Couple, Parent, and Infant Characteristics and Perceptions of Conflictual Coparenting over the Transition to...

This study examined trajectories of new parents' perceptions of conflictual coparenting and predictors thereof. Partners in 182 dual-earner different-gender U.S. couples reported their prenatal marital conflict and individual characteristics (conflictual coparenting in the family of origin, parenting self-efficacy expectations, and parenting role beliefs) during the third trimester of pregnancy, their infant's characteristics (negative affectivity and gender) at 3 months postpartum, and their perceptions of undermining coparenting and exposure to conflict at 3, 6, and 9 months postpartum. Results of latent growth curve models indicated that new parents' perceptions of undermining, but not exposure to conflict, increased similarly from 3 to 9 months. Fathers perceived higher initial undermining than mothers, but there were no gender differences in exposure to conflict. For mothers, greater prenatal marital conflict and greater infant negative affectivity were associated with elevated levels of perceived undermining and exposure to conflict. For fathers, more egalitarian role beliefs were associated with lower undermining and less exposure to conflict, whereas greater prenatal marital conflict, higher conflictual coparenting in the family of origin, and greater infant negative affectivity were associated with greater exposure to conflict. Fathers also perceived greater undermining and exposure to conflict when mothers reported higher prenatal marital conflict, whereas mothers' greater conflictual coparenting in the family of origin was related to fathers' lower exposure to conflict. These findings provide valuable information to strengthen programs focused on improving coparenting.
