Factors affecting treatment efficacy in social phobia: The use of video feedback and individual vs. group formats

Research output: Contribution to journalReview articlepeer-review

Abstract

This meta-analysis assessed two potential moderators of treatment efficacy in social phobia: video feedback, and treatment format (i.e., individual vs. group). Eighteen recent (2000-2006) trials including a total of 511 participants were sampled. Effect sizes (Cohen's d's) were calculated for each trial while correcting for measurement error. The Q statistic was used to test (a) heterogeneity across trials and (b) potential moderators. Results indicated that use of video feedback was not a moderator of treatment efficacy and did not significantly affect effect sizes. In contrast, treatment format was a moderator of treatment efficacy such that individual treatments reported larger effect sizes and lower attrition rates compared with group treatments. The results suggest that individual treatments in social phobia may be superior to group treatments irrespective of treatment type.
