Perceived facilitators of decision-making and usage of biomedical HIV prevention strategies: findings from an online, qualitative study with same-gender male couples in the United States.

The early stages of gay and bisexual men's relationships are a critical period for communicating about HIV prevention strategies. This study sought to: (1) explore facilitators to decision-making to use prevention strategies and (2) describe the prevention strategies being used by same-gender male couples in new relationships. Individual interviews were conducted with 76 partnered men, representing 37 couples and 2 individuals. Couples had been together for one year or less, and varied by U.S. geographical region of residence and HIV serostatus: 8 seroconcordant positive, 17 seroconcordant negative, and 13 serodiscordant couples. Two overarching qualitative themes emerged: (1) communication and (2) information and resources. Notably, few couples had both partners mention the same facilitator. The most commonly used HIV prevention strategies were treatment as prevention for partners in seroconcordant positive and serodiscordant couple relationships, and HIV/STI testing for partners of seroconcordant negative couples. Compared to the other two couple groups, fewer seroconcrdant negative couples were aware of each other's use of strategies. Study findings suggest these facilitators are important to include in future interventions. Efforts are also needed to improve within-dyad awareness about which strategies partners are using and how they may best support one another toward their sexual health goals.
