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.
