The present study investigated prenatal and early postnatal risk factors associated with developmental patterns of disruptive behaviors (DBs; e.g., hyperactivity-impulsivity, noncompliance, physical aggression) from ages 1.5 to 5 years in a population birth cohort (N = 2,057; 50.7% boys). Six high-trajectory classes obtained by latent growth…

This study aimed to investigate the predictive effect of problematic behaviours on cognitive tempo and attention level of 60-66 months old children attending preschool education institutions. The research data were obtained from 155 children between 60 and 66 months old attending independent kindergartens affiliated to the Ministry of National…

Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

The present study examined the utility of video self-modeling (VSM) for reducing externalizing behaviors (e.g., aggression, conduct problems, hyperactivity, and impulsivity) observed within the classroom environment. After identification of relevant target behaviors, VSM interventions were developed for first and second grade students (N = 4),…

This project examined the unique predictive validity of parent ratings of toddler-age aggression, oppositionality, inattention, and hyperactivity-impulsivity to academic achievement at school-age in a sample of 566 high-risk children and families. The study also investigated potential indirect effects of the Family Check-Up on school-age academic…

This study examined the structural relations of preadolescents' inattention and hyperactivity/impulsivity, aggressive and prosocial behaviors, and peer functioning. There were 739 fourth (n = 239) and fifth (n = 500) graders (52.23% boys) in Taiwan who participated in this study. Preadolescents' inattention and hyperactivity/impulsivity were…

This study examined the effectiveness of a treatment program comprised of several components based on evidence-based treatments (EBTs) for disruptive behavior problems delivered to youth participating in a school mental health program in an underserved community in the Appalachian region. Participants were 117 children in kindergarten through 6th…

Adolescents with substance use and conduct disorders have high rates of aggression and attention deficit hyperactivity disorder (ADHD), all of which have been characterized in part by impulsivity. Developing measures that capture impulsivity behaviorally and correlate with self-reported impulsivity has been difficult. One promising behavioral…

The present study was designed to define the relationship between the supposed syndrome of hyperactivity and that of aggressive conduct disorder. (Author/DB)

Operant and cognitive behavior modification procedures were used to decrease impulsive aggressive responding by six hyperaggressive children, aged 7-11, in interpersonal problem situations. The procedures sought to improve participants' alternative response repertoires and develop internal speech as a self-control mechanism. Compared to controls,…

The paper reviews research studies on identification and treatment of attention-deficit hyperactivity disorder (ADHD). Studies investigating the three primary ADHD dimensions of inattention, hyperactivity, and impulsiveness are initially cited, followed by a review of research in the related dimensions of cognitive attributions/locus of control,…
