Abstract:

The precipitous decline in RDD response rates in recent years is forcing researchers to reconsider the design of RDD-based studies and surveillances. This presentation provides results from a set of experiments conducted in five states, administering the Behavioral Risk Factor Surveillance System (BRFSS) in three modes: web, mail, and CATI. Comparisons are made between the regular, monthly CATI-only results and self-administered web with CATI follow-up and self-administered mail with CATI follow-up alternatives. We examine differences in response rates, the types of sample members responding to each mode, and potential biases in the estimates obtained across modes.
