Improving Health Equity for COVID-19 Vaccination for At-risk Populations Using Online Social Networks

Study Summary

Social technologies for health have already become essential means for providing underserved populations greater social connectedness and increased access to novel health information. However, these technologies have also had negative unintended consequences. The resulting digital divide in social technology takes many forms - from explicit racism that excludes African American and Latinx populations from the resources enjoyed by White and Asian members of online communities, to self-segregation for the purposes of identity preservation and community-building that unintentionally results in limited informational diversity in underserved communities. The result is an often unnoticed, but highly consequential compounding of inequities. This research seeks to use an online social network approach to address these challenges, in which the investigators demonstrate how reducing the online levels of network centralization and network homophily among African American community members directly increases their productive engagement with health-promoting information.

Primary Outcome

COVID-19 vaccination attitude scale, which is a self-reported scale measuring participants' attitudes toward COVID-19 vaccination. The scale is consisted of 5 questions (e.g., "How much confidence do you have that the COVID-19 vaccine in the U.S. is safe and effective?") with responses ranging from 1 (No confidence at all) to 5 (A great deal of confidence); a higher average score means a more positive attitude in favor of COVID-19 vaccination.
