DUDIT: Scoring and interpretation

Download page Download PDF

The Drug Use Disorders Identification Test (DUDIT) is an 11-item tool, which can be self or clinician administered, developed as a parallel to the AUDIT to identify problematic past year AOD use [522]. As with the AUDIT, items 1 to 9 are scored on a 0 to 4 scale, with the final two questions scored 0, 2, 4 (Table 70). The maximum score is 44. Scoring guidelines suggest that a score of 6 or more among men, and 2 or more among women, may be indicative of drug-use-related problems. A score of 25 points or more, regardless of sex, is strongly indicative of dependence [522].
