Latent factor structure of PTSD symptoms in veterans with a history of mild traumatic brain injury and close-range blast exposure.

ABSTRACT:

Objective

Confirmatory factor analysis (CFA) has previously been employed to examine the latent factor structure of posttraumatic stress disorder (PTSD) symptoms with mixed results. A limited number of studies examined PTSD factor structure among veterans of recent military conflicts. This study examined the relationship between PTSD factor structure and the hallmark conditions of these conflicts, mild traumatic brain injury (mTBI) and close-range blast exposure (CBE).

Method

The fit of previously proposed PTSD factor models was compared in a cohort of 387 combat-exposed veterans, with stratified analyses comparing factor structure models between those with a history of military-related mTBI and CBE (n = 106) and those without either of these antecedents (n = 151). CFAs were
