Interpersonal problem-solving skill has been identified as one subset of socially competent behavior which is highly correlated with, and predictive of, successful life adjustment. The present paper reviews the theoretical and research-based evidence underlying cognitive/behavioral interpersonal problem-solving training. Current assessment strategies, treatment techniques, and the methodological shortcomings in the existing literature are critically evaluated. The assessment and treatment implications which extend from the review are discussed and suggestions for future research directions are offered.
