Pilot Study of a Self-Administered Hypnosis Intervention for Functional Dyspepsia.

ABSTRACT

BACKGROUND: Functional dyspepsia (FD) is a chronic disorder of the upper gastrointestinal tract that currently lacks substantially effective therapy options. AIMS: To evaluate the feasibility and potential impact on FD symptoms and well-being of a fully automated gut-directed hypnosis intervention delivered via audio recordings. METHODS: FD patients were enrolled at a single medical center and given access to a password-protected website where they completed 7 bi-weekly audio-recorded hypnosis sessions over a 3-month period. Study questionnaires including the Patient assessment of upper gastrointestinal symptom severity index, Short-Form Nepean Dyspepsia Index, the Visceral Sensitivity Index, and the Brief Symptom Inventory (BSI-18) were completed online pre-treatment, mid-treatment, post-treatment and at 3-month follow-up. RESULTS: Of 23 enrolled patients (18 females; mean age = 38 years), 96% completed the entire treatment program and 3-month follow-up. Intention-to-treat analyses showed significant improvement at both end of treatment and 3-month follow-up in dyspepsia severity and quality of life, as well as in gut-specific anxiety and psychological distress. 68% of treatment completers reported that their FD symptoms were improved. Improvement in FD severity was significantly positively correlated with baseline PAGI-SYM total scores and BSI Global Severity Index scores. CONCLUSIONS: The fully automated hypnosis audio treatment program, which requires no therapist or clinician involvement, demonstrated excellent feasibility and resulted in significant improvement in FD symptoms, quality of life and emotional well-being. The results indicate that the intervention has high potential as adjunctive therapy for FD and warrants further investigation in a randomized controlled trial.
