Reviews psychosocial interventions for child and adolescent conduct problems, including oppositional defiant disorder and conduct disorder, to identify empirically supported treatments. Eighty-two controlled research studies were evaluated using the criteria developed by the Division 12 (Clinical Psychology) Task Force on Promotion and Dissemination of Psychological Procedures. The 82 studies were also examined for specific participant, treatment, and methodological characteristics to describe the treatment literature for child and adolescent conduct problems. Two interventions were identified that met the stringent criteria for well-established treatments: videotape modeling parent training program (Spaccarelli, Cotler, & Penman, 1992; Webster-Stratton, 1984, 1994) and parent-training programs based on Patterson and Gullion's (1968) manual Living With Children (Alexander & Parsons, 1973; Bernal, Klinnert, & Schultz, 1980; Wiltz & Patterson, 1974). Twenty of the 82 studies were identified as supporting the efficacy of probably efficacious treatments.
