CAGE Questionnaire Calculator
A validated 4-question screening tool for identifying potential alcohol problems. Answer each question honestly for an accurate assessment.
What Is the CAGE Questionnaire?
The CAGE questionnaire is a widely used, validated screening tool developed by Dr. John A. Ewing in 1968 and first published in 1984. It consists of four simple yes/no questions designed to identify individuals who may have alcohol problems, including alcohol abuse or dependence.
The name "CAGE" is an acronym formed from the key word in each question: Cut down, Annoyed, Guilty, and Eye-opener. Its brevity makes it one of the most practical screening tools in clinical settings — taking less than one minute to administer.
The CAGE is typically used as an initial screening tool in primary care, emergency departments, prenatal clinics, and psychiatric settings. Unlike laboratory tests, it can identify problem drinking that may not have progressed to the point of causing detectable physiological changes.
The CAGE Acronym Explained
Each letter in CAGE represents a key aspect of problematic alcohol use:
| Letter | Keyword | Question | What It Assesses |
|---|---|---|---|
| C | Cut down | Have you ever felt you should cut down on your drinking? | Self-awareness of excessive drinking |
| A | Annoyed | Have people annoyed you by criticizing your drinking? | Social consequences and external feedback |
| G | Guilty | Have you ever felt bad or guilty about your drinking? | Internal emotional consequences |
| E | Eye-opener | Have you ever had a drink first thing in the morning? | Physical dependence and withdrawal symptoms |
The questions progress from psychological awareness (C, G) to social impact (A) to physical dependence (E). An affirmative answer to the Eye-opener question is particularly concerning, as morning drinking is strongly associated with alcohol dependence.
How to Score the CAGE Questionnaire
Scoring the CAGE questionnaire is straightforward:
Total score range: 0 to 4
Score of 0–1: Negative screen (low probability of alcohol problem)
Score of ≥2: Clinically significant (high probability of alcohol problem)
A score of 2 or more is considered clinically significant and warrants further assessment. Some clinicians use a cutoff of 1 for higher sensitivity, though this reduces specificity. The choice of cutoff depends on the clinical context:
| Cutoff | Sensitivity | Specificity | Best Used When |
|---|---|---|---|
| ≥ 1 | ~96% | ~58% | High-risk populations, prenatal screening |
| ≥ 2 (standard) | ~93% | ~76% | General clinical screening |
| ≥ 3 | ~78% | ~91% | When specificity is prioritized |
Sensitivity and Specificity
The CAGE questionnaire has been extensively validated across diverse populations. At the standard cutoff of ≥ 2:
- Sensitivity for alcohol dependence: 93% (correctly identifies 93 out of 100 people with alcohol dependence)
- Sensitivity for alcohol abuse: 91%
- Specificity: 76% (correctly identifies 76 out of 100 people without alcohol problems)
- Positive predictive value: varies with population prevalence (higher in clinical settings)
These performance characteristics make the CAGE one of the best screening questionnaires for identifying alcohol use disorders, particularly alcohol dependence. It performs best in populations with a high prevalence of alcohol problems, such as medical inpatients and psychiatric patients.
Clinical Applications
The CAGE questionnaire is used in a variety of clinical settings:
Primary Care
Physicians often include CAGE questions during routine health assessments or annual physicals. It can help identify patients whose health complaints may be related to alcohol use, such as hypertension, liver problems, depression, or insomnia.
Emergency Department
CAGE screening in the emergency department is particularly valuable for patients presenting with injuries, falls, or conditions associated with alcohol use. Studies show that up to 30% of trauma patients screen positive.
Prenatal Screening
Identifying alcohol use during pregnancy is critical to prevent fetal alcohol spectrum disorders (FASD). A lower cutoff of ≥ 1 is often used in prenatal settings to maximize sensitivity.
Psychiatric Settings
Alcohol use disorders frequently co-occur with other psychiatric conditions. CAGE screening can help identify comorbid alcohol problems that may complicate treatment.
Limitations of the CAGE
While the CAGE is an excellent screening tool, it has several limitations:
- Lifetime questions: CAGE asks about lifetime experience, not current drinking. A person in long-term recovery may still score positive.
- Reduced sensitivity in certain populations: Less sensitive for women, younger adults, and college students compared to the general population.
- Cultural considerations: Questions about guilt and annoyance may be interpreted differently across cultures.
- Binge drinking: May not detect episodic heavy drinking (binge drinking) as effectively as tools like AUDIT.
- Not a diagnostic tool: A positive screen does not diagnose alcohol use disorder — it indicates the need for further assessment.
- Social desirability bias: Patients may underreport due to stigma, especially when not assured of confidentiality.
CAGE-AID: Adapted to Include Drug Use
The CAGE-AID (CAGE Adapted to Include Drugs) is a modified version that extends the screening to substance use beyond alcohol. Each question is rephrased to include "or drug use":
- Have you ever felt you should cut down on your drinking or drug use?
- Have people annoyed you by criticizing your drinking or drug use?
- Have you ever felt guilty about your drinking or drug use?
- Have you ever had a drink or used drugs first thing in the morning (eye-opener) to steady your nerves or get rid of a hangover?
The CAGE-AID uses the same scoring and interpretation as the standard CAGE. A score of ≥ 2 is considered positive. This version is increasingly used in primary care to screen for a broader range of substance use disorders.
Other Alcohol Screening Tools
Several other validated instruments are available for alcohol screening:
| Tool | Questions | Time | Strengths |
|---|---|---|---|
| AUDIT | 10 | 2–3 min | Detects hazardous drinking and current use; WHO-developed; best for broader screening |
| AUDIT-C | 3 | < 1 min | Consumption-focused; good for current drinking patterns |
| MAST | 25 | 10 min | Highly detailed; best for comprehensive assessment |
| SMAST | 13 | 5 min | Shortened MAST; good compromise of depth and brevity |
| T-ACE | 4 | < 1 min | Designed for prenatal screening; higher sensitivity in pregnant women |
| CAGE | 4 | < 1 min | Fastest to administer; high sensitivity for dependence; ideal for busy settings |
When to Seek Help
If you or someone you know scores 2 or higher on the CAGE questionnaire, consider the following steps:
- Talk to a healthcare provider: Your primary care physician can conduct a comprehensive assessment and discuss treatment options.
- Contact a helpline: The SAMHSA National Helpline (1-800-662-4357) provides free, confidential treatment referrals 24/7.
- Consider counseling: Brief interventions and cognitive-behavioral therapy are effective for alcohol use disorders.
- Explore support groups: Alcoholics Anonymous (AA) and SMART Recovery offer peer support for maintaining sobriety.
- Be honest with yourself: Recognizing a potential problem is the first and most courageous step toward positive change.
Early identification and intervention significantly improve outcomes for alcohol use disorders. The CAGE questionnaire is designed to facilitate this early detection — it is a starting point, not an endpoint.
