Thought Field Therapy (TFT) was founded by psychologist Roger Callahan. It was formerly known as the 'Callahan Techniques'.
NOTE: The main difference bewteen Emotional Freedom Technique (EFT) and Thought Field Therapy (TFT) is that EFT taps on the alleged main meridian points in no particular sequence, whereas with TFT, sequence is critical to treatment success.

"Devilly (2005 p.444) states that there is no evidence for the claimed efficacy of power therapies such as TFT (and others such as NLP and they exhibit the characteristics of a pseudoscience. Lilienfeld, Lynn & Lohr (2003, Chapter 1) also use TFT as an example of a therapy that contains some of the hallmark indicators of a pseudoscience. Specifically, they note its evasion of the peer review system and absence of boundary conditions. Additionally, Pignotti (2004) has noted its use of obscurantist jargon (scientific-sounding terms such as thought fields, and perturbation that have no basis in evidence) and Callahan's using the idea of energy toxins to explain away treatment failures."

Monica Pignotti describes her 7-year experience as a leading practitioner, author, and teacher of thought field therapy (TFT). Her lengthy story describes (a) what initially interested her, (b) how she trained to TFT's highest level became part of its inner circle and (c) what led to her ultimate disillusionment. Research on Social Work Practice (17:392-407 2007) [ABSTRACT]
"Much of the coverage of TFT in the media has been insufficiently critical, largely because it has not emphasized the limited database concerning TFT's efficacy. Instead, unsupported claims for efficacy have been made based mostly on anecdotes and have not typically been challenged."
