The purpose of this study was to explore whether a brief (3 session) intervention would impact health behavior of veterans with hepatitis C. The main focus of the intervention was on reduction of heavy drinking with patients who have liver disease. Other study goals were to increase the likelihood that patients would seek out substance use treatment and/or hepatitis C health care services. The study also tested the use of a liver function test called CDT/GGT in detecting heavy drinking. The main hypothesis was that a 3 session intervention with personalized feedback about health behavior would result in a reduction in alcohol use and increased use of substance use treatment and hepatology health care.
