Is there any evidence for it? How do you get qualified? Is it used in more traditional therapy?
I'll use this Quickstart Guide to EFT (PDF) as a basis to discuss the Emotional Freedom Technique.
EFT is based on the assumption that
It works by tapping on specific meridian points with your fingertips which "balances energy meridians". It is claimed that this heals about any psychological problem you can think of.
There is no scientific basis for the existence of meridians in our bodies. The basic principles of EFT are not based on science, but on a vague concept of energy, that has no relation to any established scientific principles.
There have been a number of small studies on EFT. The largest one of those with 119 participants divided into 4 groups did not find EFT significantly more effective than placebo. One small study with 5 participants in each group, performed by the originator of the technique found a significant effect of EFT. Due to the small sample size and the fact that the journal it was published in is dedicated to alternative medicine, I would not consider these results as proof of effectiveness.
I did not find any convincing studies that would show the effectiveness of this technique. Considering the implausible mechanism it is based on, I would safely argue that EFT is extremely unlikely to work better than placebo and should not be considered a credible treatment for psychological issues.
