The Effectiveness of Community-based Outreach Events for the Promotion of African American Research Participation.

introductionAfrican Americans (AA) are disproportionately affected by Alzheimer's disease and related dementias yet are under-represented in clinical research. Outreach events for AA are offered to encourage research participation; however, this approach's effectiveness remains largely unexplored.

methodsTo explore the effectiveness of AA-focused versus general audience events, the authors examined attendance data over 5 years, encompassing 10 general audience events and 4 events focused on AA. For each individual, the authors searched center records for recruitment contacts and research enrollment. Summary scores for attendance at AA-focused events, general audience events, and total events were compared between those with and without research involvement.

resultsOut of 773 unique AA that attended ≥1 event, 88 became or were involved in research (11.4% engagement). AA-focused events achieved greater AA attendance than general audience events. Although research-engaged individuals were more likely to have ever attended an AA-focused event than a general audience event, attendance at AA-focused events did not statistically relate to research engagement. In contrast, attendance at events focused on the general public was related to an increased likelihood of research participation. DISCUSSION: These findings have important implications for designing and implementing community events to encourage AA research participation.
