临床医生需要与DSM-IV-TR和拟议的DSM-5兼容的大麻特异性诊断筛查。临床样本（n = 174）完成了DSM引导的大麻筛查（DSM-G-CS）21和11个标准版本以及三种药物比较措施。DSM-G-CS描述性统计，信度，三因素分析，和8个ROC和判别分析评价结构效度和实证评分。DSM-G-CS的信度为.88（21项）和.85（11项标准）。采用方差最大旋转的因子分析（FA）得出了六个和三个因子，分别解释了DSM-G-CS 21和11的62%至60%的方差，其中>= 400个负载支持所有项目的保留。大麻戒断子量表信度.952（10个项目）和FA支持一个因素的复合项目。ROC和判别分析支持DSM-G-CS 1.5至2.5的评分截止值作为经验上合理的，基于灵敏度-特异性最大值，准确性概率，置信水平和正确分类的百分比，最佳与Marioblasts筛查量表（MSI）比较。结果支持DSM-G-CS结构效度，经验评分和DSM-IV-TR大麻滥用或依赖的兼容性，并提出DSM-5大麻使用障碍诊断模型。临床上，DSM-G-CS评分为2至3分（或更多）表明可能存在大麻使用障碍，值得评估以确定诊断准确性。(C)2011爱思唯尔有限公司版权所有。
Clinicians need cannabis-specific diagnostic screens compatible with DSM-IV-TR and proposed DSM-5. A clinical sample (n = 174) completed the DSM-Guided-Cannabis Screen (DSM-G-CS) 21 and 11 criteria versions and three drug comparison measures. DSM-G-CS descriptive statistics, reliabilities, three factor analyses, and eight ROC and discriminant analyses evaluated construct validity and empirical scoring. DSM-G-CS reliabilities are .88 (21-items) and .85 (11-criteria). Factor analyses (FA) with varimax rotation derived six and three factors explaining 62% to 60% of variances for the DSM-G-CS 21 and 11 respectively, with >= 400 loadings supporting retention of all items. Cannabis withdrawal subscale reliability .952 (10-items) and FA supported one factor composite item. ROC and discriminant analyses supports DSM-G-CS 1.5 to 2.5 scoring cutoffs as empirically sound, based upon sensitivity-specificity maximums, accuracy probabilities, confidence levels and correctly classified percentages, optimal with Marijuana Screening Inventory (MSI) comparisons. Results support DSM-G-CS construct validity, empirical scoring and compatibility with DSM-IV-TR cannabis abuse or dependence and proposed DSM-5 cannabis use disorder diagnostic models. Clinically, DSM-G-CS scores of two to three (or more) suggest probable cannabis-use disorder, deserving assessment to determine diagnostic accuracy. (C) 2011 Elsevier Ltd. All rights reserved.
