Group climate as predictor of short- and long-term outcome in group therapy for social phobia.

A longitudinal study of 80 participants in cognitive and interpersonal group therapy for social phobia was conducted. The aim was to investigate the relationship between group climate and patients' short-term and long-term outcome. Group climate data was collected every other week during treatment, whereas social phobia symptoms were assessed at admission, discharge, and one year follow-up. Abbreviated symptom assessments were performed weekly. Regression analyses and mixed models were used in the analyses. Engagement predicted symptom reduction during treatment, from pretreatment to follow-up, and from posttreatment to follow-up. During treatment, avoidance predicted higher symptomatic distress. The results imply that group engagement should be emphasized for patients with social phobia. Avoidance, on the other hand, should be addressed as a process that interferes with treatment progress.
