The article deals with the ethnopsychiatric clinical practice as an investigative and group therapy apparatus, as it has been carried out in France for over 30 years. The author, a psychologist and psychotherapist, briefly presents her encounter with ethnopsychiatry. Trained in Romania, where she practised for 16 years, the author immigrated to France and began a second apprenticeship in ethnopsychiatry with Professor Nathan, pupil and follower of Georges Devereux, psychoanalyst, anthropologist, ethnologist and founder of ethnopsychiatry. It presents Georges Devereux’s concept and its clinical application by his pupil, Tobie Nathan. Summarizing two clinical sequences, the author highlights the specificity of the patients as well as of the ethnopsychiatric consultation.
