Student drinking is a major problem on North American campuses and impulsivity is a significant risk factor for heavy drinking. The present study investigates the moderation of the impulsivity-drinking relationship by the expectation that having a drink will lead to positive experiences. Undergraduate drinkers (n=292) completed measures of impulsivity (Barratt Impulsiveness Scale 11; BIS-11), positive drinking expectancies, and alcohol use. Expectancies moderated the relationship between BIS-11 scores and alcohol use. BIS-11 scores were significantly related to typical alcohol quantity, frequency, quantity X frequency, and binge drinking frequency for individuals with average and high levels of positive expectancies, but not for those with few positive expectancies. Implications for interventions targeted at highly impulsive students, using expectancy modification are discussed.
学生饮酒是北美大学校园的一个主要问题，冲动是豪饮的一个重要风险因素。本研究通过预期饮酒会带来积极体验来探讨冲动与饮酒关系的调节作用。本科生饮酒者（n=292）完成了冲动性（巴瑞特冲动量表 11；BIS-11）、积极饮酒预期和酒精使用的测量。预期作用调节了 BIS-11 分数与酒精使用之间的关系。对于具有平均和高水平积极预期的个体，BIS-11 分数与典型酒精量、频率、量 x 频率和狂欢饮酒频率显著相关，但对于那些积极预期较少的个体则不相关。讨论了针对高冲动性学生使用预期修正的干预措施的意义。
