The current status of EFT as an "evidence-based" practice is summarized in this statement in the APA (American Psychological Association) journal Review of General Psychology:

'A literature search identified 50 peer-reviewed papers that report or investigate clinical outcomes following the tapping of acupuncture points to address psychological issues. The 17 randomized controlled trials in this sample were critically evaluated for design quality, leading to the conclusion that they consistently demonstrated strong effect sizes and other statistical results that far exceed chance after relatively few treatment sessions. Criteria for evidence-based treatments proposed by Division 12 of the American Psychological Association were also applied and found to be met for a number of conditions, including PTSD.'
