A multivariate analysis of covariance was conducted to examine the possible effects of demographic variables (i.e., gender as an independent variable, and educational level, living place, employment status, and age as covariates) on the outcome variables (all mediators and outcome variables in the SEM model). Results showed that gender differences were not significant in terms of any research variable. Educational level and age had significant effects on some of the mediators and outcome variables (see Supplementary Material).
