Alcohol use disorder is identified by which test?
## Core Concept
The question assesses knowledge of screening tools for alcohol use disorder. Alcohol use disorder (AUD) is a medical condition characterized by the inability to stop or control alcohol use despite social, occupational, or health problems. Screening tests are crucial for early identification and intervention.
## Why the Correct Answer is Right
The correct answer, **AUDIT (Alcohol Use Disorders Identification Test)**, is a widely used screening tool developed by the World Health Organization (WHO). It consists of 10 questions that assess an individual's alcohol consumption, drinking behaviors, and experiences. The AUDIT helps identify individuals with hazardous drinking patterns, harmful drinking, and dependent drinking.
## Why Each Wrong Option is Incorrect
* **Option A:** While there are various screening tools for different conditions, without specifying, it's hard to directly refute. However, commonly known tests like the **MADDREPS** or **CAGE questionnaire** are more limited in scope compared to AUDIT.
* **Option B:** This option is too vague without further specification but typically, **blood tests** (like CDT or GGT) are used to assess potential consequences of alcohol use rather than the disorder itself.
* **Option C:** Similarly, **questionnaires** could refer to many tools; however, not all are as comprehensive or specific for alcohol use disorder as AUDIT.
## Clinical Pearl / High-Yield Fact
A key point to remember is that the **AUDIT score ranges from 0 to 40**, with higher scores indicating a greater likelihood of alcohol use disorder. A score of 8 or more generally indicates hazardous or harmful alcohol use. This test is not only useful for screening but also for monitoring changes in alcohol use over time.
## Correct Answer: D. AUDIT.
