目的：大学生大量饮酒及其产生的负面后果代表了美国大学校园的公共卫生问题。罗格斯酒精问题指数（RAPT）是一种常用的测量酒精问题的大学生，但这种措施的心理测量特性从来没有与大学生人口进行全面评估。本研究的目的是进行信度和效度分析，特别是探索性和验证性因素分析，二分法评分版本的措施。方法：数据收集于美国西北地区一所大型公立大学的4，686名本科生和东北部一所大型公立大学的438名学生。结果：探索性因素分析表明，三因素模型提供了最好的拟合数据。这一发现是通过验证性因素分析在两个单独的样本中复制。这三个因素被标记为滥用/依赖症状，个人后果和社会后果。每个因子都表现出足够的内部一致性和收敛效度。结论：本研究的结果表明，一个二分法得分RAPT由三个子因素，是可靠和有效的识别酒精相关的问题，在大学生。
Objective: Heavy college-student alcohol use and its resulting negative consequences represent a public-health problem on American college campuses. The Rutgers Alcohol Problem Index (RAPT) is a commonly used measure of alcohol problems among college students, but the psychometric properties of this measure never have been comprehensively assessed with the college-student population. The purpose of this research was to conduct reliability and validity analyses, particularly exploratory and confirmatory factor analysis, on a dichotomously scored version of the measure. Method: Data were collected on 4,686 undergraduate students at a large, public university in the Northwest region of the United States and 438 students at a large, pub- lic university in the Northeast. Results: Exploratory factor analysis suggested that a three-factor model provided the best fit to the data. This finding was replicated via confirmatory factor analyses in two separate samples. The three factors were labeled Abuse/Dependence Symptoms, Personal Consequences, and Social Consequences. Each individual factor demonstrated adequate internal consistency and convergent validity. Conclusion: The results of this study suggest that a dichotomously scored RAPT consists of three subfactors that are reliable and valid in identifying alcohol-related problems among college students.
