ABSTRACT
In recent years, while the violent crime arrest rate has decreased for boys, it has increased for girls. Anger-related behaviors, such as physical and relational aggression, account for a significant proportion of the crimes for which these youth are arrested. Nevertheless, there exists no empirically evaluated anger management intervention designed specifically for a female juvenile offender population. This pilot study is a first step in developing such an intervention. Participants were 12 girls in a post-adjudication facility who were randomly assigned to either the 18- session anger management treatment condition or the treatment-as-usual control condition. Although significant differences between the groups on measures of anger and aggression were difficult to detect because of the pilot study's small sample size, medium- to large-effect sizes were obtained. These findings suggest promise for a larger-scale efficacy study. Further revisions to the treatment manual for the larger-scale efficacy study are discussed.
