AUDIT-C vs CAGE: Which Alcohol Self-Screen Is More Accurate?
AUDIT-C and CAGE are the two most-used alcohol screening questionnaires. Here's how they differ, which is more sensitive, and when each is best.
AUDIT-C (Alcohol Use Disorders Identification Test - Consumption) is a 3-question WHO-derived screen — more sensitive (~85-95%) for hazardous drinking. CAGE is a 4-question dependence-focused screen from 1974 — faster but less sensitive. AUDIT-C is the modern preferred first-line screen; CAGE remains useful for quick confirmation in primary care.
The two screens
AUDIT-C (1998, Bush et al.)
Three questions, scored 0-4 each (max 12):
- How often do you have a drink containing alcohol?
- How many drinks on a typical day when you drink?
- How often do you have 6+ drinks on one occasion?
Positive threshold: ≥4 for men, ≥3 for women. AUDIT-C is the consumption module of the full 10-question AUDIT (WHO, 1989).
CAGE (1974, Ewing)
Four yes/no questions:
- Have you ever felt you should Cut down on your drinking?
- Have people Annoyed you by criticizing your drinking?
- Have you ever felt bad or Guilty about your drinking?
- Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover (Eye-opener)?
Positive threshold: ≥2 yes answers suggests possible alcohol use disorder.
Side-by-side
| Feature | AUDIT-C | CAGE |
|---|---|---|
| Year introduced | 1998 | 1974 |
| Source | WHO AUDIT subset | John Ewing |
| Number of questions | 3 | 4 |
| Time to complete | ~60 seconds | ~30 seconds |
| Detects hazardous drinking | Excellent (sens. ~85-95%) | Moderate (sens. ~75-85%) |
| Detects dependence | Good | Excellent (designed for this) |
| Sex-specific thresholds | Yes (M ≥4, F ≥3) | No |
| Captures binge drinking | Yes (Q3) | No directly |
| Best for | General screening | Quick confirmation |
When AUDIT-C is the better choice
- You want to detect hazardous drinking, not just dependence (catches earlier-stage problems)
- You want sex-specific accuracy (CAGE doesn't differentiate)
- You want to capture binge-drinking patterns (AUDIT-C Q3)
- Modern primary care + occupational health prefer AUDIT-C
When CAGE is still useful
- Very brief screen needed (30 seconds)
- Suspect alcohol dependence specifically (not just hazardous use)
- Patient may resist a "drinking test" but accept simple yes/no questions
- Clinical setting where dependence-confirmation is the focus
What both miss
- Lifestyle impact (sleep, mood, work, relationships affected by drinking)
- Trajectory (is it getting worse, stable, or improving?)
- Co-occurring conditions (depression, anxiety, trauma — common with drinking)
- Severity gradation (both are screens, not diagnostic)
The Should I Quit Drinking? tool combines AUDIT-C with lifestyle-impact questions to give a fuller decision frame. Free, browser-only.
If you score positive
A positive AUDIT-C or CAGE doesn't diagnose alcohol use disorder — it suggests follow-up is warranted. Steps:
- See a GP for full assessment (full 10-question AUDIT, plus DSM-5 AUD criteria check)
- Consider 30-day no-alcohol trial as low-risk experiment
- If you've been drinking heavily daily: do NOT quit cold turkey — risk of seizures. Get medical guidance first.
- Free resources: SMART Recovery, AA, online programs (Sunnyside, Reframe, Tempest)
- Therapy (motivational interviewing, CBT for AUD) has strong RCT evidence
The bottom line
AUDIT-C is the modern preferred first-line screen for hazardous drinking. CAGE remains useful as a quick dependence-focused supplement. Neither replaces a clinician assessment — both are gateways to one. If either screens positive, take it seriously. If you're scoring 8+ on AUDIT-C, see a GP this week, not next year.

Frequently asked
Which is more sensitive?
AUDIT-C has higher sensitivity (~85-95% for hazardous drinking) compared to CAGE (~75-85%). AUDIT-C also detects hazardous-but-not-yet-dependent drinking better. CAGE was designed primarily for dependence detection.
How long does each take?
AUDIT-C: 3 questions, ~1 minute. CAGE: 4 questions, ~30 seconds. Both are designed for primary care + self-administration.
What scores are concerning?
AUDIT-C: ≥4 (men) or ≥3 (women) suggests hazardous drinking. CAGE: ≥2 of 4 questions = positive screen for likely alcohol use disorder. Either positive screen warrants follow-up with a clinician.
Should I take both?
Usually one is enough. AUDIT-C is more comprehensive for general screening. CAGE is faster for confirming whether dependence may be present. Many clinicians use AUDIT-C first, then CAGE or full AUDIT for positive screens.
