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. This site is not intended as a source of medical or psychological advice. Tim Brunson, PhD

PTSD symptoms, substance use, and vipassana meditation among incarcerated individuals.

The present study evaluated whether Posttraumatic Stress Disorder (PTSD) symptom severity was associated with participation and treatment outcomes comparing a Vipassana meditation course to treatment as usual in an incarcerated sample. This study utilizes secondary data. The original study demonstrated that Vipassana meditation is associated with reductions in substance use. The present study found that PTSD symptom severity did not differ significantly between those who did and did not volunteer to take the course. Participation in the Vipassana course was associated with significantly greater reductions in substance use than treatment as usual, regardless of PTSD symptom severity levels. These results suggest that Vipassana meditation is worthy of further study for those with comorbid PTSD and substance use problems.
