Interactions between parents and children establish norms for managing emotions and behavior, which are markers of resilience. This study examines how features of interpersonal communication between parents and children facilitate the resilience of children of alcoholic parents versus nonalcoholic parents. Parent–adolescent dyads (30 families of alcoholics, 30 families of nonalcoholics) were invited to participate in two videotaped interactions, which were then rated for parental responsiveness and control and adolescent emotion regulation and behavioral impulsivity. Parental responsiveness was positively associated with emotion regulation, and parental control was negatively associated with emotion regulation and positively associated with impulsivity. Moderation analyses point to several notable differences in the effects for alcoholic versus nonalcoholic families.
