This study evaluated the interplay of attention deficit hyperactivity disorder (ADHD) symptom severity, deviant peer group affiliation, oppositional defiant disorder (ODD), and conduct disorder (CD) as risk factors among 142 adolescents with childhood ADHD. Deviant peer affiliation mediated the relation between childhood ADHD symptoms and 6…

This study examined whether 2 aspects of disruptive behaviors (i.e., hyperactivity-inattention and aggressiveness-opposition) observed in kindergarten predict noncompletion of high school by early adulthood. Also investigated was whether other personal characteristics such as anxiety or prosociality as well as parent child-rearing attitudes and…

Self-management procedures have been used in school settings to successfully reduce problem behaviors, as well as to reinforce appropriate behavior. A multiple-baseline across participants design was applied in this study to evaluate the effects of using a self-management procedure to enhance the classroom preparation skills of secondary school…

Most attention deficit hyperactivity disorder (ADHD) research has compared cases with unaffected controls. This has led to many associations, but uncertainties about their specificity to ADHD in contrast with other disorders. We present a selective review of research, comparing ADHD with other disorders in neuropsychological, neurobiological and…

This study evaluated the Planning, Attention, Simultaneous, and Successive (PASS) characteristics of children assessed for Attention Deficit/Hyperactivity Disorder (ADHD referred), children with a Reading Disability (RD), and children in Regular Education (RE). The Cognitive Assessment System (CAS) was used to assess PASS processes for the 119…

The relationship between executive function and comorbid diagnoses in ADHD children is examined. One hundred six children between 7 and 15 years of age are assessed using the Tower of London (TOL), a test of executive function, and the Kiddie Schedule of Affective Disorders and Schizophrenia, Present and Lifetime Version, a diagnostic interview.…

Behavior modification is an evidence-based treatment for children with attention-deficit/hyperactivity disorder (ADHD). Time-out from positive reinforcement is one behavior-modification procedure commonly recommended to manage disruptive or noncompliant behavior. This investigation examined the effects of time-out on children's behavior within the…

Aggressive behavior in childhood has long been separated into that which is proactively motivated and that which is reactive. We report a meta-analytic review of the existing empirical literature that examines the associations of each type of aggression with six indices of psychosocial adjustment: internalizing problems, emotional dysregulation…

Children with attention-deficit hyperactivity disorder (ADHD) are reported to have more difficulties with self-regulation and emotional regulation. Current ADHD models suggest a primary deficit in behavioral inhibition causes secondary deficits in executive functions, impacting on emotional regulation. This study examined the relationship of…

The present study investigated the working memory abilities of children with attention deficit/hyperactivity disorder (ADHD) as measured by the Stanford-Binet Intelligence Scales, Fifth Edition (SBV). In a retrospective causal-comparative design, the archival data of 46 ADHD children were compared to 59 nondiagnosed children. The ADHD children…

Objective: The purpose of this study was to assess heritability of activity, attention, and impulsivity by comparing young monozygotic (MZ) twins with dizygotic (DZ) twins using objective measures. Method: The OPTAx test is an infrared motion analysis to record the movement pattern during a continuous performance test. Seventeen MZ and 12 same…

This pilot study examined the effects of a short-term music therapy program on the classroom behaviours of newly arrived refugee students who were attending an intensive "English as a Second Language" secondary school. A cross-over design with two five-week intervention periods was employed with group music therapy sessions conducted one…

This article reviews research on the behavioral and molecular genetics of reading and, where available, spelling. Recent research is summarized, suggesting that reading and spelling appear to share a common genetic basis, and that dyslexia lies on a genetic continuum with normal variance in reading skill. Research also suggests that while many of…

In this paper we briefly review three areas of research on attention-deficit/hyperactivity disorder (ADHD) that have implications for the educational context. These areas are: (a) gender differences in ADHD, (b) inattention symptoms and academic risk, and (c) working memory and ADHD. We highlight the critical role that the school context plays in…

Although many psychopharmacologic treatments and behavioral or cognitive behavioral interventions have been established as evidence-based practices, they have seldom been directly compared to one another as to outcome in children with emotional or behavioral disorders (EBD). In this paper, we present findings from 6 recent randomized clinical…
