Notes. Pearson correlations are displayed below the diagonal; Spearman correlations are displayed above the diagonal. All correlations are statistically significant at p < 0.001, except the correlations involving sex and age, of which none are statistically significant (all ps > .05). ODI: Occupational Depression Inventory; DASS-21-D: Depression subscale of the Depression Anxiety Stress Scales-21; M: mean; SD: standard deviation. Sex was coded “0” for female and “1” for male.
