Alcohol use in the year before marriage: Alcohol expectancies and peer drinking as proximal influences on husband and wife alcohol involvement

Abstract

Background: Models of adolescent alcohol involvement that include individual difference, family, and peer risk factors indicate a significant association between the drinking of adolescents and that of their peers. Peer drinking influences, however, have not been investigated extensively in integrative models of adult drinking. The purpose of this study was to test a model of adult drinking that incorporated the potentially important risk factor of partner drinking and in which proximal risk factors (peer drinking, alcohol expectancies) were hypothesized to be strongly associated with adult alcohol use and to mediate relationships between more distal risk factors and drinking. Methods: Couples (n = 389) were assessed at the time of their first marriage. Separate, self-administered questionnaires were completed at home by both husbands and wives. Distal risk factors included family history of alcoholism, antisocial behavior, and depressive symptomatology. Substantive relationships were tested in a model that included spousal associations with respect to distal risk factors, proximal risk factors, and drinking. Results: Findings demonstrate the unique association of alcohol expectancies and peer drinking with adult alcohol use. Of particular relevance is the significance of the social network as a correlate of adult drinking. A peer network characterized by a higher level of alcohol involvement was strongly associated with heavier drinking among both men and women. This relationship was independent of sociodemographic and individual difference factors, alcohol expectancies, and partner's drinking. Results also demonstrate the similarity between husband and wife drinking, an association that cannot be attributed to assorting with respect to the other risk factors. Conclusions: The social network continues to significantly impact drinking behavior in adulthood. The relevancy of peer and partner drinking influences to adult alcohol involvement suggests that the immediate social environment may have a prominent role in the continuity/discontinuity of heavy or problem drinking during the transition to marriage.
