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 tapping vs. a comparison group; d ≥ 0.8 is considered large. 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.
