Multiple Logistic regression. Dependent variables: CBCL (internalizing, withdrawn and anxious depressed). Independent variables (0 is used as a reference level): EPDS (0 ≤ 9, 1 ≥ 10), Life Events and LSS (0 < 90th percentile, 1 ≥ 90th percentile), Parental unemployment (0 = both parents employed, 1 = one or both parents unemployed), Parental immigration status (0 = both parents born in Sweden, 1 = one or both parents born abroad)
