Abstract Text:

Post-traumatic stress (PTS) symptoms are common after a traumatic brain injury (TBI). However, most literature focuses on mild TBI, and many PTS measures share common items with overlapping TBI symptom sequelae. This study used a transdiagnostic approach to reduce heterogeneity and improve multidimensionality among PTS measures for a moderate/severe TBI population.
This study used participants enrolled in the TBI Model Systems and The Characterization and Treatment of Chronic Pain after TBI. Exploratory factor analysis (EFA) was performed to identify new structures of PTS and confirmatory factor analysis (CFA) to validate the model fit. Global fit indices were calculated for all structures.
The EFA identified a single-order, second-order, and bifactor structure that showed very good model fit. However, the original parent structures showed similar fit for each respective structure. The hierarchical, second-order structure was deemed the most optimal identified model.
The transdiagnostic approach of this study identified a structural model of PTS symptoms for a moderate/severe TBI population. These findings may help improve predictive modeling, research, and treatment options.
