How to Calculate AUDIT Alcohol Screening
What is AUDIT Alcohol Screening?
The AUDIT (Alcohol Use Disorders Identification Test) Score Calculator is a 10-item WHO-developed screening tool that identifies hazardous drinking, harmful drinking, and potential alcohol dependence using scores from 0-40.
Formula
AUDIT Score = Sum of 10 items (items 1-8 scored 0-4, items 9-10 scored 0, 2, or 4); Range: 0-40
- TS
- Total AUDIT Score (points (0-40)) — Sum of all 10 AUDIT items indicating drinking risk level
- Qi
- Item Score (points (0-4)) — Individual item response score
- ZN
- Risk Zone (category) — Risk classification: I (low), II (hazardous), III (harmful), IV (dependence)

Common Mistakes to Avoid
- ✕Using the AUDIT to diagnose alcohol use disorder — it is a screening tool that flags risk and prompts further clinical evaluation
- ✕Not using the standard drink definition (14g pure alcohol = 12 oz beer, 5 oz wine, 1.5 oz spirits)
- ✕Applying the same cutoff (8) for all populations — some studies suggest a lower cutoff of 4-5 for women and older adults
Frequently Asked Questions
What AUDIT score means I have a drinking problem?
Scores of 8-15 indicate hazardous drinking that warrants brief intervention. Scores of 16-19 suggest harmful drinking needing extended counseling. Scores of 20+ suggest possible alcohol dependence requiring specialist referral.
What is the AUDIT-C?
The AUDIT-C is an abbreviated 3-question version using only the first 3 consumption items. It is widely used in primary care for quick screening, with cutoffs of 4+ for men and 3+ for women indicating at-risk drinking.
