: The objective of this study was to understand substance use patterns of alcohol, marijuana, and simultaneous alcohol and marijuana (SAM) use among 2- and 4-year college students. : Participants were 526 young adults aged 18-23 ( = 355 4-year students; = 171 2-year students) recruited from February 2015 to January 2016 who were participating in a larger longitudinal study. Latent class analysis (LCA) was used to identify past-month classes of alcohol, marijuana, and SAM use. : Among both 2- and 4-year students, a four-class solution yielded the best-fitting model, with 2-year classes tending to include greater marijuana use and less alcohol use and 4-year classes tending to include heavy alcohol use. Demographic characteristics were largely similar across classes. Classes of alcohol, marijuana, and SAM use differed by education status. Screening and prevention efforts for 4-year students may need to be tailored for the needs of 2-year students.
本研究旨在了解 2 年制和 4 年制大学生的酒精、大麻和同时使用酒精和大麻（SAM）的物质使用模式。参与者为 526 名年龄在 18-23 岁之间的年轻人（ = 355 名 4 年制学生； = 171 名 2 年制学生），他们于 2015 年 2 月至 2016 年 1 月参加了一项更大的纵向研究。潜在类别分析（LCA）用于确定过去一个月的酒精、大麻和 SAM 使用类别。在 2 年制和 4 年制学生中，四分类方案得出了最佳拟合模型，2 年制类别的大麻使用量往往较大，酒精使用量较少，而 4 年制类别的酒精使用量往往较大。人口统计学特征在各个类别中基本相似。酒精、大麻和 SAM 使用类别的不同与教育程度有关。针对 4 年制学生的筛查和预防工作可能需要根据 2 年制学生的需求进行调整。
