Bottom line. A 2025 meta-analysis (Zheng et al.) found EFT significantly reduced depression symptoms in cancer and serious-illness patients versus control (Mean Difference -7.41, 95% CI -9.32 to -5.51). Mean Difference is not standardized, so its magnitude depends on the symptom scale used.

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.
