I get asked a great deal about the kinds of studies and research that are useful to explore or quote when hypnotherapy is discussed. I often refer to a handout that I was given by Donald Robertson a number of years ago.
It contained a number of studies used to assess whether hypnosis can be considered specific, effective or possible as an empirically-supported treatment and although there are numerous other studies, these were the ones highlighted and included in “What we can do with hypnosis: a brief note” by David Wark in the American Journal of Clinical Hypnosis back in 2008. I thought you might quite like to see it and hopefully benefit from it as much as I have done throughout the years:

Likewise, if you’d like to learn more about self-hypnosis, understand the evidence based principles of it from a scientific perspective and learn how to apply it to many areas of your life while having fun and in a safe environment and have the opportunity to test everything you learn, then come and join me for my one day seminar which does all that and more, have a read here: The Science of Self-Hypnosis Seminar. Alternatively, go grab a copy of my Science of self-hypnosis book.
Really useful stuff -thanks v.much
Thanks Colin, good hearing from you, A.
Would love to see this document as a wiki with up-to-date information 🙂
Thanks for the resource!
Thanks Jeremy. There is some criteria to be met in order to officially be permitted to term something “empirically supported treatment” and though the body of evidence we have in our field is growing, much of the research does not often qualify as an EST.
Best wishes, A.
That is a useful.
Also I would highlight the following meta analysis:

Thank you Thorbjorn, best wishes to you, Adam.
