Common and specific dimensions of self-reported anxiety and depression: A replication.

To investigate the generalizability of D. A. Clark, R. A. Steer, and A. T. Beck's (1994) findings about the common and specific dimensions of self-reported anxiety and depression, the authors administered the Beck Depression and Anxiety Inventories to 1,000 outpatients diagnosed with various types of psychiatric disorders. Iterated principal-factor analyses with oblique rotation, followed by a Schmid-Leiman transformation, indicated that the amounts of extracted variance and symptom compositions of the resultant factors were comparable to those found in the previous study. The results from both studies are discussed as supporting the tripartite (L. A. Clark & D. Watson, 1991) and cognitive-specificity (A. T. Beck, 1976, 1987) models of anxiety and depression.
