简要总结
This will be a two-arm cluster randomized controlled trial. The control group can share their Center for Disease Control and Prevention certified online HIV results (COHIV) with another party freely through a social networking tool, while the intervention group will be asked for the COHIV before he can see the COHIV of his friend. The investigators hypothesize that the requires exchange will promote HIV testing and thus reduce HIV incidence among MSM.
详细描述
This will be a two-arm cluster randomized controlled trial. A WeChat-based mini program has been developed to send and receive Center for Disease Control and Prevention certified online HIV results (COHIV). WeChat is the ubiquitous communication and social networking tool in China. We will use the social network method for participant recruitment. A social network consists of one ego and some alters, and in this study a social network will be considered as a cluster. In a social network, ego is the MSM who shares his certified HIV test results with or without exchange mechanism by the WeChat mini program, while alters are recipients of the shared links. So the ego can shares his COHIV with many alters. After an ego shares the certified HIV test result with exchange mechanism (intervention group) or without exchange mechanism (control group) with their WeChat contactors, the people who click the link will be candidate alters in our study. 1020 alters will be recruited as the participants and the randomization would be based on the unit of social network, which means the alters will be randomized into the same group that the ego is in.
Participants in the intervention group will receive his friend's COHIV and can only open it when the participants share their own in exchange. If the participant already has the COHIV, the system will lead the user to send his COHIV to the friend. If the participant does not have the COHIV, the system will guide him to make online appointment at the testing clinic. The participants in the control group will be able to receive and open the friend's COHIV entirely at the friend's discretion without the mandatory exchange requirement. The system will also guide users on how to get an HIV test by making appointments with the MSM friendly clinics in the mini program. Questionnaires are scheduled at baseline, month 3, 6 and 9. Follow-up questionnaires will be delivered through WeChat. The primary outcome is HIV testing rate of the participants in the past three months.

研究组 & 干预措施
Intervention group
Men will be required to exchange the Center for Disease Control and Prevention certified online HIV results (COHIV) with friends conditionally.
干预措施: COHIV with exchange mechanism (Behavioral)
Control group
Men will share the Center for Disease Control and Prevention certified online HIV results (COHIV) with friends freely without conditional exchange requirement.
干预措施: COHIV without exchange mechanism (Behavioral)
