Abstract
This thesis shows how therapeutic work, in an existential psychodrama group, enables the therapist to access directly to “the-patients’-being”, without spending some time unravelling representations. In this context, the individual motion is triggered. Then, it transforms, via intersubjectivity, to place itself “between” (aida) the members of the group. There, it turns into a transubjective form which expands through resonance to deliver a peculiar climatic tone to the group. I have named that new dynamism: transubjective motion. As it functions dynamically according to the “opening-closing” poles, the transubjective motion permits the opening to the Feeling body space to the “common sense” space, enabling the patient to have a pacified relationship to the world around.In order to demonstrate our thesis and to model the concept, three researches-actions are presented (they were conducted among different populations: social workers, persons suffering from H.I.V and psychotic patients.) They reveal the operational value of the transubjective motion, situated at the heart of human intersubjectivity, whether it reveals itself in a crowd, between the members of a group, or the aida created by the therapist and his/her patient. Finally, those three researches-actions contribute, in clinical psychology, to the modelling of an emergent process of one’s being selfrealization through the relationship to the world around, expressing itself in the area of corporality.Beyond proposing a group therapy method -the existential psychodrama- this thesis analyses the conditions for its implementation (in terms of clinical intervention experience) in order to understand its therapeutic efficiency.
