Aggression Replacement Training[R] (ART) is a psychoeducational approach to working with young people who experience difficulties with interpersonal relationships and prosocial behavior. ART[R] originated with Skillstreaming and developed into a three-component model. Arnold P. Goldstein recognized that the complex problems of youth would not yield to simplistic narrow approaches. Instead, he formulated a three-part multi-modal approach to problems in behavior, emotions, and thinking: (1) "Skillstreaming" targets social skills and behavior; (2) "Anger Control" training focuses on regulation of emotions; and (3) "Moral Reasoning" focuses on values and cognitions. ART[R] explicitly teaches an array of prosocial psychological skills to youth who have specified areas of need. Training is developed in a series of structured learning groups where youth are: (1) shown examples of expert use of the behaviors that constitute the skills in which they are deficient (i.e., modeling); (2) given guided opportunities to practice and rehearse these competent behaviors (i.e., role playing, self-talk); (3) provided with reinforcement, reinstruction, and performance feedback on how well they performed their role playing enactment; and (4) encouraged to engage in a series of activities designed to increase the chances that the skills learned in the training setting will endure and transfer to their home, school, community, and other real-world settings. Through the infusion of ART[R] with families and their children through programs like the Perseus House, Inc.'s Collaborative Intensive Community Treatment Program and Batshaw Youth and Family Centres' Family TIES (Teaching In Essential Skills) program, competency development and problem solving are increased and therefore more resilient families are created.
