The present paper provides an overview of the guiding theory and descriptive features of the cognitive-behavioral approach to psychosocial interventions for youths. Cognitive-behavioral treatment has been applied to various disorders including anxiety, aggression, depression, attention deficit-hyperactivity disorder, pain, and learning disabilities. Research on the nature of these disorders, a description of related treatment strategies, and an illustrative review of treatment outcome data is provided. Discussion focuses on a consideration of familial involvement, developmental factors, and methodological issues (i.e., comorbidity and normative comparisons) that require research attention. © 1995 Plenum Publishing Corporation.
