The most frequently used method to request and collect health-related information has been the mail questionnaire. While self-administered surveys offer a relatively low-cost and convenient method for collecting health data, they have been unpopular among researchers because of concerns about low response rates and nonresponse bias. This study examines differences in demographic and health characteristics between mail survey respondents and nonrespondents who were subsequently interviewed by telephone. Subjects for this study had at least one health care encounter in 1990 from a Medicare-waiver program. The telephone survey was conducted approximately two months after the last wave of a three-wave mailing survey of this urban elderly population. No significant differences were found between telephone and mail respondents for demographic, socioeconomic, quality of life, or perceived oral health characteristics. However, mail respondents were more likely to be dentate and report better perceived general health than were the telephone respondents.
获取和收集健康相关信息最常用的方法是邮寄调查问卷。虽然自填式调查为收集健康数据提供了一种相对低成本且便捷的方法，但由于担心低回复率和无应答偏差，它们在研究人员中并不受欢迎。本研究调查了邮寄调查问卷的受访者与随后通过电话访谈的未受访者在人口统计学和健康特征方面的差异。本研究的受试者在1990年至少有一次来自医疗保险豁免计划的医疗保健接触。电话调查是在对该城市老年人群体进行的三轮邮寄调查的最后一轮之后大约两个月进行的。在人口统计学、社会经济、生活质量或感知口腔健康特征方面，电话受访者和邮寄受访者之间未发现显著差异。然而，邮寄受访者比电话受访者更有可能有牙齿且报告的总体健康状况更好。
