Complete AUDIT-10 alcohol use disorder screening tool. All 10 WHO questions with zone scoring, 3-domain breakdown, AUD severity estimation, and evidence-based intervention guide.
The AUDIT-10 (Alcohol Use Disorders Identification Test) is the gold standard 10-question screening tool developed by the World Health Organization for identifying the full spectrum of unhealthy alcohol use — from hazardous drinking through harmful use to alcohol dependence. It is the most widely validated alcohol screening instrument in the world.
Unlike the abbreviated AUDIT-C (3 questions), the full AUDIT-10 assesses three distinct domains: consumption patterns (questions 1-3), dependence symptoms (questions 4-6), and alcohol-related harm (questions 7-10). This three-domain structure maps closely to the DSM-5 criteria for alcohol use disorder and the ICD-11 classification of alcohol-related conditions.
This calculator scores all 10 AUDIT questions, classifies results into WHO risk zones (I-IV), provides domain-specific breakdowns, estimates AUD severity, and delivers evidence-based intervention recommendations. The four-zone framework guides clinicians from alcohol education (Zone I) through brief intervention (Zone II-III) to specialist referral (Zone IV), following the SBIRT model endorsed by SAMHSA and the USPSTF.
The full AUDIT-10 provides the most complete picture of alcohol use patterns and consequences. Its three-domain structure identifies not just how much you drink, but whether dependence features or harmful consequences have developed, enabling appropriate intervention matching. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.
AUDIT Total = Sum of Q1-Q10 Q1-Q8: scored 0-4 each (max 32) Q9-Q10: scored 0, 2, or 4 each (max 8) Zones: Zone I: 0-7 = Low risk Zone II: 8-15 = Hazardous Zone III: 16-19 = Harmful Zone IV: 20-40 = Possible dependence
Result: Total AUDIT = 10/40 (Zone II). Consumption: 7/12, Dependence: 1/12, Harm: 2/16.
A score of 10 falls in Zone II (Hazardous use), driven primarily by consumption patterns. Brief intervention and counseling are recommended. The low dependence score is encouraging but consumption warrants attention.
The AUDIT was developed in 1989 by Babor et al. for the World Health Organization as the first screening tool designed specifically for international use. Its 10 questions were derived from a 150-item assessment, refined through a 6-country collaborative study. Since then, it has been translated into more than 40 languages and used in over 200 published studies, becoming the most researched alcohol screening instrument globally.
The Consumption domain (Q1-3) captures drinking frequency, typical quantity, and heavy episodic drinking. This domain alone constitutes the AUDIT-C. The Dependence domain (Q4-6) assesses impaired control over drinking, increased salience (morning drinking), and failure to meet obligations — core features of DSM-5 alcohol use disorder. The Harm domain (Q7-10) captures psychological consequences (guilt, blackouts) and social consequences (injuries, others' concern).
The AUDIT's zone framework directly links to the SBIRT intervention model. Zone I patients receive positive reinforcement. Zone II patients receive 5-15 minutes of brief motivational interviewing with explicit drinking goals. Zone III patients receive extended brief counseling with scheduled follow-up. Zone IV patients are referred for comprehensive assessment, which may include medically supervised detoxification and evidence-based pharmacotherapy (naltrexone, acamprosate, or disulfiram) combined with behavioral therapy.
Zone I (0-7): low risk, alcohol education. Zone II (8-15): hazardous use requiring brief advice. Zone III (16-19): harmful use needing brief counseling and monitoring. Zone IV (20-40): possible dependence requiring referral for specialist evaluation and treatment.
AUDIT-C uses only the first 3 questions (consumption). The full AUDIT adds 7 questions assessing dependence symptoms (impaired control, increased salience, morning drinking) and harm (guilt, blackouts, injuries, others' concern). This allows better severity classification and treatment matching.
Yes. Zone II (8-15) reflects hazardous use without necessarily meeting DSM-5 dependence criteria. Heavy episodic drinking can score 8-12 even without any dependence or harm symptoms. The domain breakdown helps distinguish consumption-driven vs dependence-driven scores.
Studies show good reliability and validity when administered in supportive, non-judgmental settings. Underreporting is common (especially in clinical settings with perceived consequences), which is why any positive score should be taken seriously.
SBIRT = Screening, Brief Intervention, and Referral to Treatment. It is the evidence-based framework for responding to AUDIT results: Zone I gets education, Zone II-III gets brief motivational counseling (5-15 minutes), and Zone IV gets referral to addiction medicine.
Yes. The AUDIT has been validated in over 40 languages and in populations worldwide. However, "standard drink" definitions vary by country (10g WHO, 14g US, 8g UK), which affects questions 2-3. This calculator uses the original WHO definitions.
