Alcohol Use Disorders Identification Test (AUDIT)

Abstract

The Alcohol Use Disorders Identification Test (AUDIT) is a highly reliable, 10-item self-report screening questionnaire developed in collaboration with the World Health Organisation (WHO) to measure hazardous and harmful patterns of alcohol consumption. It is specifically designed for routine use in primary care and community health settings for the early detection of individuals at risk. The AUDIT is unique among screening tools as it was developed using a large multinational sample and emphasizes the identification of high-risk consumption rather than solely focusing on long-term dependence. The version presented here includes 12 questions, incorporating two optional items to assess self-perceived drinking problems and difficulty in reducing intake.

Purpose

The primary purpose of the AUDIT is the early detection and identification of individuals whose alcohol consumption levels are classified as hazardous or harmful. By focusing on recent drinking patterns and associated consequences, the instrument serves as an effective tool for clinicians to initiate brief interventions or refer patients for more comprehensive assessment and treatment before severe alcohol use disorders develop.

The scale differs substantially from older screening measures by placing emphasis on the identification of problematic patterns occurring within the recent past (typically the last year), rather than historical or “ever” symptoms of severe dependence. This design makes it particularly useful for preventative health strategies and screening in general healthcare populations.

Construct

The AUDIT is a multidimensional screening tool sensitive to three distinct factors of problematic alcohol use, which collectively constitute the overall construct of alcohol misuse severity:

• Consumption/Hazardous Health Impacts (Questions 1-3): These items quantify the frequency of drinking, the typical amount consumed per occasion, and the frequency of heavy or binge drinking (defined as six or more drinks on one occasion).
• Dependence Symptoms (Questions 4-6): This subscale assesses core criteria related to dependence, including loss of control over drinking, increased need for alcohol (craving or morning drinking), and failure to meet obligations due to drinking.
• Behavioural and Social Problems (Questions 7-10): This factor covers the direct adverse consequences of alcohol use, such as guilt, blackouts, injuries related to drinking, and concerns voiced by others (family or healthcare professionals).

The structured scoring allows for the conceptualization of challenges faced in each of these three categories, which can be presented as standard scores (out of 10) for relative comparison.

Validity

The AUDIT demonstrates strong validity across various indices of problematic drinking. In the initial development sample (Saunders et al., 1993), a critical cut-off value of 8 was established, which showed sensitivities in the mid 0.90s for identifying alcohol-related problems.

Subsequent validation research has provided specific psychometric benchmarks. A key study by Bush et al. (1998) found that among participants interviewed to determine significant alcohol-related problems, a cutoff score of 8 yielded a sensitivity (true positive rate) of 59% and a specificity (true negative rate) of 91%. This indicates that while the AUDIT is highly effective at ruling out problems (high specificity), its moderate sensitivity means that scores should only be used as a strong indication of alcohol problems, necessitating further clinical assessment, and not as a definitive measure to rule out a disorder.

Reliability

The AUDIT is recognized for its strong reliability, particularly its internal consistency, given its development through rigorous statistical rationale and multinational data collection. Research comparing the AUDIT to other established alcohol screening measures, such as the CAGE and Short MAST (Hays & Merz, 1995), confirms its utility and stability in measuring alcohol use patterns. The scale’s focus on symptoms and behaviors occurring within the recent past (the last year) also contributes to its high test-retest reliability in clinical settings where drinking patterns are relatively stable.

Factor Analysis

Factor analytical studies generally support the three-factor structure utilized for clinical interpretation: consumption, dependence, and consequences. This empirical structure validates the scale’s ability to differentiate between individuals who engage in high-risk consumption but are not dependent, and those who exhibit symptoms of alcohol dependence. This multi-factorial approach allows for targeted interventions based on the specific type of alcohol-related problem identified.

Instrument

Test Type: Self-report screening questionnaire.

Format: 12 questions in this version (10 standard AUDIT questions plus 2 optional questions). Total score ranges from 0 to 40.

Language Available: Developed collaboratively by the World Health Organisation, the AUDIT is available and validated in numerous languages globally.

Population Group: General adult population; widely used in primary healthcare and clinical settings.

Age Group: Typically utilized for adults (18 years and older).

Population Details: Originally validated in primary health care patients, but also applied and studied extensively in high-risk groups, such as those enrolled in drink driving treatment programs (Hays & Merz, 1995).

Test Methodology: Can be self-administered, administered via interview, or integrated into electronic health records for routine screening.

Permissions & Fee and Test Year

The AUDIT was developed in 1993 as part of a WHO collaborative project. As a product of the World Health Organisation, the standard 10-item AUDIT is often available in the public domain for non-commercial research and clinical use, facilitating its widespread global adoption. Users are advised to consult official WHO documentation for specific licensing and permissions regarding adaptation or commercial use.

Test Year: 1993.

Items of the Alcohol Use Disorders Identification Test (AUDIT)

IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.

Because alcohol use can affect your health and can interfere with certain medications and treatments, it is important that we ask some questions about your use of alcohol. Please read the following questions and tap the box that best describes your answer to each question.
