The CAGE questionnaire is a screening tool used by healthcare professionals to help identify patients with potential alcohol use disorder (AUD). It was developed by Dr. John Ewing, an addiction therapy clinician and psychiatry professor, in 1968 to detect drinking behaviours in patients. The CAGE acronym stands for Cut down, Annoyance by criticism, Guilty feeling, and Eye-openers, which are the four questions that make up the assessment. The questionnaire is designed as a preliminary test to indicate a possible substance abuse problem, and it should not be used for self-diagnosis.

CAGE as a screening tool
The CAGE questionnaire is a widely recognised screening tool used by mental health professionals to assess potential alcohol-related issues. It is a simple and effective tool consisting of four straightforward questions. The questionnaire is designed to quickly reveal whether alcohol consumption is negatively impacting an individual's life. The acronym "CAGE" stands for Cutting down, Annoyance by criticism, Guilty feeling, and Eye-openers, which are the key aspects of the questions. This acronym helps physicians easily recall and apply the questions consistently.
The CAGE questionnaire is not a diagnostic test but rather a preliminary screening tool. It helps highlight possible concerns, and if the responses suggest a potential alcohol problem, further evaluation by a medical professional is necessary for a definitive diagnosis. While it is a valuable tool, it should not be the only means of assessment.
The questionnaire was originally introduced in medical circles before being formally published in The Journal of the American Medical Association (JAMA) in 1984. Following its publication in JAMA, the CAGE questionnaire was widely adopted by psychologists and other mental health experts as an important instrument for identifying alcohol-related concerns.
If an individual is concerned about their alcohol consumption or believes they may be struggling with alcohol addiction, seeking professional help is essential. Various support options are available, including free addiction services offered by the NHS in the UK, although these may have long waiting times. For those in urgent need, private alcohol rehabilitation facilities can provide immediate admission and round-the-clock care in a structured environment.

CAGE questionnaire's four questions
The CAGE questionnaire is a four-question screening tool used by clinicians to help diagnose alcoholism and identify a person's dependency on alcohol. The questions are designed to be less obtrusive than directly asking someone if they have a drinking problem. The four questions are:
Cutting down
Have you ever felt you should cut down on your drinking?
Annoyance by criticism
Have people annoyed you by criticising your drinking?
Guilty feeling
Have you ever felt bad or guilty about your drinking?
Eye-openers
Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover?
Each question can be answered with a simple "yes" or "no". Each "no" answer receives a score of 0, and each "yes" answer receives a score of 1. A score of 2 or 3 indicates a high level of concern for alcohol use disorder, and a score of 4 means the person likely has an alcohol use disorder.
The CAGE questionnaire is not a foolproof test, and it should not be used for self-diagnosis. It is important to seek a diagnosis from a healthcare professional.

CAGE's history and development
The CAGE questionnaire is a widely used screening test for problem drinking and potential alcohol problems. The name CAGE is an acronym formed from the first letter of each of the four questions asked in the questionnaire. The test takes less than a minute to administer and is often used in primary care or other general settings as a quick screening tool.
The CAGE questionnaire is designed to be a self-report survey, with the subject's honesty and accuracy improving if they trust the interviewer or interpreter of the score. The questionnaire does not have a specific intended population and is meant to identify those who drink excessively and need treatment. The test is reliable and valid, but it is not valid for diagnosing other substance use disorders. However, modified versions of the CAGE questionnaire have been implemented for this purpose.

CAGE vs other screening tests
The CAGE questionnaire is a 4-question screening tool used by healthcare practitioners to help discuss a patient’s alcohol use/abuse and determine whether they may have an alcohol use disorder (AUD). The test is not a diagnostic instrument but a screening tool, and does not ask about the quantity, frequency, or pattern of drinking. The questions focus on "Cutting down", "Annoyance by criticism", "Guilty feeling", and "Eye-openers".
The CAGE questionnaire is one of the most efficient and effective screening devices available for alcoholism and is the preferred primary alcohol screening tool by the majority of clinicians. However, other alcohol screening assessments have been developed, including the Michigan Alcohol Screening Test (MAST) and the Alcohol Use Disorders Identification Test (AUDIT). These tests may obtain more thorough information and patient history than CAGE, but many healthcare professionals will administer them after CAGE for patients that require further investigation.
The Michigan Alcohol Screening Test consists of 24 questions that ask about a patient’s drinking behaviour and the adverse consequences they suffer as a result of drinking. The Alcohol Use Disorders Identification Test, on the other hand, is a 10-question test designed to be sensitive to signs of hazardous and harmful drinking as well as alcohol dependence.
Although CAGE is the most popular primary screening tool, it is important to note that it is not a diagnostic test. Regardless of the score, only a licensed professional can make an official diagnosis. If a patient receives a CAGE score of 1 or higher, it is advised that they undergo additional assessment options to determine the next course of action.

Next steps after CAGE
The CAGE questionnaire is a screening tool used to assess alcohol misuse and dependency. It is not a diagnostic instrument, and a score of 1 or higher indicates the need for additional assessment.
Further Assessment
As mentioned, the CAGE questionnaire is a preliminary screening tool. If a patient screens positive for potential alcohol misuse, further assessment is necessary to determine the presence and severity of an alcohol use disorder (AUD). This may involve asking additional questions about the patient's drinking patterns, including the frequency and quantity of alcohol consumption.
Professional Intervention
A score of two or more on the CAGE questionnaire suggests the need for professional intervention. This may involve referral to specialty care, especially for patients with mental health comorbidities or more severe AUD.
Treatment Options
If an AUD is diagnosed, the next step is to develop a treatment plan. Treatment options for alcohol-related challenges include medications and behavioral treatments. Behavioral treatments can include psychotherapy (talk therapy), such as cognitive behavioral therapy (CBT), motivational enhancement therapy, and marital and family counseling. Support groups are also available for individuals struggling with alcohol use.
Routine Screening
The National Institute on Alcohol Abuse and Alcoholism (NIAAA) recommends making alcohol screening a routine part of care. This can help identify individuals with unhealthy alcohol use early on and guide them towards appropriate interventions and treatment options.
Alternative Screening Tools
While the CAGE questionnaire is widely used, other screening tools such as the Michigan Alcohol Screening Test (MAST) and the Alcohol Use Disorders Identification Test (AUDIT) may provide more comprehensive assessments. These tools can be administered after the CAGE questionnaire for patients requiring further evaluation. Additionally, the CAGE-AID questionnaire, a variation of the CAGE questionnaire, includes the use of other drugs in addition to alcohol as part of the assessment.

The CAGE questionnaire is a simple set of four questions that can be answered with a 'yes' or 'no'. It is designed to be administered by a healthcare practitioner to discuss a patient's alcohol use and determine if further assessment is required.
Typically, answering 'yes' to two or more questions suggests a possible alcohol or substance dependency. However, it is important to note that the CAGE questionnaire is not an official diagnosis, which can only be made by a licensed professional.
The CAGE questionnaire is intended for adults who are regular drinkers or substance users. It is recommended that all patients who drink alcohol, regardless of age, should be screened with the CAGE questionnaire.
