AUDIT and CAGE Tests Explained: How Alcohol Screening Actually Works
Published July 1, 2026 · Updated July 2026 · 8 min read
Two short questionnaires do most of the world's alcohol screening: the CAGE, four questions developed in the 1970s and memorable enough that doctors carry it in their heads, and the AUDIT, a ten-question instrument developed by the World Health Organization that has become the international standard. Both are free, public, validated across decades of research, and takeable in under five minutes. This article walks through each instrument question by question, explains the scoring honestly, including what screening tests can and cannot tell you, and covers what the sensible next step is at each score range.
The CAGE questionnaire: four questions
CAGE is an acronym for its four questions. Have you ever felt you should Cut down on your drinking? Have people Annoyed you by criticizing your drinking? Have you ever felt bad or Guilty about your drinking? Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover (an Eye-opener)? Each yes scores one point. Two or more is the conventional threshold for a clinically significant result warranting fuller assessment, and even a single yes on the eye-opener question is meaningful on its own, since morning drinking to treat withdrawal is a fairly specific marker of physical dependence. CAGE's strengths are speed and its lifetime framing, it surfaces history, not just current habits. Its limitations are equally real: it misses risky drinking that hasn't yet produced guilt or criticism, performs less well in women and older adults, and a motivated person can simply answer no four times. It is a smoke detector, not a diagnosis.
The AUDIT: the ten-question standard
The WHO's Alcohol Use Disorders Identification Test covers three domains. Consumption (questions 1–3): how often you drink, how many drinks on a typical day, and how often you have six or more on one occasion. Dependence signs (4–6): how often in the last year you found you couldn't stop once started, failed to do what was expected because of drinking, or needed a morning drink to get going. Harm (7–10): guilt after drinking, memory blackouts, injuries to yourself or others related to drinking, and whether anyone, relative, friend, doctor, has expressed concern or suggested cutting down. Each question scores 0 to 4, for a maximum of 40. The first three questions alone form the AUDIT-C, a rapid version widely used in primary care, where a score of 4-plus in men or 3-plus in women flags a positive screen.
What the scores mean, zone by zone
AUDIT results are conventionally read in four zones. Zone I, scores 0–7: low-risk drinking; standard advice applies. Zone II, 8–15: risky or hazardous drinking, the enormous middle territory where brief counseling and self-directed change are the evidence-based response, and where interventions work best precisely because dependence hasn't consolidated. Zone III, 16–19: harmful drinking with likely emerging dependence; the recommended response is brief counseling plus continued monitoring, and realistically a conversation with a professional. Zone IV, 20–40: strong indication of alcohol dependence warranting full diagnostic evaluation and, at the heavy-daily-drinking level, a medically informed plan for any reduction, since abrupt cessation can be dangerous for dependent drinkers. Two honesty notes about all screening: scores reflect your candor, minimizing answers produces reassuring nonsense, and a screening score is not a diagnosis. Diagnosis of alcohol use disorder uses DSM-5 criteria applied by a clinician, and it runs on a spectrum, mild, moderate, severe, that a single number can't capture.
Why these ten questions, specifically
The AUDIT's construction explains why it outperforms intuition. Notice what it barely asks about: total volume gets three questions, while seven target the relationship, loss of control, role failure, morning use, guilt, blackouts, harm, and outside concern. Decades of research support that weighting: consequences and control predict trajectory better than quantity, which is why a bottle-of-wine-nightly drinker who has never lost control of an intention can score lower than a weekend drinker who blacks out monthly and keeps promising themselves otherwise. The blackout question deserves special mention because the public radically underrates it: blackouts are not passing out, they are amnesia while awake and acting, caused by rapid blood-alcohol rise shutting down memory formation, and any recurring pattern of them is a significant finding regardless of the rest of the score. The final question, has anyone expressed concern, is quietly the most elegant in the instrument: it outsources detection to the people who see what you can't, and a yes there has been prompting honest reckonings since 1989.
Taking a screen, and what to do with the result
You can self-administer either instrument right now: count your CAGE yeses, or work through the ten AUDIT items honestly, published versions with exact wording are freely available from the WHO, and many health systems offer them online. If you land in the risky zone, the evidence-based responses are refreshingly proportionate: a structured break, defined drinking limits with real counting, the moderation-support approaches covered in our guide to what normal drinking actually looks like, or a handful of counseling sessions. If you land in the harmful or probable-dependence zones, the proportionate response is professional: a primary-care conversation (doctors administer these screens daily and respond with medicine, not judgment), a substance-use evaluation, and, for heavy daily drinkers, medical guidance before any abrupt stop, our safe-withdrawal guide explains why. And whatever the number: a score that surprised you is the screen working. These instruments exist because self-perception calibrates to habit, and ten honest minutes routinely outperform years of private estimating.
Where you'll encounter these screens without asking for them
Knowing where screening happens in the wild is practically useful. Primary care is the big one: annual wellness visits increasingly include AUDIT-C by policy, Medicare pays for annual alcohol screening, and your answers shape what preventive care you're offered, which is an argument for answering accurately rather than reflexively. Emergency departments screen after injuries, falls, and accidents because the alcohol-attributable fraction of trauma is enormous, and a positive ED screen often triggers a brief intervention on the spot, a conversation model called SBIRT with solid evidence behind it. Pre-surgical clearance screens because dependence changes anesthesia planning and because unexpected in-hospital withdrawal is a genuinely dangerous complication. Prenatal care screens universally. Some employers and licensing boards, aviation, medicine, transportation, use these instruments in fitness evaluations, where the stakes and the documentation are different, and where honest legal advice matters more than this article. And courts and treatment programs use the full AUDIT as a baseline and progress measure. In every clinical context, the answers live in your medical record with ordinary confidentiality protections; the screens exist to route care, not to catalog sins, and clinicians are far more alarmed by discovered concealment than by disclosed drinking.
Beyond AUDIT and CAGE: the rest of the screening family
Two instruments dominate, but a few relatives are worth recognizing. The MAST (Michigan Alcoholism Screening Test) is the older, longer lifetime instrument, thorough but dated, still seen in some court settings. The T-ACE and TWEAK adapt screening for pregnancy, where thresholds are lower and tolerance questions do more work. The CRAFFT screens adolescents with age-appropriate questions about cars, friends, and forgetting. The single-question screen, how many times in the past year have you had five or more drinks in a day (four for women), performs surprisingly well in primary care when time allows nothing else, with any answer above zero counting as positive. And the DSM-5 itself, while a diagnostic framework rather than a screen, is publicly readable: eleven criteria covering control, craving, consequences, tolerance, and withdrawal, where two or more within a year defines alcohol use disorder and severity scales with the count. None of this menu changes the practical advice, take the AUDIT honestly and act on the zone you land in, but it demystifies the process: there is no secret test, no gotcha, just a family of well-validated questions that all triangulate the same territory your own uneasy curiosity already found.
