RESEARCH INTRODUCTION

A 3-month home-treatment version of the standardized North Carolina hypnosis protocol previously shown to improve all central IBS symptoms was completed by 19 IBS patients. Outcomes were compared to those of 57 matched IBS patients (1-to-3 matching) from a separate study receiving only standard medical care. Ten of the hypnosis subjects (53%) responded to treatment by 3-month follow-up (response defined as more than 50% reduction in overall IBS severity) vs. 15 (26%) of controls. Hypnosis subjects improved more in quality of life scores compared to controls. Having clinically significant anxiety scores was found to predict poor hypnosis treatment response. Hypnosis responders remained improved at 6-month follow-up. Response rate was lower in this study than previously observed in therapist-delivered treatment with the North Carolina protocol, but this was likely due to the fact that stricter criteria for significant improvement were used than in the other studies. The results of this study suggest that hypnosis home treatment with the North Carolina protocol may double the proportion of IBS patients who improve significantly in their bowel symptoms over a 6 month period.

 

ABSTRACT

Hypnosis treatment often improves irritable bowel syndrome (IBS), but the costs and reliance on specialized therapists limit its availability. A 3-month home-treatment version of a scripted hypnosis protocol previously shown to improve all central IBS symptoms was completed by 19 IBS patients. Outcomes were compared to those of 57 matched IBS patients from a separate study receiving only standard medical care. Ten of the hypnosis subjects (53%) responded to treatment by 3-month follow-up (response defined as more than 50% reduction in IBS severity) vs. 15 (26%) of controls. Hypnosis subjects improved more in quality of life scores compared to controls. Anxiety predicted poor treatment response. Hypnosis responders remained improved at 6-month follow-up. Although response rate was lower than previously observed in therapist-delivered treatment, hypnosis home treatment may double the proportion of IBS patients improving significantly across 6 months.
