To be included, studies were required to utilize a between-subjects or mixed model design in which a hypnosis intervention was compared with a control condition in alleviating any form of clinical pain. Of 523 records screened, 42 studies incorporating 45 trials of hypnosis met the inclusion criteria. Our most conservative estimates of the impact of hypnosis on pain yielded mean weighted effect sizes of 0.60 (<i>p</i> ≤ .001) for 40 post trials and 0.61 (p ≤ .001) for 9 follow-up trials. These effect sizes fall in the medium range according to Cohen's guideline and suggest the average participant receiving hypnosis reduced pain more than about 73% of control participants. Hypnosis was moderated by the overall methodological quality of trials-the mean weighted effect size of the 19 post trials without high risk ratings on any of the Cochrane Risk of Bias dimensions was 0.77 (p ≤ .001). Hypnosis was also moderated by hypnotic suggestibility, with 6 post trials producing a mean weighted effect size of <i>r</i> = 0.53 (p ≤ .001).

While there are overlapping brain networks involved, the nature of these effects seems different. Both phenomena involve frontal modulation of pain-related areas. The role of the dorsolateral prefrontal cortex appears to depend, in hypnosis, on the type of suggestion given and, in meditation, on the level of practice.

From conception, the HIP has been utilized in clinical settings to assess appropriateness for the use of hypnosis in treatment planning and research protocols to stratify research participants.
