Recent studies have noted a decline in the response rates of random-digit-dialing (RDD) surveys. To increase participation and improve representation of the general population, the Behavioral Risk Factor Surveillance System (BRFSS) piloted several follow-up projects in 2012. These projects included a mail follow-up study for landline phone numbers in 10 states (CT, KS, NH, IL, MA, MO, MT, ND, OH, and AR), a Web-based follow-up (WBFU) for landline phone numbers in 7 states (CT, DE, ,HI, IA, KY, NE and Washington DC) and a text invitation to Web follow-up for cell phone numbers in one state (CT). The purpose of the follow-up pilots was to test the feasibility of using landline/cell phone nonresponse contacts and their impact on demographic and health characteristics of respondents. All three pilots followed standardized protocols using specific non-responding RDD disposition codes to identify potential follow-up respondents. For landline follow-ups, phone numbers were matched to address and either entire surveys (for the mail follow-up) or letters with Web site links and login information (for WBFU) were sent to the household. Cell phone non-respondents with the same RDD disposition codes were texted and directed to the Web-site. Data collection will continue through December 2012. Results will be presented to illustrate unweighted differences in the characteristics of respondents of the three follow-up formats, as well as those who responded to the BRFSS. Preliminary data for the first nine months (N=1,107) from Web-based follow up survey indicate that it can increase the participation of female and Asian non-Hispanic respondents as well as those who have college degrees and annual household incomes of over $75,000 or more. Single-adult households are also more likely to participate in the Web-based follow-up survey.
