The importance of personalismo: Navigating obstacles in recruitment strategies for Spanish speakers in marginalized communities.

Recruitment obstacles with Spanish-speaking individuals and members of marginalized communities have been documented in the literature in narrative form, but quantitative data on effective strategies are limited. Within our research protocol assessing the impact of a storytelling intervention on knowledge and uptake of cell-free DNA (cfDNA) aneuploidy screening, three different recruitment strategies were trialed and enrollment rates were compared. Throughout the study, field notes were collected from observations in recruitment efforts. We demonstrate the effectiveness of language-concordant, personal interactions, and culturally tailored materials for recruitment of Spanish-speaking participants into genomic research studies. We also offer commentary on the experience of the researchers that provides insights to inform recruitment methods for marginalized communities.
