 Another study indicates that, in primary care patients with different anxiety disorders including social phobia, panic disorder, panic disorder with or without agoraphobia, agoraphobia, or generalized anxiety disorder, the BAI seemed to measure the severity of depression.This suggests that perhaps the BAI cannot adequately differentiate between depression and anxiety in a primary care population.In a study examining the BAI's use on older adults with generalized anxiety disorder, no discriminant validity was seen between the BAI and measures of depression.
