Studied role of adolescents' awareness in relationship between marital conflict and adolescent distress. Found marital conflict was related to parental hostility toward adolescents and adolescents' awareness of conflict; parental hostility and adolescents' awareness of marital conflict were related to adolescent-perceived parental hostility. Found that when controlling for earlier distress, perceived parental hostility predicted later internalizing and externalizing symptoms. (KB)
