Parental problem drinking and children's adjustment: family conflict and parental depression as mediators and moderators of risk.

We examined marital conflict, parent-child conflict, and maternal and paternal depression symptoms as mediators and moderators in the associations between fathers' and mothers' problem drinking and children's adjustment. A community sample of 6-12-year-old boys and girls and their mothers, fathers, and teachers participated. Marital conflict, parent-child conflict, and maternal depression symptomatology each functioned as a mediator of the association between father's problem drinking and children's externalizing and internalizing problems, and maternal depression symptoms accounted partially for the link between father's problem drinking and children's social problems. For mother's problem drinking, marital conflict, parent-child conflict, and maternal depression symptoms each mediated the association with children's externalizing problems. Further, parent-child conflict explained partially the link between mother's problem drinking and internalizing problems, and marital conflict accounted for the association between mother's problem drinking and social problems. When the mediators were simultaneously examined, parent-child conflict was the most robust mediator of the association between parental problem drinking and externalizing problems, and maternal depression symptomatology was the most consistent mediator of the relation between parental problem drinking and internalizing problems. Further, parent-child conflict and paternal and maternal depression symptoms each interacted with parental problem drinking to moderate some domains of children's adjustment. The significant moderation effects indicate that parent-child conflict is a robust vulnerability factor for internalizing problems.
