Abstract
INTRODUCTION: The aim of this study was to evaluate the reliability and validity of the Chinese version of the Chronic Oral Mucosal Diseases Questionnaire (COMDQ). METHODS: A consecutive sample of 200 patients with chronic oral mucosal diseases was enrolled to complete the questionnaire after its translation and cross-cultural adaptation. The reliability of the Chinese version of COMDQ was determined through internal consistency and test-retest methods. The construct validity of COMDQ was analysed by exploratory factor analysis (EFA). RESULTS: Cronbach's alpha value for the total COMDQ score was 0.894, and the test-retest intraclass correlation coefficient value for the total COMDQ score was 0.83. The EFA extracted four factors, which accounted for 67.89% of the variance. All items showed adequate factor loadings, ranging from 0.487 to 0.947. CONCLUSION: The results suggest that the Chinese version of the COMDQ has satisfactory psychometric properties and is applicable to patients with chronic oral mucosal diseases in China.
