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:
