Alcohol use among american college students in relation to need for cognition and expectations of alcohol's effects on cognition

Abstract

This article describes the development of a new self-report measure for assessing expectations for alcohol's cognitive effects and presents an empirical investigation of the association between cognitive alcohol expectancies and alcohol use. The present study also examined the potential moderating effects of need for cognition on the association between cognitive expectancies and drinking. Participants consisted of 179 college undergraduates from a midsized public university in the southeastern United States. Results of hierarchical multiple regression analyses, conducted separately for males and females, indicated several main effects for both cognitive alcohol expectancies and need for cognition on alcohol use. In contrast to these main effects, there were no significant multiplicative interaction effects, suggesting that need for cognition did not moderate the direction of association between cognitive expectancies and drinking. The results of homologizer/moderator analyses, however, did indicate a number of significant interaction effects for both males and females. These significant homologizer findings indicated that thestrength of association between cognitive alcohol expectancies and drinking increased as need for cognition increased. Implications of the present findings for future research are discussed.
