Objective 　To evaluate the reliability and validity of IBS-QOL scale in irritable bowel syndrome (IBS) patients.
Methods 　IBS-QOL scale was applied to survey the quality of life of 123 IBS patients. The split-half and internal consistency method were used to evaluate the reliability, and with the construct method to evaluate the validity.
Results 　The split-half reliability was 0.86. Cronbach’s α-coefficient of all domains was between 0.71 and 0.89 except body image and food avoidance; In the correlation analysis, the correlations between items and its subscale structure were above 0.60 (except interference with activity), but there were no correlations between items and other subscale structure. Eight components from factorial analysis were in accordance with theoretical structure.The cumulative contribution rate was 72.7%.
Conclusions 　The reliability and validity of IBS-QOL scale are acceptable. It might be useful for us to assess the QOL of IBS patients in China.
