Lessons learned from witnessing constructive interparental conflict and the beneficial implications for children.

= 4.38 years; 52% female children; 28% Black; 14% multiracial or other race; 16% Latinx) and their mothers. The methodological approach consisted of multiple methods and informants in a longitudinal design with three annual measurement occasions (i.e., preschool, kindergarten, first grade). Results of the path analysis indicated that Wave 1 constructive IPC predicted residualized increases in children's emotion situation knowledge and social problem solving at Wave 2 with the inclusion of hostile IPC, demographic factors, and prior child characteristics (i.e., child age, race, internalizing and externalizing symptoms, social competence) as simultaneous predictors. In turn, children's emotion situation knowledge at Wave 2 predicted residualized decreases in their internalizing and externalizing symptoms at Wave 3. Wave 2 social problem solving also predicted residualized increases in their social competence at Wave 3. Results are discussed in the context of how they advance developmental models of constructive family conflict. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
