This chapter will discuss cognitive-behavioral therapy for anger and aggression in youth, focusing on the Coping Power Program. The contextual social-cognitive model of anger and aggression as well as a variety of risk factors will be discussed, which present a conceptual framework for the Coping Power Program. An overview of other CBT programs for anger and aggression in youth will be presented, followed by a detailed description of the Coping Power intervention, including sample dialogue and handouts. The Coping Power Program was originally developed for late elementary to early middle school children and includes both a child and a parent component, addresses topics including children’s emotion awareness, ability to cope with anger and frustration, and social problem-solving skills, as well as parenting skills related to building positive family relationships and managing children’s behavior. Additionally, a number of adaptations have examined the Coping Power Program with individuals instead of groups, upwardly and downwardly extended age groups, altered intervention length, and different settings, indicating that the intervention can be flexibly applied. Research on Coping Power’s efficacy and effectiveness will be discussed, followed by implications for dissemination and optimization of the intervention.
