Parents' hostility in dyadic marital and triadic family settings and children's behavior problems.

The authors examined the relation between parents' hostility during conflict-focused discussions and child behavior problems. Parents engaged in 3 discussions: a dyadic marital discussion of marital disagreements, a dyadic marital discussion of child-related disagreements, and a triadic family discussion with the child about the child-related disagreements. Eighty-nine 2-parent community families with a child aged 9-13 years participated. A significant 3-way interaction between interparental hostility, parent-to-child hostility, and child sex accounted for variance in children's behavior problems. Among boys, higher levels of parent-to-child hostility during family discussions exacerbated the effects of interparental hostility on boys' adjustment. Thus, exposure to higher levels of both interparental and parent-to-child hostility may put boys at risk for developing internalizing and externalizing behavior problems.
