Effectiveness of Training for Cancer Support Group Facilitators: Five-year Outcomes from a National Program Commissioned by the Ministry of Health, Labour and Welfare

Abstract

Objective: To evaluate the effectiveness of a training program for cancer support group facilitators. Methods: From 2020 to 2024, 583 healthcare providers from designated cancer care hospitals nationwide participated. Effects were assessed at pre-training, immediately post-training, and 6 months post-training. Primary outcomes included overall training evaluation (10 items); secondary outcomes measured facilitation skills (8 items). Results: All 10 primary outcome items showed statistically significant improvements, with large effect sizes for “understanding of facilitator role” (η²_p=0.52) and “understanding of collaboration methods with peer supporters” (η²_p=0.63). The average 6-month retention rate was 44.8%. Several facilitation skills demonstrated significant improvements. No significant differences were observed by participation format. Occupational group analysis revealed small but significant differences at 6 months, primarily between medical social workers and other health professionals. Conclusion: This training is effective in improving understanding of cancer support groups, collaboration with peer supporters, and facilitation skills. Establishing continuous support systems to sustain training effects remains a future challenge.
