Study performed and analysis done by healthcare professionals. Published by an official United States website.
"fear and worry of COVID-19 increased statistically significantly more among healthcare than non-healthcare workers" (Sasaki)
"In particular, after adjusting the covariates, psychological distress and its subscale of fatigue, anxiety, and depression increased statistically significantly more among HCW compared to non-HCW during the COVID-19 outbreak." (Sasaki)
"This longitudinal study provides more compelling evidence that the mental health of HCW declined during the COVID-19 outbreak, not just because of their prior working conditions" (Sasaki)
