AUDIT-C Alcohol Screening
The gold-standard 3-question brief screening for hazardous alcohol use. WHO-validated, 60-second assessment with gender-specific cutoffs.
Why This Health Metric Matters
Why: Early identification of hazardous drinking enables brief intervention and prevents progression to alcohol use disorder.
How: Three questions on frequency, quantity, and binge drinking. Each scored 0-4. Men: positive ≥4, Women: positive ≥3.
- ●86% sensitivity, 89% specificity
- ●Men ≥4, Women ≥3 = positive
- ●Positive screen → full AUDIT recommended
Sample Scenarios
AUDIT-C Questions
Question 1: How often do you have a drink containing alcohol?
Question 2: How many drinks containing alcohol do you have on a typical day when you are drinking?
Question 3: How often do you have 6 or more drinks on one occasion?

What is the AUDIT-C?
The AUDIT-C (Alcohol Use Disorders Identification Test - Consumption) is the gold-standard brief screening tool for hazardous alcohol use. Developed by the World Health Organization, this evidence-based 3-question questionnaire can identify risky drinking patterns in under 60 seconds with remarkable accuracy.
60-Second Screening
Only 3 questions focused on consumption patterns. Quick enough for busy clinical settings.
Clinically Validated
86% sensitivity, 89% specificity. Validated across diverse populations worldwide.
Gender-Optimized
Different cutoffs for men (≥4) and women (≥3) account for biological differences in alcohol metabolism.
AUDIT-C vs Full AUDIT
AUDIT-C (This Tool)
- • 3 questions
- • Focuses on consumption
- • Score range: 0-12
- • Best for initial screening
Full AUDIT
- • 10 questions
- • Includes dependence & harm
- • Score range: 0-40
- • Used after positive AUDIT-C
How Does the AUDIT-C Work?
The Three Questions Explained
Frequency
"How often do you have a drink containing alcohol?"
Assesses regular drinking pattern (0-4 points)
Quantity
"How many drinks do you have on a typical drinking day?"
Measures typical consumption volume (0-4 points)
Binge Frequency
"How often do you have 6 or more drinks on one occasion?"
Identifies high-risk drinking episodes (0-4 points)
Score Calculation
Higher scores indicate greater alcohol consumption and risk
When to Use the AUDIT-C
Primary Care Visits
Routine annual screening. Recommended by USPSTF for all adults.
Emergency Department
Quick screening for alcohol-related injuries and presentations.
Mental Health Settings
Screen for comorbid alcohol use in psychiatric patients.
Pre-Surgical Assessment
Identify use that may affect surgery, anesthesia, or recovery.
Self-Assessment
Personal check on whether your drinking pattern may be risky.
Workplace Wellness
Employee assistance program screening and health initiatives.
AUDIT-C Scoring and Interpretation
Gender-Specific Positive Screen Thresholds
Lower threshold for women reflects biological differences in alcohol metabolism and body water content
Frequently Asked Questions
What does a positive AUDIT-C screen mean?
A positive screen indicates that your drinking pattern may be hazardous to your health and warrants further discussion. It's not a diagnosis of AUD but suggests the need for the full AUDIT assessment and possibly a clinical conversation.
Why are cutoffs different for men and women?
Women have lower body water content (about 52% vs 61%) and less alcohol dehydrogenase enzyme, making them more susceptible to alcohol's effects. The lower cutoff (3 vs 4) accounts for this biological vulnerability.
Should I take the full AUDIT if I screen positive?
Yes. A positive AUDIT-C indicates you should complete the full 10-question AUDIT to assess dependence symptoms and alcohol-related harm. This provides a more complete picture for intervention planning.
How accurate is the AUDIT-C?
The AUDIT-C has excellent accuracy: 86% sensitivity (correctly identifies risky drinkers) and 89% specificity (correctly identifies low-risk drinkers). It's validated across diverse populations and healthcare settings worldwide.
Can I use this for self-assessment?
Absolutely. While designed for clinical use, the AUDIT-C is equally valid for self-assessment. Answer honestly about your drinking over the past year. A positive result suggests discussing your alcohol use with a healthcare provider.
How is AUDIT-C different from CAGE?
AUDIT-C focuses on current consumption patterns, while CAGE asks about lifetime experiences with alcohol. AUDIT-C is better for detecting current hazardous use; CAGE may catch historical alcohol dependence even if currently abstinent.
Clinical Note
The AUDIT-C is a screening tool, not a diagnostic instrument. A positive screen should prompt further assessment and conversation, not automatic diagnosis or judgment.
