The difficulty in screening households to complete interviews in random-digit dialing surveys has increased over time. An alternative strategy to relying solely on RDD numbers is to supplement the sample with numbers selected from directory listings. List frames can increase the incidence rate of targeted subgroups by reducing out of scope numbers, add demographic information on households from secondary databases and improve the effectiveness of advance mailings. To assess the impact of combining listed and RDD numbers on efficiency and survey results, we use data from a statewide survey of adults and a national survey of youth 12 - 17 and young adults 18 - 24. Both studies focused on smoking behavior and attitudes and used a dual-frame sample with directory-listed and RDD numbers. For both studies, we compare the two sample frames and completed interviews from each frame on key indicators to see if and how the results differ. This research addresses the potential of dualframe techniques to reduce effort and provide accurate survey data.
