January 9, 2026 updated by: Magnus Simrén, Sahlgrenska University Hospital
Adult IBS patients with symptoms refractory to standard medical treatment will receive online nurse-administered, gut-directed hypnotherapy in groups. The primary outcome measure was change in gastro-intestinal symptom severity. Secondary outcomes are GI-specific anxiety, general anxiety and depression, quality of life, and extracolonic symptom severity. Usability of the digital platform as well as patient treatment satisfaction will also be assessed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in gastrointestinal symptom severity measured by the IBS Severity Scoring System questionnaire (IBS-SSS)
Time Frame: Baseline (week 0), during treatment (week 6), at treatment completion (week 12), follow-up (6 months, 1 and 2 years after treatment initiation)
The score is calculated from 5 items: pain severity, pain frequency, abdominal bloating severity, bowel habit dissatisfaction and daily life interference. The score ranges from 0-500. A higher the score signifies more severe symptoms. A symptom score reduction of 50 points or more after treatment compared to the baseline score is considered a response to treatment.
Baseline (week 0), during treatment (week 6), at treatment completion (week 12), follow-up (6 months, 1 and 2 years after treatment initiation)
