Process / pipelineComprehensive substance use disorder severity assessment
Addiction Severity Index (ASI)
The ASI is a multidimensional, clinician-administered semi-structured interview assessing severity of substance use disorder and related psychosocial problems across seven domains: medical, employment, drug use, alcohol use, legal, family/social, and psychiatric. Developed by McLellan and colleagues in 1980 and refined through editions, it has become the gold standard comprehensive assessment tool in addiction medicine, substance abuse treatment programs, and research. The ASI provides both interview-derived severity ratings (0–9 per domain) and composite scores enabling treatment planning and outcome monitoring.
