This 20-item instrument may be given in either a self-report or in a structured interview format; a “yes” or “no” response is requested from each of 20 questions. It is constructed similarly to the earlier Michigan Alcoholism Screening Test (MAST), and the DAST items tend to parallel those of the MAST.
The purpose of the DAST is 1) to provide a brief, simple, practical, but valid method for identifying individuals who are abusing psychoactive drugs; and 2) to yield a quantitative index score of the degree of problems related to drug use and misuse. DAST scores are highly diagnostic with respect to a DSM diagnosis of psychoactive drug dependence.
This assessment will take around 5 minutes.
These questions refer to the past 12 months. Circle your response.
