AUDIT: Alcohol Use Disorders Identification Test

What this assessment is

The Alcohol Use Disorders Identification Test, or AUDIT, is a 10-item screen for risky alcohol use, possible dependence, and alcohol-related harm.

The World Health Organization developed it through a six-country primary care study. The original development paper describes the selection of the 10 questions and the validation of the total score.

The AUDIT is a screen. It does not diagnose an alcohol use disorder.

The AUDIT-C is a shorter three-item form that covers alcohol consumption only. It does not include the AUDIT questions about dependence-related experiences or harm.

Who it was designed for

The AUDIT was designed to identify adults whose alcohol use may place their health at risk. Its first validation took place in primary care settings across different countries and cultures.

It is now used in healthcare, public health, and research. Each setting still needs a clear plan for what happens after a positive result.

Evidence from one population does not automatically transfer to another. Age, sex, culture, local drinking patterns, medical conditions, and the reason for screening can affect how a result should be read.

How it is administered

The standard AUDIT covers the past year. It can be self-completed or asked by an interviewer.

The WHO manual recommends a neutral, nonjudgmental approach and clear confidentiality boundaries. Those conditions matter because people may underreport alcohol use when they expect criticism or consequences.

Use the complete 10-item form. A shortened form, translated version, or changed timeframe needs its own supporting evidence.

What it measures

The AUDIT covers three connected areas:

• alcohol consumption in the first three questions
• experiences associated with possible dependence in the next three
• alcohol-related harm in the final four

The total combines all three areas. Two people can have the same total for different reasons, so the response pattern can be more informative than the number alone.

How scoring works

Most responses score from 0 to 4. The final two questions use 0, 2, or 4 points. The 10 values are added for a total from 0 to 40.

Higher scores indicate greater likelihood of risky use, dependence-related features, or harm.

Do not score a missing response as zero. The WHO manual does not establish one replacement rule for every use. Complete the form when possible, or apply a method that was set before data collection and report it.

How to interpret an AUDIT score

The WHO manual uses four broad zones:

• 0 to 7: Zone I
• 8 to 15: Zone II
• 16 to 19: Zone III
• 20 to 40: Zone IV

A total of 8 or higher is the manual's usual starting point for identifying hazardous or harmful alcohol use and possible dependence. A score of 20 or higher supports further diagnostic evaluation for possible alcohol dependence.

These boundaries are not universal. The manual notes that a cutoff of 7 can improve sensitivity for women and adults over 65, while a cutoff of 10 can improve specificity. It also tells services to consider national and cultural standards.

Do not switch boundaries after seeing the result.

The zones guide the intensity of follow-up. They do not prescribe treatment, prove dependence, or mean that a person below 8 has no alcohol-related risk.

What the score cannot tell you

The AUDIT cannot confirm a diagnosis, measure every consequence of alcohol use, or determine whether withdrawal could be medically dangerous.

It cannot explain a high score by itself. A proper assessment also reviews the pattern and amount of drinking, medications, physical health, mental health, pregnancy, withdrawal history, daily function, and the person's goals.

A low total does not make every drinking pattern safe. Risk can be substantial at lower amounts for some medical conditions, medicines, activities, and stages of life.

Evidence and limitations

The original six-country study found that the AUDIT could identify hazardous and harmful alcohol use across varied primary care settings. That broad development base is a strength.

The score still depends on honest recall and on the exact form used. It can miss risk when drinking is underreported, when the past-year frame hides a recent change, or when a local pattern does not fit the validation sample.

The WHO manual calls its intervention zones tentative. Read the result with the person's circumstances and a defined follow-up process.
