Cannabis is widely used and significant problems are associated with heavier consumption. When a cannabis misuse screening tool, the CUDIT, was originally published it was noted that although it performed well there was concern about individual items.
144 patients enrolled in a clinical trial for concurrent depression and substance misuse were administered an expanded CUDIT, containing the original 10 items and 11 candidate replacement items. All patients were assessed for a current cannabis use disorder with the SCID.
A revised CUDIT-R was developed containing 8 items, two each from the domains of consumption, cannabis problems (abuse), dependence, and psychological features. Although the psychometric adequacy of the original CUDIT was confirmed, the CUDIT-R was shorter and had equivalent or superior psychometric properties. High sensitivity (91%) and specificity (90%) were achieved.
The 8-item CUDIT-R has improved performance over the original scale and appears well suited to the task of screening for problematic cannabis use. It may also have potential as a brief routine outcome measure.
大麻的使用非常广泛,与重度使用相关的问题也很显著。当一种大麻滥用筛查工具,即 CUDIT 最初发表时,人们注意到尽管它表现良好,但人们对个别项目仍有担忧。
144 名参加同时患有抑郁症和物质滥用的临床试验的患者接受了扩展的 CUDIT 测试,其中包含原始的 10 个项目和 11 个候选替换项目。所有患者都使用 SCID 评估当前的大麻使用障碍。
开发了一个包含 8 个项目的修订版 CUDIT-R,每个项目分别来自消费、大麻问题(滥用)、依赖和心理特征领域。尽管原始 CUDIT 的心理测量学充分性得到了确认,但 CUDIT-R 更短,具有同等或更高的心理测量学特性。实现了高灵敏度(91%)和特异性(90%)。
8 项 CUDIT-R 在原始量表的基础上提高了性能,似乎非常适合筛查大麻使用问题。它也可能有潜力作为一种简短的常规结果测量。
