Fostering Inclusivity in Research Engagement for Underrepresented Populations in Parkinson's Disease: The FIRE-UP PD study.

Background: Members of vulnerable populations are underrepresented in Parkinson's disease (PD) research. A complex web of research barriers perpetuates this gap. Community-based research methods are one approach to addressing this issue. The present PD study was designed to examine the effectiveness of community-based interventions to overcome barriers and increase research participation among underrepresented groups (URGs).
Methods: Eight study sites across the US were selected and paired based on proposed interventions with specific URGs. Surveys assessed knowledge and attitudes toward PD research. Finally, researchers examined whether the present study affected recruitment to Fox Insight, an online PD research study also recruiting at each site.
Results: In total, 474 participants were recruited. At post-intervention for the FIRE-UP PD Study, recruitment increased significantly in intervention compared to control sites among Black and African American non-Hispanic/Latino populations (p = 0.003), White Hispanic/Latino (p = 0.003) populations, and Not Listed Hispanic/Latino populations (p < 0.001) as well as those with an educational attainment of a high school diploma/General Education Diploma (GED) (p = 0.009), and an income <$20,000 (p = 0.005) or between $20,000-$34,999 (p < 0.001). Study surveys measuring changes in awareness and attitudes toward PD research had mixed results. In Fox Insight, 181 participants were passively recruited with a shift toward more diverse participant demographics.
Conclusion: Research participation demographics reflective of the general population are critical to PD investigation and treatment. The FIRE-UP PD Study showed the effectiveness of localized community engagement strategies in increasing URG recruitment to PD research. Therefore, further PD research employing community-based methods to improve diverse participant recruitment is needed.
