Recruitment of Minorities Using Address-Based Sampling (ABS): A Pilot Study
Abstract:
The crisis in coverage of the landline telephone frame has reached a point where researchers are testing alternatives to (or at a minimum, complements to) traditional landline random digit dialing (RDD). Ideally, a new sampling methodology would address not only the coverage challenges posed by cell phone only households and unlisted households in zero-listed banks, but also provide a basis for developing survey designs that could address the growing nonresponse issue which also plagues traditional RDD approaches. One such approach proven to be promising and potentially cost effective involves use of address-based samples using large comprehensive databases, such as the U.S. Postal Service Delivery Sequence File (DSF). The Gallup Panel, which uses traditional landline-based RDD methodology to recruit its members, conducted a pilot study involving the use of the USPS DSF as an address-based sampling alternative to RDD for recruiting Black and Hispanic panel members. The sampling procedure for this study involved identifying census block groups (BC) with 50% or more Black/Hispanic households in Nebraska, creating geographic strata based on the number of city-style addresses within each BC, and selecting addresses randomly from each stratum to ensure a systematic random selection. The sampled addresses were then divided into treatment groups based on a 2 x 2 experimental design where the mode of panel recruitment (Web/mail) and sending a postcard reminder were experimentally manipulated. Preliminary findings reveal a minimal impact of the reminder postcard on panel recruitment response rate and skewed (gender (female) and education (low)) demographic makeup of recruited panel members. This paper discusses the findings from this study and concludes with recommendations for future work.
