Stigma, Post-traumatic Stress, and COVID-19 Vaccination Intent in Mongolia, India, and the United States.

: Stigma and discrimination during the coronavirus (COVID-19) pandemic have increased precipitously worldwide. This multinational study examines how stigma, blaming groups for virus spread, concern regarding contracting the virus, resource loss, life satisfaction, and protective behaviors that help control the spread of COVID-19 are associated with post-traumatic stress and vaccine intent in Mongolia, India, and the United States. : 1429 people in Mongolia, India, and the United States completed measures assessing stigma during the COVID-19 pandemic, post-traumatic stress, blame, protective behaviors, and vaccine intent. : Mean post-traumatic stress scores in all three countries exceeded the cut-off that is commonly used to determine probable post-traumatic stress. Post-traumatic stress was associated with COVID-19 stigma experience, personal behavior change due to COVID-19 stigma, blaming groups for the spread of COVID-19, fear of COVID-19, and resource loss. In India and the United States, personal behavior change due to COVID-19 stigma, anger at individuals spreading COVID-19, and perceived susceptibility to illness were positively associated with vaccine intent. : Stigma is a collateral stressor during the pandemic. The findings underscore the importance of prompt action to address stigma as a deleterious consequence of the pandemic. The findings illuminate potential barriers to receiving the vaccine and provide direction for future research to address barriers.
