Rapid HIV Testing and Counseling in Drug Abuse Treatment

This is a randomized controlled clinical trial in which adults receiving drug abuse treatment will be recruited to participate in a multi-center HIV testing and counseling study. The purpose of this study is 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 will also assess the effectiveness of the three testing strategies in reducing HIV risk behaviors.
