What is the main function of the DIS-IV?

The correct answer highlights that the main function of the DIS-IV (Diagnostic Interview Schedule, Version IV) is to diagnose mental health disorders, including alcohol abuse or dependence. This structured interview tool is designed to align with DSM (Diagnostic and Statistical Manual of Mental Disorders) criteria, making it an essential instrument in clinical settings for accurately identifying specific disorder diagnoses.

It stands out in the context of assessing various psychological conditions by providing a standardized method for clinicians to gauge the presence and severity of alcohol-related issues. By applying this tool, practitioners can systematically determine whether an individual meets the predefined criteria for alcohol abuse or dependence, facilitating accurate diagnosis and subsequent treatment planning.

While other functions like measuring severity of drug use, evaluating psychological well-being, and identifying treatment needs are important in the spectrum of addiction counseling, they are more ancillary roles in the context of the DIS-IV's primary purpose. The focus on diagnosis ensures that individuals receive the appropriate therapeutic intervention based on their specific needs related to alcohol consumption.
