Abstract
BACKGROUND: College students who consume caffeinated alcoholic beverages (CaffAlc) are at increased injury risk. This study examines the extent to which a sensation-seeking personality accounts for the relationship between consumption of CaffAlc and negative outcomes. METHODS: A Web-based survey was administered to stratified random samples of 4907 college students from eight North Carolina universities in Fall 2009. Sensation seeking was assessed using the Brief Sensation-Seeking Scale (BSSS) (α=0.81). Data were analyzed using linear and logistic regression. RESULTS: 3390 students (71.2%) reported past 30-day drinking, of whom 786 (23.2%) consumed CaffAlc. CaffAlc past 30-day drinkers had higher BSSS scores (3.8 vs. 3.4; p<0.001), compared to non-CaffAlc drinkers. Consumption of CaffAlc was associated with more frequent binge drinking (p<0.001) and drunken days in a typical week (p<0.001), even after adjusting for the BSSS score. CaffAlc students were more likely to be taken advantage of sexually (adjusted odds ratio [AOR]=1.70, p=0.012), drive under the influence of alcohol (AOR=2.00, p<0.001), and ride with a driver under the influence of alcohol (AOR=1.87, p<0.001). Injury requiring medical treatment was more prevalent among CaffAlc students with higher BSSS-8 scores (interaction p=0.024), even after adjustment for drinking levels and student characteristics. CONCLUSIONS: Sensation seeking does not fully account for the increase in risky drinking among college students who consume CaffAlc, nor does it moderate the relationship between CaffAlc and drinking behaviors. Sensation seeking moderates the risk of alcohol-associated injury requiring medical treatment among college students who consume CaffAlc. Those with strong sensation-seeking dispositions are at the highest risk of alcohol-associated injury requiring medical treatment.
