Children with psychiatric disorders often demonstrate gross motor problems. This study investigates if the reverse also holds true by assessing psychiatric symptoms present in children with gross motor problems. Emotional, behavioral, and autism spectrum disorders (ASD), as well as psychosocial problems, were assessed in a sample of 40 children…

Relatively little is known about the potential interplay between genetic and environmental influences on attention-deficit/hyperactivity disorder (ADHD), including gene-environment interaction (GxE). There is evidence that parenting behavior interacts with offspring genotype in the development of externalizing problems, but studies have largely…

Objective: A callous-unemotional (CU) subtype of conduct disorder (CD) has been proposed as an addition to the fifth edition of the "Diagnostic and Statistic Manual of Mental Disorders (DSM-5)." This study tested the hypothesis that young girls with the CU subtype of CD would exhibit more severe antisocial behavior and less severe internalizing…

Visual line bisection is a reliable and valid laterality task that is typically used with patients with acquired brain damage to assess right hemisphere functioning. Neurologically normal individuals tend to bisect lines to the left of the objective midline whereas those with right parietal damage bisect lines to the right. In this study children…

The authors examined behavior problems in a matched sample of 58 youths with persistent dyscalculia (PD) and nonpersistent dyscalculia (NPD). Participants were classified as having dyscalculia at age 10-11 years. Parents completed the Child Behavior Checklist for their children at ages 10-11, 13-14, and 16-17 years, while the youths did so at the…

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…

As schooling at least partly concerns itself with formulating relationships, it is understandable that certain behaviours are seen as necessary to the advancement of learning and teaching. However, how pupil behaviour is judged is an indication of wider political perspectives, which in turn assist in the categorization of behaviour. In this…

The current study replicated the positive effects of performance feedback on treatment integrity and extended previous work by examining reactivity using a multiple baseline design with alternating treatments for observer-present and observer-absent conditions on teachers' implementation of a classwide behavior plan. No differences were found…

In a randomized controlled trial we tested the role of genetic differences in explaining variability in intervention effects on child externalizing behavior. One hundred fifty-seven families with 1- to 3-year-old children screened for their relatively high levels of externalizing behavior participated in a study implementing Video-feedback…

Building on empirical documentation of children's involvement in interparental conflicts as a weak predictor of psychopathology, we tested the hypothesis that involvement in conflict more consistently serves as a moderator of associations between children's emotional reactivity to interparental conflict and their psychological problems. In Study…

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…

The current study examined the incremental utility of rating scales, a structured diagnostic interview, and multiple informants in a comprehensive assessment of attention-deficit/hyperactivity disorder (ADHD). The sample included 185 children with ADHD (M[subscript age] = 9.22, SD = 0.95) and 82 children without ADHD (M[subscript age] = 9.24, SD =…

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…

The research base on how to effectively intervene to improve the reading fluency of students with academic and behavioral disabilities at the middle school level does not provide a strong support for evidence- based practices with this age group. The purpose of this study was to extend the body of research on reading fluency interventions to…

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…
