Psychometric Properties
| Metric | AUDIT | CAGE |
|---|---|---|
| Sensitivity (AUD detection) | 92% | 71% |
| Specificity | 94% | 90% |
| Hazardous Drinking Detection | Excellent | Poor |
| Severe AUD Detection | Excellent | Good |
| Gender Sensitivity | Good (with adjusted cutoffs) | Poor for women |
When to Use Each Assessment
Primary care alcohol screening
HEDIS-aligned, detects full spectrum including hazardous drinking
Very brief screening with time constraints
Maintains sensitivity with 1-minute administration
Emergency department rapid screening
Ultra-brief; identifies severe cases needing immediate attention
SBIRT implementation
Zone scoring directly guides brief intervention intensity
Detecting at-risk drinking before dependence
Consumption questions identify hazardous use early
Screening in populations with high alcohol use
Better specificity prevents false positives
Key Differences at a Glance
- AUDIT detects hazardous drinking; CAGE only identifies dependence
- AUDIT assesses past-year use; CAGE asks about lifetime patterns
- AUDIT is HEDIS-aligned for quality reporting; CAGE is not
- AUDIT provides zone-based intervention guidance; CAGE is binary
- CAGE is faster (1 minute) but less comprehensive
The Bottom Line
AUDIT is the preferred screening tool for most settings due to its ability to detect the full spectrum of alcohol problems, HEDIS alignment, and zone-based intervention guidance. CAGE is acceptable for rapid severe dependence screening but misses hazardous drinking patterns.
When to Use Both
AUDIT should be the primary screening tool. CAGE may supplement in settings where extreme time constraints exist or when a quick dependence screen is needed before full assessment.
Choosing between them in practice
AUDIT detects the whole spectrum of alcohol problems, from hazardous drinking to dependence, because its first three items ask about consumption. CAGE asks four lifetime consequence questions, so it finds established dependence and misses the at-risk drinker you can still intervene with early. For screening every patient, use AUDIT or its three-item short form AUDIT-C.
Score crosswalk
| Risk zone | AUDIT (0-40) | CAGE (0-4) | Indicated response |
|---|---|---|---|
| Zone I — low risk | 0-7 | 0 | Alcohol education only |
| Zone II — hazardous use | 8-15 | Often still 0-1 | Brief advice (5-10 minutes), re-screen in 3-6 months |
| Zone III — harmful use | 16-19 | 1-2 | Brief counselling plus continued monitoring |
| Zone IV — probable dependence | 20-40 | 2-4 | Referral for diagnostic assessment and treatment |
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
- The gap that matters is Zone II. A patient drinking hazardously usually scores 0 or 1 on CAGE and 8-15 on AUDIT, which is exactly the group brief intervention works best for.
- CAGE asks "ever", so it stays positive for life after a resolved problem. AUDIT asks about the past year, which is what you need for monitoring and for re-screening someone in recovery.
- CAGE performs noticeably worse in women and in younger adults, where consumption-based items carry more of the signal.
- If time is the constraint, use AUDIT-C (the first three AUDIT items, about a minute) rather than dropping to CAGE — you keep the consumption questions and the ability to score a zone.
Evidence notes
- AUDIT was developed by the WHO (Saunders et al., 1993) and is free to use; the manual defines the four risk zones and the response each one calls for.
- AUDIT sensitivity for active alcohol use disorder is around 92% with specificity around 94% at the standard cut-off of 8; CAGE sensitivity at 2+ is roughly 71% and drops sharply for hazardous drinking.
- USPSTF recommends unhealthy-alcohol-use screening in adults with AUDIT-C or the single-item NIAAA question; CAGE is listed as acceptable but not preferred.
Frequently asked questions
CAGE vs AUDIT: which is more accurate?
AUDIT, for nearly every screening purpose. Both find severe dependence, but only AUDIT reliably identifies hazardous and harmful drinking before dependence develops, and only AUDIT gives you a risk zone that tells you what to do next.
CAGE vs AUDIT-C — what is the difference?
AUDIT-C is the first three AUDIT items and asks how often you drink, how much, and how often you have six or more drinks. It takes about the same minute as CAGE but is positive at 4+ for men and 3+ for women and detects hazardous drinking that CAGE misses entirely. AUDIT-C is the better one-minute screen.
What AUDIT score means someone probably has alcohol use disorder?
20 or above (Zone IV) indicates probable dependence and warrants a diagnostic assessment. 8-19 indicates hazardous or harmful drinking that calls for brief intervention rather than referral.
Is CAGE-AID different from CAGE?
Yes. CAGE-AID adapts the same four questions to cover drugs as well as alcohol, and is often used as a prescreen before DAST-10. It has the same lifetime framing and the same blind spot for hazardous use.
Which alcohol screen supports quality reporting?
AUDIT and AUDIT-C are the instruments plans generally accept for unhealthy-alcohol-use screening and SBIRT documentation. CAGE alone typically does not satisfy those measures.
