Sexual aggression (SA) is a significant public health problem, with the majority of SA involving alcohol. The present study examined associations between alcohol expectancies for sexual enhancement, event-level alcohol use, and the likelihood of SA perpetration. Young, adult non-problem drinking men participated in a laboratory session and completed a background survey that included measures of alcohol expectancies. Subsequently, men completed 6-week and 3-month follow-up surveys in which they reported their sexual experiences each day during the intervening 6-week period using Timeline Followback procedures. The analytic sample consisted of the 421 men (age = 24.66, = 2.69) who reported having sex at least once during the follow-up period. Multilevel models showed a significant alcohol expectancies X alcohol use interaction at the between-person level: Controlling for time and alcohol expectancies for aggression, stronger alcohol expectancies for sexual enhancement were associated with greater SA perpetration likelihood among men who consumed high amounts of alcohol before sexual encounters but not among men who consumed low amounts. Alcohol prevention programs should consider addressing men's alcohol expectancies for sexual enhancement to reduce risk for SA perpetration.
性侵犯（SA）是一个重大的公共卫生问题，大多数性侵犯都与酒精有关。本研究考察了对性增强的酒精预期、事件层面的酒精使用与实施性侵犯可能性之间的关联。年轻的成年无问题饮酒男性参加了一次实验室环节，并完成了一项背景调查，其中包括对酒精预期的测量。随后，男性完成了为期6周和3个月的随访调查，他们在随访期间使用时间线回溯程序报告了每天的性经历。分析样本包括421名男性（年龄 = 24.66，标准差 = 2.69），他们报告在随访期间至少有过一次性行为。多层次模型显示，在个体层面上，酒精预期与酒精使用之间存在显著的交互作用：在控制时间和对攻击行为的酒精预期后，对性增强的酒精预期越强，在性接触前大量饮酒的男性实施性侵犯的可能性就越大，但在少量饮酒的男性中并非如此。酒精预防项目应考虑解决男性对性增强的酒精预期问题，以降低实施性侵犯的风险。
