Score the 4-question CAGE alcohol screening questionnaire. Includes interpretation thresholds, SBIRT workflow, and comparison to AUDIT, AUDIT-C, MAST, and other screening tools.
The CAGE questionnaire is one of the most widely used and recognized alcohol screening instruments in clinical medicine. Developed by Dr. John Ewing in 1968, the acronym stands for its four questions: Cut down, Annoyed, Guilty, and Eye-opener. Each question receives a binary yes/no response, with a score of 2 or more considered a positive screen for alcohol use disorder.
The CAGE questionnaire's strength lies in its brevity — it takes less than one minute to administer and can be integrated into routine clinical encounters. With a sensitivity of 71-95% and specificity of 76-95% for detecting alcohol dependence at the ≥2 threshold, it remains a validated first-line screening tool in primary care, emergency departments, surgical pre-assessment, and psychiatric settings.
While CAGE excels at detecting alcohol dependence, it has limitations: it does not quantify current drinking, may miss hazardous (non-dependent) drinking patterns, and is more sensitive for lifetime problems than current use. For comprehensive alcohol assessment, clinicians often follow a positive CAGE screen with the full AUDIT-10 questionnaire or brief intervention using the SBIRT framework.
The CAGE questionnaire provides ultra-rapid alcohol screening in under 1 minute. This calculator includes automated scoring, clinical interpretation, screening tool comparison, and the SBIRT intervention framework — essential for primary care and emergency settings. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.
CAGE Score = Sum of "Yes" answers (0-4) Threshold: ≥2 = Positive screen C = Cut down: "Have you ever felt you should cut down on your drinking?" A = Annoyed: "Have people annoyed you by criticizing your drinking?" G = Guilty: "Have you ever felt bad or guilty about your drinking?" E = Eye-opener: "Have you ever had a drink first thing in the morning?"
Result: CAGE Score: 2/4 — Clinically significant positive screen.
A score of 2 meets the standard positive screening threshold. This patient endorses wanting to cut down and feeling guilty — both items associated with problematic alcohol use patterns. Further assessment with AUDIT-10 and brief intervention are recommended.
Dr. John Ewing developed the CAGE questionnaire at the University of North Carolina in 1968 as a rapid screening tool for alcohol problems in medical settings. Its elegant simplicity — four easily remembered questions that can be seamlessly integrated into clinical conversation — made it one of the first widely adopted substance use screening instruments. Over 50 years later, it remains among the most studied and cited screening tools in addiction medicine.
Despite its enduring popularity, CAGE has known limitations. It was primarily validated for detecting alcohol dependence rather than the broader spectrum of alcohol use disorders. The World Health Organization developed the AUDIT (Alcohol Use Disorders Identification Test) in 1982 specifically to detect hazardous drinking before dependence develops. AUDIT's first three questions (AUDIT-C) provide consumption quantification that CAGE lacks, making AUDIT-C the preferred instrument in many current screening guidelines.
Modern clinical practice integrates CAGE into electronic health record (EHR) templates, nurse intake workflows, and pre-surgical assessments. Some healthcare systems use the single alcohol screening question ("How many times in the past year have you had 5 or more drinks in a day?") as an ultra-rapid pre-screen, reserving CAGE or AUDIT for those who screen positive. The SBIRT framework provides the clinical pathway from screening through intervention and treatment referral.
It depends on the setting. CAGE is faster (1 minute, 4 yes/no questions) and better for detecting alcohol dependence. AUDIT (10 questions) is more comprehensive, detects hazardous drinking before dependence develops, and quantifies current consumption. Many guidelines now prefer AUDIT-C (3 questions) for primary care screening because it catches both hazardous and dependent drinking.
A score of 1 is below the standard positive threshold (≥2) but may warrant clinical attention. Some studies suggest a score of 1 has ~50% sensitivity for alcohol problems. The specific item endorsed matters — a positive Eye-opener is more concerning than a positive Annoyed item.
The original CAGE was designed for alcohol only. However, the CAGE-AID (Adapted to Include Drugs) version adds "or drug use" to each question and screens for both alcohol and drug problems simultaneously. For dedicated drug screening, the DAST-10 is more appropriate.
CAGE has been validated primarily in adult clinical populations. It may have reduced sensitivity in women, young adults, and certain ethnic groups. In pregnant women, the T-ACE or TWEAK questionnaires are preferred. For adolescents, the CRAFFT screening tool is recommended.
SBIRT = Screening, Brief Intervention, and Referral to Treatment. It is an evidence-based public health framework for early identification and intervention for substance use disorders. After screening (CAGE, AUDIT-C), positive results trigger a brief 5-15 minute motivational intervention, with referral to specialized treatment for moderate-to-severe cases.
No. CAGE is a screening tool, not a diagnosis. A positive screen (≥2) indicates increased probability of an alcohol use disorder and the need for further evaluation. Diagnosis of alcohol use disorder requires a comprehensive clinical assessment using DSM-5 criteria (presence of 2+ of 11 diagnostic criteria within 12 months).
