The increasing interest in research in IBS and other functional gastrointestinal disorders (FGIDs) and the growing sophistication of communication technology make cross-cultural, multinational research a feasible endeavor. Collaborative multinational, cross-cultural studies in FGIDs, using appropriate research methodology, can make a significant contribution to the understanding of FGIDs and to patient care. The working team on Cross-cultural, Multinational Research in the Functional Gastrointestinal Disorders has completed its work and has produced several published articles relating to methodological issues in multinational research and fostering of multinational research as well as a Final Report, available here.
