Primary care validation of a single-question alcohol screening test

Area of Science:

• Primary Care Medicine
• Addiction Science
• Public Health Screening

Background:

• Unhealthy alcohol use is common but frequently undiagnosed in primary care.
• Early identification is crucial for timely intervention and improved patient outcomes.

Purpose of the Study:

• To validate the National Institute on Alcohol Abuse and Alcoholism (NIAAA)-recommended single-item screening tool for unhealthy alcohol use within primary care settings.
• To assess the accuracy of this brief screen in identifying at-risk individuals.

Main Methods:

• A cross-sectional study involving adult primary care patients.
• Participants completed a single screening question about daily alcohol consumption (defined by specific drink counts for men and women).
• Unhealthy alcohol use was confirmed via standardized diagnostic interviews and validated 30-day calendar methods.

Main Results:

• The single-item screen demonstrated 81.8% sensitivity and 79.3% specificity for detecting unhealthy alcohol use.
• Screening accuracy remained consistent across various demographic groups.
• Performance was comparable to existing multi-item screening tools.

Conclusions:

• The NIAAA-recommended single screening question is an accurate and efficient tool for identifying unhealthy alcohol use in primary care.
• These findings support the routine implementation of this brief screen in clinical practice.
