RESUMO
The COVID-19 pandemic has challenged existing health communication strategies as more people turn to social media as a primary health information source. Although many studies have explored how young people use social media, this study examined how sociodemographic factors and political ideology are associated with use and trust in social media as a source for COVID-19 information among young adults, and how use and trust in social media as a COVID-19 information source are associated with their beliefs about COVID-19. In Spring 2021, an online survey was conducted among 2,105 18-29-year-old students at an urban university in California. Our findings show that younger, female, non-binary, Asian, and Black/African American students are most likely to obtain and trust COVID-19 information on social media. Results also suggest that liberal students are more likely to turn to social media as a source for COVID-19 information compared to conservatives. However, conservative students who use social media as a source for information were more likely to believe false health information about prevention measures and the vaccine and to have lower perceived effectiveness of COVID-19 prevention behaviors and vaccination compared to liberals.
