The Drug Abuse Screening Test (DAST-10) is a validated 10-question screening tool used by healthcare professionals worldwide to identify individuals with drug abuse problems. Developed by Harvey Skinner in 1982, it provides a brief, reliable assessment of drug-related issues in the past 12 months. It's used in medical settings, addiction treatment programs, and research to quickly identify those who need further evaluation.
Each question is answered yes or no. Each 'yes' response equals 1 point. Total possible score ranges from 0-10. Score interpretation: 0 = No problems reported, 1-2 = Low level (monitor), 3-5 = Moderate level (further assessment recommended), 6-8 = Substantial level (intensive assessment recommended), 9-10 = Severe level (intensive assessment strongly recommended). Higher scores indicate greater severity.
The DAST-10 is a well-validated, reliable screening tool with good sensitivity and specificity. However, it's a screening instrument, not a diagnostic tool. A positive result indicates the need for comprehensive professional evaluation, not a definitive diagnosis of substance use disorder. It can have false positives or negatives, so clinical judgment and additional assessment are essential for accurate diagnosis.
The DAST-10 covers all non-prescribed drug use including marijuana, cocaine, stimulants, hallucinogens, opioids, inhalants, and prescription medications used non-medically. It does NOT include alcohol (use AUDIT for alcohol screening) or tobacco. The test focuses on patterns of use, consequences, and impact on life rather than specific drug types.
No, the DAST-10 specifically excludes alcohol. For alcohol use screening, use the AUDIT (Alcohol Use Disorders Identification Test) or CAGE questionnaire instead. The DAST-10 instructions explicitly state to consider only drug use, not alcoholic beverages. If you have concerns about both drugs and alcohol, complete both DAST-10 and AUDIT screenings.
If you score 3 or higher (moderate to severe), seek professional help. Contact your primary care physician, a mental health professional, or an addiction specialist for comprehensive evaluation. You can also call SAMHSA's National Helpline (1-800-662-4357) for free, confidential, 24/7 treatment referrals. High scores indicate significant problems that benefit from professional intervention—early treatment improves outcomes.
When you complete the DAST-10 with a healthcare provider, it's protected by medical confidentiality (HIPAA in the US). However, online versions vary—read privacy policies carefully. This calculator doesn't store or transmit your responses. For official screening, complete the test with a licensed healthcare professional who can ensure confidentiality and provide proper follow-up care.
The DAST-10 is typically used as an initial screening tool, during treatment intake, or to monitor progress during recovery. If you're in treatment, your provider may administer it periodically (every 3-6 months) to track changes. For self-assessment, taking it once provides a baseline; retake if your drug use patterns change significantly or if you're concerned about relapse.
