Preventive Behaviors during the COVID-19 Pandemic in Delaware’s Underserved Communities: A Longitudinal Study (2021–2022)

The COVID-19 pandemic officially started in March 2020 and ended in May 2023. Preventive behaviors have been proven to be one of the most effective strategies for preventing COVID-19 transmission. Common preventive behaviors against COVID-19 include but are not limited to wearing a face mask, washing and sanitizing one’s hands frequently, avoiding crowds, and avoiding traveling. Underserved communities and racial/ethnic minorities across the U.S. have been disproportionately affected by the COVID-19 pandemic. Using a three-wave longitudinal survey conducted from early 2021 to late 2022, the present study investigated changes in the adoption of COVID-19-preventive behaviors among residents living in Delaware’s most underserved communities. We also examined whether changes in COVID-19-preventive behaviors differed by race. Our results indicated that fewer people adopted preventive behaviors as the pandemic progressed, and this finding is applicable to both Black people and White people. However, Black people had a consistently greater likelihood of adopting preventive behaviors compared to White people from early 2021 to late 2022. Scientific and policy implications are discussed.
