Respondent-driven sampling to recruit Latinos in a midwest micropolitan area: Lessons learned and recommendations for translational work

Abstract

Latinos constitute a hard-to-reach minority population in Iowa. We used respondent-driven sampling (RDS) to supplement random digit dialing to recruit Latinos for a community physical activity intervention. RDS yielded a 59% increase in Latino participation in just 2 months, with few demographic differences between RDS and random digit dialing groups. RDS may increase recruitment of underrepresented populations and strengthen community engagement; however, it is not a quick fix for underperforming recruitment methods.
