The utility of the Fear Survey Schedule-III: an extended replication.

This investigation examined the factor structure of the Fear Survey Schedule-III in patients with specific anxiety disorders, including patients with panic disorder, agoraphobia without panic, generalized anxiety disorder, social phobia, specific phobia, obsessive compulsive disorder, post traumatic stress disorder, and anxiety disorder NOS. Four factors were obtained, reflecting a similar structure as has been noted in other studies. However, the ability of the obtained factors to discriminate among patients with panic disorder, social phobia, and specific phobia was not high. Future directions are highlighted.
