From my experience I think the community has different levels of knowledge and engagement in clinical trials. We need to be open and sensitive to know their understanding. Promoting literacy research to the stakeholders is one of the goals and it is possible through meetings, participation in local and international conferences where they can learn and exchange experiences. In this way, stakeholders can do feel their involvement throughout the research process. In our CAB, in some monthly meetings, we open the invitation to others community leaderships who are not directly related to the clinical trial. In this meeting, we update currently protocols and the new trials. Language is still a big issue and we use all tools that can make an easier understanding. If necessary are used graphic material and pictures to help with explanations.
