Cannabis Use Disorder Identification Test (CUDIT)
Abstract: The Cannabis Use Disorders Identification Test-Revised (CUDIT-R) is brief 8-item (c28dr02- c28dr09) measure that identifies individuals with problematic cannabis use within the preceding six months. It assesses consumption, abuse, dependence, and psychological features. The CUDIT-R is a modification of the Alcohol Use Disorders Identification Test (AUDIT; Saunders et al., 1993). The CUDIT-R total score has demonstrated high internal consistency (α = .91; Adamson et al., 2010). In addition to the screener item for CUDIT-R that assesses whether the respondent used cannabis in the last 6 months (c28dr01), our version of this measure includes 3 additional items: one capturing the frequency of use in the past 12 months (c28dr00), another capturing an expanded version an original CUDIT-R item capturing hours stoned in the last 6 months with an option for not using in the past 6 months (c28dr03a), and finally an item capturing number of times the respondent used cannabis in the past 30 days (c28dr10).
