Predictors of Positive Outcomes for Out-of-Treatment Opiate Injectors Recruited into Methadone Maintenance through Street Outreach

Abstract

This study was conducted to assess behavior change in the areas of drug use, productivity, criminal activity, and HIV risk among street-recruited injection drug users who entered methadone maintenance treatment. In addition, the study examined a number of variables that could account for these changes, including demographics, intervention effects, and treatment-related measures. A total of 168 participants were interviewed at baseline, received outreach interventions, entered methadone maintenance treatment, and were reinterviewed 5–9 months later. Significant (p<.001) improvements were seen in the areas of drug use, productivity, criminality, and HIV risk behaviors. The only variables significantly associated with behavior change were related to drug treatment. In particular, being in treatment at the time of the follow-up assessment had the strongest relationship to positive outcomes, including length of treatment. Having no prior treatment experience was associated with fewer injections at follow-up. These findings emphasize the importance of retaining clients, given the likelihood that positive change is likely to be evidenced while they remain in treatment
