COVID-19 related worry moderates the association between postpartum depression and mother-infant bonding

Abstract

The aim of this study was to ask whether a substantial external stressor, such as the COVID-19 pandemic, affects the association between postpartum depression (PPD) and mother-infant bonding. Specifically, we aimed to determine whether worry regarding such an external threat differentially affected PPD and bonding by analyzing a longitudinal sample of postpartum women assessed before and during the pandemic. One-hundred forty women responded to online questionnaires at (T1) Pre-COVID-19: Six months postpartum (February 2018 to December 2019), and (T2) During COVID-19: Twenty-one months postpartum (April 2020 to January 2021). The strength of correlation between mother-infant bonding and PPD significantly declined from before (T1: R = 0.64, p < 0.00) to during the pandemic (T2: R = 0.44, p < 0.001; Difference = 0.20, p = 0.05). Furthermore, only PPD correlated with the worry due to the pandemic; thus the PPD-bonding association was weaker among women who were less concerned about the pandemic (F(3, 136) = 15.4, R² = 0.25). The study suggests that emotions and cognitions related to motherhood, such as mother-infant bonding, may be more resilient to external pressures such as a pandemic than affective states such as PPD.
