How effective are psychological interventions for the treatment of irritable bowel syndrome (IBS)?
The results of this meta-analysis should be interpreted with caution due to the low methodological quality of the included studies, variability in outcome definitions and small sample sizes which resulted in considerable heterogeneity.
IBS is a chronic functional gastrointestinal disorder, with an estimated prevalence in Europe of up to 24% in women and 19% in men.¹ No consensus exists on the optimal treatment for IBS. Psychological treatments are increasingly advocated but their effectiveness is unclear. 1. Drossman DA et al. Gastroenterology 1997;112:2120-2137
