Chronic oral mucosal diseases have been a common problem, which affected individuals' health and social functions seriously. Although there has been a rigorous Chinese version of the Chronic Mucosal Diseases Questionnaire (COMDQ-26) to measure the quality of life of patients with chronic oral mucosal diseases, 26 items were so redundant to be a burden for patients. It was necessary to make a brief, practical, and easy-to-use tool in China. This study aimed to test the validity and reliability of the Chinese version of the short-form Chronic Mucosal Diseases Questionnaire (COMDQ-15).
A total of 165 respondents from a tertiary stomatological hospital were recruited in this study from July to December, 2020. Internal consistency, test-retest reliability, criterion validity, confirmatory factor analysis, and exploratory factor analysis were used to evaluate the reliability and validity of the Chinese version of Chronic Mucosal Diseases Questionnaire-15.
The total Cronbach's α of 0.841 and subscale ranging from 0.736 to 0.965 revealed good internal consistency of the reliability. The intraclass correlation coefficients exceeded 0.80 indicated excellent test-retest reliability. Compared with the Oral Health Impact Profile-14, the criterion validity was 0.549. The confirmatory factor analysis results supported acceptable validity of the Chinese version of Chronic Mucosal Diseases Questionnaire-15, and the exploratory factor analysis demonstrated that the 15 items were classified into four domains, with a cumulative proportion of 71.52%.
The Chinese version of Chronic Mucosal Diseases Questionnaire-15 is a brief and low-burden tool, and has been proved reliable and valid to assess the quality of life of patients with chronic oral mucosal diseases in China (the Chinese Clinical Trial Registry (no. ChiCTR2000031607).
慢性口腔黏膜疾病是一种常见的问题，严重影响个体的健康和社会功能。尽管已经有严格的中文版慢性黏膜疾病问卷（COMDQ-26）来衡量慢性口腔黏膜疾病患者的生活质量，但 26 个项目过于繁琐，给患者带来了负担。在中国，有必要制作一个简洁、实用、易用的工具。本研究旨在检验中文版短式慢性黏膜疾病问卷（COMDQ-15）的有效性和可靠性。
本研究共招募了 2020 年 7 月至 12 月来自一家三级口腔医院的 165 名受访者。采用内部一致性、重测信度、效标效度、验证性因子分析和探索性因子分析来评估中文版慢性黏膜疾病问卷-15 的可靠性和有效性。
总 Cronbach's α 为 0.841，各分量表范围为 0.736 至 0.965，显示出良好的可靠性内部一致性。组内相关系数均超过 0.80，表明重测信度极好。与口腔健康影响概况-14 相比，效标效度为 0.549。验证性因子分析结果支持中文版慢性黏膜疾病问卷-15 的有效性尚可，探索性因子分析表明，15 个项目分为四个领域，累积比例为 71.52%。
中文版慢性黏膜疾病问卷-15 是一种简洁、低负担的工具，已被证明在中国评估慢性口腔黏膜疾病患者生活质量时可靠且有效（中国临床试验注册中心（注册号 ChiCTR2000031607）。
