Empirically Documenting Clinically Significant Change in Rational Emotive Behavior Therapy

Abstract

The purpose of the present article is to outline the conceptual foundation and practical methodology of the Jacobson-Truax Clinically Significant Change index, derived from psychotherapy outcome research. This way of considering what constitutes clinically significant change in psychotherapy puts a premium on social validation. It empowers clinicians to evaluate the meaningfulness of their client's progress and to communicate that progress to third parties such as other clinicians, researchers, and insurers. Application of the method is demonstrated in the case of a client treated with Rational Emotive Behavior Therapy (REBT). The discussion focuses on the advantages of this procedure for satisfying the intellectual interest of the practitioner-scientist and for furthering informed discussion of the value in various applications of REBT to clinical problems.
