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.
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.

The group intervention is carried out once a week for 10 weeks for a total of 60 hours with elements of mindfulness-based stress reduction (MBSR) and mind / body medicine. In this project, this program will be adapted to the specific needs of irritable bowel syndrome patients.
Participants in this group receive a one-time education unit within the scope of 1,5 hours on the influence of lifestyle factors on the disease, also self-help materials for independent training offered. Following the follow-up measure also this group is given the opportunity to participate in the multimodal stress reduction- and lifestyle modification program.

Disease related Quality of Life by IBS-QOL
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.

General Quality of Life by EQ-5D-SL
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
