Recruiting a Prospective Community Cohort to Study Alzheimer’s Disease

Background

Black older adults are underrepresented in Alzheimer’s disease research. Researchers at Washington University in St. Louis examined methods used to recruit and retain Black older adults in an ongoing study of Alzheimer’s disease and the social conditions that affect health.  

Findings

During the first 22 months, 629 people expressed interest and 238 enrolled in the study. Word-of-mouth referrals (snowball sampling), community events, and speaking engagements were the most effective recruitment methods.
