Associations between coparenting relationships and maternal depressive symptoms and negative bonding to infant

Abstract

Maternal mental illnesses during early postpartum may be caused by lack of the copar-enting relationship parents share and cooperate regarding child-rearing. This study clarifies the association of the coparenting relationship and negative mental health of mothers at one and three months after childbirth. This study conducted a secondary analysis of data from an intervention study wherein 24 mothers rearing their first child with a cohabitant (husband/partner) participated. Maternal mental health was evaluated using the Edinburgh Postnatal Depression Scale to determine postpartum depressive symptoms and the Mother-to-Infant Bonding Scale to assess negative bonding. Mothers’ average age was 31.5 ± 4.2 years old. All mothers were not working during the research period. The prevalence of postpartum depression and bonding disorder were approximately 13% and 21%, respectively. A better coparenting relationship was associated with lower postpartum depressive symptoms at both one month (β = −0.617, p = 0.002) and three months (β = −0.709, p < 0.01) postpartum. In contrast, no association was found between a coparenting relationship and negative bonding. The results indicate that the coparenting relationship may possibly prevent maternal depression during the early postpartum period.
