GPS: Gay Poz Sex

This study will provide preliminary data on the effect size of a sexual health promotion program for HIV-positive gay, bisexual, and other men who have sex with men (MSM). This community-based research study is directed by the Poz Prevention Working Group, a group with a majority membership of HIV-positive gay men, which is associated with the Gay Men’s Sexual Health Alliance (GMSH). The Poz Prevention Working Group and GMSH work to promote sexual health and prevent transmission of sexually transmitted infections and HIV among HIV-positive gay and bisexual men.

GPS is a sexual health promotion program, which uses a group counselling format with HIV-positive gay men as peer facilitators. GPS participants have told us they have really enjoyed the program, and preliminary data shows that it reduces participants’ feelings of loneliness may help to improve sexual health outcomes. GPS is currently being evaluated through a randomized controlled trial (RCT) in Toronto and Vancouver. Data collection on this study ended in July 2018 and we are currently analyzing the results, which will be shared here and on the GPS website

Dr. Hart is Principal Investigator on this study with Co-Principal Investigator, Dr. Barry Adam, Director of Prevention at the Ontario HIV Treatment Network and University Professor at the University of Windsor.

This study was supported by the Canadian Institutes of Health Research, the Ontario HIV Treatment Network, the Canadian HIV Trials Network, and the CIHR Centre for REACH in HIV/AIDS.
