The moderated mediation model for the UGS, happiness and socioeconomic indicators. (a) Scatter plot of social support and the UGS across countries. (b) Diagram for the moderated mediation model. The boxes denote the model variables. Solid black arrows denote a statistically significant relationship between a pair of variables with the regression coefficient and the p-value (i.e., ∗∗∗\(p<0.01\)). The gray dashed arrow represents a non-significant relationship. Note that the coefficients are calculated with z-scores of the variables to compare the effect size directly
