This study provides a meta-analytic review of controlled trials examining cognitive behavior therapy (CBT) and pharrnacotherapy for generalized anxiety disorder (GAD). Thirty-five studies, published or presented between 1974 and January 1996, were identified, and provided 61 separate treatment interventions. Both modalities of treatment offered clear efficacy to patients, and the overall effect size (ES) for CBT (ES = .70) was not statistically different from pharmacotherapy (ES = 0.60) for measures of anxiety severity. CBT was associated with significantly greater effects on depression severity, and was associated with clear maintenance of treatment gains, whereas the long-term efficacy of pharmacologic treatment was attenuated following medication discontinuation. Data concerning the efficacy of specific cognitive behavioral and pharmacologic interventions are provided, as are analyses of the influence of methodological factors (e.g., gender distribution, length of treatment) on the efficacy of treatments.
