Remediation and Prevention of Aggression: An Evaluation of the Regional Intervention Program Over a Quarter Century

This article presents an overview of the Regional Intervention Program (RIP) and describes ongoing studies to examine the long-term effects of behavioral skill training for parents of preschool children who engaged in severe forms of aggression and antisocial behavior. The results of evaluation studies on RIP clients have shown that (a) the initial intervention experience yields predictable and replicable outcomes for adults and children; (b) outcomes for children and adult clients maintain for periods ranging from 3 to 9 years, based on direct observational assessments in school and home settings; (c) these intermediate follow-up results are strongly influenced by early enrollment in the program, with children who began at the earliest ages experiencing more favorable outcomes; (d) the 3- to 9-year follow-up results for home-based observation are replicable across clients who received treatment from an entirely different intervention staff; (e) adolescent and adult outcomes indicate long-term maintenance of intervention gains; and (f) former adult consumers consider RIP intervention strategies to be highly acceptable.
