Effectiveness of Trauma Therapy Using Prolonged Exposure for Patients With PTSD and a Comorbid Psychotic Disorder

In the intervention condition, patients are treated directly after the baseline measurement by Prolonged Exposure in 16 hours of individual therapy. The 16 individual therapy sessions will take place in 1 to 2 sessions per week over a period of 7 to 16 weeks. The individual therapy sessions are videotaped with camera focus on the therapist. Parts of the Prolonged Exposure process (the re-experiencing of the traumatic memory) are recorded on tape, so that the patient can listen to the recording as homework at home. Afterwards, the patients take part in a study diagnostic session.
