A Meta-Analysis of Randomised Controlled Trials on the Efficacy of Assertiveness Training for Social Anxiety
摘要
Social anxiety (SA) is a prevalent mental health condition with adverse impacts across multiple social domains; nonetheless, many individuals who experience SA are reluctant to seek help. As a positive-psychology approach that focuses on building interpersonal skills rather than on symptom reduction, assertiveness training (AT) may reduce barriers to treatment for people inhibited by stigma associated with psychotherapy. The researchers searched five databases: EBSCO, Embase, ProQuest, PubMed, and Scopus for “social anxiety” OR “social phobia” OR SAD) AND (“assertiveness training” OR “assertive training” OR assertive*) AND random* OR RCT). The reference lists of included studies were also searched for other applicable RCTs. In addition, Google Scholar’s “cited by” and “relevant articles” functions were used for included studies to search for additional relevant research. This meta-analysis synthesised data from 12 randomised controlled trials, with a total of 503 participants, investigating the use of AT for SA in a variety of contexts and settings. The significant overall effect size was medium, g = 0.62, 95% CI [0.32, 0.92], p < .001, with no evidence of publication bias. Moderator analyses of gender, intervention length, and global region were non-significant and did not explain the moderate heterogeneity observed across studies. The overall results suggest that AT tends to be an effective intervention for SA and thus provides a positive-psychology option for intervention.
