Abstract There is a dearth of studies investigating the latent structure of Acute Stress Disorder (ASD) following the changes in the fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5). To date, there is no consensus on the best representation of ASD. This study addressed this gap by examining four latent ASD models in a sample of war-exposed individuals (N = 424). Investigation on the relationship of the best-fitting model to functionality in the latent level was also conducted. The five-factor model, composed of intrusion, avoidance, numbing, dysphoric arousal, and anxious arousal factors, yielded the best-fitting model. Latent associations between the factors of the model and functionality suggest that symptoms of functionality do not significantly affect the factor structure of ASD. These findings have implications for understanding the underlying mechanism of ASD and can inform the development of more nuanced trauma-related interventions, particularly addressing ASD symptoms and functionality separately.
