Developed by Aaron Beck as part of the Beck Scales to assist the clinician in making balanced and reliable assessments of patients. Test results are useful as a first step in detecting and proper treatment of an affective disorder. Gauges the severity of patient anxiety. It was intended to help differentiate between anxiety and depression by measuring anxiety symptoms shared minimally with those of depression. The test addresses physiological as well as cognitive elements of anxiety with a 21 question tool addressing subjective, somatic, or panic-related symptoms. Distinguishes between anxious and non-anxious groups in a variety of clinical settings and is appropriate for use with all adult mental health populations. In this test, subjects respond on the 21 items on a scale of 0-3. The test data are reported based on samples of patients diagnosed previously with Panic Disorder with Agoraphobia, Panic Disorder without Agoraphobia, Social Phobia, Obsessive-Compulsive Disorder, and Generalized Anxiety. The test is appropriate for individuals ages 17-80 and requires 5-10 minutes to administer.
