Compared with the pre-lockdown period, students reported higher stress (median [IQR]; 16 [13, 18] vs. 23 [18, 26.3]; *p* < 0.001), moderate-to-severe anxiety (median [IQR]; 4 [2, 8.3] vs. 10 [5, 15]; *p* < 0.001), and moderate-to-severe depression (median [IQR]; 3 [1, 6] vs. 10 [4, 15]; *p* < 0.001) during the lockdown. Similarly, more students experienced high stress (4.1% vs. 24.7%), moderate-to-severe anxiety (19.4% vs. 55.2%), and moderate-tosevere depression (12.9% vs. 51.5%) during the lockdown (Figure 1).

**Figure 1.** Poor mental health status before and during COVID-19 lockdown (*N* = 173). Black bars and white bars represent the poor mental health status before and during the COVID-19 lockdown, respectively. High stress = Perceived Stress Scale scores ≥ 27; moderate-to-severe anxiety = GAD-7 scores ≥ 10; moderate-to-severe depression = PHQ-9 scores ≥ 10.
