This exploratory study aimed to explore the association between depression and self-harming behaviour in adolescence and the timing of diagnosis for autism spectrum disorder. We analysed data on 11,320 14 year olds, including 396 children with autism spectrum disorder, from the UK Millennium Cohort Study. Exposures were the timing of diagnosis for…

Introduction: Challenging behaviors are common in individuals with developmental disabilities and pose significant challenges to their well-being and that of their families and communities. Method: We explored the occurrence and predictors of self-injurious behavior and aggressive/destructive behavior in 372 Canadian youths (aged 4-20 years) with…

During the immediate period following psychiatric hospitalization, adolescents are at increased risk for suicide attempts and rehospitalization. Because most adolescents return to school during this time, school-related experiences are important considerations during the transition from inpatient hospitalization. This study sought to understand…

A family systems framework guided our investigation of self-injurious behavior (SIB) in adolescents. As part of a larger study, we collected data examining SIB and family functioning from 29 adolescents (M[subscript age] = 15.66) and their caregivers. These adolescents with traits of borderline personality disorder were seeking counseling from…

Background: While empirical testing of many of the interRAI Child and Youth Mental Health (ChYMH) assessment scales have been found to be reliable and valid across both child and adult samples, other scales have yet to be psychometrically evaluated within child populations. Objective: The current study evaluates the psychometric properties of the…

Background: Non-suicidal self-injury (NSSI) is a serious and alarming phenomenon during adolescence. There is a need for understanding the intrapersonal variables that might contribute to the maintenance of these self-injurious behaviors. Objective: This study aims to concurrently compare intrapersonal variables between adolescents with and…

Adolescent risk-taking can potentially result in serious individual and societal consequences. Previous research demonstrates that emotional and behavioral problems, particularly externalizing behaviors, are significantly associated with an array of risky behaviors such as substance use, sexual behavior, injury, and violence. However, the…

Background: Non-suicidal self-injury (NSSI) is a serious and relatively prevalent problem in adolescence. Although several studies have identified risk factors for the aetiology and maintenance of NSSI, little is known about the impact of individual and contextual variables in such pervasive behaviors among adolescents. Objective: This paper aims…

This study examined characteristics and biopsychosocial predictors of nonsuicidal self-injury in a sample (N = 753) of youth in residential care admitted between 2005 and 2010. To model the data, the authors used t-tests, chi-square tests, and multiple logistic regressions stratified by gender. Results suggested that 12% of youth engaged in…

The preceding article by Hawton and colleagues reporting on a prospective study of adolescents presenting with self-harm to Accident and Emergency departments (A&E) is one of the largest epidemiological studies to examine the long-term outcomes of self-harm in children and adolescents. After a median of 6 years nearly 30% re-presented to A&E with…

Objective: Longitudinal data on adolescent self-injury are rare. Little is known regarding the associations between various forms of self-injurious thoughts and behaviors over time, particularly within community samples that are most relevant for prevention efforts. This study examined nonsuicidal self-injury (NSSI) as a time-invariant,…

Runaway and homeless youth often have a constellation of background behavioral, emotional, and familial problems that contribute to stress and maladaptive behaviors, which, in turn, can lead to self-harming and suicidal behaviors. The current study examined the roles of stress and maladaptive behaviors as mediators between demographic and…

Children with autism spectrum disorders (ASD) are at high risk for co-occurring psychiatric disorders. Previous research has suggested that restricted and repetitive behaviors (RRB) are associated with symptoms of co-occurring psychiatric disorders in individuals with ASD, but this relationship is not well understood. The current study…

Objective: To evaluate the clinical and prognostic significance of suicide attempts (SAs) and nonsuicidal self-injury (NSSI) in adolescents with treatment-resistant depression. Method: Depressed adolescents who did not improve with an adequate SSRI trial (N = 334) were randomized to a medication switch (SSRI or venlafaxine), with or without…

Sleep disturbance is an early marker for bipolar disorder (BD) onset in youth. We characterized sleep quality in adolescents experiencing mania within the last 6-12 months. We examined the association between mood and sleep in 27 adolescents with BD and 24 matched healthy controls (HC). Subjects were assessed by parent and teen report of sleep, a…
