Exposure with and without cognitive therapy for generalized social phobia: effects of individual and group treatment.

Patients with generalized social phobia (n = 73) were randomly allocated to two treatment modalities: (1) group or (2) individual treatment, and to three treatment packages: (1) two blocks of exposure in vivo (2) a block cognitive therapy followed by a block exposure in vivo, or (3) two blocks cognitive-behavioural treatment in which both strategies were integrated from the start. All treatments consisted of 16 sessions, given in two treatment blocks of 4 weeks each, separated by a no-treatment phase of 4 weeks. Self-report assessments were held before and after the treatment blocks and at 3-months follow-up. Significant differences were found between effects of the first treatment block vs those of the 4-weeks waiting-list period. Repeated measures MANOVA's demonstrated significant time effects after both treatment blocks and at follow-up, indicating improvement for the group as a whole. After the first treatment block the integrated treatment did significantly worse than either exposure in vivo or cognitive therapy in decreasing somatic complaints. On the other variables no differences among the treatments were found. At follow-up a significant interaction was found between treatment package and modality on the variable cognitions: largest progress was found in the group treatment with cognitive therapy followed by exposure in vivo; smallest progress was found in the integrated group treatment. Results are discussed and recommendations for further research are given.
