Abstract

This study was designed to assess the effect of client characteristics and community interventions on treatment entry and retention, and to evaluate the relative effectiveness of treatment, compared to other interventions, in reducing drug use and crime among out-of-treatment opiate injectors. Subjects (N = 2973) from 15 cities were randomly assigned to: standard intervention (SI)-HIV testing and counseling; or enhanced intervention (EI)-SI plus additional educational sessions stressing responsible drug use. EI in some cities included staff assistance with treatment admission (i.e. ‘active’ referral). All locations provided intervention by community outreach workers. Factors positively associated with treatment entry included: prior treatment, intervention by community workers, assignment to the EI, not injecting cocaine, injecting opiates, and fewer program interventions received. Sites where the EI included active referral achieved significantly higher treatment entry rates than sites where the EI did not. Findings supported the efficacy of treatment over other interventions in reducing drug use and arrests, the addition of staff assistance to facilitate clients' entry into treatment, and the involvement of community outreach workers in achieving treatment entry.
