酒精引起的停电描述了酒精消费导致的记忆丧失。大约一半的大学生报告说，他们一生中经历过停电。停电与负面后果的风险增加有关，包括严重伤害。研究记录了两种类型的停电，整体（EB）和片段（FB）。然而，研究是有限的，缺乏一个有效的措施，区分这两种形式的停电。本研究采用混合方法来改善年轻人中FB和EB的评估。我们特别寻求改进现有的酒精诱导的停电措施（ABOM），这是从一个相对较小的项目池，不区分FB和EB。研究1采用三轮认知访谈与大学生（N=31），以完善现有的评估项目。研究2保留了19个精确的黑障项目。研究2采用表面效度、因素分析、项目反应理论和外部效度分析，在大量饮酒的大学生（N=474）中检验了两因素的停电模型，并开发和验证了一种新的停电措施（ABOM-2）。迭代因子分析表明，这些项目是由相关的EB和FB因素，符合我们的假设。外部验证分析证明了收敛和判别效度，并且有初步证据表明这两个因素具有差异预测效度（例如，FB与强化饮酒动机相关，而EB与应对和从众动机相关）。酒精诱导的停电措施-2（ABOM-2）提高测量停电的经验，在大学生，并将有助于检查EB和FB作为酒精相关的结果在未来的研究中的差异预测。
Alcohol-induced blackouts describe memory loss resulting from alcohol consumption. Approximately half of college students report experiencing a blackout in their lifetime. Blackouts are associated with an increased risk for negative consequences, including serious injury. Research has documented two types of blackouts, en bloc (EB) and fragmentary (FB). However, research is limited by lack of a validated measure that differentiates between these two forms of blackout. This study used a mixed methods approach to improve the assessment of FB and EB among young adults. We specifically sought to improve the existing Alcohol-Induced Blackout Measure (ABOM), which was derived from a relatively small pool of items that did not distinguish FB from EB. Study 1 used three rounds of cognitive interviewing with college students (N=31) to refine existing assessment items. Nineteen refined blackout items were retained for Study 2. Study 2 used face validity, factor analysis, item response theory, and external validation analyses to test the two-factor blackout model among heavy-drinking college students (N=474) and to develop and validate a new blackout measure (ABOM-2). Iterative factor analyses demonstrated that the items were well-represented by correlated EB and FB factors, consistent with our hypothesis. External validation analyses demonstrated convergent and discriminant validity, and there was preliminary evidence for the two factors having differential predictive validity (e.g., FB correlated with enhancement drinking motives, while EB correlated with coping and conformity motives). The Alcohol-Induced Blackout Measure-2 (ABOM-2) improves measurement of blackout experiences among college students and will facilitate examination of EB and FB as differential predictors of alcohol-related outcomes in future studies.
