AUDIT and AUDIT-C: Alcohol Use Screening in Clinical Practice
The Alcohol Use Disorders Identification Test (AUDIT) is the WHO-endorsed gold standard for detecting hazardous and harmful alcohol use. AUDIT score ≥8 = hazardous/harmful use; ≥20 = likely dependence. AUDIT-C ≥3 (women) or ≥4 (men) triggers full AUDIT.
TL;DR: The Alcohol Use Disorders Identification Test (AUDIT) is the WHO-endorsed gold standard for detecting hazardous and harmful alcohol use in primary care and hospital settings. The 3-item AUDIT-C is a validated brief screening alternative. AUDIT score ≥8 = hazardous/harmful use in most guidelines; ≥20 = likely dependence. AUDIT-C ≥3 (women) or ≥4 (men) triggers full AUDIT. Both tools perform best when combined with brief motivational intervention — a conversation clinicians in every specialty can and should be having.
Why Alcohol Screening Matters
Alcohol use disorders affect approximately 283 million people globally and are the third leading preventable cause of death in high-income countries. Despite this, alcohol problems are dramatically underidentified in healthcare settings — surveys consistently show that fewer than 20% of primary care visits include any alcohol screening.
The gap isn't lack of clinician concern. It's lack of routine, validated tools embedded in clinical workflow. The AUDIT was developed precisely to close this gap — a standardized, reproducible screen that any clinician can administer in under 3 minutes, generating a number that guides the clinical response.
AUDIT: Full 10-Item Version
The 10-item AUDIT was developed by the WHO in 1989 and validated across multiple international cohorts. It covers three domains:
Domain 1: Hazardous Alcohol Use (Questions 1–3) Domain 2: Dependence Symptoms (Questions 4–6) Domain 3: Harmful Alcohol Use (Questions 7–10)
Each question is scored 0–4 (question 9 and 10 are scored 0, 2, or 4 only).
| # | Question | Response Options (Score) |
|---|---|---|
| 1 | How often do you have a drink containing alcohol? | Never(0) / Monthly or less(1) / 2–4×/mo(2) / 2–3×/wk(3) / 4+×/wk(4) |
| 2 | How many standard drinks on a typical day when drinking? | 1–2(0) / 3–4(1) / 5–6(2) / 7–9(3) / 10+(4) |
| 3 | How often ≥6 drinks on one occasion? | Never(0) / Less than monthly(1) / Monthly(2) / Weekly(3) / Daily/almost daily(4) |
| 4 | How often unable to stop once started? | Never(0) / Less monthly(1) / Monthly(2) / Weekly(3) / Daily(4) |
| 5 | How often failed to do what was normally expected? | Never(0) / Less monthly(1) / Monthly(2) / Weekly(3) / Daily(4) |
| 6 | How often needed a first drink in the morning? | Never(0) / Less monthly(1) / Monthly(2) / Weekly(3) / Daily(4) |
| 7 | How often felt guilty or remorseful after drinking? | Never(0) / Less monthly(1) / Monthly(2) / Weekly(3) / Daily(4) |
| 8 | How often unable to remember the night before? | Never(0) / Less monthly(1) / Monthly(2) / Weekly(3) / Daily(4) |
| 9 | Have you or others been injured from your drinking? | No(0) / Yes, but not last year(2) / Yes, in last year(4) |
| 10 | Has a relative, friend, doctor expressed concern? | No(0) / Yes, but not last year(2) / Yes, in last year(4) |
Score range: 0–40
AUDIT-C: 3-Item Brief Screener
The AUDIT-C uses only the first three consumption questions of the AUDIT, scored 0–4 each (maximum 12).
| Score | Screening Result |
|---|---|
| Women: ≥3 | Positive — proceed to full AUDIT or brief intervention |
| Men: ≥4 | Positive — proceed to full AUDIT or brief intervention |
| Below threshold | Negative — repeat annually or at next encounter |
Score Interpretation and Clinical Response
| AUDIT Score | Drinking Pattern | Clinical Action |
|---|---|---|
| 0–7 | Low-risk / abstainer | Education; positive reinforcement of safe limits |
| 8–15 | Hazardous use | Brief advice (5–10 min); document and rescreen in 12 months |
| 16–19 | Harmful use / early dependence | Brief motivational counseling + follow-up; consider referral |
| ≥20 | Probable dependence | Referral to specialist addiction services; pharmacotherapy evaluation |
Standard Drink Reference
- Australia: 10 g ethanol
- UK: 8 g ethanol (one "unit")
- USA: 14 g ethanol (one "standard drink")
- WHO: 10 g ethanol
Brief Intervention Framework
FRAMES model (5–10 minutes):
- Feedback
- Responsibility
- Advice
- Menu
- Empathy
- Self-efficacy
USAUDIT: The US-Adapted Version
USAUDIT was developed to recalibrate the consumption questions to US standard drink size and NIAAA low-risk guidelines. The clinical intervention thresholds are equivalent to the original AUDIT (USAUDIT ≥8 = intervention warranted).

Frequently Asked Questions
Q: Should AUDIT be administered by self-report or clinician interview? Both are valid and produce equivalent results.
Q: Can AUDIT be used for monitoring treatment response? Yes. Rescoring at follow-up provides a quantitative measure of change.
Q: What about AUDIT use in pregnancy? AUDIT has lower sensitivity in pregnancy. T-ACE and TWEAK were developed for prenatal screening.
