- PTBS Symptom Severity [ Time Frame: change from pretreatment to posttreatment (planned duration 12 weeks on average) to follow-up (six months after posttreatment) ]Even though participants are assessed by a clinical interview before entering the study, the primary outcome measure is the PDS which is applied before and after treatment as well as at 6-month follow-up.
- PTSD Symptom change (IES-R) [ Time Frame: change from pretreatment to posttreatment (planned duration 12 weeks on average) to follow-up (six months after posttreatment). Also measured at each session (up to 24 time points between pre- and posttreatment). ]The IES-R is a short instrument for the measurement of PTSD symptom severity. In this study, the IES-R is applied before every session in order to measure symptom change over the time of the therapy.
- Brief Symptom Inventory [ Time Frame: change from pretreatment to posttreatment (planned duration 12 weeks on average) to follow-up (six months after posttreatment) ]The Brief Symptom Inventory (BSI) is a measure of general psychological distress.
- Inventory of Interpersonal Problems (IIP) [ Time Frame: change from pretreatment to posttreatment (planned duration 12 weeks on average) to follow-up (six months after posttreatment) ]The IIP is a widely used instrument to measure interpersonal distress.
