Coparenting Problems and Parenting Behavior as Mediating Links Between Interparental Conflict and Toddlers' Adjustment Difficulties in Germany.

Objective: Interparental conflict has long been acknowledged as a major risk factor for the well-being of children. Empirical studies reveal clear associations between children's maladjustment and frequent destructive conflicts between their parents (van Eldik et al., 2020). Existing research suggests that interparental conflict spills over from the couple to the coparental relationship, undermining parents' skills to cooperate and their parenting competencies. This study addresses the effects of interparental conflict on the behavioral and emotional problems of toddlers. Methods: The analyses were based on longitudinal data from the German Family Panel pairfam. The sample comprised information on N = 828 anchor participants (59.9 % female) and their 3- to 5-year-old children. Results: As expected, the effects of interparental conflict on children's behavioral and emotional problems were mediated by coparenting problems and in part also by negative parenting. Further analyses comparing mothers and fathers revealed a stronger direct path of interparental conflict on coparenting for mothers. Conclusions: The findings provide support for the significance of the interparental relationship and coparenting quality for child development, even in this young age group, and point to the importance of early prevention.
