The Trauma Symptom Inventory (TSI), Minnesota Multiphasic Personality Inventory-2 (MMPI-2), and Posttraumatic Diagnostic Scale (PDS) were administered to 71 women who reported histories of childhood and/or adult sexual maltreatment and 25 women who did not report a history of victimization. The TSI validity scales were not effective in identifying MMPI-2 defined invalid responding although were moderately related to MMPI-2 validity scales designed to identify similar response styles. In contrast, the TSI clinical scales displayed good convergent validity with conceptually related scales on the MMPI-2 and PDS. Also, the TSI added incrementally, albeit modestly, to the MMPI-2 in prediction of PDS defined PTSD. (Contains 5 tables.)
