INTRODUCTION: Hispanic/Latino(a/x) (H/L) representation in Alzheimer's disease and related dementias (ADRD) research remains low, limiting generalizability of findings and interventions to this growing population. H/L community health workers ("Promotores") can enhance awareness of brain health and help guide their communities toward ADRD research opportunities; however, the effectiveness of recruitment through Promotores compared to traditional clinic-based approaches remains unknown. This study evaluates our Promotores training and compares the two approaches on recruitment success and characteristics of those recruited into a longitudinal study of ADRD.
METHODS: Nine Promotores completed Building Research Integrity and Capacity (BRIC) training on research concepts and ethics, and video training modules on ADRD-related research procedures. Training effectiveness was evaluated via pre-/post-tests to evaluate content knowledge and program satisfaction was evaluated by a self-report survey. Recruitment success was compared between Promotores-based and clinic-based approaches, assessing numbers referred and enrolled in ADRD research, and participants' demographic and clinical characteristics and agreement to specific research procedures (i.e., lumbar puncture, brain donation).
RESULTS: Promotores showed significant gains in knowledge of research concepts (Wilcoxon test, p = 0.005; median increase = 52%, 95% confidence interval [CI] = 30%-70%) and ADRD content (p = 0.042; median increase = 10%, 95% CI = 5%-40%). Promotores strongly agreed (on a 5-point Likert scale) that their training improved understanding of researcher responsibilities (x̄ = 4.88 ± 0.35), participant rights (x̄ = 4.25 ± 1.49), and ADRD research procedures (x̄ = 3.88 ± 1.36). Satisfaction with training materials (x̄ = 4.63 ± 0.74) and perceived community benefit (x̄ = 4.75 ± 0.46) were high. Promotores and clinic pathways had similar enrollment proportions (12.6% vs. 16.5%; Χ 2 = 0.92, p = 0.34) and participants were comparable across demographic, clinical, social determinants of health, and willingness to undergo research procedures.
DISCUSSION: The Promotores training program was well received, improved research literacy, and was as successful as clinic-based recruitment in enrolling older H/L adults into ADRD research. Results validate our Promotores training strategy and support a multipronged community-oriented approach to H/L participation in ADRD research.
