Being a Couple in the Context of Stepparenting: The Impact on Relationship Quality

While the harmonization of the relationships between biological parent and child, stepparent and stepchild is important to stepfamily functioning, relationship quality remains an important goal for many repartnered couples. Grounded in family systems theory, this study investigated, at the couple-level, the impact of both parenting and couple processes on the quality of the repartnered relationship. To better understand the experience of being a couple while stepparenting, we used a common fate model to analyze dyadic data from 759 repartnered couples involved in a statewide stepfamily intervention. This methodology explicitly focuses on the shared couple-level experience by capturing the shared source variance within the dyadic relationship, offering an alternative to models focused on individual interdependence. Structural equation modeling revealed that individual parenting behaviors mattered – specifically, the positive parenting processes of (step)mothers were positively, though weakly, associated with couple-level repartnered relationship quality. However, positive dyadic couple processes were a substantially larger predictor of relationship quality. These findings highlight that while navigating stepparenting is important, positive interpersonal interactions within the couple subsystem continue to play a vital role in the quality of a repartnered union.
