Formula
Total AUDIT Score = Sum of Q1 through Q10 (range 0-40)
Each of the 10 AUDIT questions is scored from 0 to 4, with the total score ranging from 0 to 40. The score is divided into four risk zones that guide the appropriate level of intervention, from simple education (Zone I) to specialist referral (Zone IV).
Worked Examples
Example 1: Low-Risk Drinker
Problem: A patient answers: drinks monthly (1), 1-2 drinks (0), never 6+ (0), all remaining questions 0.
Solution: Consumption: 1 + 0 + 0 = 1\nDependence: 0 + 0 + 0 = 0\nHarm: 0 + 0 + 0 + 0 = 0\nTotal = 1\nZone I: Low Risk (0-7)
Result: Score: 1/40 — Zone I (Low Risk) — No intervention needed
Example 2: Hazardous Drinker
Problem: A patient drinks 2-4 times/month (2), 5-6 per occasion (2), weekly binging (3), occasionally can't stop (1), monthly guilt (2), no other issues.
Solution: Consumption: 2 + 2 + 3 = 7\nDependence: 1 + 0 + 0 = 1\nHarm: 2 + 0 + 0 + 0 = 2\nTotal = 10\nZone II: Hazardous (8-15)
Result: Score: 10/40 — Zone II (Hazardous) — Brief advice recommended
Frequently Asked Questions
What is the AUDIT questionnaire?
The AUDIT (Alcohol Use Disorders Identification Test) is a 10-item screening questionnaire developed by the World Health Organization (WHO) in 1982 to identify persons with hazardous and harmful patterns of alcohol consumption. It was designed as a simple, cross-cultural screening instrument for use in primary healthcare settings. The AUDIT has been validated across multiple countries and populations, making it one of the most widely used alcohol screening tools worldwide. It assesses three domains: hazardous alcohol use (questions 1-3), dependence symptoms (questions 4-6), and harmful alcohol use (questions 7-10), providing a comprehensive picture of drinking patterns and consequences.
How is the AUDIT score interpreted?
AUDIT scores range from 0 to 40. Scores are divided into four risk zones: Zone I (0-7) indicates low-risk drinking or abstinence and requires only alcohol education. Zone II (8-15) indicates hazardous drinking and calls for simple advice to reduce drinking. Zone III (16-19) indicates harmful drinking and warrants brief counseling and continued monitoring by a healthcare professional. Zone IV (20-40) suggests possible alcohol dependence and requires referral to a specialist for diagnostic evaluation and potential treatment. A score of 8 or higher in men (or 7 in some guidelines for women) is commonly used as the cutoff for problematic drinking patterns.
What is the difference between AUDIT and AUDIT-C?
The AUDIT-C is an abbreviated version that uses only the first three questions of the full AUDIT, focusing solely on alcohol consumption patterns (frequency of drinking, typical quantity, and frequency of heavy drinking episodes). It scores from 0 to 12 and is commonly used as a quick initial screening in busy clinical settings. A score of 3 or higher for women and 4 or higher for men typically indicates hazardous drinking. The full 10-question AUDIT provides more comprehensive assessment including dependence symptoms and alcohol-related harm, offering better diagnostic specificity and informing appropriate intervention levels. The full AUDIT is recommended when a more thorough evaluation is needed.
Is the AUDIT valid for all populations?
The AUDIT has been validated in numerous countries and across diverse populations, including different age groups, ethnicities, and healthcare settings. It performs well in primary care, emergency departments, psychiatric settings, and criminal justice populations. However, some considerations apply: lower cutoff scores (7 instead of 8) may be more appropriate for women and older adults due to physiological differences in alcohol metabolism. Cultural factors can influence responses, as drinking norms vary significantly worldwide. The AUDIT may be less effective in populations with very low or very high prevalence of alcohol problems, and adolescent-specific modifications have been developed for younger populations.
How often should the AUDIT be administered?
The WHO recommends incorporating AUDIT screening into routine primary healthcare visits, ideally annually. It is particularly important to administer the AUDIT when patients present with conditions commonly associated with alcohol use, such as hypertension, liver disease, depression, anxiety, insomnia, or gastrointestinal problems. Screening should also occur during new patient intake, annual wellness examinations, prenatal visits, and before prescribing medications that interact with alcohol. For patients who previously scored in hazardous or harmful ranges and received brief interventions, follow-up screening at 3-6 month intervals helps monitor progress. Regular screening normalizes the conversation about alcohol use and enables early intervention.
