Sleep deficiency, psychological distress, daytime dysfunction and abdominal pain are common in adults with irritable bowel syndrome (IBS). Prior research on individuals with chronic pain has identified the indirect effect of sleep on pain through psychological distress or daytime dysfunction; however, it is less clear in IBS. The purpose of this study was to examine potential indirect effects of sleep on abdominal pain symptoms simultaneously through psychological distress and daytime dysfunction in adults with IBS.
