RESUMO
BACKGROUND: An early positive mother-child relationship is a central factor in the development of a psychologically balanced personality. The study aims to identify risk and protective factors for the development of a balanced maternal-infant postnatal attachment. We explored the association between maternal-infant attachment and prenatal and postnatal variables potentially implicated in the development of this early bond: maternal-foetal prenatal attachment, social support, memories of parental care, romantic attachment, dyadic adjustment, parity, breastfeeding, planning pregnancy, woman's and infant's age, and difficulty of delivery. METHODS: 123 pregnant women participated in the longitudinal study; they were assessed on the MAAS, PBI, ECR-R, MSPSS (t1: pregnancy), MPAS (t2: 3-months postnatally), DAS , and CES-D (t1, t2). RESULTS: Four significant predictors of maternal-infant postnatal attachment (MPAS) emerged: maternal-foetal prenatal attachment (ß = 0.379, p < .001), anxiety in the romantic relationships (ß=-0.237, p=0.019), prenatal and postnatal dyadic adjustment (t1, ß=-0.323, p=0.025 ;t2, ß=0.329, p=0.014) in the couple's relationship. These variables explained 20.2% of variance in mother-infant attachment (R2adjusted=0.202). DISCUSSION: The study highlights associations of maternal-infant postnatal attachment with prenatal and postnatal relational variables and with other variables related to the woman's reproductive and pregnancy history. Clinical attention to these factors could help protect the well-being of mother and child.
