The Perceived Stress Scale (PSS) is a recognized diagnostic tool that is commonly used to measure stress levels, especially in research focused on the role of stress in the aetiology of diseases and behavioural disorders [31]. Orucu and Demir [32] recommended the use of this tool across different cultures and also in the student population. This tool consists of a 14-item scale, but its 10-item version is widely used in international studies examining students’ perceived stress [33,34,35,36,37]. A higher score generally indicates a higher perceived stress. In the Slovak Republic, the reliability and validity of this tool was verified by Ráczová et al. [38], who supported its use in a sample of the Slovak population. Last but not least, a 4-item version of PSS is also used, based on which Orosova et al. [39] revealed that 37.6% of Slovak students suffered from lower stress, approximately the same proportion (37.7%) suffered from moderate stress, and 24.7% of Slovak students experienced higher stress.
