The CAGE questionnaire is used to test for alcohol abuse and dependence in adults. It is not used to diagnose the disease but only to indicate whether a problem might exist.
The CAGE questionnaire consists of four questions that relate to your use of alcohol:1
If you answer "yes," "sometimes," or "often" to 2 or more of the questions, you might have a problem with alcohol. If you think you or someone you care about has an alcohol use problem, talk with a health professional. Further evaluation by a trained alcohol abuse counselor might be needed.
