Panic disorder: A cognitive-behavioural approach to treatment

The present study investigated the relationship between panic disorder and cognitive-behavioural therapy in a sample of 27 panic disorder patients who were randomly assigned to either a Treatment (six weeks of cognitive-behavioural therapy) or a Control group. Panic disorder was operationalized using three subjective and three physiologic indices. Results indicated that six weeks of cognitive-behavioural therapy were effective in decreasing panic disorder, as measured by three report measures: the Anxiety Sensitivity Index (catastrophic thoughts), State-Trait Anxiety Inventory (trait anxiety), and number of panic attacks, for the Treatment group relative to the Control group. In contrast, cognitive—behavioural therapy was ineffective in decreasing physiologic arousal as defined by blood pressure, pulse rate, and finger temperature. Implications of these results are discussed.
