Abstract:

Address-based sampling (ABS) has emerged as a promising alternative to RDD telephone surveys. Little is known about the effectiveness of the various procedures for contacting the households and administering ABS surveys in reducing potential nonresponse bias. This paper is based on an ABS study involving two phases of data collection. Mail was the primary mode of collection for each phase, with limited telephone follow-up and several experiments designed to explore the effect on the response. Using the level-of-effort analysis, we examine how the response rates, demographic and socio-economic characteristics, and key survey estimates change with the screener follow-up attempts. The results compare the extent to which the screener follow-up strategies increased the effective coverage of the target subpopulation and affected the estimates in a two-phase survey setting.
