The Drug Abuse Screening Test (DAST-10) is a validated 10-item self-report questionnaire that screens for problems related to drug use (excluding alcohol and tobacco) over the past 12 months. It was developed by Harvey Skinner in 1982 as a shorter version of the original 28-item DAST.

How is DAST-10 scored?

Each of 10 yes/no items scores 1 for a problem indicator, except item 3 which is reverse-scored (No=1, Yes=0). Total score range is 0-10. The scoring bands are: 0=no problem, 1-2=low, 3-5=moderate, 6-8=substantial, 9-10=severe.

What does a DAST-10 score of 3-5 mean?

A score of 3-5 indicates moderate drug-related problems. This warrants a brief treatment intervention — typically motivational interviewing, psychoeducation, and a treatment referral discussion. Brief interventions at this level can significantly reduce drug use and prevent progression to severe disorder.

Does DAST-10 screen for alcohol use?

No. DAST-10 explicitly excludes alcohol and tobacco, focusing only on other drugs including illicit substances and prescription medication misuse. Use AUDIT-C or AUDIT for concurrent alcohol screening — both screens are recommended together in primary care.

What is item 3 about and why is it different?

Item 3 asks 'Are you able to stop using drugs when you want to?' — it is reverse-scored because a 'No' response (inability to control use) is the problem indicator. This is the most common DAST-10 scoring error; always verify item 3 scoring direction.

What should I do after a high DAST-10 score (6-10)?

Scores of 6-10 indicate substantial to severe drug-related problems and warrant immediate referral to intensive addiction treatment. This may include intensive outpatient programs (IOP), residential treatment, or medication-assisted treatment (buprenorphine for opioid use disorder, naltrexone for alcohol/opioid).

How accurate is DAST-10 for detecting drug use disorders?

DAST-10 has sensitivity of 70-100% and specificity of 65-80% for drug use disorders, varying by population and threshold used. It performs well across primary care, addiction medicine, and psychiatric settings as validated in multiple studies.

How does DAST-10 differ from CAGE-AID?

CAGE-AID is a 4-item behavioral screen (Cut down, Annoyed, Guilty, Eye-opener) that includes both alcohol and drugs. DAST-10 is a 10-item scale focused exclusively on non-alcohol drugs, providing more detailed severity stratification. Both are recommended in comprehensive substance screening.

Can DAST-10 diagnose substance use disorder?

No. DAST-10 is a screening tool measuring drug-related problem severity, not a diagnostic instrument. DSM-5 substance use disorder diagnosis requires clinical assessment of specific criteria for impaired control, social impairment, and pharmacological effects over 12 months.

Does DAST-10 cover prescription drug misuse?

Yes. DAST-10 covers all drugs other than alcohol and tobacco, explicitly including prescription medications used non-medically (opioids, benzodiazepines, stimulants, sedatives). Patients should be told this when the questionnaire is introduced to ensure prescription drug misuse is reported.

What treatment is available for opioid use disorder identified by DAST-10?

Buprenorphine/naloxone (Suboxone) is first-line pharmacotherapy for opioid use disorder maintenance treatment and is effective in reducing opioid use, overdose mortality, and criminal activity. It can be prescribed in primary care settings by trained physicians. Methadone is available through specialized opioid treatment programs.

Should DAST-10 always be used alongside naloxone education?

For any patient with a positive DAST-10 who uses illicit drugs or misuses opioids, discussion of naloxone availability and administration is strongly recommended. Fentanyl contamination of the drug supply means overdose risk extends even to non-opioid drug users.

DAST-10

DAST-10 is a brief self-report screening tool for problematic use of drugs other than alcohol and tobacco. It helps identify risk level and supports decisions for deeper substance-use assessment.

Formula: DAST-10 total = sum of 10 items (0-10), with item 3 reverse-scored.

Used drugs for non-medical reasons

Abused more than one drug at a time

Able to stop using drugs when you want to

Had blackouts/flashbacks from drug use

Felt bad or guilty about drug use

Family/friends complained about drug involvement

Neglected family due to drug use

Engaged in illegal activities to obtain drugs

Had withdrawal symptoms when stopping drugs

Had medical problems from drug use

How It Works

Patient Completes 10 Yes/No Questions

The patient self-reports on 10 questions about drug use (excluding alcohol and tobacco) in the past 12 months, covering use, loss of control, social/family consequences, illegal activity, withdrawal, and medical problems.

