Binge drinking on university campuses is associated with social and health-related problems. To determine the factors that may predict this behavior, we collected information on alcohol use, alcohol expectations, and impulsivity from 428 undergraduate students attending a Canadian university. The subjective effects of a binge drinking dose of alcohol were assessed in a subset of participants. In the larger sample, 72% of students reported drinking at or above binge drinking thresholds on a regular basis. Men reported alcohol consumption per drinking occasion, which was consistent with other studies, but the frequency of drinking occasions among women was higher than in earlier studies, suggesting that consumption in women may be increasing. Compared with men, women reported different expectations of alcohol, specifically related to sociability and sexuality. Self-reported impulsivity scores were related, albeit weakly, to drinking behaviors and to expectations in both the sexes. Finally, intoxicated binge drinkers reported feeling less intoxicated, liking the effects more, and wanting more alcohol than did non-binge drinkers receiving an equivalent dose of alcohol. These results have implications for sex-specific prevention strategies for binge drinking on university campuses.
大学校园里的酗酒行为与社会及健康相关问题有关。为了确定可能预测这种行为的因素，我们收集了428名就读于一所加拿大大学的本科生的饮酒情况、对酒精的期望以及冲动性方面的信息。在一部分参与者中评估了一次酗酒剂量酒精的主观影响。在更大的样本中，72%的学生报告称经常饮酒达到或超过酗酒阈值。男性报告每次饮酒场合的饮酒量，这与其他研究一致，但女性饮酒场合的频率高于早期研究，这表明女性的饮酒量可能在增加。与男性相比，女性报告了对酒精的不同期望，特别是与社交性和性方面有关。自我报告的冲动性得分与饮酒行为以及两性的期望都有关联，尽管关联较弱。最后，与接受等量酒精的非酗酒者相比，醉酒的酗酒者报告感觉醉酒程度较轻，更喜欢这种效果，并且想要更多的酒精。这些结果对大学校园酗酒行为的针对性别预防策略具有启示意义。
