Haoyu accurately describes what we have done to date in terms of community engagement — which is engage with the “obvious” community groups who have experience engaging with the clinical research sites already. A stakeholder mapping exercise will be a critical first step and mapping would be useful to conduct both at the national level and at each of the sites. I think it will be useful to think of typologies of stakeholders (local CDC, local CBOs, academic centers, hospitals) and their theoretical importance; then working with local contacts in each site, figure out which actual organization are in operation in that geographic location and figure out how to engage them. One of the stakeholder types whom we engaged early on and would now like to re-engage are social networking sites in China, particularly those focused on MSM, whether they are hook up sites or cultural information exchange type sites. I would be interested whether others have experience engaging these type of websites and whether these types of entities have been useful to engage as stakeholders.
