Qualitative Health Research, Ahead of Print.
A qualitative egocentric social network approach was taken to explore motivations for pre-exposure prophylaxis (PrEP)-related communication between women who inject drugs and network members. Eligible participants were HIV-negative, 18 years or older, and participating in a PrEP demonstration project in Philadelphia, PA, USA. The study employed content analysis of in-depth interviews to identify themes related to contextual and relational factors impacting PrEP communication within networks. Participants (n = 20) named on average three network members, resulting in a total of 57 unique relationships. PrEP conversations occurred within 30 of the 57 relationships, and motivations were to benefit others, to benefit themselves, and due to a sense of obligation. Some conversations also occurred when a peer unexpectedly found their pills. Taking a qualitative approach to network analysis provided a nuanced understanding of how interpersonal characteristics motivated PrEP conversations. Network interventions that facilitate information diffusion and social support may increase PrEP uptake and adherence among women who inject drugs.
