On Gary Craig’s EFT (Emotional Freedom Technique) website he has a series of articles referring to the “Scientific Evolution of EFT from TFT”.  These were first published in the late 1990's.

To anyone fully trained in TFT and conversant with Roger's (Dr Roger Callahan) theory, it should be abundantly clear that the articles are full of factual and deductive errors.

Ian Graham, theHonorary President – British Thought Field Therapy Association put together a response that sought to correct the errors and asked Gary Craig a number of times to publish his reply alongside his own article so that the general public could read an alternative explanation and therefore make a choice based on full, accurate and reliable information.

He has always declined to do so.

Thought Field Therapy Is Proven Efficacious:
Why the Critics Are Wrong About TFT-By Steven Barger, Independent Scholar
This paper is in response to the October 2001 Journal of Clinical Psychology (JCLP) issue, devoted to the topic of Thought Field Therapy. After reading all the articles, I felt it necessary to respond in detail to objections I had to the critics' articles including: numerous critical reasoning errors, misunderstandings of the actual claims for TFT, several straw-man arguments, a false a priori assumption, arguments from false premises, and citing of references that, when checked, are found to not at all support the specific point being made, by the critic. One critic even cites an article he co-authored that actually contradicts the point he's making, and instead supports a significant point made by TFT proponents! Read the article

The Association for Thought Field Therapy Foundation is a non-profit membership
organization whose volunteers provide psychological help to people traumatized by wars, natural disasters, genocide and
poverty.

The group’s Trauma Relief Teams, including psychologists, counsellors, doctors, and social workers, are trained in the
Callahan Technique of Thought Field Therapy (TFT).

They have assisted trauma
victims in many parts of the world, including New Orleans and Mississippi in the aftermath of the Hurricane Katrina
disaster; Tabasco and Chiapas, Mexico, after major flooding there; and in Kosovo, the Congo, and Rwanda to treat
genocide survivors.

Caroline Sakai, PhD., a psychologist and TFT practitioner, based in Hawaii,
headed a team of therapists who worked with children in an orphanage in Kigali, Rwanda.

The children survived the
Rwandan genocide in 1994, in which 800,000 to 1 million people were slaughtered
during the course of 100 days. Dr Sakai was interviewed by Michiko Ishikawa for Share International. Read more:
