The importance of high-quality partner support for reducing stress during pregnancy and postpartum bonding...

The current study investigated the extent to which interparental support reduced pregnancy stress and subsequent postpartum bonding impairments with infant. We hypothesized that receiving higher quality partner support would be associated with decreased maternal pregnancy-related concerns, and less maternal and paternal pregnancy stress which, in turn, would predict fewer parent-infant bonding impairments. One hundred fifty-seven cohabiting couples completed semi-structured interviews and questionnaires once during pregnancy and twice postpartum. Path analyses with tests of mediation were employed to test our hypotheses. Higher quality support received by mothers was associated with lower maternal pregnancy stress which, in turn, predicted fewer mother-infant bonding impairments. An indirect pathway of equal magnitude was observed for fathers. Dyadic pathways also emerged such that higher quality support received by fathers was associated with lower maternal pregnancy stress which reduced mother-infant bonding impairments. Similarly, higher quality support received by mothers reduced paternal pregnancy stress and subsequent father-infant bonding impairments. Hypothesized effects reaching statistical significance (p < .05) were small to moderate in magnitude. These findings have important theoretical and clinical implications in demonstrating the critical role of both receiving and providing high-quality interparental support to reduce pregnancy stress and subsequent postpartum bonding impairments for mothers and fathers. Results also highlight the utility of investigating maternal mental health in the couple context.
