The Journal of Nervous and Mental Disease: June 2011 - Volume 199 - Issue 6 - p 372-378 doi: 10.1097/NMD.0b013e31821cd262 Buy Metrics Abstract The present study reports on the first ever controlled comparison between eye movement desensitization and reprocessing (EMDR) and emotional freedom techniques (EFT) for posttraumatic stress disorder. A total of 46 participants were randomized to either EMDR (n = 23) or EFT (n = 23). The participants were assessed at baseline and then reassessed after an 8-week waiting period. Two further blind assessments were conducted at posttreatment and 3-months follow-up. Overall, the results indicated that both interventions produced significant therapeutic gains at posttreatment and follow-up in an equal number of sessions. Similar treatment effect sizes were observed in both treatment groups. Regarding clinical significant changes, a slightly higher proportion of patients in the EMDR group produced substantial clinical changes compared with the EFT group. Given the speculative nature of the theoretical basis of EFT, a dismantling study on the active ingredients of EFT should be subject to future research. © 2011 Lippincott Williams & Wilkins, Inc.
