A critical review of psychotherapy outcome studies with adolescents: 1978-1988.

Although interest in identifying effective psychotherapies for adolescent mental health problems has increased dramatically in the last decade, there have been few attempts to summarize and integrate the recent empirical literature on psychotherapy outcomes with adolescents. The present paper reviews the methods and findings of adolescent psychotherapy outcome studies published from 1978 to 1988. Evaluations of individual psychotherapy with adolescents generally reveal positive short-term outcomes, but long-term outcomes are still to be determined. Evaluations of systemic therapies (especially family therapy) with adolescents often reveal positive outcomes that are maintained over extended follow-up periods. Recommendations are presented for improving the methodology of future psychotherapy outcome studies with adolescents.
