OBJECTIVE: Irritable bowel syndrome (IBS) is a psychosomatic gastrointestinal disorder involving the dysfunctional activation of specific brain regions crucial for interoception and disgust processing. Yet, no study has ever investigated the link between this socio-affective/visceral experience and IBS.

METHOD: The present study investigated whether disgust sensitivity and disgust propensity, which can be socially relevant, relate with IBS symptoms in a nonclinical population.105 healthy participants were asked to complete the Disgust Propensity and Sensitivity Scale-Revised (DPSS-R), the Irritable Bowel Syndrome-Quality of Life Measure (IBS-QOL), and the Chronic Urticaria Quality of Life Measure (CU-Q2OL), as control condition.

RESULTS: Results showed higher disgust sensitivity scores in individuals with high IBS-QOL score, compared to individuals with low IBS-QOL score. The correlation analysis corroborates this result by showing a positive relationship between disgust sensitivity and respective IBS-QOL scores.

CONCLUSIONS: This research provides new insights into understanding the etiopathogenesis of IBS, suggesting the relevance of a socially relevant personality trait such as disgust sensitivity as a potential trigger and / or predisposition factor for this chronic inflammatory disease.
