Effectiveness of intervention on improvement of drug use among methadone maintained adults.

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.
