What is the Alcohol Use Disorders Identification Test (AUDIT-C)?

The Alcohol Use Disorders Identification Test Calculated (AUDIT-C) is a brief, 3-question screening tool designed to help identify individuals who are hazardous drinkers or have an active alcohol use disorder. It is a modified version of the full 10-question AUDIT developed by the World Health Organization (WHO). Its brevity and accuracy make it a widely used instrument in primary care settings for early identification of unhealthy alcohol consumption.

This calculator is not a diagnostic tool. Rather, it is a first step to assess if one’s drinking patterns may be risky. A high score suggests that a more in-depth conversation with a healthcare provider is recommended. The test is designed to be a starting point for a conversation about alcohol and health.

AUDIT-C Formula and Scoring Explanation

The AUDIT-C is not a formula in the mathematical sense but a scoring system based on the answers to its three questions. Each answer has a point value from 0 to 4. The total score is the sum of the points from each question, with a maximum possible score of 12.

The interpretation of the score indicates the level of risk associated with your drinking pattern. The thresholds for a “positive screen” (indicating at-risk drinking) are different for men and women.

AUDIT-C Question Variables and Scoring

Variable (Question)	Meaning	Answer Options	Points
Frequency	How often alcohol is consumed.	Never, Monthly or less, 2-4x/month, 2-3x/week, 4+x/week	0-4
Typical Quantity	Number of standard drinks on a typical drinking day.	1-2, 3-4, 5-6, 7-9, 10+	0-4
Binge Frequency	How often six or more drinks are consumed on one occasion.	Never, Less than monthly, Monthly, Weekly, Daily	0-4

Practical Examples of AUDIT-C Scoring

Example 1: Low-Risk Score

A 45-year-old male reports having a drink a few times a month, usually having 1-2 drinks at a time. He never has six or more drinks in one sitting.

• Question 1 (Frequency): “Monthly or less” = 1 point
• Question 2 (Quantity): “1 or 2” = 0 points
• Question 3 (Binge): “Never” = 0 points
• Total Score: 1 + 0 + 0 = 1. This score is below the threshold for a positive screen and suggests low-risk drinking.

Example 2: High-Risk Score

A 30-year-old female reports drinking 2 to 3 times per week. On those days, she typically has 5 or 6 drinks. She has six or more drinks on a weekly basis.

• Question 1 (Frequency): “2 to 3 times a week” = 3 points
• Question 2 (Quantity): “5 or 6” = 2 points
• Question 3 (Binge): “Weekly” = 3 points
• Total Score: 3 + 2 + 3 = 8. For a female, a score of 3 or more is a positive screen. This score of 8 indicates higher-risk drinking, and a follow-up conversation with a doctor is strongly recommended. You may also want to learn about interventions for risky drinking.

How to Use This Alcohol Use Disorders Identification Test Calculator

Using this calculator is simple and completely anonymous. Follow these steps to get your score:

1. Select Your Gender: Choose ‘Male’ or ‘Female’ from the first dropdown. This is important as scoring cutoffs are different for men and women.
2. Answer the Three Questions: For each of the three questions, select the answer from the dropdown menu that best describes your alcohol consumption over the past year.
3. Review Your Results: Your total AUDIT-C score is calculated and displayed instantly. The interpretation below the score will tell you if your drinking pattern is considered low-risk or puts you at increased or higher risk.
4. Reset if Needed: You can press the “Reset” button at any time to clear the form and start over.

Key Factors That Affect Your AUDIT-C Score

Several factors influence your final score. Understanding them is key to interpreting your result from the alcohol use disorders identification test calculated.

• What is a “Standard Drink?”: The test’s accuracy depends on a clear understanding of a standard drink. In the United States, it’s about 14 grams of pure alcohol, which equals a 12-oz beer (5% ABV), a 5-oz glass of wine (12% ABV), or a 1.5-oz shot of 80-proof spirits.
• Frequency of Consumption: How often you drink is a primary factor. Even small amounts, if consumed daily, will result in a higher score than infrequent drinking.
• Quantity Per Occasion: The number of drinks you have on a typical day is a direct measure of consumption volume and a major contributor to your score.
• Binge Drinking: The question about having six or more drinks is a direct measure of binge drinking, a particularly high-risk behavior. This single factor can significantly increase your score.
• Gender: Biological differences mean that alcohol is metabolized differently in men and women. Generally, the threshold for at-risk drinking is lower for women than for men.
• Honesty of Answers: The calculator is only as accurate as the information provided. Honest self-assessment is crucial for a meaningful result. A good resource is the full AUDIT questionnaire from the NIH for a more detailed look.

Frequently Asked Questions (FAQ)

What is a positive AUDIT-C score?

A positive score, which suggests at-risk drinking, is generally defined as a total score of 3 or more for women and 4 or more for men. Some guidelines, like those from the VA, use a cutoff of 5 for everyone.

What is a “standard drink”?

In the U.S., a standard drink contains 0.6 fluid ounces (14 grams) of pure alcohol. This corresponds to 12 oz of regular beer (5% alcohol), 5 oz of wine (12% alcohol), or 1.5 oz of 80-proof distilled spirits (40% alcohol).

Does a positive score mean I have an alcohol use disorder?

No. The AUDIT-C is a screening tool, not a diagnostic test. A positive score indicates that your drinking pattern may be unhealthy and that you could be at risk. It’s a sign that you should talk to a healthcare professional for a full evaluation. See the MDCalc page on the AUDIT-C for more context.

Is this alcohol use disorders identification test confidential?

Yes. This calculator is run in your web browser. No information is stored or sent to a server. Your results are completely anonymous.

What should I do if I have a high score?

A high score indicates that your drinking could be affecting your health. It is strongly recommended to share and discuss your results with a doctor or a qualified healthcare provider. They can provide a full assessment and discuss next steps.

How accurate is the AUDIT-C?

The AUDIT-C is a well-validated screening tool. It is effective at identifying at-risk drinkers and those with active alcohol use disorders across various populations. However, its accuracy relies on honest answers and a correct understanding of what a “standard drink” is.

Why is the binge drinking question “six or more drinks”?

This number is used as a general indicator of high-risk “binge” consumption. Some guidelines refine this, suggesting 4 or more for women and 5 or more for men on a single occasion, but the AUDIT-C traditionally uses a higher threshold for its question.

Can I take this test for someone else?

You can, but the results will only be as accurate as your knowledge of their drinking habits. It is best used as a self-assessment tool. If you are concerned about someone else’s drinking, you should encourage them to speak with a healthcare provider. The UK government provides helpful resources.
