The association between affiliating with aggressive peers and behavioral, social and psychological adjustment was examined. Students initially in 3rd, 4th, and 5th grade (N = 427) were followed biannually through 7th grade. Students' peer-nominated groups were identified.

Students with disabilities who display serious (e.g., dangerous) problem behaviors are frequently educated in alternative school settings. Although there is considerable research on intervention approaches (e.g., function-based support) to support individual students with challenging behaviors, there is a lack of research on schoolwide…

An archival study was conducted to document (a) types of challenging behavior, and (b) functional assessment outcomes, for a sample of persons with developmental disabilities who were referred to community-practicing behavior analysts for assessment and treatment of challenging behavior. Functional assessment reports, prepared by 17 behavior…

Background: Antisocial behaviour may partly develop as a consequence of psychopathic personality. However, neither the direction of effects nor the aetiology of the association has previously been clarified. The aim in this study was to investigate the direction of effects between psychopathic personality and antisocial behaviour, and to…

Researchers have demonstrated the unique, harmful, and…

Early aggression is a problem in its own right and a risk factor for further developmental problems. Although both effortful control and social information processing (SIP) skills are negatively associated with aggression and are targeted by aggression prevention programs, little is known about the relation between them or about their joint…

Positive school climate alone cannot prevent all variables that may contribute to the expression of aggression. Nevertheless, positive school climates influence…

The quantitative study, based on student surveys (n = 624), compared norms supporting dating violence by sex, race/ethnicity, and dating status, and it examined the relation between dating violence norms…

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…

Background: Studies have shown that staff who support adults with intellectual disabilities (ID) are exposed to challenging behaviour in their work including client aggression. Exposure to aggressive behaviour has been associated with staff stress and burnout. Study samples have been small however, and there has been very little data exploring…

The development of aggressiveness between 5 and 17 years and some parental influences on this development were analyzed using data from Germany. International studies have shown a "camel humps" curve, i.e., a peak of aggression of children (primarily boys) between 2 and 4 years and a second peak of antisocial or aggressive behavior of…
