The development of self-reported measures of periodontal disease would be of great benefit to facilitate epidemiological studies of periodontal disease on a larger scale, and to allow for surveillance of the periodontal condition of populations over time.
To develop a culturally adapted self-reported measure of periodontal disease, test its predictive and discriminative validity and establish a cut-off value for this measure to diagnose periodontal disease.
A total of 288 Jordanian adults completed the questionnaire assessing self-reported periodontal health (18 questions) and underwent periodontal examination. Of the 18 questions, six were significantly associated with at least one clinical definition of periodontitis and were used to constitute the self-reported periodontal disease measure. Receiver-operating characteristics (ROC) curve analyses were used to examine the overall discriminatory power, sensitivity and specificity, and corresponding cut-off points of the self-reported periodontal disease measure.
ROC analysis showed that the self-reported periodontal disease measure had an excellent performance to discriminate between those with and without periodontal disease, regardless of the clinical definition used. A score of 2, on a scale of 0 to 6, had the highest sensitivity and specificity to detect periodontal disease when defined by all study criteria. Significant associations were observed between self-reported periodontal disease measures and all clinical definitions in the regression analysis (the odds ratio ranged from 8.31 to 18.96), according to the clinical definition to be predicted.
Self-reported periodontal disease measures have excellent predictive and discriminative validity when tested against clinical definitions, and severity and extent of periodontal disease.
开发牙周疾病的自我报告测量方法将极大有助于推动大规模的牙周疾病流行病学研究，并能够对人群的牙周状况进行长期监测。
开发一种经过文化调适的牙周疾病自我报告测量方法，测试其预测效度和区分效度，并确定该测量方法诊断牙周疾病的临界值。
共有288名约旦成年人完成了评估自我报告牙周健康状况的问卷（18个问题），并接受了牙周检查。在这18个问题中，有6个问题与牙周炎的至少一种临床定义显著相关，被用于构成自我报告牙周疾病测量方法。采用受试者工作特征（ROC）曲线分析来检验自我报告牙周疾病测量方法的总体区分能力、敏感性和特异性以及相应的临界点。
ROC分析表明，无论使用何种临床定义，自我报告牙周疾病测量方法在区分有牙周疾病和无牙周疾病者方面表现出色。在0至6分的量表上，当根据所有研究标准定义牙周疾病时，得分为2分时检测牙周疾病的敏感性和特异性最高。在回归分析中，根据要预测的临床定义，观察到自我报告牙周疾病测量方法与所有临床定义之间存在显著关联（优势比范围为8.31至18.96）。
与临床定义、牙周疾病的严重程度和范围进行对照测试时，自我报告牙周疾病测量方法具有出色的预测效度和区分效度。
