Perceived behavior of others and AIDS risk behavior among heterosexually-identified methamphetamine users.

This study used cross-sectional data to examine perceived risk behavior of social network members as a correlate of AIDS risk behavior in a sample of 230 heterosexually-identified, methamphetamine (meth) users. The highest ratings of risk behavior within participants' social networks were associated with meth use and non-use of condoms. Friends received the highest ratings in terms of overall perceived involvement in drug and sexual risk behaviors. In a multivariate analysis, perceived risk behavior of others, social norms, and attitudes toward AIDS preventive behaviors were significantly associated with intentions to always use condoms. Strategies for addressing negative social influences in the context of sexual risk reduction interventions are described.
