While most studies of AIDS risk behavior rely on self-reports, few studies have assessed the reliability of these reports. The present study examines self-reports of drug-related and sexual risk behavior among pairs of injecting drug users (IDUs) recruited from the streets in New York City. Since both members of the pair were interviewed, it was possible to compare their responses in order to assess reliability. Subjects reported on their contacts' demographic data (age, gender, race/ethnicity) and on shared risk behaviors, including syringe sharing. Despite the private and/or illegal nature of AIDS risk behaviors, IDU subjects were generally reliable in their reports of both demographic and AIDS risk behaviors.

OBJECTIVES/OBJECTIVE:To identify factors associated with effective AIDS behavior change among injecting drug users (IDU) in different national settings. DESIGN/METHODS:Cross-sectional surveys of IDU, with determination of HIV status. Trends in city HIV seroprevalence among IDU also used to validate effectiveness of behavior change. SETTING AND PARTICIPANTS/METHODS:Subjects recruited from drug-use treatment programs and outreach efforts in Bangkok, Thailand (n = 601), Glasgow, Scotland (n = 919), New York City, USA (n = 2539), and Rio de Janeiro, Brazil (n = 466). RESULTS:Evidence for the effectiveness of self-reported risk reduction was available for all cities. Univariate followed by multiple logistic regression analyses were used to identify factors associated with self-reported AIDS behavior change. Separate analyses were conducted for each city. Talking about AIDS with drug-using friends was significantly associated with behavior change in all four cities. Talking with sex partners about AIDS, educational level, knowing that someone can be HIV-infected and still look healthy, and having been tested previously for HIV were each significantly associated with behavior change in three of the four cities. CONCLUSIONS:Despite the substantial differences in these national settings, there were common factors associated with effective risk reduction. In particular, risk reduction appears to occur through social processes rather than through individual attitude change. HIV prevention programs need to explicitly incorporate social processes into their work.

One third of all cases of the acquired immunodeficiency syndrome (AIDS) in the United States are associated with the injection of illicit drugs. There is mounting evidence for the effectiveness of syringe exchange programs in reducing human immunodeficiency virus (HIV) risk behavior and HIV transmission among injection drug users. Expansion of syringe exchange would require increased public funding and undoubtedly would include government regulation of syringe exchanges. An analogy is drawn with the present system of regulation of methadone maintenance treatment programs and possible regulation of syringe exchange programs. Specific recommendations are offered to reduce the likelihood of repeating the regulatory problems of methadone maintenance treatment in future regulation of syringe exchange programs.
