There’s extensive research on EFT which can be found on www.eftuniverse.com. At this site you can download a manual and register for a weekly newsletter from Dawson Church.
In 2010 Crystal co-ordinated a study being done by Church for American veterans. We offered 6 sessions of EFT with 3 and 6 month follow-ups for any veteran with clinically diagnosed PTSD. After 6 sessions 86% of the veterans no longer met the clinical criteria of PTSD. It was published in 2011 and last year the American Veterans Association stated that they would consider using EFT for veterans. Here’s a description of that Study.

Abstract: This study examined the effect of Emotional Freedom Techniques (EFT), a brief exposure therapy combining cognitive and somatic elements, on posttraumatic stress disorder (PTSD) and psychological distress symptoms in veterans receiving mental health services. Veterans meeting the clinical criteria for PTSD were randomized to EFT (n = 30) or standard of care wait list (SOC/WL; n = 29). The EFT intervention consisted of 6 hour-long EFT coaching sessions concurrent with standard care. The SOC/WL and EFT groups were compared pre- and post test (at 1 month for the SOC/WL group, after 6 sessions for EFT group). EFT subjects had significantly reduced psychological distress (p < .0012) and PTSD symptom levels (p < .0001) post test. In addition, 90% of the EFT group no longer met PTSD clinical criteria, compared with 4% in SOC/WL. Following the wait period, SOC/WL subjects received EFT. In a within-subjects longitudinal analysis, 60% no longer met PTSD clinical criteria after 3 sessions. This increased to 86% after 6 sessions for the 49 subjects who ultimately received EFT, and remained at 86% at 3-months and 80% at 6-months. The results are consistent with other published reports showing EFTs efficacy at treating PTSD and co-morbid symptoms and its long-term effects.
Crystal has also co-authored a study looking at the “Usefulness of EFT for Anxiety”. This was accepted at the Research Symposium of ACEP and was presented by Crystal at their conference in 2016. It’s not yet published.
