A substantial number of strong studies have established the efficacy of cognitive-behavioral treatment for persons with panic disorder with or without agoraphobia. These treatments include some combination of cognitive elements, exposure to interoceptive sensations similar to physiological panic sensations, in vivo exposure, and breathing retraining. A number of excellent studies have established the clinical efficacy of situational in vivo exposure for patients with moderate to severe agoraphobia and specific phobia. The most common treatment approaches for social anxiety disorder include social skills training, relaxation techniques, exposure-based treatment methods, and multicomponent cognitive-behavioral treatments.
