[Assessment of complex posttraumatic stress disorder with the revised Trauma Symptom Inventory (TSI-2)].

BACKGROUND: This study tested whether it is possible to diagnose complex posttraumatic stress disorder (CPTSD) according to the beta version of ICD-11 by means of the Trauma Symptom Inventory 2 (TSI-2). Currently, there is no established measurement for this.

METHODS: An algorithm for the TSI-2 was developed. This was tested in a sample of 100 psychiatric patients, who had experienced aversive and/or traumatic events. The frequency of CPTSD and differences regarding gender, age and traumatic events will be reported.

RESULTS: On the basis of this TSI-2 algorithm, 5% of the sample were estimated to suffer from CPTSD. A trend towards more women being affected was observed, and younger patients were more affected than older ones. Traumatized individuals reported more mental health problems than non-traumatized ones.

CONCLUSION: Tentatively, these results indicate that it may be possible to use a combination of certain scales of the TSI-2 to diagnose CPTSD in line with its current definition by the ICD-11.
