A Review of Studies on Patient-reported Outcomes and Disease-specific Health-related Quality of Life Instruments for Irritable Bowel Syndrome

Abstract

Scale assessment for irritable bowel syndrome (IBS) has been widely implemented in clinical practice, how to choose an appropriate assessment tool is very important. In view of this, we used literature research methodology to search patient-reported outcomes and disease-specific health-related quality of life instruments for IBS, summarized their main contents and psychometric properties, then put forward recommendations on the selection of the instruments. A total of 37 commonly used instruments for IBS were retrieved, which have proven to have good reliability, validity and responsiveness, and can be better applied in clinical practice. We suggest medical professionals and researchers choose an assessment instrument for IBS according to the purpose and content of their research.
