Abstract：Objective:To translate the Inflammatory Bowel Disease Control Questionnaire(IBD-CQ)into Chinese,and to test the reliability and validity of the IBD-Control-8 score.Methods:The IBD-CQ was translated into Chinese according to the Brislin translation model.A total of 334 patients with inflammatory bowel disease(IBD)were investigated to verify the reliability and validity of the questionnaire.Results:The Chinese version of the IBD-CQ consists of 13 items.A visual analogue scale(IBD-VAS),with scores based on two dimensions of therapeutic domains and health-related quality of life,and a total of eight items constituted the IBD-Control-8 score.The item level content validity index of the scale was 0.86-1.00.The overall consistency content validity index was 0.97.Exploratory factor analysis extracted two common factors with a cumulative variance contribution of 66.936%.Calibration validity analysis showed a significant positive correlation between the IBD-Control-8 scores and the IBDQ scores(r=0.71,P<0.001).The Cronbach's α coefficient for the IBD-Control-8 scores was 0.894.Cronbach's alpha coefficients for the dimensions ranged from 0.836 to 0.950.The folding coefficient was 0.857.And the retest reliability coefficient was 0.849.Conclusion:The Chinese version of the IBD-CQ has good reliability and validity.It could be used as an assessment tool for evaluating subjective perceptions of disease control and treatment outcomes for patients with inflammatory bowel disease.
