Notes: Beta, standardized partial regression coefficient; VIF, variance inflation factor. Dependent variable: PHQ-9 summary score. Nine independent variables: age, sex (men = 0, women = 1), marital status (single = 0, married = 1), presence of offspring (no = 0, yes = 1), living alone (no = 0, yes = 1), education years, CATS total score, EPQ-R neuroticism score, victimization score. Adjusted R2 = 0.36; F = 35.962; p < 0.001.
