The CAGE questionnaire can be used to quickly screen patients for alcohol abuse. It can help identify those patients for whom a more in-depth assessment is warranted.



(1) C: cut down

(2) A: annoyed

(3) G: guilt

(4) E: eye-opener


NOTE: 3 of the 4 questions are shared with T-ACE (C,A,E). Questions are also shared with TWEAK and the 5-shot questionnaires.


total score =

= SUM(points for all 4 questions)



• minimum score: 0

• maximum score: 4

• The higher the score, the greater the likelihood of abusing alcohol.

• Using a cutoff >=2 to define a positive test has a sensitivity of 80% and specificity of 85%.



• Having an "eye opener" strikes me as being pretty specific for alcohol abuse, while the other 3 are not. Feeling bad or guilty might be a better measure of neurosis than actual alcohol misuse.
