In order to provide more detailed information on the PSS and PHQ 9 outputs and their link to the AUDIT score, Table 3 shows the arithmetic mean and median of the AUDIT score in each combination of the PSS and PHQ 9 intervals. Based on the results, it can be observed that lower values of the AUDIT score were attributed to the intervals with a lower level of mental disorders (PSS, PHQ 9) and vice versa (Mean: PSS–Low and PHQ 9–None = 5.54; PSS–High and PHQ 9–Severe = 9.35). At the same time, there were some deviations from this trend, for example in the combination of PSS–Moderate and PHQ 9–None (Mean = 5.20; Median = 4.00).
