The AUDIT Score: A Comprehensive Alcohol Screening Tool
The AUDIT (Alcohol Use Disorders Identification Test) is a 10-item questionnaire developed by the World Health Organization to screen for hazardous and harmful alcohol consumption, with scores of 8+ for men up to age 60 or 4+ for women, adolescents, and older men indicating potential alcohol use disorder. 1, 2
Structure and Scoring of AUDIT
The AUDIT questionnaire consists of 10 questions covering three domains:
Alcohol Consumption (Questions 1-3)
- Frequency of drinking
- Typical quantity consumed
- Frequency of heavy drinking episodes
Drinking Behavior/Dependence (Questions 4-6)
- Impaired control over drinking
- Increased importance of drinking
- Morning drinking
Alcohol-Related Problems (Questions 7-10)
- Guilt after drinking
- Blackouts
- Alcohol-related injuries
- Others concerned about drinking
Each question is scored from 0-4 points, with a maximum possible score of 40 points. 1
Interpretation of AUDIT Scores
The interpretation of AUDIT scores follows these thresholds:
- 8+ points for men up to age 60: Indicates hazardous or harmful alcohol consumption 1
- 4+ points for women, adolescents, or men over 60: Indicates hazardous or harmful alcohol consumption 1, 2
More detailed interpretation:
- 0-7: Low-risk drinking or abstinence
- 8-15: Hazardous drinking pattern
- 16-19: Harmful alcohol use
- 20+: Possible alcohol dependence requiring further diagnostic evaluation 1, 3
Clinical Utility
The AUDIT has several advantages over other alcohol screening tools:
High sensitivity and specificity: Among those with hazardous or harmful alcohol use, 92% had an AUDIT score of 8+, while 94% of those with non-hazardous consumption scored below 8 4
Predictive value: AUDIT scores effectively predict:
Cross-cultural validity: Developed through a six-country WHO collaborative project, making it applicable across different cultural contexts 4
AUDIT Variants
AUDIT-C: A shortened version using only the first three consumption questions, useful for rapid screening of risky drinking 1
Single-Question Screening: The NIAAA recommends using question #3 alone ("How often do you have six or more drinks on one occasion?") as an initial screen, followed by the full AUDIT if positive 1
Clinical Application
When a patient screens positive on the AUDIT:
For scores 8-15: Brief intervention focusing on reducing hazardous drinking
For scores 16-19: Brief counseling plus continued monitoring
For scores 20+: Further diagnostic evaluation for alcohol dependence and potential referral for specialized treatment 2, 3
Common Pitfalls
Relying solely on biomarkers: While laboratory tests like GGT and MCV can support diagnosis, the AUDIT is a better predictor of social problems and hypertension than laboratory markers 2, 3
Using inappropriate cut-off scores: Using standard cut-offs without adjusting for gender and age can miss at-risk individuals 1
Failure to follow up on positive screens: A positive AUDIT should prompt further assessment and appropriate intervention 2
The AUDIT provides clinicians with a standardized, validated tool to identify patients at risk for alcohol-related harm before significant health consequences develop, allowing for earlier intervention and potentially preventing progression to more severe alcohol use disorders.
