Dyadic Prenatal Coparenting Interaction Behaviors Predicting Postpartum Depressive Symptoms during the Transition to Parenthood.

Postpartum depressive symptoms constitute a common yet serious complication of pregnancy and childbirth, but research on its association with coparenting is scarce. Furthermore, although coparenting dynamics start forming prior to the child's birth, no research has explored dyadic prenatal coparenting dynamics as a predictor of postpartum depressive symptoms. The current study assessed how dyadic prenatal coparenting behaviors predicted postpartum depressive symptoms in first-time parents. We conducted a dyadic mixed-method longitudinal study of 107 expectant couples with data collected prenatally, and at 3, 6, and 24 months post-birth. The results indicated that prenatal coparenting dyadic synchrony predicted low levels of depressive symptoms among first-time fathers 3 and 6 months after the birth, and a prenatal coparenting dynamic of dyadic negative escalation predicted high levels of depressive symptoms among first-time mothers at 3 and 24 months postpartum. The theoretical and practical implications are discussed.
