title: HIV-Negative Partnered Men's Willingness to Use Pre-Exposure Prophylaxis and Associated Factors Among an Internet Sample of U.S. HIV-Negative and HIV-Discordant Male Couples.
abstract: OBJECTIVE
  Research on male couples' willingness to use pre-exposure prophylaxis (PrEP) is critically lacking.
  
  
  METHODS
  A cross-sectional 2011 Internet survey collected dyadic data from 275 HIV-negative and 58 HIV-discordant male couples to describe 631 HIV-negative partnered mens' willingness to use PrEP and associated couple-level demographic and behavioral factors with multivariate multilevel modeling.
  
  
  RESULTS
  Fifty-three percent were very to extremely likely to use PrEP. Willingness was positively associated with being in a mixed race and behaviorally non-monogamous relationship, and with amyl nitrate use with sex outside the relationship. Willingness was negatively associated with having a college education.
  
  
  CONCLUSIONS
  Prevention efforts should educate male couples about the potential benefits of PrEP.
