本文探讨了精神疾病诊断与统计手册第四版（DSM-IV）的潜在类别结构（采用慕尼黑综合国际诊断访谈进行评估）。其次，以潜在类别结构为经验金标准，运用经典测验理论对大麻滥用筛查测验（CAST）在青少年中的筛查特性进行了评估。样本包括3266名年龄在17至19岁之间的法国大麻使用者。确定了三类潜在的大麻使用者，反映了问题严重程度的连续性：无症状、中度和重度。按性别进行的分析显示，模型拟合最好，尽管在总样本中结果几乎相同。潜伏类是每日大麻使用，每天关节数量和首次实验年龄的良好预测因子。CAST对中度/重度类别显示出良好的筛选特性（受试者工作特征曲线下的面积> 0.85），对重度类别显示出非常好的筛选特性（0.90）。这对男孩更敏感，对女孩更具体。虽然结构上的等效性，跨性别被拒绝，结果表明小性别差异的DSM-IV的潜在结构。CAST在筛选潜在类别结构方面的表现良好，并且上级于经典DSM-IV诊断。版权所有（c）2013约翰威利父子有限公司
This paper explored the latent class structure of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) (assessed with the Munich Composite International Diagnostic Interview). Secondly, the screening properties of the Cannabis Abuse Screening Test (CAST) in adolescents were assessed with classical test theory using the latent class structure as empirical gold standard. The sample comprised 3266 French cannabis users aged 17 to 19 from the general population. Three latent classes of cannabis users were identified reflecting a continuum of problem severity: non-symptomatic, moderate and severe. Gender-specific analyses showed the best model fit, although results were almost identical in the total sample. The latent classes were good predictors of daily cannabis use, number of joints per day and age of first experimentation. The CAST showed good screening properties for the moderate/severe class (area under receiver operating characteristic curve>0.85) and very good for the severe class (0.90). It was more sensitive for boys, more specific for girls. Although structural equivalence across gender was rejected, results suggest small gender differences in the latent structure of the DSM-IV. The performance of the CAST in screening for the latent class structure was good and superior to those obtained with the classical DSM-IV diagnoses. Copyright (c) 2013 John Wiley & Sons, Ltd.
