Mistrust of the government and medical research and limited transportation are two of the individual barriers that influenced the study design and led us to create and deploy the MRVs in the community as research platforms. Before we moved the MRVs to each neighborhood, the recruitment team educated potential participants on the value of medical research in general and the specific benefits of participation in the HANDLS study. When our field interviewers made their door-to-door recruitment visits, MRVs in the neighborhood were instrumental at putting residents at ease and encouraging further dialogue. Trust was established in part by providing the field interviewers with formal identification badges with the study logo displayed prominently.
