Association between maternal-infant bonding and depressive symptoms in Neonatal Intensive Care Unit mothers: A case-control study.

OBJECTIVES: Maternal perinatal depression has been associated with impaired mother-infant bonding. The adverse effect of this impaired bonding has been reported. This study aimed to investigate and compare the posnatal depressive symptoms and the mother-infant bonding in a Neonatal Intensive Care Unit (NICU) and of mothers with healthy newborns respectively. Secondly, was to explore the association between depressive symptomatology and bonding in both groups.

METHODS: In this case study, mothers in the early pospartum period who gave birth in the same perinatal center of Greece were recruited to participate. The cases consisted of 88 mothers of neonates who were hospitalized in the NICU and controls were 100 mothers of full-term healthy neonates. For the collection of the data questionnaires including demographics and perinatal variables were used. For the bonding and posnatal assessment, the Mother to Infant Bonding Scale, the Postpartum Bonding Questionnaire, and the Hospital Anxiety and Depression Scale were used.

RESULTS: There was a significant difference between the mean of bonding scores of NICU mothers and the control group (t = -2.696, P = 0.008). NICU mothers presented lower scores in bonding with the newborn compared to the control group and presented higher depression scores compared to those of controls (χ2  = 28.588, P = 0.000). The depression scores were correlated with bonding scores in both groups.

DISCUSSION: A NICU admission has an impact on bonding and in some way interacts with maternal pospartum mental health, therefore more research is needed.

CONCLUSIONS: NICU mothers have been presented as more vulnerable than mothers of healthy infants since they expressed a lower mother-infant bonding and higher depression scores. The support of these vulnerable mothers and the facilitation of mother-infant bonding by the NICU staff is of utmost importance.
