Demonstrated Efficacy of EFT To date, no randomized clinical trials have been conducted specifically using EFT in the treatment of disaster survivors. Nonetheless, the Foundation for Epigenetic Medicine has conducted several landmark studies on the use of EFT across a wide range of issues. One such study of 216 healthcare workers including doctors, nurses, chiropractors, and alternative medicine practitioners found that a brief EFT treatment produced 68% reductions in pain, 83% reductions in cravings, and 45% reductions in psychological problems such as anxiety and depression (all p < .001). Another study, a randomized controlled trial of veterans with PTSD, found that EFT reduced PTSD symptoms by 60% (p < .001). While many important EFT research questions remain to be answered, a great deal of groundwork is already in place including the two studies cited above. EFT has been researched in more than 10 countries, by more than 60 investigators, whose results have been published in more than 20 different peer-reviewed journals. These including distinguished top-tier journals such as Journal of Clinical Psychology, the APA journals Psychotherapy: Theory, Research, Practice, Training and Review of General Psychology and the oldest psychiatric journal in the US, the International Journal of Nervous and Mental Disease. EFT research includes investigators affiliated with many different institutions. In the US, these include Harvard Medical School, University of California at Berkeley, City University of New York, Walter Reed Army Medical Center (USUHS) and Texas A&M University. Institutions in other countries whose faculty have contributed to EFT research include Lund University (Sweden), Ankara University (Turkey), Santo Tomas University (Philippines), Lister Hospital (England), Cesar Vallejo University (Peru), and Griffith University (Australia). The wide variety of institutions, peer-reviewed journals, investigators, and settings that have, in independent research, found EFT to be efficacious, are one indication of the breadth of existing research results. The next frontier of EFT research is replication of the studies that have not yet been replicated, and investigations into the physiological changes that occur during EFT, using such tools as DNA microarrays (gene chips), MEGs (magneto encephalograms), fMRIs, and neurotransmitter and hormone assays.
