Nonmonosexual Partnerships: Information, Motivation and Self-Efficacy Among Methamphetamine-Using Men Who Have Sex with Men Who Also Have Sex with Women or Transgender Persons

摘要

Sex with more than one gender is associated with higher substance use and sexual HIV risk. The authors examined knowledge, motivation, and self-efficacy to engage in safer substance use and sexual behavior among methamphetamine-using U.S. men who have sex with more than one gender (N = 343). Almost half (46.2%) of the men reported having sex with a man (MSM) and a woman or transgender partner in the last 30days. Compared to monosexual MSM, nonmonosexual MSM reported greater condom use self-efficacy however, they reported more sexual partners who inject drugs. The authors observed distinct differences between men who do or do not have sex with more than one gender.
