Background: Emotional and behavioural problems as well as a lack of social competence are common in adolescents with borderline intellectual functioning and impair their social and vocational integration. Group interventions specifically developed for this target group are scarce and controlled evaluation studies are absent. Methods: A…

Background: We investigated the relationship between low mood and challenging behaviour in people in the severe and profound range of intellectual disability, while controlling for the presence of potentially confounding variables such as diagnosis of autism, physical and sensory problems and ill health. Methods: The key workers of 52 people with…

During the first week of a Head Start program in September, Jamal, almost 5 years old, punched another child in the stomach. An assistant looked after the hurt child. Charlane, the teacher, approached Jamal, saying, "There is no hurting children in this class." She marched him to a time-out chair where Jamal sat with his head down. The following…

This study examined the effects of marital conflict on Korean children's psychological adjustment and appraisal of hypothetical marital conflict situations. Children between the ages of 10 and 12 were divided into "high-conflict" (n = 58) and "low-conflict" (n = 58) groups based on their self-reported degree of perceived…

Several studies have demonstrated that the family members of adolescents with mental diseases experience distress, anxiety and depression, as well as economic strain, all of which contribute to physical and psychological caregiver morbidity. The aim of this study was to assess the effectiveness of intervention to improve the caregiving experience…

One pressing issue facing parenting interventions for disruptive behaviors of young children is forecasting who will benefit from participation. The purpose of this study was to examine four personal and interpersonal predictors (i.e., parent depressive symptoms, parent education, coparent conflict, and marital status) of engagement (i.e., number…

Evidence for shared heritable influences across domains of substance use suggests that some genetic variants influence broad risk for externalizing behaviors. Theories of externalizing psychopathology also suggest that genetic liability for substance use manifests as temperamental risk factors, particularly those related to behavioral…

Tier 2 interventions are implemented similarly across students and thus serve as an efficient and cost-effective method of behavior support in school settings. Check-in/check-out is a Tier 2 intervention with documented effectiveness (e.g., Hawken & Horner, 2003; Todd, Campbell, Meyer, & Horner, 2008). Key features of the intervention…

Background: Identifying how genetic risk interacts with experience to predict psychopathology is an important step toward understanding the etiology of mental health problems. Few studies have examined genetic risk by experience interaction (GxE) in the development of childhood psychopathology. Methods: We used both co-twin and parent mental…

Background: Recently, a highly heritable behavioral phenotype of simultaneous deviance on the Anxious/Depressed, Attention Problems, and Aggressive Behavior syndrome scales has been identified on the Child Behavior Checklist (CBCL-Dysregulation Profile, CBCL-DP). This study aims to investigate psychosocial adversity and impairment of the CBCL-DP.…

Purpose: The purpose of this paper is to examine the relationship between cyberbullying victimization and internalizing problems among the youth. Moderator effects of a friendship quality were also investigated to examine if higher friendship quality moderated the negative effects of cyberbullying on psychological states of students.…

Social problems are a prevalent feature of ADHD and reflect a major source of functional impairment for these children. The current study examined the impact of working memory deficits on parent- and teacher-reported social problems in a sample of children with ADHD and typically developing boys (N = 39). Bootstrapped, bias-corrected mediation…

This study investigated how parenting accounted for interindividual differences in developmental trajectories of different child behaviors across childhood and adolescence. In a cohort sequential community sample of 1,049 children, latent class growth analysis was applied to three parent-reported dimensions (monitoring, positive parenting,…

Studies of brain development suggest that the increase in risk taking observed during adolescence may be due to insufficient prefrontal executive function compared to a more rapidly developing subcortical motivation system. We examined executive function as assessed by working memory ability in a community sample of youth (n = 387, ages 10 to 12…

Children with developmental disabilities are at substantially greater risk of developing emotional and behavioural problems compared to their typically developing peers. While the quality of parenting that children receive has a major effect on their development, empirically supported parenting programs reach relatively few parents. A recent trend…
