The relations of children's coping strategies and coping efficacy to parent socialization and child adjustment were examined in a sample of school-age children that included families in which some of the grandparents and/or parents had an alcoholism diagnosis. Parents and older children reported on the children's coping strategies; parents reported on their parenting behavior; and teachers reported on children's externalizing and internalizing problems. Measures of parent socialization were associated with parents' and children's reports of active coping strategies and parents' reports of both support-seeking coping and coping efficacy. Some of these relations were moderated by familial alcohol status. Children higher in parent-reported active/support-seeking coping and coping efficacy were rated lower in teacher-reported externalizing and internalizing adjustment problems. The findings were consistent with the view that active/support-seeking coping and coping efficacy mediated the association of parent socialization to children's psychological adjustment and that this relation was sometimes moderated by parental alcohol status.
