Background: The processes involved in this study were 2-fold. First, we analyzed the levels of resilience and internalized problems (defined as group of emotional symptoms) in children aged 9 to 12 years. Second, we examined whether the relationship between them varies according to the low or high vulnerability of school communities. Methods:…

Autistic youth bullied at school are at risk for school refusal (SR), which may grow from emerging SR (ESR). SR and ESR have been associated with social phobia and separation anxiety among neurotypical youth but these associations have not been studied among autistic youth. The associations between both types of anxiety and in a sample of 71…

This study compared social, executive, emotional, and behavioral characteristics of students with autism spectrum disorder who did and did not display school refusal behavior. The participants were 62 students with autism spectrum disorder without intellectual disability aged 9-16 years attending inclusive schools. Parents first completed…

Background: People with intellectual disabilities often have a multitude of concurrent problems due to the combination of cognitive impairments, psychiatric disorders (particularly anxiety) and related challenging behaviours. Diagnoses in people with intellectual disabilities are complicated. This study evaluates the quality of the diagnoses and…

The present study was conducted with the aim to identify comorbid psychiatric disorders in children with autism spectrum disorders (ASD) (n = 40) and to compare those comorbidity rates to those in children with attention deficit hyperactivity disorder (ADHD) (n = 40). Participants were clinically referred children aged 7-18 years. DSM-IV…

The present study first examined the links between reactive temperament (negative affectivity), regulative temperament (effortful control [EC]) and internalizing problems in adolescents (12-18 years) with anxiety disorders (ANX; N = 39) and without anxiety disorders (nANX; N = 35). Links differed between ANX and nANX participants. Negative…

Inattention is among the most commonly referred problems for school-aged youth. Research suggests distinct mechanisms may contribute to attention problems in youth with anxiety disorders versus youth with attention deficit hyperactivity disorder (ADHD). This study compared children (8-17 years) with anxiety disorders (n = 24) and children (8-16…

Objectives: This study evaluated the efficacy of a novel psychosocial intervention (Collaborative Life Skills, CLS) for primary-school students with ADHD symptoms. CLS is a 12-week program consisting of integrated school, parent, and student treatments delivered by school-based mental health providers. Using a cluster randomized design, CLS was…

Maternal ratings of explosiveness, opposition, and aggression were analyzed in 1609 children 6-16 years of age. Behavior problems were common in autism, ADHD-Combined type, and depression, whereas children with ADHD-Inattentive type, anxiety disorder, and acquired brain injury did not differ from typical controls. More than 40% of children with…

We examined differences among 158 children, 44 with selective mutism (SM; M = 8.2 years, SD = 3.4 years), 65 with mixed anxiety (MA; M = 8.9 years, SD = 3.2 years), and 49 community controls (M = 7.7 years, SD = 2.6 years) on primary caregiver, teacher, and child reports of behavioral and socio-emotional functioning. Children with SM were rated…

Background: Although distinctive neuropsychological impairments have been delineated in children with chromosome 22q11 deletion syndrome (22q11DS), social skills and social cognition remain less well-characterised. Objective: To examine social skills and social cognition and their relationship with neuropsychological function/behaviour and…

Middle school students classified with Emotional Disturbance in two levels of least restrictive environments (LRE)--self-contained classes (SCC) and a self-contained school (SCS)--were compared at the beginning and the end of a school year, using demographics, IQ and achievement testing, a teacher checklist for DSM-IV psychopathology, and standard…

Background: The phenotype of children and adults with fragile X syndrome (FXS) includes a number of problem behaviours such as inattention, social anxiety and aggressive outbursts. However, very little work has been conducted with young children with FXS less than 5 years of age to examine the developmental pathway of problem behaviours in this…
