背景资料：网络和邮件调查作为电话调查的补充可能有助于解决对公共卫生监测电话调查参与率下降的担忧。鲜为人知的是，然而，如何在网络调查中获得的答复比较那些从邮件或电话surveillance.Methods：行为危险因素监测系统2003年的核心访谈进行了3种调查模式：网络（n = 1143），邮件（n = 836），电话（n = 2072）。所有3个样本均随机抽取。我们比较了受访者的人口统计学和回答8个关键问题的健康状况和危险行为（包括哮喘，糖尿病，肥胖，艾滋病病毒检测）在3个调查models.Results：邮件和网络受访者的人口特征差异很大，从那些通过电话采访。结果的未调整患病率因调查模式而异。在对受访者的人口统计学特征进行调整后，在几种健康状况和危险行为方面，调查模式之间仍然存在差异，尽管对于其中一些，未调整和调整结果的模式是不同的。随着健康调查利用新技术并转向混合模式设计，研究人员需要测试，如果必要的话，在他们产生的估计中考虑众数的影响。
Background: Web and mail surveys as complements to telephone surveys may help resolve concerns about declining participation in telephone surveys for public health surveillance. Little is known, however, about how responses obtained in Web surveys compare with those from mail or telephone surveys.Methods: The Behavioral Risk Factor Surveillance System 2003 core interview was conducted in 3 survey modes: Web (n = 1143), mail (n = 836), and telephone (n = 2072). All 3 samples were drawn randomly. We compared respondent demographics and responses to 8 key questions on health conditions and risk behaviors (including asthma, diabetes, obesity, and HIV testing) across the 3 survey modes.Results: Demographic characteristics of mail and Web respondents varied considerably from those interviewed by telephone. The unadjusted prevalence of outcomes varied by survey mode. After adjustment for respondent demographic characteristics, there were still differences among survey modes in several of the health conditions and risk behaviors, although for some of these, the pattern was different for the unadjusted and adjusted results.Conclusions: As health surveys take advantage of new technologies and moved towards mixed-mode designs, researchers need to test for and, if necessary, account for the effect of mode in the estimates they produce.
