The Good Participatory Practice (GPP) Guidelines were developed by AVAC and UNAIDS. They provide trial funders, sponsors, and implementers with systematic guidance on how to effectively engage with all stakeholders in the design and conduct of biomedical HIV prevention trials. The guidelines are available in multiple languages. AVAC has also developed an array of supplementary GPP tools tools.
Cognitive mapping is a participatory research methodology that documents, in visual form, a construct of the local environment in which people live and work. The authors adapted this method to provide detailed data about study locales to inform recruitment and retention strategies for HIV prevention community based clinical trials.
