HIV-1 antibody testing among drug users participating in AIDS education

This study aimed to identify factors which predict participation of drug users in HIV-1 antibody testing. The study was part of a randomized controlled trial of three small group AIDS educational programs, in a 21-day in-patient drug detoxification and rehabilitation program. Subjects (n = 497) were clients admitted to the program who consented to participate in the evaluation and who completed baseline data collection. All subjects received pre-test counseling. Testing was offered after 1 week in treatment; 52% decided to be tested. Factors which predicted participation in testing included: no previously reported positive result, a longer stay in treatment, a greater frequency of injection, a greater perceived probability of being infected, and the type of AIDS education. Both actual and perceived level of risk, and the type of AIDS education provided can affect participation in testing programs.
