DAST Questionnaire

The Drug Abuse Screening Test, or DAST, is composed of 28 questions about prior drug use (including prescription). This test takes about 10 minutes to administer and score. The DAST is used when assessing problems and consequences related to drug misuse in adults and adolescents in a primary care, psychiatric clinics, or impatient facilities.


  • Very high internal consistency and reliability on full version (Skinner, 1982)
  • Validated for use on adolescent populations (Martino et al, 2000)
  • Effective for diagnosis of lifetime alcohol abuse or dependence (Bohn et al., 1991)


  • The DAST is a self-administered test designed to provide a brief screening for drug abuse, followed by further assessment by a health care professional if necessary.


  • Several versions available including versions specific to adolescents
  • Consistent with DSM-III drug criteria, with good discriminant and concurrent validity (Gavin et. Al, 2006).


  • Not significantly validated in pain patients
  • Does not predict aberrant drug behavior during pain treatment (Passik, et al., 2008)
  • Specific for help-seeking populations, but less validated for other groups (Skinner, 1982).
  • As a primarily self-administered assessment, populations not seeking treatment for drug-related problems may under-report drug abuse symptoms
