Longitudinal Associations among Posttraumatic Stress Disorder Symptoms, Traumatic Brain Injury, and Neurocognitive Functioning in Army Soldiers Deployed to the Iraq War.

摘要: Objectives: Military deployment is associated with increased risk of adverse emotional and cognitive outcomes. Longitudinal associations involving posttraumatic stress disorder (PTSD), relatively mild traumatic brain injury (TBI), neurocognitive compromise are poorly understood, especially regard to long-term outcomes, rigorous research necessary better understand the corresponding relationships. The objective this study was examine short-term (>5 years) longitudinal among PTSD, performance, TBI following military deployment. Methods: In prospective study, N=315 U.S. Army soldiers were assessed at installations before (2003–2005) after (2004–2006) an index Iraq War, again average 7.6 years later (2010–2014) as a nationally dispersed cohort active duty soldiers, reservists, veterans. Thus, design allowed for two measurement intervals over which changes. All assessments included PTSD Checklist, civilian version, individually-administered performance-based tests. history derived from clinical interview. Results: Autoregressive analyses indicated that visual reproduction scores inversely related subsequent symptom severity assessments. Conversely, increases in each interval poorer verbal and/or recall end interval, less efficient reaction time post-deployment. TBI, primarily sample, outcomes both post-deployment follow-up. Conclusions: These results suggest relationships symptoms, decrements may contribute sustained symptoms time. (JINS, 2018, 24, 311–323)
