Surveillance systems rely on a network of stakeholders who share information. Socioeconomics factors have an influence on their decision to share or not the information within the system. Those factors are rarely taken into consideration, especially in the evaluation of surveillance systems. Participatory approaches derived from social sciences have proven useful to take these factors into account and have been adapted over the past 15 years to the context of health surveillance system evaluation. The “AccePT” (Acceptability Participatory Toolkit) method based on participatory approaches has been developed to assess the acceptability of surveillance systems. The method takes into consideration the adequacy of objectives and operation in the system for the stakeholders, the satisfaction of their roles, and their level of trust within the system. This approach allows stakeholders to freely discuss or think about how they experience working or not working with other partners, and to provide context-based recommendations taking into consideration their perceptions, expectations, and needs.
