A weekly drink count can hide very different patterns. Frequent low-quantity drinking, larger typical amounts, and occasional six-or-more-drink episodes may produce similar totals while raising different questions about medicines, sleep, mood, liver health, injuries, driving, work, relationships, or attempts to cut down.
AUDIT-C is the three-question consumption subset of the World Health Organization Alcohol Use Disorders Identification Test. It asks adults about drinking frequency, typical quantity on drinking days, and the frequency of six-or-more-drink occasions during the past year. Each answer contributes 0 through 4 points, producing a total from 0 to 12.
- Frequency describes how often alcohol was used, not how much was consumed each time.
- Typical quantity captures the usual number of drinks on a drinking day, so glass size and alcohol strength can affect a person's estimate.
- Heavy occasions preserve a high-volume pattern that an average can otherwise conceal.
- Consequences and context remain important at every score because a low total cannot prove that alcohol use is harmless for a particular person.
Programs use different positive-screen references. Scores of 3 or more and 4 or more are common population-dependent lines, while the current VA/DoD implementation uses 5 or more for follow-up and a VA scoring card highlights 8 to 12 as its highest range. These are screening boundaries, not universal definitions of safe drinking or diagnostic thresholds for alcohol use disorder.
AUDIT-C supports a brief conversation or fuller assessment; it cannot diagnose alcohol use disorder, determine its severity, or show whether stopping suddenly is medically safe. If heavy drinking has been prolonged, alcohol withdrawal can be dangerous and a qualified health professional should guide a safe change.
How to Use This Tool:
Answer all three questions for the same past-year period and use a consistent meaning of one drink when estimating quantity.
- Start the AUDIT-C screen and answer the drinking-frequency question for the past year.
- Select the usual number of drinks on a drinking day, then answer how often six or more drinks occurred on one occasion.
- Check the three answers before finishing. The AUDIT-C total is withheld until the response set is complete.
- Compare the total with the 3+, 4+, VA/DoD 5+, and VA card 8+ reference lines, then use Answer review to see whether frequency, quantity, or heavy occasions contributed most.
- Give the item pattern priority over the total when the six-or-more-drinks answer is Daily or almost daily. That response triggers a prompt follow-up notice even though the total remains a screening score.
Interpreting Results:
| Total | Displayed range | Practical reading |
|---|---|---|
| 0 to 2 | Below common references | Below the 3+ and 4+ lines; alcohol-related harm may still need review. |
| 3 | Lower common reference met | Meets the 3+ line but not 4+ or 5+. |
| 4 | Both common references met | Meets the common 3+ and 4+ lines. |
| 5 to 7 | VA/DoD implementation line met | Meets the 5+ implementation line for follow-up. |
| 8 to 12 | Highest VA card range | Supports prompt fuller assessment; it is not a diagnosis or withdrawal assessment. |
Do not use a cutoff as a personal safety boundary. Pregnancy, interacting medicines, medical conditions, prior withdrawal, hazardous situations, or alcohol-related consequences can make follow-up important below a reference line. A high result indicates a stronger screening signal but still requires a fuller history and clinical judgment.
Technical Details:
Each AUDIT-C item uses a literal five-choice map from 0 to 4. Higher codes represent more frequent drinking, a larger typical quantity, or more frequent six-or-more-drink occasions. The score is complete-only, unweighted, and has no reverse-scored items.
Formula Core
The total is the sum of the three keyed item scores.
A ranges from 0 to 12 points. No intermediate rounding is required.
Rule Core
| Item | 0 points | 1 point | 2 points | 3 points | 4 points |
|---|---|---|---|---|---|
| Drinking frequency | Never | Monthly or less | 2 to 4 times per month | 2 to 3 times per week | 4 or more times per week |
| Typical quantity | 0, 1, or 2 drinks | 3 or 4 | 5 or 6 | 7 to 9 | 10 or more |
| Six-or-more occasions | Never | Less than monthly | Monthly | Weekly | Daily or almost daily |
Interpretation first compares the total with exact lower bounds of 3, 4, 5, and 8. Independently, a 4-point response to the six-or-more-drinks item triggers a higher-priority support notice. That item rule does not alter the total or infer withdrawal; it ensures that a frequent heavy-occasion pattern is not hidden by aggregate interpretation.
Responsible Use and Privacy:
Seek qualified medical guidance before abruptly stopping after prolonged heavy drinking, especially with a history of withdrawal symptoms. Alcohol withdrawal can be life-threatening. Emergency symptoms such as seizures, severe confusion, or hallucinations require urgent local medical care.
