NIDA-CTN-0032

This was a randomized, controlled clinical trial in which 1,281 adults receiving drug abuse treatment were recruited from 12 sites to participate in an HIV testing and counseling study. The purpose of this study was to assess the relative effectiveness of three HIV testing strategies on increasing receipt of test results: (1) on-site HIV rapid testing with brief, participant-tailored prevention counseling, (2) on-site HIV rapid testing with information only, and (3) referral for off-site HIV testing. The study also assessed the effectiveness of the three testing strategies in reducing HIV risk behaviors. Injection drug risk behavior was also assessed.
