Previous studies have suggested that positive urgency, positive and negative alcohol expectancies, and working memory (WM) capacity may affect college students’ excessive alcohol consumption, not only independently but interactively as well. The purpose of this study was to test a hypothetical model in which positive alcohol expectancy would moderate the relationship between positive urgency and alcohol consumption, whereas negative alcohol expectancy would demonstrate significant moderating effect only when WM capacity is sufficient. Participants were 179 college students with drinking experience, and data from 164 students who met the response accuracy criteria for the WM capacity task were analyzed using hierarchical regression analysis. Results indicated that positive urgency predicted alcohol consumption for individuals with high positive alcohol expectancy, and WM capacity did not moderate such interactions. Negative alcohol expectancy did not moderate the relationship between positive urgency and alcohol consumption, regardless of WM capacity. This study contributes to existing literature by examining the integrative effects of multiple risk factors on college students' excessive alcohol consumption, which were separately investigated in most previous studies. Furthermore, clinical implications and limitations of the study are discussed.
