The interviews will be conducted in face to face at home, at the hospital or in any other place (depending on the choice of the participants). The different conditions in which the interviews will be conducted will be all clearly identified and included in each recording: time, place, positioning of the actors, and context (family presence, disturbing environment). Interviews will be digitally recorded and will be transcribed by a secretary. According to that comprehensive approach, categories will be not identified in advance but derived from the data.
