Taxometric research on substance use problems has yielded inconsistent results, with some studies yielding evidence of a taxonic (categorical) latent structure and other studies yielding dimensional findings. The 2 previous studies that specifically examined cannabis misuse supported a dimensional latent structure. However, given the inconsistent findings for other substance use disorders and the changing legal status of, attitudes about, and patterns of cannabis use, the present study examined the latent structure of cannabis misuse in an attempt to replicate these previous findings. Participants were 804 cannabis using college students who completed measures of cannabis use anonymously online to reduce response biases. Consistent with previous research, the taxometric analyses yielded clear evidence that cannabis misuse has a dimensional latent structure. Furthermore, compared to a dichotomous measure of cannabis misuse, continuous measures of cannabis misuse were significantly more strongly associated with external correlates of cannabis misuse (e.g., stress). These findings have implications for the assessment, treatment, and study of cannabis use disorder. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

大麻滥用的潜在结构：分类法分析。

关于物质使用问题的分类法研究得出的结果不一致，其中一些研究提供了分类（分类）潜在结构的证据，而其他研究则产生了尺寸方面的发现。之前专门研究大麻滥用的2项研究支持了维度潜在结构。但是，鉴于其他药物滥用疾病的发现不一致，以及大麻使用的法律地位，态度和方式的变化，本研究研究了大麻滥用的潜在结构，以试图重复这些先前的发现。参与者是使用大学生的804大麻，他们完成了在线上匿名使用大麻的措施以减少反应偏见。与先前的研究一致，分类法分析提供了明确的证据，证明滥用大麻具有潜在的维度结构。此外，与对大麻滥用的二分措施相比，对大麻滥用的持续措施与大麻滥用（例如压力）的外部相关性明显更强。这些发现对大麻使用障碍的评估，治疗和研究具有重要意义。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
