Children with autism and autism spectrum disorders have a high rate of irritability and aggressive symptoms. In one study up to 20% of children with autism have symptoms of irritability and aggression including aggression, severe tantrums, and deliberate self injurious behavior (Lecavalier [2006] "J. Autism Dev. Disord." 36:1101-1114.). These…

The role of hostile attributional style (HAS) in antisocial development has been well-documented. We analyzed longitudinal data on 585 youths (48% female; 19% ethnic minority) to test the hypothesis that response evaluation and decision (RED) mediates the relation between HAS and antisocial behavior in adolescence. In Grades 10 and 12, adolescent…

An integrative model is proposed for understanding the development of physical and relational aggression in early and middle childhood. The central goal was to posit a new theoretical framework that expands on existing social-cognitive and gender schema models (i.e., Social Information-Processing Model of Children's Adjustment [N. R. Crick & K. A.…

Reliability and concurrent validity of the Behavior Problems Inventory (BPI-01; Rojahn et al., 2001) was examined in a sample of 130 community residing adults with mild to profound intellectual disabilities with high rates of behavior problems and concurrent mental health problems. The BPI-01 and the Inventory for Client and Agency Planning (ICAP;…

This study examined relations among family environment, cortisol response, and behavior in the context of a randomized controlled trial with 92 children (M = 48 months) at risk for antisocial behavior. Previously, researchers reported an intervention effect on cortisol response in anticipation of a social challenge. The current study examined…

The objective of this study was to determine whether female victims of physical forms of intimate partner violence (IPV) displayed deficits in risk recognition, or the ability to detect danger, in physically violent dating encounters. A total of 182 women watched a video depicting a psychologically and physically aggressive encounter between…

Children and adolescents with aggressive and delinquent behaviours are often educated in special needs classes with others who exhibit the same kind of challenging behaviour. Beside the opportunities provided by this approach there are also risks, as several studies point to the problem of negative peer influence among this student population.…

This study examined the role of approval-of-aggression beliefs in the relationship between narcissistic exploitativeness and bullying behavior in an Asian sample (N = 809) comprising elementary children and middle school adolescents. Narcissistic exploitativeness was significantly and positively associated with both bullying behavior and…

Family conflict and childhood anxiety has been implicated in the development of aggressive behaviors, but the nature of these relationships has not been fully explored. Thus, the present study examined the role of anxiety in moderating the relationship between family conflict and childhood aggression in 50 children aged 7 to 13 years.…

The trauma of being a victim of sexual abuse is very difficult to live with, but for victims of internet offending there are added complexities for him/her in trying to make sense of what has happened. They are often "directed" by the offender to perform sexual acts on themselves and/or others, which creates huge confusion for the victim in terms…

Staff reactions play an important role in the development and maintaining of clients' challenging behaviour. Because there is a paucity of research on staff reactions in naturalistic settings, this study examined sequential associations between challenging behaviour and staff reactions by means of a descriptive analysis. We analysed video…

The role of conflict in parent-adolescent relationships is a topic of considerable theoretical debate and empirical investigation; however, limited attention has been devoted to the strategies used by family members to deal with disagreements and their outcomes and how they differ from early to late adolescence. This study explored conflict styles…

This study examined the dynamics of popularity in adolescent friendship networks across 3 years in middle school. Longitudinal social network modeling was used to identify selection and influence in the similarity of popularity among friends. It was argued that lower status adolescents strive to enhance their status through befriending higher…

Existing research suggests that there is a relation between academic/cognitive deficits and externalizing behavior in young children, but the direction of this relation is unclear. The present study tested competing models of the relation between academic/cognitive functioning and behavior problems during early childhood. Participants were 221…

Bullying is a continuing problem in schools, and can result in physical, psychological, and emotional harm to victims, as well as negatively affecting the school culture for students and teachers. Anti-bullying initiatives have typically focused on zero-tolerance strategies, but these have not been effective in promoting a positive school culture.…
