The structural model of mother-infant bonding in the first pregnancy based on the mother’s attachment style and parenting style: the mediating role of mentalization and shame

INTRODUCTION: This study aimed to evaluate the relationship between the mother’s attachment style and parenting style and mother-infant bonding in the first pregnancy considering the mediating role of mentalization and shame. METHODS: This was a descriptive-correlational study. The sample population included the women who had gone through their first pregnancy and were referred to the health centers in Neyshabur, Iran in 2022. In total, 330 women were selected by convenience sampling. To collect data, we used a demographic questionnaire, the Attachment Style Questionnaire, the Parenting Style Questionnaire, the Mother-Infant Bonding Scale, the Reflective Functioning Questionnaire, and the Guilt and Shame Proneness Scale. Data analysis was conducted using descriptive indices, correlation coefficients, and pass analysis. RESULTS: Overall, the findings showed that the studied model adequately fits the data. Further, the obtained results confirmed the mediating role of mentalization and shame in the relationship between the mother’s attachment style and parenting style and mother-infant bonding. A significant correlation was also observed between attachment styles, parenting styles, and mother-infant bonding (p < 0.01). CONCLUSION: Mother-infant bonding is correlated with the mother’s attachment style/parenting style, shame, and mentalization. Thus, we can help vulnerable mothers by improving the quality of psychological care before the first pregnancy or during pregnancy.
