A component analysis of cognitive-behavioral treatment for depression . The purpose of this study was to provide an experimental test of the theory of change put forth by A. T. Beck , A. J . Rush , B. F. Shaw , and G. Emery ( 1979 ) to explain the efficacy of cognitive-behavioral therapy ( CT ) for depression . The comparison involved randomly assigning 150 outpatients with major depression to a treatment focused exclusively on the behavioral activation ( BA ) component of CT , a treatment that included both BA and the teaching of skills to modify automatic thoughts ( AT ) , but excluding the components of CT focused on core schema , or the full CT treatment . Four experienced cognitive therapists conducted all treatments . Despite excellent adherence to treatment protocols by the therapists , a clear bias favoring CT , and the competent performance of CT , there was no evidence that the complete treatment produced better outcomes , at either the termination of acute treatment or the 6-month follow-up , than either component treatment . Furthermore , both BA and AT treatments were just as effective as CT at altering negative thinking as well as dysfunctional attributional styles . Finally , attributional style was highly predictive of both short- and long-term outcomes in the BA condition , but not in the CT condition .
