Although substance use is considered normative in college, continued examination of factors associated with problematic use is merited. This study identified latent substance user classes and examined their relations with sex, race/ethnicity, impulsivity-like facets, and substance use outcomes among 702 undergraduate students. Non-Alcohol Abstaining Users (NAA), Minimal Users (MU), and Polysubstance Users (PSU) emerged from latent class analysis. Variable-centered analyses indicated that substance user classes did not differ by sex. Students in the Asian and Other groups were at greater odds of being in the MU class than either NAA or PSU class, compared to White students. Differential patterns of impulsigenic trait levels emerged across latent classes. The present study highlights the utility of integrating person- and variable-centered approaches in studying heterogeneous substance use behaviors among college students. College PSU are particularly at risk for problematic outcomes, thus warranting preventive intervention that may target impulsigenic traits or polysubstance use.
尽管在大学里，物质使用被认为是正常的，但继续研究与问题性使用相关的因素是值得的。本研究通过对 702 名本科生进行潜在物质使用者类别分析，并考察其与性别、种族/民族、冲动样特质以及物质使用结果之间的关系，确定了潜在的物质使用者类别。非酒精戒断使用者（NAA）、少量使用者（MU）和多物质使用者（PSU）从潜在类别分析中出现。基于变量的分析表明，物质使用者类别在性别上没有差异。与白人学生相比，亚洲学生和其他族裔学生更有可能成为 MU 类别的学生，而不是 NAA 或 PSU 类别的学生。冲动特质水平的差异模式在潜在类别中显现出来。本研究强调了在研究大学生中异质物质使用行为时，整合个体和变量中心方法的效用。大学多物质使用者尤其存在出现问题性结果的风险，因此需要进行预防干预，可能针对冲动特质或多物质使用。
