Exposure versus cognitive restructuring in the treatment of panic disorder with agoraphobia

The aim of this study was to assess the rate of change on clinical, behavioral and cognitive variables during exposure therapy and cognitive restructuring in the treatment of panic disorder with agoraphobia. A total of 28 Ss who received a diagnosis of panic disorder with agoraphobia were randomly assigned to either of two treatment conditions: exposure therapy or cognitive restructuring. Treatment conditions were kept as distinct as possible from each other. Subjects were assessed on five occasions: pretreatment, after 5, 10, and 15 (posttreatment) sessions of treatment and at a 6-month follow-up. Analyses of outcome data revealed strong and significant time effects on all measures. However, no group × time interaction reached statistical significance, suggesting that both strategies operate at the same pace. Furthermore, power analyses suggest that any difference that might exist in the rate of improvement between exposure and cognitive restructuring in the treatment of panic disorder with agoraphobia is marginal.
