Demonstration of efficacy must satisfy not only clinicians, but increasingly policy makers and the public at large as well. Treatments not fitting a narrow biomedical approach to therapeutics are especially suspect. It is imperative that clinicians and clinical trainees become experts not only in the theory and application of psychotherapy, but also about research bearing on the efficacy question and the theoretical and methodological issues relevant to this debate. This chapter provides a review of the data base for judging psychotherapy efficacy, and related concepts and special problems are also discussed.
