Datafile for meta-analysis on the efficacy of assertiveness training for social anxiety

This is the datafile for a meta-analysis. The meta-analysis synthesised research assessing the efficacy of assertiveness training for reducing social anxiety. A comprehensive search led to six relevant randomised control trials (RCTs) with a total of 298 participants. Meta-analysis using a random-effects model showed that assertiveness training was significantly more effective for reducing social anxiety than a wait-list control. The weighted meta-analytic effect size, g = 1.21, indicates a large positive effect. These results support the use of assertiveness training for persistent social anxiety.
