CAGE Alcohol Screening
Four validated questions: Cut down, Annoyed, Guilty, Eye-opener. Score 2+ suggests need for further assessment.
Why This Health Metric Matters
Why: Early identification enables brief intervention and prevents progression.
How: Each Yes = 1 point. Score 2+ suggests clinically significant alcohol problems.
- ●85% sensitivity at cutoff 2
- ●Eye-opener indicates dependence
- ●Used in primary care worldwide

What is the CAGE Questionnaire?
The CAGE questionnaire is one of the most widely used and validated alcohol screening tools in clinical medicine. Developed by Dr. John Ewing at the University of North Carolina in 1968, CAGE is an acronym formed from the key words of its four questions: Cut down, Annoyed, Guilty, and Eye-opener. Its brevity, simplicity, and high accuracy have made it a cornerstone of primary care alcohol screening worldwide.
Quick & Simple
Only 4 yes/no questions that can be answered in under 1 minute, making it ideal for busy clinical settings.
Key Advantages:
- Easy to memorize
- No scoring complexity
- Patient-friendly wording
Clinically Validated
Over 50 years of research supporting its use with 85% sensitivity and 89% specificity at a cutoff of 2+ positive answers.
Performance Stats:
- Sensitivity: 85%
- Specificity: 89%
- PPV: High in medical settings
Lifetime Detection
Particularly effective at identifying lifetime alcohol problems and dependence, not just current hazardous drinking.
Best For Detecting:
- Alcohol dependence
- Lifetime alcohol problems
- Hidden drinking issues
How Does the CAGE Questionnaire Work?
The CAGE questionnaire uses four carefully crafted questions that probe different aspects of problematic alcohol use. Each question targets a specific behavioral or psychological indicator of alcohol use disorder, and the combination provides a comprehensive initial screening.
🔬 The CAGE Questions Explained
Cut down
"Have you ever felt you should Cut down on your drinking?"
Assesses self-awareness of excessive drinking and failed attempts to reduce consumption.
Annoyed
"Have people Annoyed you by criticizing your drinking?"
Explores social consequences and defensiveness about drinking patterns.
Guilty
"Have you ever felt Guilty about your drinking?"
Investigates emotional consequences and internal awareness of problematic behavior.
Eye-opener
"Have you ever had a drink first thing in the morning (Eye-opener) to steady your nerves or get rid of a hangover?"
Most specific indicator of physical dependence and withdrawal symptoms.
When to Use the CAGE Questionnaire
CAGE is designed as a first-line screening tool in various healthcare and personal settings. Its brevity makes it ideal for routine screening where time is limited.
Primary Care Screening
Routine screening during annual physicals, new patient intakes, or health assessments.
Applications:
- Annual health check-ups
- Pre-surgical assessments
- Emergency department triage
Personal Self-Assessment
Private self-evaluation when concerned about your own drinking patterns.
Use When:
- Questioning drinking habits
- Family/friends express concern
- Noticing behavior changes
Occupational Health
Employee assistance programs and workplace health screenings.
Settings:
- EAP assessments
- Safety-sensitive positions
- Return-to-work evaluations
CAGE Scoring and Clinical Interpretation
Scoring is straightforward: each "Yes" answer equals 1 point for a total possible score of 0-4. The clinical cutoff for a positive screen is 2 or more "Yes" responses.
| Score | Result | Interpretation | Recommended Action |
|---|---|---|---|
| 0 | Negative | No alcohol problem indicated | No further action needed |
| 1 | Borderline | Low probability but possible concern | Consider follow-up questions |
| 2 | Positive | Clinically significant; high probability of alcohol problem | Further evaluation recommended |
| 3-4 | Highly Positive | Strong indication of alcohol dependence | Urgent referral for comprehensive assessment |
Special Note: The Eye-opener Question
A positive Eye-opener response alone is highly significant, regardless of other answers. Morning drinking to relieve withdrawal symptoms (shaking hands, anxiety, nausea) indicates physical dependence. If you answer "Yes" to Eye-opener, do NOT stop drinking suddenly without medical supervision due to potentially dangerous withdrawal symptoms.
Frequently Asked Questions
What does a positive CAGE result mean?
A score of 2 or more positive answers indicates clinically significant alcohol problems with about 85% accuracy. It doesn't diagnose alcohol use disorder (AUD) but strongly suggests the need for comprehensive evaluation. About 93% of people scoring 2+ will have some level of alcohol problem.
Why is the Eye-opener question particularly significant?
Morning drinking to relieve withdrawal symptoms (tremors, anxiety, nausea) is a hallmark of physical alcohol dependence. A positive Eye-opener alone warrants serious attention, even if other answers are negative. It may indicate the body has developed tolerance requiring medical support for safe detoxification.
How does CAGE compare to AUDIT?
CAGE (4 questions) is simpler and excels at detecting lifetime alcohol problems and dependence. AUDIT (10 questions) is more sensitive for current hazardous drinking and provides severity grading. CAGE is ideal for quick screening; AUDIT provides more detailed assessment. Using both together gives the most comprehensive picture.
Can CAGE be used for drug screening?
CAGE was specifically validated for alcohol screening. A modified version called CAGE-AID ("Adapted to Include Drugs") adds drug use to each question and can screen for substance use more broadly. For drug-specific screening, the DAST or DUDIT tools are more appropriate.
Is a score of 1 concerning?
A single positive answer is below the clinical cutoff but shouldn't be dismissed entirely. It may warrant follow-up questions about drinking patterns. Context matters: a "Yes" to Eye-opener with a score of 1 is more concerning than "Yes" to Cut down alone. Some clinicians use 1+ as a trigger for more detailed questioning.
Should I answer based on current or past drinking?
The original CAGE asks about lifetime experience ("Have you ever..."). Answer truthfully about any time in your life. CAGE is particularly good at detecting people who have had alcohol problems, even if currently in recovery. This lifetime focus is one of its strengths but may also identify resolved issues.
Clinical Note
CAGE is a screening tool, not a diagnostic instrument. Positive results indicate the need for further evaluation by a healthcare professional, not a definitive diagnosis of alcohol use disorder. Cultural factors, context, and clinical judgment should inform follow-up decisions.
If you score 2 or higher, or answer "Yes" to Eye-opener, please consult with a healthcare provider for proper assessment and guidance.
