The role of network communication in mediating the effect of a social network intervention on HIV seroconversion among people who inject drugs in Ukraine
Background
We examined the role of network communication about HIV-related topics in mediating the efficacy of a social network intervention on HIV seroconversion among people who inject drugs (PWID) in Ukraine, where Eastern Europe’s second-largest HIV epidemic is concentrated among PWID.
Methods
We used randomized controlled trial data from 1200 HIV-negative PWID (Ukraine; 2010–2012) in an inverse-odds weighted analysis to examine mediation by network communication.
Results
Network communication mediated 24 % (95 % CI= 19.22–29.38) of the intervention’s effect.
Conclusions
Integrating training to support network communication about additional HIV prevention resources could enhance the impact of social network HIV prevention interventions among PWID.
期刊介绍：
Social Networks is an interdisciplinary and international quarterly. It provides a common forum for representatives of anthropology, sociology, history, social psychology, political science, human geography, biology, economics, communications science and other disciplines who share an interest in the study of the empirical structure of social relations and associations that may be expressed in network form. It publishes both theoretical and substantive papers. Critical reviews of major theoretical or methodological approaches using the notion of networks in the analysis of social behaviour are also included, as are reviews of recent books dealing with social networks and social structure.
