Can We Consider EFT to be an Evidence-Based Treatment Method from a Scientific Point of View?

Updated: May 9, 2020

Before I became a psychologist, I trained as a microbiologist and later worked in microbiology, medical biochemistry and commercial chemistry laboratories.

So, my initial training was as a scientist and I am still reassured by sound scientific evidence that a particular psychotherapy method works.

We label such methods as being ‘evidence-based.’

So, is EFT Evidence-Based?

Well, I’ll explore this via the criteria of the American Psychological Association (APA) - the controlling body for psychologists in the USA - a very conservative body with very stringent criteria for the acceptance of a method as being “efficacious” (i.e. evidence-based).

The APA stipulates several criteria that have to be satisfied before we can call a treatment an “efficacious.”

They stipulate that a treatment can only be called “efficacious” if:

  • at least two different controlled trials

  • are conducted by independant research teams

  • and the statistics show with a 95% probability that the results are not due to chance

  • and the results demonstrate that the treatment is better than a wait list, placebo, or established efficacious treatment.

Now, it is notoriously difficult to show that a psychotherapy method is efficacious.

Only about 20% of new psychotherapy methods eventually become recognised as being efficacious and it typically takes around 17 years for a method to achieve this status.

With EFT, it has been particularly difficult.

EFT combines elements of Traditional Chinese Medicine (TCM) with western psychological methods and so the method looks strange.

Furthermore, clinicians using EFT typically report results that appear to be too good to be true.

These have led many clinicians, researchers and funders to be rather sceptical.

And, if the funders are sceptical, financial support for research is very limited. Despite all of this, to date, EFT has been able to meet the stringent APA standards and has been accepted as an “efficacious” treatment for phobias, anxiety, depression and PTSD.

This conclusion was reached as early as 2012 and was based on 51 peer-reviewed papers and which included 18 randomised controlled trials (Feinstein, 2012).

Randomised controlled trials are considered to be the ‘gold standard’ in psychological research and such trials aim to compare a new treatment to an existing treatment (or to no treatment or to a pseudo treatment), in a completely unbiased way. It does this by assigning subjects to two (or more) existing treatments, in a random way and then comparing results.

At the time of writing this article (April 2020), there are more than a 100 studies demonstrating the efficacy of EFT for variety of issues (Bach, 2019) and there are now at least 24 randomised controlled trials published in peer-reviewed journals all demonstrating that EFT is effective in treating a wide range of issues (Feinstein, 2020).

Some of these findings are very striking. A meta-analysis (a high-level statistical analysis) of 20 studies on EFT for depression by Jerrod et al (2016), for example, concluded that EFT was more effective than:

  • antidepressant drug trials

  • or psychotherapy.

In another study by Karatzias et al (2011), EFT was compared with one of the gold standard treatments for the treatment of PTSD (EMDR) and EFT and EMDR were found to be equally efficacious.

So, we can confidently say that EFT is an evidence-based treatment for phobias, anxiety, depression and PTSD.

But, this is by no means a complete list of issues for which EFT is claimed to be useful.

Clinical reports and preliminary research have reported EFT to also be effective in:

  • Lowering stress levels

  • Lowering levels of irrational anger

  • Lowering levels of jealousy

  • Lowering levels of guilt

  • Lowering levels of shame

  • Resolving unremitting grief

  • Reducing performance

  • Reducing test anxiety

  • Increasing performance

  • Reducing chronic pain including fibromyalgia

  • Reducing cravings

  • Reducing cortisol levels

  • Reducing blood pressure

  • Reducing resting heart rate

  • Raised immunoglobulin levels

  • Improved heart rate variability

  • Raising levels of happiness and sense of well-being

Further research is required on the use of EFT with these issues in order to meet all of the APA requirements. So, a conservative view would be to say that EFT for these issues is at an experimental stage (Feinstein, 2020), pending further research.

That having been said, EFT is being used to treat all of these issues by thousands of professionals worldwide and the clinical reports continue to be very positive.

In addition to this, research continues at many prestigious institutions including:

  • Harvard Medical School

  • The University of California at Berkeley

  • City University of New York

  • Walter Reed Military Medical Center

  • Texas A&M University

  • JFK University

  • Staffordshire University (United Kingdom)

  • Lund University (Sweden)

  • Ankara University (Turkey)

  • Santo Tomas University (Philippines)

  • Lister Hospital (England)

  • Cesar Vallejo University (Peru)

  • Bond University (Australia)

  • and Griffith University (Australia).

I am certain that, in time, EFT will be widely considered to be a highly-valued, effective and efficient, evidence-based treatment for a much wider range of disorders.
