Mediating effect of health behavior change on PTSD symptoms. This table presents the coefficients from ordinary least squares regression models of PTSD score on COVID-19–related worry, attention to news, and stress from social distancing as well as the indicated health behavior changes. Age, male sex, Hispanic race, income <US $80,000, income US $81,000-100,000, unemployed, and underlying medical condition were included as covariates in all models.
