Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Recent data have shown that covid19 is disproportionately infecting and killing African Americans and Latinx people in the United States. The aim of the study is to determine which messages are most effective at increasing knowledge and changing behaviors that can protect individuals and their communities from the virus. To accomplish this aim, we plan to recruit approximately 20,000 Hispanic and African-American individuals and randomly assign them to videos that vary either the sender or the framing of the message, while providing the relevant public health information.
