fa Reliability and validity of the Chinese version of the Chronic Oral Mucosal Diseases Questionnaire ترمیمی Cosmetic and Restorative Dentistry پژوهشي Research <p> <strong>Introduction:</strong></p><p>   The aim of this study was to evaluate the reliability and validity of the Chinese version of the Chronic Oral Mucosal Diseases Questionnaire (COMDQ). </p><p> <strong>Methods:</strong></p><p> <strong> </strong> 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). </p><p> <strong>Results:</strong>  </p><p> 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. </p><p> <strong>Conclusion</strong>:  </p><p> 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. </p><hr><p></p><p> <strong>Source: </strong>Journal of Oral Pathology & Medicine</p><p> <a href="http://onlinelibrary.wiley.com/doi/10.1111/j.1600-0714.2012.01157.x/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> chronic oral mucosal diseases;quality of life;questionnaire;reliability and validity 0 0 http://idai.ir/browse.php?a_code=A-10-32-2236&slc_lang=fa&sid=1 Min Li 100319475328460010554 100319475328460010554 No Chongqing Research Center for Oral Diseases and Biomedical Science, Chongqing, China/Department of Periodontology and Oral Medicine, The Affiliated Hospital of Stomatology, Chongqing Medical University, Chongqing, China Song-Lin He songlinhecqmu@163.com 100319475328460010555 100319475328460010555 Yes Chongqing Research Center for Oral Diseases and Biomedical Science, Chongqing, China/Department of Preventive and Pediatric Dentistry, The Affiliated Hospital of Stomatology, Chongqing Medical University, Chongqing, China
