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 o f self-reported anxiety and depression, the authors administered the B eck 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 transform ation, indicated that the amounts of extracted variance and symptom co mpositions of the resultant factors were comparable to those found in the previous study. The results from both studies are discussed as sup porting the tripartite (L. A. Clark and D. Watson, 1991) and cognitive -specificity (A. T. Beck, 1976, 1987) models of anxiety and depression .
