The effects of familial risk, personality, and expectancies on alcohol use and abuse

This study tested a structural model of the association between familial risk, personality risk, alcohol expectancies, and alcohol abuse in a sample of 224 young adult offspring of alcoholics and 209 offspring of nonalcoholics. The results provided support for 2 personality-risk pathways, a social deviance proneness and an excitement/pleasure seeking path, that accounted for a significant portion of the association between a familial alcoholism and alcohol abuse, The path from familial alcoholism to social deviance proneness lead directly to alcohol problems. The path from familial alcoholism to excitement/pleasure seeking was associated with increased drinking, which, in turn, was associated with alcohol problems. Positive alcohol expectancies accounted for part of the association between excitement seeking and alcohol use; The results suggest 2 different biopsychosocial mechanisms that elevate risk for abuse in the offspring of alcoholics.
