Including Socially Isolated Black, Older Old Adults (Aged 80 and Above) with and without Mild Cognitive Impairment in a Clinical Trial: Recruitment Strategies and Perspectives

Abstract

Objective: This study describes strategies for the recruitment of socially isolated older old Black individuals to participate in the “Internet-based conversational engagement clinical trial (I-CONECT)” (Clinical Trial.gov: NCT02871921) and lessons learned in this critical population segment. Methods: Best practice strategies to recruit the target population included mass mailings, advertisements, and direct community outreach, including the collaboration with a community group created to reach Black individuals interested in research participation. We also made protocol changes to measure recruitment criteria for older old Black adults more accurately and to increase their participation. Results: Descriptive data related to the challenges and successes in recruiting Black participants compared to the White participants is presented. The primary site contacted 17,523 primarily White potential participants and enrolled/randomized 145 White and 2 Asian/ mixed race participants (0.8%). The Midwest site contacted 12,141 Black potential participants and enrolled/randomized 39 (0.3%) participants. Discussion: While best practices were employed, several factors complicated recruitment, including the need to adjust recruitment criteria, navigate regional regulations, and respect diverse community preferences. Conclusion: Older old African Americans are reachable and willing to participate in research when considering their beliefs and practices, influenced by their community and experience.
