (mean ages of 20.7 and 24.1 years) were investigated using logistic regression, with generalised estimating equations used to account for the repeated outcome measure.ResultsOverall, 8.5% of the participants were NEET at age 20.7 years and 8.2% at 24.1 years. After adjusting for potential confounders, we found evidence of increased risk of being NEET among frequent adolescent cannabis users [adjusted odds ratio (ORadj) = 1.74; 95% confidence interval (CI) 1.10–2.75] and those who reported repeated disruptive behaviours (ORadj= 1.71; 95% CI 1.15–2.55) or persistent common mental disorders in adolescence (ORadj= 1.60; 95% CI 1.07–2.40). Similar associations were present when participants with children were included in the same category as those in employment, education, or training.ConclusionsYoung people with an early onset of mental health and behavioural problems are at risk of failing to make the transition from school to employment. This finding reinforces the importance of integrated employment and mental health support programmes.

BackgroundResults of adulthood mental health of those born late-preterm (34 + 0–36 + 6 weeks + days of gestation) are mixed and based on national registers. We examined if late-preterm birth was associated with a higher risk for common mental disorders in young adulthood when using a diagnostic interview, and if this risk decreased as gestational age increased.MethodA total of 800 young adults (mean = 25.3, s.d. = 0.62 years), born 1985–1986, participated in a follow-up of the Arvo Ylppö Longitudinal Study. Common mental disorders (mood, anxiety and substance use disorders) during the past 12 months were defined using the Composite International Diagnostic Interview (Munich version). Gestational age was extracted from hospital birth records and categorized into early-preterm (<34 + 0, n = 37), late-preterm (34 + 0–36 + 6, n = 106), term (37 + 0–41 + 6, n = 617) and post-term (⩾42 + 0, n = 40).ResultsThose born late-preterm and at term were at a similar risk for any common mental disorder [odds ratio (OR) 1.11, 95% confidence interval (CI) 0.67–1.84], for mood (OR 1.11, 95% CI 0.54–2.25), anxiety (OR 1.00, 95% CI 0.40–2.50) and substance use (OR 1.31, 95% CI 0.74–2.32) disorders, and co-morbidity of these disorders (p = 0.38). While the mental disorder risk decreased significantly as gestational age increased, the trend was driven by a higher risk in those born early-preterm.ConclusionsUsing a cohort born during the advanced neonatal and early childhood care, we found that not all individuals born preterm are at risk for common mental disorders in young adulthood – those born late-preterm are not, while those born early-preterm are at a higher risk. Available resources for prevention and intervention should be targeted towards the preterm group born the earliest.

SummaryThe paper presents an overview of the WHO World Mental Health (WMH) Survey Initiative and summarizes recent WMH results regarding the prevalence and societal costs of mental disorders. The WMH surveys are representative community surveys that were carried out in 28 countries throughout the world aimed at providing information to mental health policy makers about the prevalence, burden, and unmet need for treatment of common mental disorders. Results show that mental disorders are commonly occurring in all participating countries. The inter-quartile range (IQR: 25th-75th percentiles) of lifetime DSM-IV disorder prevalence estimates (combining anxiety, mood, disruptive behavior, and substance disorders) is 18.1-36.1%. The IQR of 12-month prevalence estimates is 9.8-19.1%. Analysis of age-of-onset reports shows that many mental disorders begin in childhood-adolescence and have significant adverse effects on subsequent role transitions. Adult mental disorders are found in the WMH data to be associated with high levels of role impairment. Despite this burden, the majority of mental disorders go untreated. Although these results suggest that expansion of treatment could be cost-effective from both the employer perspective and the societal perspective, treatment effectiveness trials are needed to confirm this suspicion. The WMH results regarding impairments are being used to target several such interventions.

Aims: To explore associations between experiences of mental illness, migration status and languages spoken among Pacific adults living in NZ. Methods: SURVEY FREQ and SURVEY LOGISTIC procedures in SAS were applied to data from Te Rau Hinengaro: The New Zealand (NZ) Mental Health Survey, a survey of 12,992 New Zealand adults aged 16 and over in 2003/2004. Pacific people were over sampled and this paper focuses on the 2374 Pacific participants but includes, for comparison, 8160 non-Maori-non-Pacific (NMNP) participants. Results: Pacific migrant respondents had the lowest prevalence of mental disorders compared to other Pacific peoples. However, Pacific immigrants were also less likely to use mental health services, suggesting an increased likelihood of experiencing barriers to available mental health care. Those who were born in NZ and who were proficient in a Pacific language had the lowest levels of common mental disorders, suggesting a protective effect for the NZ-born population. Additionally, access to mental health services was similar between NZ-born people who spoke a Pacific language and those who did not. Conclusions: We conclude that, given the association between Pacific language and reduced mental disorder, there may be a positive role for Pacific language promotion in efforts to reduce the prevalence of mental health disorder among Pacific communities in NZ.


Schools have become the default mental health providers for children and adolescents, but they are often poorly equipped to meet the mental health needs of their students. The introduction tackles how to make students eligible for school-based services using the Individuals with Disabilities Education Act or Section 504 of the Rehabilitation Act. Using the new DSM-5 as an organizing principle, this book then addresses the 12 most common mental disorders of childhood and adolescence, ages 3–18. While there are many books that address child and adolescent psychopathology, this book focuses on how to help students with mental disorders in pre-K–12 schools. Each chapter addresses the prevalence of a disorder in school-age populations, appropriate diagnostic criteria, differential diagnosis, comorbid disorders, rapid assessment instruments available, school-based interventions using multitiered systems of support, and easy-to-follow suggestions for progress monitoring. Unique to this book, each chapter has detailed suggestions for how school-based clinicians can collaborate with teachers, parents, and community providers to address the needs of youth with mental health problems so that school, home, and community work together. Each chapter ends with a list of extensive web resources and a real-life case example drawn from the clinical practice of the authors. The final chapter addresses two newly proposed diagnoses for self-harm in the DSM-5 and brings a cautious and sensible approach to assessing and helping students who may be at risk for serious self-injury or suicide.
