Objective - Participatory approaches are increasingly used during policy development to improve stakeholder ownership and compliance. This is particularly the case for integrated surveillance systems (ISS), which require reconciling the expectations and values of a wide range of stakeholders. However, there is a lack of evidence on the impact of such approaches. In this context, we developed and applied a framework to evaluate a participatory process that supports the development of an ISS, using the case study of anthrax in Burkina Faso. Materials and Methods - The evaluation attributes were identified by conducting a literature review of (i) existing frameworks for the evaluation of public policies and surveillance systems, and (ii) the expected benefits of participatory approaches.. For each attribute, criteria were identified to enable their evaluation. Methods were then defined for measuring these criteria. Finally, the framework was validated by a panel of experts and applied in Burkina Faso. Results - The framework includes 13 attributes that are classified into 3 categories: quality of the system produced by the participatory process, impact of the process on the participants, and benefits perceived by participants. Each attribute is assessed using from 3 to 5 criteria. Its application to anthrax surveillance in Burkina Faso showed that the participatory process led to the identification of well-adapted and accepted surveillance modalities. Participants improved their knowledge and mutual understanding. Most of them recognised the value of such an approach in moving towards a relevant and sustainable ISS. Conclusion - The evaluation framework has proved to be efficient to evaluate the impacts of the participatory process. However, long-term impacts (e.g., performance of the system and capacities of actors) will require a longer timeframe for their evaluation. The framework also allows to identify weaknesses of the process and bias in the outputs produced, su
