Background: Rural communities were disproportionately impacted by the COVID-19 pandemic. Current and future pandemic preparedness in rural areas could be aided by serological (antibody) testing. However, benefits to be gained from serosurveillance are challenged both by the accessibility of serological testing resources in hard-to-reach rural areas, and by likely hesitancy towards their use in many rural communities. Trials are needed to evaluate outreach and health communication strategies that can increase rural receptivity towards serosurveillance. Methods: We conducted a two-arm randomized controlled trial that recruited N = 194 participants from rural northern Michigan. In a single online session lasting approximately 45 min, participants were randomly assigned to view either a general SARS-CoV-2 antibody testing didactic video, or a rural targeted didactic video co-created with a rural community advisory board and containing unique rural messaging. Primary self-report outcomes included receptivity to antibody testing, as well as activation of medical mistrust and concern for rural-discrimination in future SARS-CoV-2 antibody testing. We also developed and provided an opportunity to participate in a home-based salivary antibody screening program. In addition to assessing the feasibility and fidelity of this program, we assessed interest and full participation in the serosurveillance program as behavioral outcomes. Discussion: Findings from this study can guide the use of home-based screening programs and targeted health communication strategies to promote greater uptake of health resources in rural communities. In doing so, study results can also guide public health strategies to reduce pandemic-related and other rural health disparities.
