July 12, 2026 updated by: Pei-Lin Yang, National Defense Medical Center, Taiwan

A Pilot Randomized Controlled Trial of a Taiwanese Version of a Comprehensive Self-Management Program for Adults With Irritable Bowel Syndrome

This pilot randomized controlled trial will evaluate the feasibility, acceptability, and preliminary effects of a Taiwanese version of a comprehensive self-management program for adults with irritable bowel syndrome. Participants will be randomized to the self-management program or usual care. Outcomes will be assessed at baseline, immediately after the intervention, and three months after the intervention.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will enroll adults with irritable bowel syndrome and randomize participants in a 2:1 ratio to an 8-session comprehensive self-management program or usual care. The program includes irritable bowel syndrome education, symptom monitoring, relaxation practice, cognitive strategies, dietary self-management, sleep-related content, problem solving, and daily-life symptom management. The pilot trial will assess recruitment, retention, intervention adherence, acceptability, satisfaction, and preliminary changes in symptom-related outcomes.
