Abstract：Objective:the Quality of Life in Patients with Anal Fistula Questionnaire(QoLAF-Q)was used to test its reliability and validity in patients with anal fistula.To provide a specific tool for clinical assessment of quality of life in patients with cryptoglandular anal fistula.Methods:After obtaining authorization from the original authors,the questionnaire was translated into Chinese following Brislin's translation principles,forming the Chinese version of the QoLAF-Q.A convenience sampling method was used to survey 390 patients with anal fistula,evaluating the reliability and validity of the questionnaire.Results:A total of nine experts were invited to assess the content validity of the Chinese version of the QoLAF-Q,with an expert authority coefficient(Cr)of 0.88.The item-level content validity index(I-CVI)ranged from 0.889 to 1.000,and the average scale level content validity index(S-C VI/Ave)was 0.936.Exploratory factor analysis extracted two common factors,accounting for 70.523％of the cumulative variance,with all item factor loadings greater than 0.400.Confirmatory factor analysis showed good model fit.The overall Cronbach's alpha coefficient of the questionnaire was 0.908,the test-retest reliability was 0.873,and the split-half reliability was 0.946.Conclusions:The Chinese version of QoLAF-Q has good reliability and validity,making it an effective and specific tool for assessing the quality of life in patients with cryptoglandular anal fistula.
