Our study examined young children's pre-academic and social skills in relation to parental locus of control and children's behaviours of ADHD. The participants were parents of 1,502 children from four Chinese kindergartens (M[subscript age] = 4.59, SD = 0.93; Girls: 51.40%). Data on six domains of children's pre-academic and social skills,…

Relationships between sluggish cognitive tempo (SCT) and age and IQ were investigated in children with autism and/or ADHD covering broader age and IQ ranges than in previous studies. Mothers rated 1436 children with autism and 1,056 with ADHD (2-17 years, IQs 9-149) on Pediatric Behavior Scale SCT items. Increasing age correlated with SCT in the…

We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5-12 years. Children (n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child…

Introduction: The primary aim of this retrospective study was to assess differential associations between sleep disturbances with externalizing/internalizing problems, ADHD profiles (inattention, hyperactivity/impulsivity), and social impairment among children with ADHD, autism spectrum disorder (ASD), and comorbid diagnoses (ASD+ADHD). Methods:…

The purpose of this study was to investigate the self-perception bias (SPB) in adolescents with attention-deficit hyperactivity disorder (ADHD). The SPB was defined as adolescent underestimation of their learning and behavior problems in comparison to parent- or teacher-reports or a standardized achievement test. The sample comprised 74…

We examined the extent to which children's skilled understanding and production of appropriate language (verbal ability) may relate to their peer functioning. Participants included two independent samples of children with and without Attention-Deficit/Hyperactivity Disorder (ADHD; Study 1, N = 124; Study 2, N = 137) who were administered a…

To evaluate the relative efficacy of two reading programs with and without adjunctive stimulant medication for children with attention-deficit/hyperactivity disorder and comorbid reading disorder (ADHD+RD). Sixty-five children (7-11 years in age) were assigned randomly to one of three intensive remedial academic programs (phonologically or…

We explored internal control of behavior using direct observation and parent report. Previous research has found that both the delay of gratification task and parent-reported effortful control predict later social ability and more positive outcomes in typically developing children. Children with autism spectrum disorder have previously been…

Preschool parent interventions may produce downstream benefits if initial intervention gains are sustained and improve later socialization experiences. This study explored associations between initial effects of the REDI (Research-based Developmentally Informed) Parent program and later benefits. A randomized trial involving 200 Head Start…

Performance patterns on verbal subtests from the WISC-IV were compared between a clinically-referred sample of children with either autism spectrum disorders (ASD) or attention deficit/hyperactivity disorder (ADHD). Children with ASD demonstrated a statistically significant stepwise pattern where performance on Similarities was best, followed by…

Background: Attention-deficit/hyperactivity disorder (ADHD) is a chronic and pervasive developmental disorder that is not restricted to the childhood years. Methods: This paper reviews non-pharmacological interventions that are available at present for preschoolers, school-age children, adolescents and adults. Results: The most appropriate…

This study evaluated the clinical significance of measuring between session parental adherence on child and parent outcomes for 51 children (age 4 to 8.5 years) with attention deficit/hyperactivity disorder (ADHD) in a multimodal group training program. Three group treatment conditions: (a) child-only treatment (C1), (c) child and parent training…

This review integrates and evaluates research conducted on possible contributing factors to peer relationship problems of children with attention deficit/hyperactivity disorder (AD/HD). Substantial evidence suggests that children with AD/HD have serious problems in multiple aspects of their relationships with peers. Difficulties resulting from…

Understanding social interactions is crucial for development of social competence. The present study was one of the first to utilize direct and indirect measures of social perception to explore possible differences among children with nonverbal learning disability (NLD), Asperger's Syndrome (AS), Attention Deficit Hyperactivity Disorder-Combined…

Objective: The objectives of this study were to evaluate whether behaviors that differentiate children and adolescents with ADHD from those without are related to the primary diagnostic criteria (i.e., inattention and impulsivity--hyperactivity), symptoms of comorbid conditions, functional impairment, or a combination, and to determine whether…
