A Systematic Review and Meta-Analysis of the Effectiveness of Non-Face-to-Face Coaching

Abstract

This study examined the effectiveness of non-face-to-face coaching in South Korea in order to present alternatives in the post-COVID-19 environment. The research collected domestic studies on non-face-to-face coaching in South Korea and analysed the studies through a systematic literature review and meta-analysis. Among 1081 papers retrieved from the database, we selected ten papers for meta-analysis. Using the random effect model to measure effect size, the total effect size of non-face-to-face coaching was 0.77. When we divided the effect of non-face-to-face coaching into psychological, cognitive, and physical effects, the cognitive effects were the largest. In addition, examining non-face-to-face coaching by type resulted in a larger effect size of web-based online coaching in comparison to telephone coaching. By contrast, the effect sizes of non-face-to-face coaching by subject had the largest effect size on subjects with the highest level of vulnerability. This study found that non-face-to-face coaching had a large effect, with relatively large cognitive and psychological effects. Future investigations should supplement the present research through follow-up studies on non-face-to-face coaching.
