Designing Interventions for Inner-City Aggressive Females

The major goal of this early career award is to examine the playground behavior, social cognitions, and comorbid conditions of subgroups of aggressive girls, and to establish an effect size estimate for the 20-session school-based group intervention to improve these high-risk girls' friendship making skills and anger management abilities.
