Disproportionate access to health information and resources by marginalized groups is one indicator of health inequity and disparity in the United States. Further, the composition of an individual’s social networks is a strong predictor for their health outcomes and behaviors. Social media has expanded the traditional idea of a social network, allowing people in different places in the world to form connections. Chioma is studying how these online relationships, and subsequent exposure to health-related information and misinformation, influence health behaviors. With a focus on black populations, Chioma hopes that her research will inform policy that addresses issues with health literacy and health behavior interventions.

The Effect of Source Credibility on Promising Message Themes: A Message Pretesting Study to Address COVID-19 Vaccine Hesitancy among Black Americans
Vaccination against the novel coronavirus is the prioritized approach to ending the COVID-19 pandemic, however there is vaccine hesitancy across different subgroups of the U.S. population. Focusing on hesitancy among Black Americans, this dissertation seeks to investigate a strategy to increase COVID-19 vaccination through public messaging efforts across three studies. The goal of the research is to provide evidence to inform the development of public health communication efforts to address the disparity in COVID-19 vaccine uptake, which can also inform other risk communication efforts in future public health crises.
