Brief Summary

In the planned efficacy study, a prospective randomized controlled trial will be conducted to investigate the extent to which a multimodal stress reduction and lifestyle modification program can be reflected in patients with irritable bowel syndrome (IBS) within the framework of a clinical study. For this purpose, 118 patients with IBS will be enrolled in a clinical study. The intervention group will participate in a partial outpatient multimodal stress reduction and lifestyle modification program over 10 weeks, while the waitlist control group will only receive an educational session and written information on treatment and self-help options. The primary research question encompasses the examination of the program's impact on the severity of symptoms associated with irritable bowel syndrome (measured with the IBS-Symptom Severity Scale \[IBS-SSS\]) and additionally its influence on quality of life, stress, and mental well-being. Another aspect of the study is the utilization of medical services (e.g., comparing the number of doctor visits; intake of prescribed and over-the-counter medications). Additionally, a comparison of days of work disability will be conducted.

Detailed Description

The intervention is a 10-week multimodal stress reduction and lifestyle modification program consisting of 10 sessions, each lasting 6 hours. In groups of around 10 individuals, patients are comprehensively trained on the interplay between lifestyle and health, stress management, moderate physical activity (including yoga and Tai Chi), a Mediterranean diet, and self-help strategies. Successfully tested in two pilot studies, the program has evolved over 15 years and gained clinical experience in chronic inflammatory bowel diseases. It is now being applied to patients with irritable bowel syndrome (IBS).

Built on concepts like the Mind-Body Program and mindfulness-based stress reduction, the intervention incorporates elements from salutogenic and transtheoretical models and psychotherapeutic approaches.

Few integrative medicine approaches for IBS have undergone rigorous evaluation. IBS patients often experience reduced quality of life due to stress and psychosocial symptoms. The program, proven effective in inflammatory bowel diseases, covers stress reduction, dietary improvement, physical activity promotion, self-care applications, coping strategy training, and naturopathic treatments. Medically supervised, the group setting aims to enhance the intervention's impact through mutual support. Practical skills are demonstrated, and the goal is to empower patients for active, responsible, long-term management.

Participants in the waitlist control group receive a 1,5-hour educational session on lifestyle factors' influence and self-help materials. After week 36 measurements, they are offered participation in the multimodal program.

Questionnaires, a diary, and interviews will measure the outcomes of the study. Sociodemographics will be collected.

Primary Outcome Measures
NameTimeMethod
overall change in health statusweek 36

Rating scale from 1 (= much worse) to 5 (= much better)

Severity of IBS symptoms by IBS-SSSweek 36

Irritable bowel syndrome severity scoring system (IBS-SSS); 5-item questionnaire; scale from 0% (= not at all) to 100% (= very severe); cut-off of IBS-SSS scores to evaluate the severity of IBS: \< 175 for mild IBS, 175-300 for moderate IBS, and \> 300 for severe IBS

Secondary Outcome Measures
NameTimeMethod
Qualitative Interviewsweek 12

Qualitative interviews for gaining further insights into patients experiences

Disease related Quality of Life by IBS-QOLweek 36

The IBS-QOL is a self-report quality-of-life measure specific to Irritable Bowel Syndrome (IBS) that can be used to assess the impact of IBS and its treatment. 34 items with a 5-point response scale from 1 (=not at all) to 5 (= Extremely/a great deal); 34 items are summed and averaged for a total score and then transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS specific quality of life.

Core Self-Evaluation by CSESweek 36

Core Self-Evaluation (CSES), 12 items on five-point Likert scale, 1 indicates disagreement and 5 indicates full agreement. High scores on the CSES represents a positive, confident, and self-efficacious person

Anxiety and depression by HADSweek 36

Hospital Anxiety and Depression Scale (HADS), 14 items (7 each for depressive symptoms or symptoms of anxiety). The two summated scores of the summated scales HADS-A and HADS-D range between 0 and 21. high scores indicate depressivness and anxiety.

General Quality of Life by EQ-5D-SLweek 36

The EQ-5D assesses health status in terms of five dimensions of health (mobility, self-care, usual activities, pain and discomfort, and anxiety and depression) and is considered a 'generic' questionnaire because these dimensions are not specific to any one patient group or health condition. 5-point response-scale from 1 (=not /no problems) to 5 (=unable to \[mobility, self-care, usual activities\]/extreme \[pain/depression\]/extremely \[anxiety/depression\]); result: 5-digit health status profile that represents that person's level of reported problems on the five EQ-5D health dimensions

Adverse eventsweek 36

Utilization of medical servicesweek 36

Number of visits

Stress: Perceived Stress (PSS-10)week 36

Perceived Stress Scale (PSS), Rating on a five-step scale from 1 (= never) to 5 (=very often), high stress is assumed from a total score of 20 points

Stress: Coping Strategies (CISS)week 36

Short version of the Coping Inventory for Stressful Situations (24 items); Rating on a five-step scale from 1 (= not at all) to 5 (= very much); sum score for each coping strategy; higher scores indicate a greater use of that particular coping strategy
