Author(s): Weili Lu*, Kim T Mueser, Yuane Jia, Philip T Yanos, Amanda Siriram, Deanna Bullock, Ke Wang, Steven M Silverstein, Jennifer Gottlieb, Krista Rogers, Pouya G Aftab and Stanley D RosenbergPosttraumatic Stress Disorder (PTSD) is highly prevalent and contributes to worsened impairment among individuals with serious mental illness (SMI; e.g., schizophrenia, schizoaffective disorder, bipolar disorder, treatment refractory major depressive disorder). However, previous research has not examined the factor structure of PTSD symptoms in SMI populations. This review summarizes a published article evaluating the factor structure of PCL in two large SMI samples (N=11425; n=842 in study 1, n=583 in study 2). The latest edition of the DSM-5 4-aspect framework was shown to be the most appropriate one for PTSD amongst individuals suffering from SMI, exhibiting consistent measurement results across ethnic background, classifications of diagnosis, and generations. The review further discusses the suitability of DSM-5 4-factor model of PTSD among people with SMI, as well as future directions for PTSD research among this population.
