Abstract：To study the reliability and validity of simplified Chinese version of inflammatory bowel disease questionnaire(IBDQ),and provide assessment tool for reasonable measurement of quality of life of pa-tients with inflammatory bowel disease.Methods:By convenience sampling method,a total of 90 cases of inflam-matory bowel disease patients who were diagnosed in outpatient clinic or hospitalization department in affiliated hospital of Nantong university and second affiliated hospital of Nantong university from October 2012 to 2014 March were selected.All the patients used IBDQ to investigate for the first time,with disease activity index was taken as the disease staging criteria.The patients with Crohn’s disease were evaluated by using simplified Crohn’s disease activity index(CDAI),and the ulcerative colitis patients received a simplified colitis activity in-dex colitis activity index(CAI)to assess the condition.CDAI or Cai<4 points for disease remission,and the IB-DQ was used again for survey of quality of life of patients in remission period after two weeks to four weeks, then to measure the reliability and validity of the scale after gaining data.Results:In simplified Chinese version of IBDQ,Cronbach’s alpha was 0.986,Cronbach’s alpha for four dimensions was respectively intestinal symp-toms of 0.968,systemic symptom of 0.937,emotional function of 0.967,social function of 0.954.Scale binary coefficient was 0.987,binary coefficients of all dimensions were intestinal symptoms 0.977,systemic symptom 0.910,emotional function 0.973 and social function 0.927.The ICC coefficients included intestinal symptoms 0.982, systemic symptom 0.967,emotional function 0.991 and social function 0.978 respectively.IBDQ content validi-ty was better that showed by the Person correlation analysis(P <0.05).IBDQ can distinguish the activity Period and remission period and the discrimination was better.Conclusion:The reliability and validity of simplified Chi-nese version of IBDQ are good,and can sensitively distinguish disease activity and remission period,and is appli-cable to the survey of inflammatory bowel disease patients’quality of life.
