The Mediating Role of Postpartum Depression and Childbirth-related PTSD in the Relationship Between Attachment Styles and Postpartum Bonding Among Mothers in Ahvaz City, Iran

Objective: Several studies have explored the correlation between postpartum depression and a weak mother-infant bond; however, fewer studies have analyzed how other postpartum mental health conditions, such as childbirth-related post-traumatic stress disorder (PTSD), or important personal characteristics, including adult attachment styles, affect the quality of the mother-infant bond. This study aims to examine the association between attachment styles and postpartum bonding in mothers, considering the mediating influence of postpartum depression and childbirth-related PTSD. Methods: A total of ۱۵۰ mothers, ۴ to ۱۲ weeks postpartum, completed a demographic questionnaire, the Edinburgh postpartum depression questionnaire, the posttraumatic stress questionnaire related to the birth of a child, the mother-child bonding questionnaire, and the attachment style questionnaire. The posttraumatic stress related to the birth of a child questionnaire was translated into Persian for the first time and was used after confirming its validity and reliability. The proposed model was examined by the structural equation modeling method. Results: The conceptual model’s results showed that the direct and standardized effect of anxious attachment style (β=۰.۴۹, P=۰.۰۰۱) and avoidant attachment style (β=۰.۴۷, P=۰.۰۰۱) on postpartum depression were significant. Also, the direct effect of anxious attachment style (β=۰.۵۹, P=۰.۰۰۱) on postpartum PTSD was significant. However, the coefficient of avoidant attachment style (β=-۰.۰۴, P=۰.۵۸۱) was not significant for postpartum PTSD. Also, the coefficients were investigated from the direct effect of postpartum depression, postpartum PTSD, anxious attachment style, and avoidant attachment style. The obtained results showed that postpartum depression (β=۰.۲۷, P=۰.۰۰۱), postpartum PTSD (β=۰.۴۳, P=۰.۰۰۱), and anxious attachment style (β=۰.۳۹, P=۰.۰۰۱) could predict the mother-child bond. However, the avoidant attachment style (β=۰.۰۰, P=۰.۹۴۶) could not predict the mother-child bond. Conclusion: The findings of the study revealed that insecure attachment styles were linked to challenges in forming a strong mother-infant bond. Anxious attachment was also associated with bonding difficulties, which were influenced by symptoms of postpartum depression and childbirth-related PTSD. In contrast, a higher degree of avoidant attachment style was associated with more significant difficulties in bonding, which were mediated by symptoms of depression. Accordingly, if interventions aim to enhance the mother-infant bond, treatment should focus on addressing childbirth-related PTSD, PPD symptoms, and insecure attachment styles.
