Welcome to The International Hypnosis Research Institute Web site. Our intention is to support and promote the further worldwide integration of comprehensive evidence-based research and clinical hypnotherapy with mainstream mental health, medicine, and coaching. We do so by disseminating, supporting, and conducting research, providing professional level education, advocating increased level of practitioner competency, and supporting the viability and success of clinical practitioners. Although currently over 80% of our membership is comprised of mental health practitioners, we fully recognize the role, support, involvement, and needs of those in the medical and coaching fields.

Full Title: Hypnotizability and opinions about hypnosis in a clinical trial for the hypnotic control of pain and anxiety during pregnancy termination

This descriptive study evaluates the hypnoanalgesic experience's effect on participants' hypnotizability and opinions about hypnosis and identifies factors associated with hypnotizability. Hypnotizability was assessed using the Stanford Hypnotic Susceptibility Scale: Form A in 290 women 1 month after their participation in a randomized clinical trial evaluating hypnotic intervention for pain/anxiety versus standard care during pregnancy termination. Opinions were collected before and after the intervention. The regression model describing hypnotizability (F = 13.55; p < .0001; R(2) = 0.20) retained 5 variables but not the intervention group. The variable explaining most of total variance (62.9%) was the level of perceived automaticity/involuntariness. Opinions about hypnosis were modified by the hypnotic experience compared to standard care but were not associated with hypnotizability. Exposure to hypnoanalgesia did not influence hypnotizability but modifies significantly the opinions about hypnosis. Consistent with previous findings, perceived automaticity appears to best predict hypnotizability.
