This study assesses the reliability of a self-reported health questionnaire completed by 413 subjects aged 25-74 yr in the Erie County Periodontal Disease (ECPD) Study. Specific questions on general and oral health conditions were completed by each subject during a first visit and at a follow-up examination 2 yr later, and the two compared. Results showed that the overall measure of agreement between the two visits is substantial (average kappa, kappa = 0.80). Variation by gender and age were minimal. Questions regarding allergy to medications, oral treatment, reason for tooth extraction, health symptoms and history of systemic diseases exhibited high levels of agreement (kappa ranged from 0.71-0.90). Information on vitamin and mineral intake yielded kappa = 0.63. Oral conditions scored the lowest but were still acceptable (kappa = 0.57). These findings indicate that there were no significant discrepancies in self-reported responses to the health questionnaire used in the ECPD Study. Although the information provided by the subject may not be as accurate as compared to laboratory testing, it is nevertheless a reliable source of information which can be utilized cost-effectively in research studies.
本研究评估了在伊利县牙周病（ECPD）研究中，413名年龄在25至74岁之间的受试者填写的一份自我报告健康问卷的可靠性。每位受试者在首次就诊时以及2年后的随访检查中填写了关于一般健康状况和口腔健康状况的具体问题，并对两者进行了比较。结果显示，两次就诊之间的总体一致性度量很高（平均卡帕值，kappa = 0.80）。性别和年龄的差异极小。关于药物过敏、口腔治疗、拔牙原因、健康症状和全身疾病史的问题显示出高度一致性（kappa值范围为0.71 - 0.90）。维生素和矿物质摄入量的信息得出的kappa值为0.63。口腔状况得分最低，但仍可接受（kappa = 0.57）。这些发现表明，在ECPD研究中使用的健康问卷的自我报告回答中没有显著差异。尽管受试者提供的信息可能不如实验室检测准确，但它仍然是一个可靠的信息来源，可以在研究中经济高效地加以利用。
