Secondary outcome measures (maternal functioning): Standardized parameter estimates (and standard errors), t and p values, and 95% confidence intervals of multilevel models of intervention outcome predicted by measurement point (T2 and T3, deviations from T1), group [intervention (reference) and waitlist control group], control variable (PHQ-4 score at T1), and interaction variables (group by T2 and T3).
