COVID-19 behavior determinants dataset.

The COVID-19 Behavior Determinants Database (http://covid19-database.com) is a research project that examined the sociodemographic and psychological determinants of COVID-19 related attitudes and behaviors. It is a comprehensive web-based survey that was administered to adults ages 18 or older (total n=8070) from the United States of America (n = 5326), including the four most populous states, specifically New York, California, Florida, and Texas, and Canada (n = 2744), including all provinces, except Quebec. The survey was collected at three timepoints, May 2020 (n=1019), July 2020 (n=4027), and March 2021 (n=3024). Participants provided detailed sociodemographic information and completed a battery of psychological assessments. Participants also provided information about prior testing for COVID-19 and perceived seriousness of COVID-19 and the need for current physical (social) distancing restrictions. The database is helpful to researchers and public health policy decision-makers who are interested in investigating and identifying the determinants of COVID-19 related attitudes and behaviors in North America.
