The purpose of the evaluation is to:
The Cannabis Use Identification Test-Revised (CUDIT-R) is a brief cannabis misuse-screening tool, which is widely used to identify cannabis use problems. 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. 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.
