Purpose: This study examines the effects of the career group counseling program implemented in Korea for college students, focusing on career identity, and analyzes the effects using meta-analysis methods. Methods: Search for relevant articles included several electronic databases and hand-search from article references. 24 studies met inclusion criteria from 1,016 studies. R program package ‘meta and meta for’ were used to analyze effect sizes, investigate possible causes of heterogeneity and check publication bias. Results: The overall mean effect size of the career group counseling program for college students was large(Hedges’ g=1.67, 95% CI [1.14, 2.21]) and heterogeneity was considerable(Q=162.82, df=23, p<.001, I 2=85.9%). Meta-regression and meta-ANOVA were performed to estimate causes of heterogeneity. As a result of the analysis of the modulating effect, 9-11 sessions(g=2.08, 95% CI [1.25, 2.91]), 900-1,100 minutes(g=2.05, 95% CI [0.77, 3.32]), Career counseling(g=2.16, 95% CI [1.40, 2.93]) and Self understanding(g=1.89, 95% CI [0.53, 3.25]) showed the largest effect size. Finally, a funnel plot, trim-and-fill analysis and Egger’s regression test were performed to check for publication bias, but no significant bias was detected. Conclusion: Based on these results, The career group counseling program implemented for college students is considered to be an effective intervention for change of career identity. The analysis results of this study can be used as evidence-based data for the development and application of career identity improvement programs for college students.
