CAGE vs AUDIT-C: Which One-Minute Alcohol Screen Should You Use?
CAGE vs AUDIT-C compared: cut-offs, sensitivity, past-year vs lifetime framing, gender-specific thresholds, and which one-minute alcohol screen to use for universal screening.

Psychometric Properties
| Metric | AUDIT-C | CAGE |
|---|---|---|
| Sensitivity (heavy drinking / AUD) | 86% (men, cut-off 4) | 71% (cut-off 2) |
| Specificity | 72-89% | 90% |
| Hazardous drinking detection | Good (consumption items) | Poor |
| Performance in women | Good (cut-off 3) | Reduced sensitivity |
| Performance in young adults | Good | Reduced sensitivity |
When to Use Each Assessment
Universal screening at intake or annual visit
Same one minute, detects hazardous drinking, and gives a defined path into the full AUDIT
Repeating an alcohol screen to track change
Past-year framing means the score can actually improve; CAGE stays positive for life
Screening women or young adults
Gender-specific cut-offs and consumption items preserve sensitivity where CAGE loses it
Quick check for established dependence
High specificity for lifetime dependence when that is the only question being asked
Screening for both alcohol and drugs
CAGE-AID extends the same four questions to drug use as a prescreen
SBIRT documentation for payers
Risk-based result supports the brief intervention decision plans expect to see documented
Key Differences at a Glance
- AUDIT-C measures consumption in the past year; CAGE measures lifetime consequences
- AUDIT-C is positive at 4+ for men and 3+ for women; CAGE is positive at 2+ for everyone
- AUDIT-C detects hazardous drinking before dependence; CAGE largely does not
- AUDIT-C can be repeated to track change; a CAGE score rarely improves
- AUDIT-C escalates naturally to the full 10-item AUDIT and its risk zones
The Bottom Line
AUDIT-C is the better one-minute alcohol screen for almost every setting: it costs the same minute, asks about the past year, uses gender-specific cut-offs, catches hazardous drinking early, and can be repeated to show change. Keep CAGE for the narrow case where you only need a quick, highly specific check for established dependence.
When to Use Both
Screen with AUDIT-C. If it is positive, complete the remaining seven AUDIT items to land in a risk zone. CAGE or CAGE-AID can be added as a prescreen when a program also needs a brief drug-use question, but it should not replace consumption-based screening.
Choosing between them in practice
Both take about a minute. AUDIT-C asks how much and how often someone drinks in the past year and is positive at 4+ for men or 3+ for women; CAGE asks four lifetime consequence questions and is positive at 2+. If you can only ask a handful of questions, AUDIT-C is the better one because it catches hazardous drinking, works in women and younger adults, and can be repeated to track change.
Score crosswalk
| Result | AUDIT-C (0-12) | CAGE (0-4) | What it means |
|---|---|---|---|
| Negative | 0-3 men / 0-2 women | 0 | No current indication; re-screen annually |
| Positive, lower range | 4-6 men / 3-6 women | 1 | Hazardous drinking likely: brief advice, follow the full AUDIT |
| Positive, higher range | 7-9 | 2 | Harmful use likely: brief counselling and monitoring |
| Strongly positive | 10-12 | 3-4 | Probable dependence: diagnostic assessment and referral |
Crosswalks are approximate. Severity bands from different instruments are not interchangeable, so keep one instrument as the measure of record for a given patient.
Switching instruments mid-treatment
- AUDIT-C is a past-year measure, so the same three questions can be repeated at every visit to show whether drinking is changing. CAGE cannot do that — its "ever" framing means the score rarely improves.
- A positive AUDIT-C should be followed by the remaining seven AUDIT items so you land in a defined risk zone before deciding between brief advice and referral.
- Use gender-specific cut-offs. Applying the male threshold of 4 to women loses a meaningful share of true positives.
- In pregnancy and in adolescents, any positive response should be treated as clinically significant regardless of the total.
Evidence notes
- AUDIT-C validation: Bush, Kivlahan, McDonell, Fihn & Bradley (1998), Arch Intern Med 158(16):1789-1795.
- At a cut-off of 4 in men, AUDIT-C sensitivity for heavy drinking or active alcohol use disorder is around 86% with specificity around 72%; at 3 in women, sensitivity is around 73% with higher specificity.
- CAGE at 2+ has sensitivity around 71% for alcohol use disorder and substantially lower sensitivity for hazardous drinking without dependence.
Frequently asked questions
CAGE vs AUDIT-C: which should I use for universal screening?
AUDIT-C. It takes the same amount of time, asks about the past year rather than a lifetime, uses gender-specific cut-offs, and identifies hazardous drinking early enough for brief intervention to help. CAGE mainly identifies people who already meet criteria for a disorder.
What is a positive AUDIT-C score?
4 or more for men and 3 or more for women. Higher scores — 7 and above — point toward harmful use or dependence and should prompt the full 10-item AUDIT.
Can I use AUDIT-C to track change over time?
Yes, and that is a real advantage. Because it asks about the past year and is consumption-based, repeating it at intervals shows whether drinking is actually decreasing. CAGE will not move even when it does.
Does a positive AUDIT-C mean the patient has alcohol use disorder?
No. It means unhealthy drinking is likely and further assessment is indicated. Diagnosis requires a clinical interview against DSM-5 criteria.
