Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Psychological therapies are effective in reducing irritable bowel syndrome (IBS) symptom severity and increasing quality of life and are recommended for the management of IBS by guidelines. Evidence appears strongest for the efficacy of hypnotherapy as psychological treatment. However, therapist-led interventions are time consuming and relatively costly. Approaches based on e-health are cost saving and appear more attractive to patients as no visits to a therapist are necessary. Therefore, the investigators plan to conduct a multicentre randomised controlled trial to examine whether the effectiveness of online hypnotherapy is non-inferior compared to individual face-to-face hypnotherapy delivered by a therapist, according to current FDA guidelines. Online psychoeducation will be used as control condition. In addition, the investigators hypothesize that treatment with online hypnotherapy is a more cost-effective therapy than face-to-face hypnotherapy in IBS patients.
