Bottom line. A 2024 meta-analysis (Seok & Kim, 18 RCTs) reported a large pooled effect on depressive symptoms versus control (Hedges' g = 1.268, 95% CI 0.951-1.585). Most included trials studied subthreshold or subclinical depression rather than diagnosed major depression, and roughly two-thirds carried some or high risk of bias — worth weighing before extending the finding to clinical populations.

What Tapping (EFT) is. A brief self-administered technique combining exposure and cognitive elements with fingertip stimulation of acupressure points. It is used as a self-help and adjunctive practice for stress and emotional regulation. Effect sizes above are reported as each study gives them: randomized and controlled trials give tapping versus a comparison group, while meta-analyses give pooled estimates — between-group versus control, or within-group pre-post where the row is labelled that way. For standardized effects (d, g), ≥ 0.8 is considered large; a Mean Difference is on the symptom scale's own units, not standardized. Limitations across this literature include variable use of active vs. waitlist controls and reliance on self-report measures. This summary is informational and not a substitute for clinical judgment.
