Abstract

To assess the relationships between post-traumatic stress disorder (PTSD) components, Hierarchical Taxonomy of Psychopathology (HiTOP) spectra, and dysfunctional personality domains, the Post-Traumatic Checklist for DSM-5 (PCL-5); the Personality Inventory for DSM-5-Brief Form+ (PID-5BF+); and self-report measures of HiTOP Internalizing, Thought Disorders, and Externalizing spectra were administered to 387 trauma-exposed Italian community-dwelling women. Before structural equation modeling (SEM), measurement components of models were assessed using confirmatory factor analyses. Both taxometric and Gaussian mixture analysis results were consistent with a dimensional representation of the PCL-5 scores. SEM results showed that PTSD components, at least as they were operationalized by the PCL-5 scores, were positively, significantly, and substantially associated with HiTOP Internalizing and Thought Disorder Spectra latent dimensions, as well as with Negative Affectivity, Detachment, and Psychoticism personality domains.
