Outcome Measures

Primary Outcomes (2)

  • severity of PTSD symptoms

    Clinical-Administered PTSD Scale for DSM-5 (CAPS, Blake etal., 1998), presence of PTSD and score for severity of PTSD symptoms

    baseline (pre-intervention), post-intervention (after 16 psychotherapy sessions or for waiting group after 4 months) and follow-up (after 6 months)

  • Remission of PTSD diagnosis

    Clinical-Administered PTSD Scale for DSM-5 (CAPS, Blake etal., 1998), presence of PTSD diagnosis (cut-off score lower than 23)

    baseline (pre-intervention), post-intervention (after 16 psychotherapy sessions or for waiting group after 4 months) and follow-up (after 6 months)

Secondary Outcomes (3)

  • subjective PTSD symptoms

    baseline (pre-intervention), post-intervention (after 16 psychotherapy sessions or for waiting group after 4 months) and follow-up (after 6 months)

  • severity of psychosis

    baseline (pre-intervention), post-intervention (after 16 psychotherapy sessions or for waiting group after 4 months) and follow-up (after 6 months)

  • Wellbeing

    baseline (pre-intervention), post-intervention (after 16 psychotherapy sessions or for waiting group after 4 months) and follow-up (after 6 months)

Study Arms (2)

Waiting control group

NO INTERVENTION

The patients in the treatment-as-usual control group remain on the waiting list for 14 weeks after the baseline measurement. After 14 weeks, they participate in the study diagnostics post-treatment at time point.

Intervention group

EXPERIMENTAL

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.
