This meta-analysis investigated the effectiveness of group programs designed to reduce counselor burnout in South Korea. Fourteen studies published between 2011 and August 2025 were included, resulting in 50 effect sizes for analysis. The overall mean effect size was 1.12, indicating a large impact. Moderator analyses revealed that interventions were most effective in groups of ten or fewer participants, held three or more times per week, lasting under 90 minutes per session, with no homework assigned, including session reflections, and when the program type was group counseling. Both face-to-face and online formats proved effective. Large effect sizes were consistently observed across measurement tools (MBI and K-CBI), reinforcing the uniformity of burnout definition and assessment. Follow-up effects remained stable from post-intervention (1.14) to four weeks later (1.13). Based on these findings, implications for program development and future research directions are discussed.
