概要	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.	The MAST is a 25-item self-report questionnaire developed to screen for alcohol use disorder and assess alcohol-related problems in adults. First published by Selzer in 1971, it is one of the earliest and most widely used alcohol screening instruments, particularly in primary care, emergency medicine, and addiction medicine settings. The MAST identifies problematic alcohol use through items assessing alcohol consumption patterns, consequences (legal, medical, social, occupational), withdrawal symptoms, and problem recognition. Brief versions (13-item and 10-item) have been developed for rapid screening.
