Factors affecting mother-infant bonding in a Polish group of mothers

The study aimed to identify the factors affecting the mother-infant bond.

This cross-sectional study included 117 mothers of infants up to 12 months of age. The participants completed online versions of the Postpartum Depression Screening Scale - Short Form, the Postpartum Bonding Questionnaire, the Parenting Sense of Competence Scale, the Perception of Stress Questionnaire, and the Prenatal Expectations Scale, which included expectations toward the child, social functioning, and the partner. The results were analyzed using independent t-tests, one-way ANOVA, and multivariate linear regression.

Mothers who experienced symptoms of postpartum depression reported lower satisfaction with motherhood, higher stress levels, and greater discrepancies between prenatal expectations and postpartum reality. Regression analysis revealed that postpartum depression symptoms did not significantly influence the three dimensions of bonding difficulties. However, stress, discrepancies between expectations toward the partner and child, and maternal sense of competence were found to potentially intensify bonding disorders. The study also found that greater disappointment with the partner was generally associated with a weaker bond with the child. However, in cases where caring for a child was more challenging than expected during pregnancy, high emotional tension was present, or the mother had lower parental competencies, having a partner who functioned better than expected may exacerbate the disruption of the bond between the mother and child.

Prenatal expectations, perceived stress levels, and maternal sense of competence are significant factors in bonding difficulties, with postpartum depression symptoms being an important as single variable. However, the role of postpartum depression symptoms in shaping the mother-infant bond diminishes when the overall functioning of the mother is considered.