Score with Item 3 Reverse-Coded

Count 'Yes' responses as 1 point each, except for item 3 ('Are you able to stop using drugs when you want to?') where 'No' = 1 point and 'Yes' = 0. Total score ranges 0-10.

Interpret Severity and Act

0 = no problem; 1-2 = low (brief advice); 3-5 = moderate (brief treatment intervention); 6-8 = substantial (intensive outpatient intervention); 9-10 = severe (intensive residential or inpatient treatment referral).

Who Uses the DAST-10

Primary Care Drug Use Screening

Primary Care Physicians

DAST-10 provides validated, structured screening for drug use problems in primary care, enabling risk stratification from brief advice (low score) to specialist referral (high score).

Addiction Medicine Intake Assessment

Addiction Medicine Specialists

At addiction medicine intake, DAST-10 quantifies drug use problem severity across multiple domains, informing treatment intensity decisions and complementing clinical interviews.

Pain Management Clinic Monitoring

Pain Management Physicians

In patients prescribed opioids or other controlled substances, DAST-10 monitors for emerging drug use problems over time, supporting safe prescribing and early intervention when scores rise.

Pre-Surgical Drug Use Assessment

Surgeons & Anesthesiologists

Identifying drug use disorders before surgery allows planning for opioid management, withdrawal prevention, and anesthesia considerations in patients with active substance use problems.

Employee Assistance Program Screening

Occupational Health & HR

Employee assistance programs (EAPs) use DAST-10 to identify employees with drug use problems and match intervention intensity to score severity, from brief counseling to formal treatment referral.

Pro Tips

Item 3 Is Reverse-Scored — Don't Forget

Item 3 ('Are you able to stop using drugs when you want to?') is the only reverse-scored item. A 'No' response = 1 point; 'Yes' = 0. This is the most common scoring error with DAST-10 — always check item 3 direction before calculating total.

DAST-10 Explicitly Excludes Alcohol and Tobacco

DAST-10 was designed for drug use assessment excluding alcohol and tobacco. Always use AUDIT or AUDIT-C for alcohol screening concurrently. Inform patients clearly: 'These questions are about drugs other than alcohol and tobacco.'

Fentanyl-Contaminated Supply Dramatically Raises Overdose Risk

Any positive DAST-10 in patients who use illicit drugs should prompt discussion of fentanyl contamination risk and naloxone availability. Fentanyl is now detected in many non-opioid drug supplies, making naloxone relevant for stimulant and other drug users.

Brief MI for Moderate Scores Before Referral

For DAST-10 scores of 3-5 (moderate), brief motivational interviewing (MI) exploring ambivalence and readiness to change often improves engagement with more intensive treatment. Direct referral without motivational support frequently fails at this stage.

Buprenorphine Is First-Line for Opioid Use Disorder

For patients whose DAST-10 positive result involves opioid use, buprenorphine/naloxone (Suboxone) is first-line pharmacotherapy for opioid use disorder maintenance treatment and can be initiated in primary care settings by waiver-trained physicians.

Stimulant, Cannabis, and Opioid Use Disorders Have Different Treatments

DAST-10 identifies drug use problems but not specific substances. Treatment differs substantially: opioids → buprenorphine/methadone; stimulants → contingency management, CBT; cannabis → CBT, motivational enhancement therapy. Substance-specific follow-up is essential.

Validate Positive Screens with Toxicology and History

A positive DAST-10 should be confirmed with comprehensive substance history (drug, frequency, route, quantity, last use) and urine toxicology screening. Self-report may underestimate use, especially for stigmatized substances.

Prescription Drug Misuse Counts as Drug Use

DAST-10 covers misuse of prescription medications (opioids, benzodiazepines, stimulants) as well as illicit drugs. Explicitly ask about prescription drug misuse when introducing DAST-10, as patients may not self-identify this as 'drug use.'

DAST-10 Has Been Validated Across Multiple Settings

DAST-10 has been validated in primary care, addiction medicine, emergency medicine, and psychiatric populations with reasonable sensitivity (70-100%) and specificity (65-80%). Performance varies by population, so clinical judgment should always complement the score.

Common Questions About Your Results

Evidence-Based Methodology

DAST-10 developed by Skinner (Addict Behav 1982). Sensitivity 70-100%, specificity 65-80% for drug use disorders depending on population and threshold. Validated in primary care, addiction medicine, and psychiatric settings. SAMHSA recommends DAST-10 as part of SBIRT. NIDA QuickPic test also available for rapid single-item screening. Skinner (1982) original 28-item DAST was shortened to 10 items without significant loss of discriminative ability.
