Dyadic Analysis of Cumulative Childhood Trauma and Relationship Satisfaction: The Role of Parental Alliance

Abstract

Cumulative childhood trauma (CCT) increases the risk of relationship difficulties in adulthood. Couples welcoming a new child are particularly prone to relationship distress, and CCT survivors may be especially vulnerable during this period. This study examined the association between CCT and relationship satisfaction and tested the role of parental alliance in this association. A random sample of 1136 different-gender parental couples completed online self-report questionnaires. Path analyses guided by the Actor–Partner Interdependence Model revealed that parents' CCT was associated with their own lower relationship satisfaction through their own and their partner's parental alliance in both mothers and fathers. Results also revealed dyadic associations between one parent's CCT and their partner's relationship satisfaction through their own and their partner's parental alliance. These findings support the relevance of couple interventions focusing on the parental alliance to improve relational well-being in parental couples where one or both partners have experienced CCT.
