The efficacy of videotape feedback for enhancing the effects of exposure-based treatment for social anxiety disorder: a controlled investigation.

Correcting patients' faulty beliefs concerning social evaluative threats is the hallmark of cognitive-behavioral treatment of social anxiety disorder. The current study examined the efficacy of two videotape feedback procedures as adjuncts to exposure-based treatment. Participants suffering from social phobia (N=77) were randomly assigned to one of four conditions: (a) credible placebo treatment (PLA); (b) exposure + no feedback (EXP); (c) exposure + videotape feedback of performance (PER); or (d) exposure + videotape feedback of audience responses (AUD). Contrary to prediction, the videotape feedback procedures did not enhance the effects of exposure-based treatment. Clinical and theoretical implications are discussed.
