Statistical analyses:
We used descriptive statistics in the form of percentages to present the sociodemographic and educational characteristics of the students in addition to their prevalence rates of depression, anxiety, and stress during the COVID-19 pandemic. Logistic regression analyses were conducted to determine the associating factors, in the form of odds ratios (ORs) and confidence intervals (CIs), with depression, anxiety, and stress symptoms. The mild to moderate and severe to very severe forms were merged in each psychological condition to obtain statistical power. P-values of less than 0.05 were considered significant. Data were analyzed using the Statistical Package for Social Science (SPSS) released in 2013 (IBM SPSS Statistics for Windows, Version 22.0, IBM Corporation, Armonk, New York).
