Comparison of response rates and cost-effectiveness for a community-based survey: postal internet and telephone modes with generic or personalised recruitment approaches

摘要

BackgroundEpidemiological research often requires collection of data from a representative sample of the community or recruitment of specific groups through broad community approaches. The population coverage of traditional survey methods such as mail-outs to residential addresses, and telephone contact via public directories or random-digit-dialing is declining and survey response rates are falling. There is a need to explore new sampling frames and consider multiple response modes including those offered by changes in telecommunications and internet technology.
