Ra. Steer et al., COMMON AND SPECIFIC DIMENSIONS OF SELF-REPORTED ANXIETY AND DEPRESSION - A REPLICATION, Journal of abnormal psychology, 104(3), 1995, pp. 542-545
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
.
