Formula: CAGE Score = C + A + G + E (each 0 or 1)
Worked example — CAGE Score: 3/4 (High Risk) - Positive screen requiring follow-up evaluation
Formula
CAGE Score = C + A + G + E (each 0 or 1)
Each of the four CAGE questions is scored 0 (No) or 1 (Yes). The total score ranges from 0 to 4. A score of 2 or more is considered clinically significant, with approximately 93% sensitivity for detecting alcohol problems.
Worked Examples
Example 1: Positive CAGE Screening
Problem:A patient answers Yes to feeling the need to Cut down, Yes to feeling Annoyed by criticism about drinking, No to Guilty feelings, and Yes to needing an Eye-opener.
Solution:CAGE Score = C(1) + A(1) + G(0) + E(1) = 3 Score >= 2: Positive screen Interpretation: Three positive responses strongly suggest alcohol use disorder. Sensitivity at this threshold: ~93% Recommendation: Comprehensive assessment and specialist referral.
Result:CAGE Score: 3/4 (High Risk) - Positive screen requiring follow-up evaluation
Example 2: Negative CAGE Screening
Problem:A patient answers No to Cut down, No to Annoyed, Yes to occasional Guilty feelings about drinking, and No to Eye-opener.
Solution:CAGE Score = C(0) + A(0) + G(1) + E(0) = 1 Score < 2: Below clinical threshold Interpretation: One positive response is below the standard cutoff. Recommendation: May warrant further clinical conversation but does not meet positive screen criteria.
Result:CAGE Score: 1/4 (Low-Moderate Risk) - Below clinical threshold
Frequently Asked Questions
What is the CAGE questionnaire and what does it screen for?
The CAGE questionnaire is a brief, four-question screening tool designed to identify individuals who may have alcohol use problems or alcohol dependence. The acronym CAGE stands for Cut down, Annoyed, Guilty, and Eye-opener, representing the four key questions. Developed by Dr. John Ewing in 1968 and first published in 1984, it has become one of the most widely used screening instruments in clinical medicine due to its simplicity, brevity, and effectiveness. The CAGE questionnaire is not a diagnostic tool but rather a screening instrument that flags individuals who should undergo more comprehensive evaluation. It takes less than one minute to administer and can be incorporated into routine clinical interviews.
How is the CAGE score interpreted and what score indicates a problem?
The CAGE questionnaire is scored by counting the number of yes responses, with each positive answer receiving one point, producing a total score ranging from 0 to 4. A score of 2 or more is considered clinically significant and suggests a high likelihood of alcohol-related problems or alcohol dependence. At a cutoff of 2, the CAGE has a sensitivity of approximately 93 percent and specificity of approximately 76 percent for identifying alcohol problems. A score of 1 may warrant further discussion and clinical observation. However, clinicians should note that CAGE was primarily validated for detecting alcohol dependence rather than hazardous drinking patterns, and it may be less sensitive for detecting early-stage or moderate alcohol problems, particularly in certain populations.
What are the limitations of the CAGE questionnaire in clinical practice?
While the CAGE questionnaire is widely used and clinically valuable, it has several important limitations. First, it was primarily designed to detect alcohol dependence and may miss individuals with hazardous but non-dependent drinking patterns, particularly binge drinkers. Second, the CAGE has shown lower sensitivity in women, younger populations, and certain ethnic groups compared to white male populations where it was originally validated. Third, it does not assess quantity or frequency of drinking, current versus lifetime problems, or the severity of alcohol-related issues. Fourth, patients may underreport or deny symptoms due to stigma. For these reasons, many clinical guidelines now recommend the AUDIT (Alcohol Use Disorders Identification Test) as a more comprehensive primary screening tool.
How does the CAGE questionnaire compare to other alcohol screening tools?
Several validated screening tools exist alongside the CAGE, each with distinct strengths. The AUDIT (Alcohol Use Disorders Identification Test) is a 10-question tool developed by the World Health Organization that assesses both drinking quantity and dependence symptoms, making it more comprehensive. The AUDIT-C is a shortened 3-question version focusing on consumption patterns. The MAST (Michigan Alcohol Screening Test) is a 25-question instrument that provides more detailed assessment. The T-ACE and TWEAK questionnaires were specifically developed for screening pregnant women. Research suggests that AUDIT and AUDIT-C have superior sensitivity for detecting hazardous drinking compared to CAGE, while CAGE performs comparably or better for detecting alcohol dependence specifically.
When should the CAGE questionnaire be administered in a clinical setting?
The CAGE questionnaire should be considered during routine health assessments, annual physical examinations, emergency department visits, psychiatric evaluations, and prenatal care visits. The United States Preventive Services Task Force recommends alcohol screening for all adults aged 18 and older in primary care settings. The CAGE is particularly useful in time-constrained environments such as emergency departments and busy primary care practices because of its brevity. It can be incorporated naturally into clinical conversation without appearing as a formal questionnaire, which may improve patient honesty. However, for comprehensive screening programs, many experts now recommend using the AUDIT-C as the primary screening tool and reserving the CAGE as a supplementary instrument.
