* p < 0.05; ** p < 0.01; *** p < 0.001.
a Depressive symptoms were measured by the PHQ-9.
b Variables that were significant in bivariate analyses were entered as independent variables in the multilevel regression analysis.
c The coefficients were small and below two decimals.
d Intra-class correlation within family was 0.12 for both PHQ-9 and PHQ-6.
