Demographic and clinical characteristics, including duration of illness and number of hospital admissions, were recorded. In addition, all the participants were assessed using the Alcohol Use Disorder Identification Test in Korea (AUDIT-K), Obsessive Compulsive Drinking Scale in Korea (OCDS-K), and Beck Depression Inventory (BDI) (Table 1). The AUDIT-K is a reliable and valid measurement for assessing AUD severity, including consumption, dependence, and alcohol-related problems in the Korean population (Cronbach's alpha = 0.92), it consists of 10 items, with more than 26 scores being alcohol-dependent (33, 34).
