6.1.1. Total DASS Score

The total DASS score for the entire group of the respondents was 38.13 ± 26.51, which was lower than the cut-off score equal to 60, proposed by Lovibond and Lovibond [41]. The overall emotional distress was statistically higher (*p* < 0.001) in females (M = 40.54 ± 26.65) compared to males (M = 31.60 ± 25.02). The results showed that there was a relationship between the field of study and the DASS total score; the highest score was observed in science students (median (Me) = 42.00 ± 40.91), the second in turn was in the case of the participants studying arts and humanities (Me = 39.00 ± 28.98), social sciences (Me = 35.00 ± 28.14), and engineering (Me = 32.00 ± 26.79). The lowest score was obtained amongst the respondents who studied medicine (Me = 31.00 ± 25.48). Based on the Kruskal–Wallis test, the studied groups were statistically different (H = 16.16, *p* = 0.0028). The highest difference was noted between the medical and science students (z = 3.312, *p* = 0.009) (Supplementary Table S1). There were no statistical differences between the first-year students and the rest of the respondents in the DASS total score, as well as in none of the subscales (depression, anxiety, and stress).

#### 6.1.2. Depression

The mean score for the depression subscale for the entire study group was 14.04 ± 10.44, which can be classified as a moderate level of depressive symptoms. The intensity of depression defined as normal in the DASS-21 subscale concerned 43.6% (*n* = 948) of the total group of students. The mild intensity of depression applied to 13% (*n* = 282) of the examined students, moderate to 19.9% (*n* = 432), severe to 10.2% (*n* = 221), and extremely severe to 13.3% (*n* = 289). The level of depression in the female group (M = 18.41 ± 14.05) was significantly higher (*p* < 0.001) than in males (M = 12.24 ± 14.37). The results obtained from the Kruskal–Wallis test showed no significant difference between the students' field of study and the level of depression (Supplementary Table S1.2).
