ABSTRACT
BACKGROUND:
Trauma and posttraumatic stress disorder (PTSD) are common among individuals with serious mental illness (SMI; e.g., schizophrenia, schizoaffective disorder, bipolar disorder, treatment refractory major depressive disorder), with resultant functional impairment. Previous studies have not evaluated the factor structure of the PTSD Checklist (PCL) among persons with SMI.AIMS:
This study evaluated the factor structure of the PCL in two large SMI samples from public mental health treatment sectors screened for PTSD using the PCL.METHODS:
Four different models of PTSD were tested using confirmatory factor analyses.RESULTS:
Results indicated that the DSM-5 4-factor model (intrusion, avoidance, numbing, and hyperarousal) had the best fit. Further, the DSM-5 4-factor model demonstrated measurement invariance.CONCLUSIONS:
Results supported the suitability of the DSM-5 4-factor model of PTSD among people with SMI.Palavras-chave
