Bidirectional associations between maternal depression, hostile parenting, and early child emotional problems: Findings from the all our families cohort

•Maternal depression predicted subsequent child internalizing problems•Hostile parenting mediated the intergenerational transmission of affective disorders•Child internalizing symptoms predicted subsequent hostile parenting•Effects were moderated by child levels of effortful control An intergenerational association between maternal depression and child emotional problems is well established. However, the underlying processes underpinning this association are still unclear, with relatively little attention paid to potential child-driven effects. This study adds to existing research by examining the bidirectional processes between maternal depression, parenting, and child internalizing symptoms. A large prospective pregnancy cohort was used (N = 1992). Mothers reported on their depressive symptoms, hostile parenting, child internalizing symptoms, and child effortful control. Data was collected during pregnancy, and at 4 months, 3 years, and 5 years postpartum. Using a cross-lag analytical approach, results revealed that prenatal and postpartum maternal depression predicted child internalizing problems through an increase in hostile parenting. Child internalizing symptoms predicted increases in subsequent hostile parenting, but not maternal depressive symptoms. Additional moderation analyses revealed that the indirect effect of maternal depression on child internalizing problems through hostile parenting was only significant for children low in effortful control. The study relied on maternal reports of both mother and child symptomology and characteristics. The sample was predominantly white and middle- to high-income. Hostile parenting is a potential intermediary mechanism explaining the intergenerational transmission of maternal depression to child internalizing problems. Critically, this indirect effect was only significant for children low in effortful control. There was limited support for child evocative effects, with child internalizing symptoms predicting subsequent hostile parenting but not maternal depressive symptoms. Results highlight the need for considering both maternal and child characteristics when treating maternal depression.
