We examined the predictive utility of the Behavior Assessment System for Children-2 Behavioral and Emotional Screening System (BASC-2-BESS) and Strengths and Difficulties Questionnaire (SDQ) in identifying students with a mental disorder. Data were collected in a two-stage study over 34 months with kindergarten-12th grade (K-12) students (aged…

Background and purpose: The purpose of this study was to assess the level of mental disorders and challenging behaviour in individuals with intellectual disability (ID) supported by specialized services, but without a prior psychiatric diagnosis, and to compare the levels of different disorders depending on the severity of ID. Methods: This is a…

Background: Despite agreement that restrictive intervention (RI) should only be used as a last resort and for as long as required, little is known about long-term RI among individuals with a disability. This study examines long-term RI use. Method: From the Restrictive Intervention Data System dataset from Victoria, Australia, a cohort of 1,414…

Objective: To examine changes in diagnoses/treatment for 12 mental health (MH) conditions, previous use of campus MH services, and willingness to seek MH services in the future. Participants: ACHA-NCHA II participants from 2009 to 2015 (n = 454,029). Methods: Hierarchical binary logistic regression with step 1 controlling for demographics and step…

An emotional/behavioral disorder is a mental health disability characterized by intensive internalized behaviors (e.g., anxiety, depression) and/or externalized behaviors (e.g., physical aggression, verbal aggression). Autism is a neurodevelopmental disorder characterized by deficits in social communication and repetitive behaviors (i.e., stereo…

A systematic review of autism spectrum disorder and substance use and abuse was conducted based on the Preferred Reporting Items for Systematic Review and Meta-Analysis protocol guidelines (an internationally recognized standardized methodological framework for conducting systematic review). The objectives of the review were to update and extend…

Though schools have become the default mental health providers for children and adolescents, they are poorly equipped to meet the mental health needs of their students. "Evidence-Based Practice in School Mental Health" differs from other books that address child and adolescent psychopathology by focusing on how to help students with…

Children and youth with mental health issues and learning difficulties are common in the juvenile justice system and finding ways to effectively rehabilitate, treat, and educate them is complicated, yet imperative. In this article, we examine the prevalence rates of mental health disorders in youth involved in the juvenile justice system, discuss…

Background: The literature on the prevalence of mental disorders affecting children and adolescents has expanded significantly over the last three decades around the world. Despite the field having matured significantly, there has been no meta-analysis to calculate a worldwide-pooled prevalence and to empirically assess the sources of…

School counselors are in a prime position to collaborate with school and community stakeholders to both prevent and respond to the challenges experienced and exhibited by students with one or more disruptive behavior disorders (DBD). In this article, the DBDs discussed include conduct disorder, oppositional defiant disorder, intermittent explosive…

Background: In the general population there are statistically significant urban-rural differences in the rate of common mental disorders. In people with intellectual disability (ID) no study has attempted to address this issue. Aims: To compare the prevalence of mental illness, autism spectrum disorder (ASD) and behaviour disorder in people with…

Three main aims of this study were to ascertain the prevalence rate of smoking among adolescent psychiatric outpatients; estimate smokers' degree of nicotine dependence; and investigate the relationship between smoking and common mental health disorders. Face-to-face interviews were conducted on 93 patients ages 13-18 presenting to an adolescent…

Children with intellectual and developmental disabilities are at heightened risk for mental disorders. Using current diagnostic criteria, disruptive behavior disorders, specifically Attention-Deficit/Hyperactivity Disorder (ADHD), appear to be the most prevalent co-occurring disorders. However, the validity of ADHD as a diagnosis for children and…

Accurate and regularly updated prevalences are critical to guide both prevention and policy. However, despite their impact on public health, the prevalence of behavioral and mental health problems such as child maltreatment and intimate partner violence (IPV) are collected infrequently (e.g., once per decade or less). The purpose of this study is…

Background: The assessment of victims of child sexual abuse (CSA) is now a recognized aspect of clinical work for both CAMH and adult services. As juvenile perpetrators of CSA are responsible for a significant minority of the sexual assaults on other children, CAMH services are increasingly approached to assess these oversexualized younger…
