Posttraumatic stress disorder and noncredible symptom reporting on the Trauma Symptom Inventory-2.

This archival study sought to investigate the ability of raw scores on the Atypical Response scale (ATR) and TRAUMA Factor of the Trauma Symptom Inventory-2 to predict noncredible cognitive performance validity testing (PVTs) in personal injury litigants and disability claimants with posttraumatic stress disorder (PTSD). Participants included 51 adults diagnosed with PTSD who underwent comprehensive neuropsychological examination. Criterion groups were formed based upon passing (Credible Group) or failing (Noncredible Group) cognitive performance validity tests (PVTs).
