%X Aim. To investigate the degree of mental strain and chronic stress in a German community sample of students with IBS-like symptoms. Methods and Materials. Following an internet-based survey about stress, this study recruited 176 German university students ( years; 48.3% males) with IBS-like symptoms according to Rome III and 181 students without IBS ( years; 50.3% males) and compared them regarding current mental strain (SCL-90-R) and the extend of chronic stress. Beyond this, IBS subtypes, IBS severity, and health care utilization were assessed. Results. Students fulfilling IBS criteria showed significantly elevated values of mental strain and chronic stress. Nearly 40% of the IBS group (versus 20% of the controls) reached a clinically relevant value on the SCL-90-R global severity scale. IBS subtypes did not differ in terms of mental distress or chronic stress. Somatization, anxiety, and the chronic stressors ¡°work overload,¡± ¡°social tension,¡± and ¡°dissatisfaction with job¡± were most closely connected to IBS symptom severity. Regarding health care utilization, our results show that consulting a physician frequently was not associated significantly with elevated mental strain or chronic stress but with IBS symptom severity. Conclusion. Our data contribute additional evidence to the distinct association between psychological stress and IBS in community samples. 1. Introduction Irritable bowel syndrome (IBS) is a frequent functional gastrointestinal disorder which is characterized by recurrent abdominal pain or discomfort and altered bowel function without an explanatory organic etiology. Despite constipation and/or diarrhea, additional gastrointestinal symptoms like bloating and sensation of incomplete evacuation are experienced quite often. Epidemiologic data on this disorder vary a lot depending on the examined sample and the diagnostic criteria used. The prevalence of IBS in the general population is estimated to be in the range between 10% and 20% [1¨C5]. Our previous study has shown that the prevalence of Rome III IBS symptoms among German university students is 18.1% with a significant difference between males (15.2%) and females (21.0%) [6]. IBS, especially in a moderate or severe manifestation, has a considerable impact on health-related quality of life and daily functioning [7¨C9]. The pathogenic mechanisms of IBS are not fully known. There is strong evidence of altered physiologic features of persons suffering from IBS such as abnormal gastrointestinal motility [10¨C12] and heightened visceral sensitivity [13¨C15]. Gastrointestinal infections have
