Technique Explained


Thought Field Therapy® (TFT) is a technique for the rapid relief of all kinds of emotional distress. It works rather like acupuncture by stimulating the body’s energy meridians to resolve problems with the body’s emotional control system. However, no needles are used. Instead the patient taps on various parts of the upper body, face and hand with their fingers. The results are frequently startling as emotional problems often disappear in minutes.

Thought Field Therapy® (TFT) was originally developed as a treatment for phobias and traumatic stress. Further research has meant that it can now be used to treat a wide variety of problems including stress and anxiety, panic attacks, depression, OCD, grief, acute trauma and PTSD, anger, guilt, pain, addictions and much more.


According to Dr. Callahan’s theory, whenever we think of something, we are tuning in a specific “Thought Field” in much the same way as a TV must be tuned in to receive a specific channel. Held within that energy field are the coded information patterns, essentially, a set of inbuilt programmes used by the mind and body to generate the entire emotional experience associated with that thought.

This is why the experience (of fear, for example) is identical in all humans, therefore the same “instructions” are followed each time. Dr. Callahan has named these information patterns “perturbations” defined as a cause of mental disquietude.

By tapping on the correct accupuncture points in a specific sequence - as a developer writes delete instructions -these perturbations - which are isolatable and are the “root cause” of all negative emotions - can be deactivated, thereby effectively “switching off” the emotional experience. Thought Field Therapy® goes directly to the root cause of all psychological problems, and therefore, the cure - defined as the complete absence of any upset and distress as reported by the client – is proven to be the normal result of this treatment.

The individual can now think of the troubled situation as much as they like as memory remains unaffected, but the associated negative emotion (anxiety, guilt, anger, etc.) is no longer present.


The success of a treatment is based on improvement to the Subjective Units of Distress (SUD) Scale. TFT’s success rate depends on the experience and competence of the practitioner.
Algorithm Practitioner
Uses pre-defined sets of tapping sequences (Algorithms) to treat emotional distress.
 Success Rate : 80%
Diagnostic Practitioner
Uses techniques derived from Applied
Kinesiology to devise a specific tapping sequence. He may also check for various “toxins” which can affect your health and/or prevent TFT from working.
  Success Rate : 94%
Optimal Health Practitioner (formerly Voice Technology)
Analyses your voice using special technology to devise a specific tapping sequence.
Success Rate : 97%
Some therapies have never been able to publish success rates. Like with all therapies, no guarantee of total success can ever be made in any individual case.


Heart Rate Variability HRV is now being used by some practitioners to measure and show the state of a person’s Autonomic Nervous System (ANS) before and after Thought Field Therapy® treatment. In this way its dramatic effect in re-balancing and adjusting the ANS to a desirable level of activity is clearly shown and proves the results experienced by the client.

Progress is being made in discovering the ability of TFT to address and sometimes resolve physical problems in the body. Such results are again clearly shown by the use of Heart Rate Variability (HRV) testing.


The toxins recognised by Thought Field Therapy® are not the same as those in conventional medicine which are true poisons like carbon monoxide, cyanide, arsenic, etc… The toxins are seemingly innocuous substances such as sugar, chocolate, wheat and corn, which can disrupt the body’s healing systems and prevent perturbations in Thought Fields from being deactivated permanently.

Toxins can also include inhaled substances, like cigarette smoke and perfumes, and substances, which may be in contact with the skin, such as washing powder, household products, personal hygiene products and cosmetics. It may be necessary to avoid contact with these substances for a few weeks (or sometimes permanently) to allow the energy system to restore itself.

Thought Field Therapy® (TFT) was discovered in 1980 by Dr Roger Callahan PhD, one of America’s most experienced and distinguished Clinical Psychologists. Dr Callahan was dissatisfied with conventional techniques which he found to be time consuming and largely ineffective. He became interested in an alternative therapy called Applied Kinesiology (AK), which addresses the body’s energy meridian system and realised that some of its techniques could have an application in the treatment of negative emotions. The first patient he treated with what we now know as TFT was a middle-aged lady called Mary, who had a severe phobia of water.

Dr Callahan had treated Mary for 18 months without much success using conventional methods. One day, with little or nothing left to offer, he experimented with his newly found technique. He knew Mary had described her fear as being felt in the stomach, and he also knew that the stomach meridian began under the eyes. So he simply tried finger tapping under Mary’s eyes. Her phobia promptly vanished and has stayed away to this day.
Dr Callahan soon discovered that this basic treatment was ineffective with most other patients, but with years of research and experimentation, the success rate steadily increased to deliver the end-product that we now know as Callahan Techniques® Thought Field Therapy® (TFT for short).
