In the treatment group, the GPs receive training in executing narrative exposure therapy by specialized psychologists. The doctors of this group will hold three 45-minute therapy sessions with their patient within 6 weeks. During the first session a list of the most intense events - both positive and negative - is drawn up in the life of the patient on the basis of a life line, with the stay at the intensive care unit being one of these events. During the second session the experience in the intensive care unit will be discussed in detail, led by the GP. During the third session, another event from the patient's life is dealt with in the same manner. This way, the different components (cognitions, emotions, body reactions, context information) can be reconnected and classified into the patient's own biography. Between therapy sessions, the GP and the psychologist will schedule a conversation for Support of the GP during the therapy. In order to monitor the patient's safety and compliance, standardized telephone calls between the patient and the GP's practice are regularly carried out every 2-3 weeks in between the therapies sessions and up to the first data collection after 6 months (T1).
