What this trial studies

WISH 2.0 randomizes adults who meet Rome IV criteria for IBS to an optimized positive psychology (PP) intervention or an educational control to examine feasibility, acceptability, and preliminary effects. The PP program is designed for scalable, remote delivery using structured exercises to boost positive psychological well-being, while the control provides education about IBS. Outcomes include patient-reported well-being, IBS symptoms, health-related quality of life, and candidate gut–brain mechanism measures, along with feasibility and acceptability metrics. Key exclusions include inflammatory bowel disease, severe psychiatric illness, cognitive impairment, and certain cardiac conditions or medications.

Who should consider this trial

Good fit: Adults with IBS who meet Rome IV diagnostic criteria, speak English, have phone access, and do not have IBD, severe psychiatric illness, cognitive impairment, or disqualifying cardiac issues are ideal candidates.

Not a fit: Patients whose symptoms are better explained by inflammatory bowel disease or other structural GI disease, those with severe unmanaged psychiatric illness or cognitive impairment, or those unable to participate remotely or who plan to start other psychotherapy are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the program could improve well-being, reduce IBS symptoms, and provide a scalable, low-burden behavioral option for people with IBS.

How similar studies have performed: Positive psychology interventions have produced benefits in other chronic medical conditions, but aside from preliminary proof-of-concept work by the investigators, PP has not been tested in IBS.
