Interpretation of the results and thresholds

  • This instrument’s 10 items are ranked on a dichotomous scale. The maximum total score is 10.
  • A threshold of 3 or 4 is recommended to screen a drug use problem. The threshold appears to come close to most criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM). A score of 9 or more indicates a severe problem.

Is the questionnaire available in the toolkit?


Other versions

The 28-item first version is derived from the Michigan Alcoholism Screening Test (MAST). A shorter 20-item version was then created, followed by the 10-item version.
