A number of social skill training approaches have been devised for remediating peer relationship difficulties in children and adolescents. One recently developed approach, focusing on interpersonal cognitive problem solving (ICPS) skills, is described. ICPS training studies are also reviewed. Despite the pervasive methodological problems that characterize this literature, ICPS training appears to be effective as a remediation strategy with maladjusted youngsters, and as a secondary prevention strategy with children 'at risk'. While initial findings with nonclinical groups have been less encouraging, available follow-up data suggest that ICPS training may be efficacious as a primary prevention strategy, as well. Several suggestions are offered for improving the methodology of future training studies, while important issues and problems are highlighted for future investigation.
