The DSM-5 Level 2—Substance Use—Adult is an adapted version of the NIDA-Modified ASSIST.
The 15-item measure is used to assess the pure domain of prescription medicine, and illicit substance use in adults age 18 and older. It is completed by the individual prior to a visit with the clinician.
If the individual receiving care is of impaired capacity and unable to complete the form (e.g., an individual with dementia), a knowledgeable informant may complete the measure. Each item asks the individual receiving care (or informant) to rate the severity of the individual’s use of various substances during the past 2 weeks.
