BACKGROUND Alcohol-induced blackouts are a common high-risk outcome of heavy episodic drinking and are considered a marker of problematic alcohol consumption. One's estimates of the prevalence and peer approval of heavy episodic drinking (i.e., social norm perception, descriptive and injunctive norms, respectively) strongly relate to high-risk alcohol consumption. However, it is unknown whether the intention to blackout and the occurrence of alcohol-induced blackouts also associates with these estimates. Therefore, the purpose of this paper is to explore the relation between participants' social norm perception and alcohol-induced blackout intentions and recent blackout history. METHOD A total of 4430 participants completed an online survey with an average age of 19.97 (SD = 1.70) years. A series of ANOVAs and a structural equation model examined the relation between social norm perception, intention to blackout, and recent blackout history. RESULTS In the structural equation model, the social norm variables (descriptive and injunctive norms) were associated with higher levels of blackout intentions and recent blackout history. The global fit indices suggest that the data fit the model, χ2 (n = 4248, 442) = 7755.90, p < .001, CFI = .96, TLI = .96, RMSEA = .06 (CI90 .061-.064). CONCLUSIONS Participants with a higher likelihood of having a past 30-day history of alcohol-induced blackouts and higher blackout intentions believed that many of their peer groups approved of certain alcohol-related behaviors and that their peer groups drink frequently and drink higher quantities. Future interventions may assess the impact of adjusting social norms on both the intention to blackout and experiencing blackouts.

研究社会规范，酒精引起的停电与大学生停电意图之间的关系。

背景技术酒精引起的停电是大量饮酒的常见高风险结果，并且被认为是有问题的酒精消费的标志。一个人对重度发作性饮酒的患病率和同伴的认可程度（即分别是社会规范感知，描述性和禁令性规范）与高风险饮酒有很大关系。但是，不知道停电的意图和酒精引起的停电的发生是否也与这些估计有关。因此，本文的目的是探讨参与者的社会规范知觉与酒精引起的停电意图和近期停电历史之间的关系。方法共有4430名参与者完成了平均年龄为19.97（SD = 1.70）岁的在线调查。一系列方差分析和结构方程模型研究了社会规范感知，停电意向和近期停电历史之间的关系。结果在结构方程模型中，社会规范变量（描述性和禁令规范）与更高的停电意图和最近的停电历史相关。全局拟合指数表明数据拟合模型，χ2（n = 4248，442）= 7755.90，p <.001，CFI = .96，TLI = .96，RMSEA = .06（CI90 .061-.064） 。结论过去30天有酒精引起的停电史和较高的停电意图的参加者更有可能相信许多同龄人小组认可某些与酒精有关的行为，同龄人经常饮酒并且饮酒量更高。
