In this area of research, many international studies deal with the stress of students of medical disciplines, making them a special category. The 10-item PSS tool was also often used in these studies, and it can be stated that medical students reported moderate levels of stress [40]. In the Russian study [41], medical and dental students acquired a mean score of 16.97, with gender and socio-economic status playing a significant role in the differences in scores. Polish medical students obtained a mean PSS score of 22.78 [42]. In another international study of nursing students, Slovak, Polish, and Spanish students reported similar mean values for the 10-item PSS score, which indicated moderate stress (the Slovak Republic = 18.66, Poland = 18.60, Spain = 18.55) [43]. In this context, there is evidence that medical students have a higher risk of stress compared to non-medical students [44]. On the other hand, the evidence shows that the 10-item PSS score differs not only in fields of study, but also in various countries. Based on the mean PSS scores obtained in international studies, moderate to
