Two hundred thirty-eight first-year college students were assessed using the Beck Depression Inventory (BDI). Thirty students meeting the BDI criteria for moderate to severe depression were randomly assigned to either a treatment or control group.
The treatment group received four 90-minute group sessions of EFT (Emotional Freedom Techniques), a novel treatment that combines exposure, cognitive reprocessing, and somatic stimulation. The control group received no treatment.
Post tests were conducted 3 weeks later on those that completed all requirements (N=18). The EFT group (n=9) had significantly more depression at baseline than the control group (n=9) (EFT BDI mean = 23.44, SD=2.1, versus control BDI mean = 20.33, SD=2.1).
After controlling for baseline BDI score, the EFT group had significantly less depression than the control group at posttest, with a mean score in the “nondepressed” range (P=0.001; EFT BDI mean = 6.08, SD=1.8 versus control BDI , mean = 18.04, SD=1.8). Cohen’s d was 2.28, indicating a very strong effect size.
These results are consistent with those noted in other studies of EFT that included an assessment for depression and indicate the clinical usefulness of EFT as a brief, cost-effective, and efficacious treatment.
