What type of instrument is the Alcohol Dependence Scale (ADS)?

The Alcohol Dependence Scale (ADS) is primarily recognized as a diagnostic instrument designed to assess the severity of alcohol dependence. It functions by evaluating various aspects of an individual's relationship with alcohol, including their physical and psychological dependence on it. The scale facilitates the identification of individuals who are experiencing significant issues related to alcohol use, aiding clinicians in making informed decisions regarding treatment and intervention strategies.

While it does require responses from individuals, which might suggest a self-report aspect, its core function is diagnostic rather than purely self-reported. Unlike clinical interviewing tools, which involve direct interaction and qualitative assessment by a clinician, the ADS provides a structured format for quantifying the level of dependence based on standardized criteria. Additionally, it does not serve as a statistical analysis measure, as its purpose is not to conduct statistical evaluations but rather to assess and categorize the severity of an individual's alcohol dependence.
