1. Investigators track and report enrollment rates stratified by race/ethnicity, related challenges, and solutions. |
2. Investigators conduct nested studies of the effectiveness of recruitment or retention within other health research studies. |
3. Funding opportunity announcements for primary data collection studies include a request for investigators to incorporate a nested study that compares the effectiveness of multiple methods of recruitment and/or retention, especially studies that include underrepresented groups. |
4. Funding agencies appropriate targeted funding to investigate specific methodologically challenging recruitment issues, e.g., identifying alternative incentives for recruiting groups that have been discriminated against or that are impoverished in longitudinal cohort studies that may have limited funding to pay monetary incentives to participants. |
