Youth in a program designed to increase adolescent perspective taking, social problem-solving and conflict management skills displayed lower levels of disruptive behavior and were less aggressive than control group members. The Anger Coping Program (Lochman, 1985, 1992; Lochman, Burch, Curry, & Lampron, 1984) is a school-based program designed to decrease conduct problems, delinquency, and substance abuse in adolescent boys. Fifty-two 10-year-old boys were randomly assigned to one of four conditions: 1) anger coping, 2) goal setting, 3) combined group, and 4) control group. Boys in the treatment conditions displayed lower rates of disruptive behavior in classroom observations compared to the control group boys. Compared to the controls, parents rated boys in the treatment conditions as less aggressive during conflicts. These effects were greatest for the combined treatment group than for either treatment alone.
