Youth violence in both the juvenile justice system and in juveniles with intellectual disabilities is a significant and costly problem in the United States. An increasingly large number of youth with intellectual disabilities are being placed in secure juvenile justice facilities without specialized resources. In addition, these facilities are…

While a considerable number of youth with autism spectrum disorder exhibit impaired self-regulation (dysregulation), little is known about the neural correlates of dysregulation in autism spectrum disorder. In a sample of intellectually able boys with autism spectrum disorder (further categorized as those with and without dysregulation) and…

Children with early-onset conduct problems (EOCP) and callous-unemotional (CU) traits are highly resistant to treatment and cost society significantly more than their healthy counterparts. Employing a multiple baseline design, 13 males (9.0-10.2 years of age) with a history of school suspensions were sequentially introduced to KooLKIDS, a…

A young man with intellectual disabilities (ID) and mental illness, who had previously been taught to successfully manage his aggressive behavior by using "Meditation on the Soles of the Feet," reported that he shared his mindfulness practice with his peers with ID. When requested by his peers, and without any training as a therapist, he began to…

This research examined the hypothesis that temperament and sex moderate the contribution of peer victimization to children's subsequent adjustment (aggression and depressive symptoms). Children (125 boys, 158 girls; M age = 7.95 years, SD = 0.32; 77.7% White, 22.3% minority) and teachers reported on overt and relational victimization. Parents…

The current paper provides external validation of the bifactor model of ADHD by examining associations between ADHD latent factor/profile scores and external validation indices. 548 children (321 boys; 302 with ADHD), 6 to 18 years old, recruited from the community participated in a comprehensive diagnostic procedure. Mothers completed the Child…

Most theorizing about desistance from antisocial behavior in late adolescence has emphasized the importance of individuals' transition into adult roles. In contrast, little research has examined how psychological development in late adolescence and early adulthood contributes desistance. The present study examined trajectories of antisocial…

It is widely accepted that conflict-related goals, skills, and strategies are linked. Yet it is rarely explored how these factors relate to each other and how they jointly promote or inhibit aggressive behaviors. The aim of this study is to provide answers to these questions. Data were derived from a structured questionnaire administered to 660…

We studied emotional aspects of social information processing (SIP) and their specific relations with reactive and proactive aggression in 54 boys ages 7 to 13 who had been referred for aggressive behavior problems and a comparison group. Participants listened to vignettes concerning provocations by peers and answered questions concerning SIP, own…

Twelve aggressive second grade boys participated in daily, 30-minute, individual sessions for 6 weeks to test the hypothesis that the "Think Aloud" self control training program, which involves modeling and verbalization of cognitive activities, would lead to improvement in test performance and teacher ratings of classroom behavior in…

Examined social cognitive skills in aggressive and nonaggressive delinquent youths with high or low behavioral functioning. Found significant interaction on problem-solving skills, with higher functioning, non-aggressive youths performing better than lower functioning counterparts; no differences occurred within aggressive groups. (Author/NB)

A broad spectrum behavior therapy approach was used to treat physical aggression in 5 brain-injured males (ages 18-28). The approach employed high density reinforcement, reinforcer sampling, environmental control, selection of appropriate responses, inconvenience review, self-control training, and self-monitoring. All five subjects showed…

Examined anger, hostility, and depression across domestically violent men, generally assaultive men, and nonviolent control group. Domestically violent and generally assaultive men evidenced significantly higher levels of anger and hostility than did control subjects, but domestically violent men tended to be significantly depressed. Supports…

Data from a 25-year study of 194 individuals indicated that teacher and peer reports of aggression, compliance, and self-control at age 8 distinguished high-agreeable from low-agreeable 33-year-olds. High-agreeable childhood types had fewer disobedience and concentration problems than low-agreeable childhood types. High-agreeable childhood boys…

Compared were two samples of 173 and 95 aggressive and normal 5- to 8-year-old boys on measures of verbal and cognitive development. Aggressive boys were significantly lower than normal boys on nonverbal tests but not on verbal tests. The pattern of test performance which distinguished aggressive and normal was consistent with the hypothesis that…
