As professional hypnotherapists, we always want to know more about the studies and research involving hypnosis, as well as more about how the medical industry is progressing in its use and applications of hypnosis.
HypnosisAndSuggestion.org is an excellent resource for researching more about the medical side of hypnosis, consisting of grouping citations and studies together by topic. A few hours of browsing this site will familiarize you with many of the studies mentioned in press articles. If you ever have doctors asking you for resources about medical hypnosis, giving them this site is a great start.
Some of the actual texts of the studies and the journals linked require membership or subscription, and all of the organizations on the links pages require state-licensing in the medical or mental health field in order to join (so, doctors, nurses, social workers, etc. with current credentials).
This is a great place to read up on studies and the structure of studies, and a smart place for the professional hypnotherapist to spend some time learning.
