This article is a retraction of the conclusions drawn in a previous article, published as part of a special October 2001 issue of the Journal of Clinical Psychology on Thought Field Therapy (TFT). I decided to write this retraction after reconsidering a number of issues raised in the critiques of the articles. Additionally, subsequent misinterpretations of the literature on heart rate variability (HRV) by Roger Callahan, which led to further questioning of his premises and claims regarding TFT and HRV as represented in the articles, are discussed. I conclude that the burden of proof is on TFT proponents to demonstrate its efficacy and that well-designed controlled studies using standardized assessment measures and long-term follow-up must be performed to allow the scientific community to take claims made for TFT seriously.
