Note. T1 = Time 1; SE = Standard error; CI = Confidence interval; CM = Child maltreatment experiences latent factor; DEP = Depressive symptoms; ΔHRV = HRV residualized change score; ΔAlcohol = Alcohol use problems LC score; FIncome = Past-year household income. Gender was coded as 1 for male and 2 for female. Model fit for the mediation model: χ2 (63) = 113.603 (p <.001), CFI = .952, SRMR = .048. Model fit for the moderated mediation model: χ2 (77) = 130.200 (p < .001), CFI = .950, SRMR = .044.
