ABSTRACT The effectiveness of a bilingual (English/Spanish) computer-assisted alcohol screening/intervention for hazardous and harmful alcohol use, the Health Habits Survey (HHS) was tested in primary care settings. Assessment-only patients were compared with patients exposed to the HHS. Of the 2053 recruited, 151 (7.4%) screened positive on the Alcohol Use Disorders Identification Test (AUDIT) and were re-contacted six months later for follow-up. Significant alcohol reduction was observed in both conditions. No between-group differences were observed. Computer-assisted screening and intervention are feasible in primary care settings and may be a realistic provider-extender when traditional screening is absent or inconsistently implemented.
