Irrational beliefs and the anxiety disorders

This study investigated the levels of irrationality reported by a clinical sample of anxiety disorder patients, including simple and social phobics, panic disorder patients, agoraphobics, and obssessive compulsive patients. The levels of irrationality were compared between these groups and a group of normal control subjects, using the Rational Behavior Inventory (RBI). Agoraphobic patients were significantly less rational than control subjects on six of the RBI's subfactors and the total score of the Inventory. Patients in all diagnostic categories except simple phobia were significantly different from control subjects on the projected misfortune subfactor, and patients in all categories except simple phobia and panic disorder were significantly different from controls on the total RBI score. There were only four instances where patients in anxiety disorder categories significantly differed from each other in levels of irrationality. The implications of these findings, methodological limitations, and directions for future research are discussed.Joseph A.
