The purpose of this study is to evaluate the effectiveness of three interventions (individual motivational interviewing, group motivational interviewing, or nurse-led hepatitis health promotion) in reducing drug use. A randomized, controlled trial was conducted with 256 methadone maintained moderate-to-heavy alcohol-using adults attending one of five MM outpatient clinics. Drug use in the overall sample was significantly reduced from baseline to 6-month follow-up, as assessed by a 30-day recall (p 0.0001), with a trend apparent for 6-month recall (p = 0.09). The group and individual programs revealed significant decreases in drug use at the 30-day recall.
