Our research project gives an account of the functioning of forum theatre and its intra- and intersubjective level dynamic processes within the framework of a qualitative arts-based participative action research. During the intervention, information has been gathered on the tools of forum theatre that improve self-efficacy to highlight the techniques of participation in the creative work. The present article shows the theoretical and institutional framework of the project, introduces the participants, sheds light on the methods applied and gives insight into the findings and conclusions.
