Chronic oral mucosal disease uestionnaire (COMDQ) is used to evaluate the quality of life in patients with chronic conditions of the oral mucosa. The aim of the present study was to evaluate the validity and reliability of the Persian version of this questionnaire.
A total of 135 subjects were selected in two groups; group 1 consisted of 95 patients with chronic oral mucosal conditions, including recurrent aphthous stomatitis, oral lichen planus and pemphigus and mucous membrane pemphigoid and group 2 consisted of 40 patients with other oral diseases. The subjects completed the demographic data sheets and COMDQ and then underwent examinations to determine disease severity. After 14 days, the questionnaire was completed again by the group 1subjects only.
Cronbach's α coefficient for COMDQ was estimated at 0.969 and the interclass correlation coefficient was estimated at 0.997. There was a significant relationship between the mean COMDQ scores and disease and pain severity. There was a clear correlation between the patients' self-report about their general health and mean COMDQ scores and also between their opinions about their oral health and the mean COMDQ scores.
The Persian version of COMDQ exhibited proper levels of reliability and validity. It is suggested that this questionnaire be used for the evaluation of the effect of treatment on the oral health-related quality of life (OHQoL).
慢性口腔黏膜疾病问卷（COMDQ）用于评估慢性口腔黏膜疾病患者的生活质量。本研究的目的是评估该问卷波斯语版本的有效性和可靠性。
共选取135名受试者分为两组；第1组由95名患有慢性口腔黏膜疾病的患者组成，包括复发性阿弗他口炎、口腔扁平苔藓、天疱疮和黏膜类天疱疮，第2组由40名患有其他口腔疾病的患者组成。受试者填写人口统计学数据表和COMDQ，然后接受检查以确定疾病严重程度。14天后，仅第1组受试者再次填写问卷。
COMDQ的Cronbach's α系数估计为0.969，组内相关系数估计为0.997。COMDQ平均得分与疾病及疼痛严重程度之间存在显著关系。患者对自身总体健康状况的自我报告与COMDQ平均得分之间以及他们对口腔健康的看法与COMDQ平均得分之间存在明显相关性。
COMDQ波斯语版本表现出适当水平的可靠性和有效性。建议使用该问卷评估治疗对口腔健康相关生活质量（OHQoL）的影响。
