The aim of the project is to evaluate the psychometric properties (e.g. validity, reliability) of the International Trauma Interview (ITI) - German version. The ITI is a structured clinical interview that corresponds to the ICD-11 criteria for diagnosing both posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD). Eligible participants from psychiatric inpatient and outpatient facilities in Switzerland who have provided informed will complete various self-report measures about trauma-related mental health complaints. In addition, the ITI will be conducted by a trained clinician. Lastly, information from the medical chart will be further used for scientific purpose. The overall assessment will take approximately 1-2 hours to complete.

The ITI consists of 18 items and for each symptom, standardized questions as well as probes are presented. A trained professional rates both symptom frequency and intensity, which are converted into an overall index of symptom severity. A diagnosis of PTSD/CPTSD is established by applying the ICD-11 diagnostic rules. It takes approximately 30-60 minutes to administer.
