Purpose: This study was a meta-analysis planned to exam effects of enneagram group program for Korean university students. Methods: Search for relevant articles included several electronic databases and hand-search from article references. 14 studies and 29 effect variables met inclusion criteria from 107 studies. R with the ‘meta’ package was used to analyze effect sizes, investigate possible causes of heterogeneity and check publication bias. Results: Overall effect size of enneagram group program for university students was medium(Hedges’g=0.70, 95%CI:0.50-0.90) and medium heterogeneity(Q=95.92, df=28, P<.001; I2=71%). Meta-regression and meta-anova were performed to estimate causes of heterogeneity. As a result of the analysis of the modulating effect, there was no statistically significant difference between the self variable(g=0.68, 95% CI: 0.40-0.96) and the adaptation variable(g=0.73, 95% CI: 0.44-1.03), but the effect size was medium. 7-8 sessions(g=0.78, 95% CI: 0.78-0.57) and 1050-1200minutes(g=1.14, 95% CI: 0.71-1.57) showed the largest effect size. Finally, a funnel plot, Egger’s regression test and trim-and-fill analysis were performed to check for publication bias, but no significant bias was detected. Conclusion: Based on these results, the enneagram group program for Korean university students can be considered to have an important effect on improving psychological and social adaptability.
