*2.4. Statistical Analysis*

The distribution of the variables was assessed using descriptive statistics. Independent *t*-tests and ANOVA evaluated the mean differences using participants' characteristics. A multiple linear regression model was performed to outline the factors associated with fear and anxiety of COVID-19. Adjusted beta-coefficient (β) and 95% confidence interval (95% CI) are reported for regression analysis. All analyses were performed using the statistical software package Statistica. A *p*-value of <0.05 was considered to be statistically significant.
