DATA SOURCES: Secondary analysis of linked survey sample frame and administrative data, including demographic and health-related information. STUDY DESIGN: The survey was administered by mail with telephone follow-up to nonrespondents after two mailings. To determine whether an additional mail contact or mode switch reduced nonresponse bias, we compared all respondents (N = 3,437) to respondents from each mailing and telephone respondents to the sample frame (N = 6,716). PRINCIPAL FINDINGS: Switching modes did not minimize the under-representation of younger people, nonwhites, those with congestive heart failure, high users of office-based services, and low-utilizers of the emergency room but did reduce the over-representation of older adults. CONCLUSIONS: Multiple contact and mixed-mode surveys may increase response rates, but they do not necessarily reduce nonresponse bias.<p> 10.1111/j.1475-6773.2011.01369.x Deployment of a mixed-mode data collection strategy does not reduce nonresponse bias in a general population health survey Demography Telephone Health Services Research document-rn19674 Data Collection 13846 47 22272 2022-02-21T22:48:57.408-06:00 Questionnaires 4 public
