[Psychotherapeutic postrationalist approach to psychosis].

The article describes the heuristic contributions of the postrationalist psychosis model. It highlights the difference with other psychotherapeutic interventions in psychosis (phenomenological, psychoanalytic, cognitive) due to a change in epistemological perspective, in particular the distinction of domains, that of the observer and the observed, and the reconstruction of the subjective path that organizes a psychotic subject. The psychotherapy aims to contextualize the experience through the sequencing of the narrative to get an internalization of these experiences, lived in the crisis as external and alien to the self.
