Study Summary
Repeat testing for SARS-CoV-2 antibodies in disadvantaged communities will help identify active and recovered infections over time, and as more is understood about antibody protection, it may help identify persons who have immunity. Many questions about social barriers and behavioral facilitators remain unanswered. This project aims to evaluate the effectiveness of risk-based messaging and incentives that promote repeated testing for SARS-CoV-2 antibodies, as well as to understand social and behavioral determinants of COVID-19 testing and variations within sub-groups of this population.
Primary Outcome
Effectiveness of risk-based messaging and incentives to encourage attendance at Time 2 testing for SARS-CoV-2 antibodies
Interventions
- BEHAVIORAL Family Risk Messaging
- BEHAVIORAL Personal Risk Messaging
- BEHAVIORAL Loss Protection
