The CAGE Screening Tool for Substance Use Disorder.

Substance and alcohol use disorder is a serious issue affecting millions worldwide.

The CAGE screening tool that’s used to screen for alcohol-related disorders.

In this article, we will look into the details of the CAGE assessment, understand its questions, scoring system, variations, accuracy, and role in identifying alcohol and substance use disorder.

What is the CAGE Screening Tool?

The CAGE screening tool is simple and effective. Clinicians use it to identify possible signs of alcohol dependency.

The name “CAGE” is derived from the first letter of each of the four questions it comprises:

1. C – Cutting down: Have you ever felt you should reduce your drinking?
2. A – Annoyance by criticism: Have people annoyed you by criticizing your drinking?
3. G – Guilty feeling: Have you ever felt bad or guilty about your drinking?
4. E – Eye-openers: Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover?

These questions are designed to provide insights into someone’s relationship with alcohol and indicate potential issues with alcohol use disorder.

In the early years of substance abuse treatment, clinicians used the tool mainly to assess for alcohol use disorder. However, the tool has been modified since its inception, so it can also be a powerful screening tool for substance use disorder.

Variations of the CAGE Screening Tool

While the CAGE Screening Tool primarily focuses on alcohol use, some variations include questions about drug use. One such variation is the CAGE-AID questionnaire, where AID stands for “Adapted to Include Drugs.”

The CAGE-AID questionnaire includes the same four questions as the CAGE screening tool but expands the scope to encompass alcohol and drug use.

Let’s take a quick look at the CAGE-AID screening tool so it includes drugs other than alcohol:

1. C – Cutting down: Have you ever felt you should reduce your substance use or drinking?
2. A – Annoyance by criticism: Have people annoyed you by criticizing your substance use or drinking?
3. G – Guilty feeling: Have you ever felt bad or guilty about your substance use or drinking?
4. E – Eye-openers: Have you ever used a drug or drink first thing in the morning to steady your nerves or feel normal?

How Should the CAGE Screening Tool be Used?

It’s important to note that the CAGE Screening Tool should not be used as a self-diagnosis tool. Instead, healthcare professionals primarily employ it as an initial screening tool, particularly in primary care settings.

A positive result on the CAGE assessment may prompt further evaluation and diagnostic procedures by a qualified professional.

The CAGE Questionnaire Questions

Drug counselors ask individuals the following four questions to administer the CAGE screening tool.

The response is a simple “yes” or “no” response.

Let’s review the 4 Cage Assessment Questions (rewritten for modern substance use treatment programs):

1. Have you ever felt you should cut down on your substance or alcohol use?
2. Have people annoyed you by criticizing your substance use or drinking?
3. Have you ever felt bad or guilty about your substance use or drinking?
4. Have you ever had to take a drug or a drink first thing in the morning to steady your nerves, get rid of a hangover, or feel normal?

These questions aim to gauge the individual’s perception of their substance use or drinking habits and the potential consequences of their drug or alcohol consumption.

Scoring the CAGE Assessment

Each “yes” response is assigned a score of 1, while each “no” response is a score of 0. The scores for each question are then summed up to provide a total score. A higher total score indicates a higher likelihood of alcohol use severity and/or alcohol or substance use disorder.

A score of 2 or higher is considered clinically significant and may indicate the need for further evaluation, assessment, and intervention.

Interpreting CAGE Results

It’s crucial to remember that the CAGE assessment alone cannot provide a definitive diagnosis of alcohol or substance use disorder. Instead, it serves as an initial screening tool to identify potential signs of alcohol or drug-related issues. If an individual scores 2 or higher on the CAGE assessment, it suggests a need for further evaluation by a qualified professional.

It’s essential to consult a substance use treatment provider who can interpret the results regarding an individual’s overall health, medical history, and lifestyle.

Other tests used to screen for alcohol use disorder.

Other tests commonly used to screen for alcohol use disorder include the

• Michigan Alcohol Screening Test (MAST),
• Alcohol Use Disorders Identification Test (AUDIT), 
• Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) 

Each test has unique questions and scoring systems, providing additional options for healthcare professionals to assess alcohol-related issues comprehensively.

Accuracy of the CAGE Assessment

The CAGE assessment is a relatively accurate tool for identifying potential alcohol or substance use disorder. According to a study published in Occupational Medicine, the CAGE assessment accurately identified people with alcohol or drug dependence issues approximately 93% of the time. This high accuracy rate highlights the effectiveness of the CAGE assessment as a screening tool.

Conclusion

The CAGE assessment is valuable in screening and identifying potential alcohol dependency. While it is not a standalone diagnostic tool, the CAGE screening tool provides drug counseling professionals valuable insights into an individual’s relationship with alcohol or drugs. By asking four simple questions, clinicians can initiate further evaluation and intervention for those requiring assistance with alcohol or drug-related issues.
