ABSTRACT
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.
ABSTRACT
Despite federal regulations mandating the inclusion of underrepresented groups in research, recruiting diverse participants remains challenging. Identifying and implementing solutions to recruitment barriers in real time might increase the participation of underrepresented groups. Hence, the present study created a comprehensive dashboard of barriers to research participation. Barriers to participation were recorded in real time for prospective participants. Overall, 230 prospective participants expressed interest in the study but were unable to join due to one or more barriers. Awareness of the most common obstacles to research in real time will give researchers valuable data to meaningfully modify recruitment methods.
ABSTRACT
BACKGROUND: Population reflective research enrollment improves study generalizability and disease knowledge. Nevertheless, the proportion of underrepresented groups (URGs) in Parkinson's disease (PD) research remains low. Hence, the current manuscript describes the process of designing a study to analyze the effectiveness of strategies to overcome barriers to URG recruitment in PD research. METHODS: The Fostering Inclusivity in Research Engagement for Underrepresented Populations in Parkinson's Disease (FIRE-UP PD) study asked participating sites to identify a URG or geographical region to target to assess knowledge and attitudes toward PD research as well as increase Fox Insight (an online study with The Michael J. Fox Foundation) participation across eight months. URGs were defined as racial and ethnic minorities, women, rural populations, and low socioeconomic status groups. Participating sites were paired based on their proposed interventions and were randomly assigned to either the intervention or control condition. RESULTS: The FIRE-UP PD study was divided into pre-intervention, intervention, and post-intervention periods to measure changes in awareness and trust in PD research along with engagement and interest in PD protocols through the use of several surveys. Interventions included developing educational tools to engage local communities, building partnerships within local PD communities, and recruiting stakeholders to reimagine medical and research information for the community. CONCLUSION: Improving representation in research is a crucial step toward improving access to PD diagnoses and treatments. This is one of the first multi-site PD research studies to include community engagement to address barriers to research participation and improve research recruitment of URGs.
