Alcohol Use Disorders Identification Test (AUDIT)

The AUDIT is a 10 question self-report screening questionnaire designed to measure harmful alcohol use. It is widely used and useful for routine screening in community health settings and was developed in conjunction with the World Health Organization.

It is sensitive to three factors of problematic alcohol use:

– Hazardous heath impacts
– Dependence symptoms
– Behavioral or social problems of use

The AUDIT differs from other self-report screening tests in that it was based on data collected from a large multinational sample, used a statistical rationale for item selection, emphasizes identification of hazardous drinking rather than long-term dependence and adverse drinking consequences, and focuses primarily on symptoms occurring during the recent past rather than “ever”.

In the test development sample (Saunders et al, 1993), a cut-off value of 8 yielded sensitivities for various indices of problematic drinking that were in the mid 0.90s. Subsequent research has evaluated the AUDIT against other measures of alcohol problems including data from comprehensive interviews. One such study (Bush, et al, 1998) found that among 477 participants who completed the AUDIT and were interviewed to determine significant alcohol related problems, a cutoff score of 8 had a sensitively (false negative) of 59% and a specificity (false positive) of 91%. That is, a score of 8 or more will only be sensitive to 59% of individuals who actually have drinking problems, and one can be 91% sure it is not a false positive. Hays and Merz (1995) gave 832 individuals who were enrolled in drink driving treatment program in California the AUDIT and found that the average score was 8.6 (SD 6.9). This data is used to compute percentiles but given the positive skew should be interpreted with caution.

Total scores range from 0 to 40, with higher scores indicating greater likelihood of hazardous and harmful drinking. Scores are also presented as a percentile compared to a sample of individuals enrolled in a drink driving treatment program (Hays & Merz, 1995). A percentile of 50 indicates a typical score for someone with serious drinking related driving offences, while higher percentiles indicate high severity. Percentiles below 30 likely indicate no drinking problem. Scoring was computed by adding scores (0 – 4) on questions 1 to 8, and questions 9 and 10 scored 0, 2, or 4 points. Total scores of 8 or more are recommended as indicators of hazardous and harmful alcohol use, as well as possible alcohol dependence. However, a score of 8 or more will only be sensitive to 59% of individuals who actually have drinking problems, (Bush et al, 1998). Therefore, scores should only be used as an indication of alcohol problems and not to definitively rule it out.

When looking at individual responses the questions can be conceptualized using the following three categories.
– Likelihood of hazardous heath impacts (questions 1, 2 & 3)
– Dependence symptoms (questions 4, 5 & 6)
– Behavioral or social problems of use (questions 7, 8, 9 & 10)
