AUDIT-C
Alcohol Use Disorders Identification Test - Consumption · Also known as: AUDIT-C Alcohol Screening, Three-Item Alcohol Screen
The AUDIT-C is a 3-item brief alcohol screening tool derived from the first three questions of the full AUDIT. Published by Bush and colleagues in 2003, it assesses alcohol consumption frequency and quantity in under one minute. The AUDIT-C has become the standard ultra-brief screen for problem drinking in primary care and emergency departments.

When to use it
The AUDIT-C is ideal for universal screening in primary care, emergency departments, hospital inpatient units, and any high-volume clinical setting. It is appropriate for adults of all ages. When a positive AUDIT-C is detected and further evaluation is feasible, administer the full AUDIT to assess dependence and consequences. In resource-constrained settings, AUDIT-C may be the only screening feasible.
Strengths & limitations
- Ultra-brief format (3 items, <1 minute) enables universal screening in busy clinical settings
- Excellent sensitivity (78–86%) and specificity (88–92%) at recommended thresholds for identifying problem drinking
- Strong negative predictive value: negative AUDIT-C reliably rules out significant alcohol problems
- Validated across diverse populations, ages, and healthcare settings
- Simple scoring and interpretation; no complex algorithms required
- Consumption-focused design misses dependent drinkers with low consumption (e.g., daily small amounts, morning drinking)
- Does not assess consequences of drinking; positive screens may overestimate clinical significance
- Dependent on self-report; underestimation is common, especially in clinical settings
- Thresholds vary by sex and age; using single cutoff across populations reduces accuracy
Frequently asked
When should I use AUDIT-C versus full AUDIT?
Use AUDIT-C for rapid universal screening in high-volume settings. A positive AUDIT-C warrants full AUDIT administration to assess dependence and consequences, which AUDIT-C cannot detect. In settings where brief intervention can follow immediately, full AUDIT is preferable at initial screen.
What does an AUDIT-C score of 5 mean for a woman?
A score of 5 exceeds the recommended cutoff of 3 for women, indicating hazardous alcohol consumption. This suggests the woman is drinking at a level associated with future health risks and should receive brief intervention. Scores ≥3 warrant follow-up with full AUDIT to assess dependence symptoms.
Can AUDIT-C miss alcohol dependence?
Yes. AUDIT-C identifies hazardous consumption but cannot detect dependence symptoms (morning drinking, withdrawal, inability to cut down) or consequences. Dependent drinkers who consume moderate amounts may score below the threshold. This is why positive AUDIT-C should be followed by full AUDIT in clinical practice.
Are AUDIT-C cutoffs the same for all ages?
No. Recommended cutoffs vary: ≥4 for men 18–64, ≥3 for women and adults ≥65 years. Age-related differences reflect differences in alcohol metabolism and health vulnerability. Using single cutoff across ages reduces accuracy; apply age-appropriate thresholds.
