Relationship between childhood trauma and postpartum psychotic experiences: the role of postnatal anxiety and depression as mediators.

Background: Postpartum psychosis (PP) is a psychological emergency requiring rapid intervention, hospitalization and psychiatric management. However, PP has been neglected in the postpartum literature. Understanding the detrimental consequences of childhood trauma across mother's life span is crucial to prevent this serious condition. The study's objectives were to demonstrate the relationship between childhood trauma and postpartum psychotic experiences (PPEs) and to look over the mediating role of postnatal depression (PD) and anxiety (PA) in this relationship.

Methods: This cross-sectional study, which enrolled 438 postpartum females 4-6 weeks after delivery (mean age: 31.23 ± 5.24 years), was carried out from September 2022 to June 2023. The Arabic validated versions of the Postpartum Psychotic Experiences Scale, the Edinburgh Postnatal Depression Scale, the Perinatal Anxiety Screening Scale, and the Child Abuse Self Report Scale were used.

Results: Both PD and PA partially mediated the correlation between psychological abuse and PPEs, and fully mediated the association between neglect and PPEs. Higher psychological abuse and neglect were significantly associated with higher PD (Beta = 1.11) and PA (Beta = 3.94), higher PD (Beta = 0.84) and PA (Beta = 0.26) were significantly associated with higher PPEs in both models, whereas greater child psychological abuse (Beta = 1.37) (but not neglect) was directly and strongly correlated with higher PPEs in all models.

Conclusion: The significant mediating effect of PA and PD on the association between childhood adversities and PPEs among postpartum females may offer additional therapeutic avenues to help attenuate various postpartum mental health issues and their potential serious risks on both mother and child.
