ResumoTraditionally, psychotherapy outcome research has been analyzed using statistical tests of significance. Inherent limitations in this approach, however, have contributed to the assessment of clinical significance being advocated as a method by which to evaluate change. In this study, Tingey, et al, 1996a, Tingey, et al, 1996b extensions and clarifications of Jacobson, Follette, and Revenstorf's (1984) method for evaluating clinically significant change were applied to the Beck Depression Inventory (BDI; Beck, Ward, Mendelson, Mock, & Erbaugh, 1961; Beck, Rush, Shaw, & Emery, 1979). A three-sample normative continuum (asymptomatic community, community, and clinically symptomatic) was formulated from the community and the existing literature. The distinctness of the normative samples was assessed by using three statistical procedures, including a t test, a d test, and a test of bioequivalence; and reliable change indices and cutoff points were calculated. The cutoff scores that were developed may prove useful in research and clinical practice.
