Abstract
In a controlled clinical trial, 57 Ss meeting DSM-III-R criteria for generalized anxiety disorder, and fulfilling an additional severity criterion, were randomly allocated to cognitive behavior therapy (CBT), behavior therapy (BT), or a waiting-list control group. Individual treatment lasted 4-12 sessions; independent assessments were made before treatment, after treatment, and 6 months later, and additional follow-up data were collected after an interval of approximately 18 months. Results show a clear advantage for CBT over BT. A consistent pattern of change favoring CBT was evident in measures of anxiety, depression, and cognition. Ss were lost from the BT group, but there was no attrition from the CBT group. Treatment integrity was double-checked in England and in Holland, and special efforts were made to reduce error variance. Possible explanations for the superiority of CBT are discussed.Keywords
