Further evidence for the validity of the beck anxiety inventory with psychiatric outpatients
The Beck Anxiety Inventory (BAI) was administered to 470 outpatients (284 women and 186 men) with mixed psychiatric disorders along with the revised Beck Depression Inventory (BDI) and the SCL-90—R. The BAI's internal consistency was high and it was significantly more correlated with the SCL-90—R Anxiety subscale than it was with SCL-90—R Depression subscale. However, it was also significantly correlated with the BDI. The mean BAI scores of the 141 (30.0%) outpatients with mood disorders and the 86 (18.3%) outpatients with anxiety disorders were comparable, but higher than the mean BAI score of the 243 (51.7%) outpatients with other disorders. A principal components analysis found subjective, neurophysiological, panic, and autonomic dimensions.
