Mother-to-infant bonding mediates the effects of depressive and anxious postpartum symptoms on parenting stress

A number of studies have suggested close associations between maternal postpartum mental health (depressive and anxious symptoms), mother-infant bonding, and parenting stress. However, the relationship between maternal bonding and parenting stresshas hardly been explored in published literature. This cross-sectional study explored whether maternal bonding could mediate the effect of postpartum maternal mental health on parenting stress. This study assessed maternal bonding (MPAS), depressive and anxious symptoms (EPDS; STAI), and parenting stress (PSI) at 3 months postpartum in a community sample of 105 women (M (SD) = 32.60 (4.18) years old). Spearman's correlation analyses showed moderate to high correlations between these factors. The three mediation models run showed that mother's MPAS partially mitigates the effects of EPDS (b = 0.71; SE = 0.217; 95% CI = 0.290/1.136) and STAI State (b = 0.39; SE = 0.113; 95% CI = 0.178/0.625) on PSI, and totally mediated the relationship between STAI Trait and PSI (b = 0.59; SE = 0.155; 95% CI = 0.303/0.912). Maternal bonding resulted to be a relevant factor in the association between maternal mental health and parenting stress. This highlights the importance of interventions focusing on mother-infant relationship to reduce parenting stress and prevent developmental difficulties in children.
