Knowledge, attitudes and practices related to COVID-19 in the U.S.

Given the urgent need for data to inform public health messaging to mitigate the spread of the COVID-19 pandemic, this national survey sought to assess the state of COVID-19-related knowledge, beliefs, mental health, substance use changes, and behaviors among a sample of U.S. adults. A survey of U.S. adults was administered online from March 20-30, 2020. The survey collected data on socio-demographic characteristics; COVID-19-related knowledge, awareness and adoption of preventive practices; depression and anxiety (assessed by the Patient Health Questionnaire-4); stress (adapted Impact of Event Scale-6); pessimism; and changes in tobacco and alcohol use.
