Severity of Alcohol Dependence Questionnaire (SADQ)

The SADQ is a 20-item self-report instrument that measures the severity of alcohol dependence on a continuum from mild to severe. Developed by Stockwell and colleagues in 1979, it quantifies physical withdrawal symptoms, psychological dependence, and behavioral indicators of dependence to guide treatment intensity and medical management decisions. The SADQ remains a widely used assessment tool in addiction medicine and alcohol treatment settings.
