BACKGROUND
Taxometric methods were used to discern the latent structure of cannabis dependence. Such methods help determine if a construct is categorical or dimensional. Taxometric analyses (MAXEIG and MAMBAC) were conducted on data from 1,474 cannabis-using respondents to the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Respondents answered questions assessing DSM-IV criteria for cannabis dependence.
RESULTS
Both taxometric methods provided support for a dimensional structure of cannabis dependence.
CONCLUSION
Although the MAMBAC results were not entirely unequivocal, the majority of evidence favored a dimensional structure of cannabis dependence.
背景
采用分类分析方法来识别大麻依赖的潜在结构。此类方法有助于确定一个构念是类别型还是维度型。对参加2001 - 2002年全国酒精及相关疾病流行病学调查（NESARC）的1474名使用大麻的受访者的数据进行了分类分析（最大特征值法和MAMBAC法）。受访者回答了评估大麻依赖的《精神疾病诊断与统计手册》第四版（DSM - IV）标准的问题。
结果
两种分类分析方法均支持大麻依赖的维度结构。
结论
尽管MAMBAC法的结果并非完全明确，但大多数证据支持大麻依赖的维度结构。
