title: The role of sexual arousal and sexual partner characteristics in HIV+ MSM's intentions to engage in unprotected sexual intercourse.
abstract: OBJECTIVE
  This study investigated the effects of sexual arousal and sexual partner characteristics as determinants of HIV+ men who have sex with men's (MSM) intentions to engage in unprotected sex.
  
  
  METHODS
  In a computer-based controlled experiment, 67 HIV+ MSM underwent a sexual arousal manipulation and indicated their intentions to engage in unprotected sex with hypothetical partners who differed in terms of HIV serostatus, physical attractiveness, relationship type, and preference for condom use.
  
  
  METHODS
  Computer-delivered questions assessed HIV+ MSM's intentions to engage in various sexual acts with each hypothetical partner.
  
  
  RESULTS
  As predicted, sexually aroused HIV+ MSM indicated stronger intentions to engage in unprotected sex than nonaroused HIV+ MSM; and having a partner who was attractive, HIV+, long term, or who preferred not to use condoms, also led to riskier intentions. Several significant interactions among these factors were found, which were generally consistent with predictions and with theory and research on cognitive processing and decision making.
  
  
  CONCLUSIONS
  These findings have implications for understanding risky sexual behavior among HIV+ individuals and for the development of interventions to reduce this risk.
