[Psychotherapeutic approach to migrant patients of the 1st or 2nd generation: contribution of Tobie Nathan's ethnopsychoanalysis].

Based on our experience of the ethnopsychiatric consultation directed by Tobie Nathan in Paris, we try to define the adaptations of the therapeutic setting necessary, according to him, in a transcultural situation, and by whom we can be inspired (work-group, participation of a translator, mobilisation of the traditional etiological interpretations). Then, we study the clinical case of a young Algerian girl living in Belgium. We analyze her acute delirious psychosis following the conceptions of Tobie Nathan: the particular situation of migrant children would be a proneness for the splitting of the ego. At least we show how important is in the psychotherapy the restitution of the original cultural framework.
