EFT has been around for over 20 years now, and so there is a reasonable body of research testing how effective it is. Here are two pieces of research:

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.
The effect of emotional freedom techniques on stress biochemistry: a randomized controlled
Foundation for Epigenetic Medicine, Fulton, CA 95439, USA.
This study examined the changes in cortisol levels and psychological distress symptoms of 83 nonclinical subjects receiving a single hour long intervention. Subjects were randomly assigned to either an emotional freedom technique (EFT) group, a psychotherapy group receiving a supportive interviews (SI), or a no treatment (NT) group. Salivary cortisol assays were performed immediately before and 30 minutes after the intervention. Psychological distress symptoms were assessed using the symptom assessment-45. The EFT group showed statistically significant improvements in anxiety (-58.34%, p < 0.05), depression (-49.33%, p < 0.002), the overall severity of symptoms (-50.5%, p < 0.001), and symptom breadth (-41.93%, p < 0.001). The EFT group experienced a significant decrease in cortisol level (-24.39%; SE, 2.62) compared with the decrease observed in the SI (-14.25%; SE, 2.61) and NT (-14.44%; SE, 2.67) groups (p < 0.03). The decrease in cortisol levels in the EFT group mirrored the observed improvement in psychological distress.[/b]
