我们探索的相关性，在互联网上进行的健康和退休研究（HRS）的一部分，在美国50岁及以上的人的小组研究调查的非覆盖和无反应。大约30%的HRS受访者表示他们使用互联网。其中，73%的人表示愿意进行网络调查。随后，这一组的一个子集被发送了一封邮件邀请参加一个网络调查，78%的人完成了调查。使用多变量模型，我们发现显着的人口，财务和健康相关的差异，在访问，与其他研究一致。在意愿（有机会）和反应（有意愿）方面的差异较小。然而，在控制了覆盖面和反应方面的人口差异之后，健康和社会经济地位方面的差异仍然存在。因此，在这类调查中，仅对人口统计数据进行加权不太可能产生具有代表性的样本。在这一年龄组的互联网调查中，未覆盖（无法上网）似乎比未答复（即使有上网机会也不愿意参与）更令人关切。(c)2005年爱思唯尔公司All rights reserved.
We explore the correlates of noncoverage and nonresponse in an Internet survey conducted as part of the Health and Retirement Study (HRS), a panel study of persons 50 years old and older in the US. About 30% of HRS respondents indicated they used the Internet. Of these, 73% expressed willingness to do a Web survey. A subset of this group was subsequently sent a mailed invitation to participate in a Web survey and 78% completed the survey. Using multivariate models, we find significant demographic, financial, and health-related differences in access, consistent with other research. There are fewer differences in willingness (given access) and response (given willingness). However, disparities in health and socio-economic status persist after controlling for demographic differences in coverage and response. Weighting on demographics alone is thus unlikely to yield a representative sample in such surveys. Noncoverage (lack of access to the Internet) appears to be of greater concern than nonresponse (unwillingness to participate given access) for representation in Internet surveys of this age group.
