Popis: OBJECTIVE The primary aims of this study were to identify latent profiles of acute stress disorder (ASD) symptoms and to evaluate postconcussive symptom differences across the identified profiles as measured by the Acute Stress Disorder Scale and the Military Acute Concussion Evaluation, respectively. METHOD Participants (N = 315) in the current study were predominantly active-duty (75.0%), enlisted (97.8%) males (97.4%) serving in the U.S. Army (87.8%). Approximately, half of the sample reported being married or engaged (51.1%) and was on average 25.94 (SD = 6.31) years old. Participants were referred to the Air Force Theater Hospital, 332nd Air Expeditionary Wing, Joint Base Balad, Iraq, to be evaluated as part of routine clinical assessment for neurocognitive and psychological symptoms following exposure to a blast. RESULTS A 3-profile solution was identified as the most parsimonious and best-fitting model based on statistical model fit indices. Blast injured service members in Profile 3 had greater ASD total and subscale severity compared to the other 2 subgroups, with effect size estimates largely differing by hyperarousal and reexperiencing symptoms. Furthermore, Profiles 2 and 3 were more likely to demonstrate postconcussive symptoms compared to Profile 1. CONCLUSIONS Findings provide novel information on heterogenous ASD symptom profiles during the acute phase following a blast injury and highlight the relationship between psychological and physical symptoms. Classification of blast-injured service members may help identify at-risk individuals who would benefit from further clinical care and mitigate long-term psychological and neurocognitive issues.
