Abstract
Restitution is not seen as the sole outcome of research but as a determining process in the course of action-research-training, or research "with" field actors. Indeed, these field actors are not only objects but also subjects of and within the research, actively participating in the approach by contributing their remarks, disagreements, and insights to the restitution process. The diversity of contexts and the specificity of intervention requests depending in the fields allow for addressing multiple forms of restitution, whether individual/collective, formal/informal, oral or written, as well as its different time and space settings.
