Dissociative identity disorder (DID) patients report experiencing chronic trauma in childhood which contributes to severe symptomatology in adulthood. These traumatic reactions are associated with validity and clinical scale elevations on a variety of psychological assessments. The Trauma Symptom Inventory-2 (TSI-2) measures posttraumatic stress symptoms, and has yet to be studied with a complex dissociative disorders (CDD) population. This study compared a group of CDD patients to coached DID simulators on the TSI-2. The CDD group had clinically significant elevations on a majority of the TSI-2 clinical scales and factors. Profile analysis revealed significant differences between CDD and coached simulator TSI-2 profiles. The TSI-2 ATR correctly classified 60 - 73% of participants, and specificity scores were unacceptably low. These results suggest that the TSI-2 may not be adequate at distinguishing feigned CDD from CDD.
