Abstract
The development of a 2 l-item self-report inventory for measuring the severity of anxiety in psychia-ric populations i described. The initial item pool f86 items was drawn from three preexisting scales: the Anxiety Checklist, the Physician's Desk Reference Checklist, and the Situational Anxiety Checklist. A series of analyses was used to reduce the item pool. The resulting Beck Anxiety Inventory (BAI) is a 21-item scale that showed high internal consistency (a =.92) and test-retest reliability over 1 week, r(81) =.75. The BAI discriminated anxious diagnostic groups (panic disorder, generalized anxiety disorder, etc.) from nonanxious diagnostic groups (major depression, dysthymic disorder, etc). In addition, the BAI was moderately correlated with the revised Hamilton Anxiety Rating Scale, r(150) =.51, and was only mildly correlated with the revised Hamilton Depression Rating Scale, r(l 53) =.25. Studies addressing the distinctiveness of anxiety and depression depend on the availability of reliable and valid assessment instruments. However, a number of studies have reported high correlations (r>.50) between the widely used rating scales of anxiety and depression (e.g., Dobson, 1985; Mendels,
