Dramatherapy is a creative and embodied approach to social and psychological intervention that leverages theatrical techniques to promote psychological, social, and emotional well-being. Rooted in the works of Jacob L. Moreno’s psychodrama and Augusto Boal’s Theatre of the Oppressed, among others, dramatherapy provides participants with a space for self-expression, catharsis, and transformation. This chapter first explores key theoretical foundations of dramatherapy, emphasizing its potential to foster both individual and collective change. It then examines its practical applications within the framework of clinical sociology, drawing on our action-research projects. The second part of the chapter presents three case studies. The first focuses on the ECAD (Expression Corporelle Adaptée et Désengagement Scolaire—Adapted Body Expression and School Disengagement) project and the doctoral research that followed, investigating how dramatherapy techniques can help students develop self-confidence and social integration in educational settings. The second case study explores dramatherapy among pre-bariatric patients, examining how theatrical methods contribute to reshaping body image perceptions, addressing emotional eating, and enhancing psychological well-being in individuals preparing for weight-loss surgery. The final case study delves into dramatherapy interventions with individuals affected by rare diseases, specifically Myasthenia Gravis, illustrating how the performative space enables participants to articulate their embodied experiences of illness and reimagine their identities beyond the constraints of medical narratives. By analysing these three contexts, this chapter highlights the versatility of dramatherapy in addressing diverse psychosocial challenges. The concluding section discusses practical implications and methodological considerations.
