of the PHQ 9 score on the AUDIT score. The presented facts were also confirmed by the results of correlation analysis, on the basis of which it was possible to observe significant positive correlation rates, which indicate a significant to very strong association for PSS and PHQ 9 and a low to moderate association for PHQ 9 and AUDIT. All of these findings are consistent with the findings of many international studies focusing on the mental and behavioural disorders of university students and the identification of their perceived stress, depression, and alcohol use disorders using the PSS, PHQ 9, and AUDIT tools. Specifically, Kaya [56] and Zajenkowska et al. [57] confirmed that the PSS score of university students is a significant predictor of depression measured by the PHQ 9 diagnostic tool. Our findings on the relations between depressive disorder and alcohol use disorder can also be compared with other studies, in which a significant correlation between the AUDIT score and the PHQ 9 score was confirmed [88,89]. In response to these findings, mental health was a major predictor of alcohol use disorders.
