The actor–partner independence mediation model (unstandardized). All covariates, i.e., age, family income, and time spent on childcare, were included in the model (not shown). The R-squared values for wives’ and husbands’ depression were 0.311 and 0.263, respectively. Model fit statistics were as follows: Chi-square = 0.985; df = 1; p = 0.321; comparative fit index (CFI) = 1.000; Tucker–Lewis index (TLI) = 1.001; root mean square error of approximation (RMSEA) = 0.000; 90% confidence interval (90% CI) = (0.000–0.094); standardized root mean squared residual (SRMR) = 0.0037, * p < 0.05, *** p < 0.001.
