1. POSTER TEMPLATE BY: www.PosterPresentations.com The Ins and Outs of Analyzing A Large Dataset of Military Personnel from Camp Lejeune Andrea Mejia, Hana Kuwabara, Angela Sekely, Zara Melikyan, Antonio E. Puente, Ph.D. Introduction Objective Summary Future Directions An increasing number of military service members are surviving injuries from Improvised Explosive Devices (IED) including those delivered by vehicles and indirect-fire attacks such as mortar fire and rocket- propelled grenades These individuals tend to display long-term effects of traumatic brain injuries (TBI) and/or acquire long-term health problems such as post-traumatic stress disorder (PTSD) References The current dataset contains over 1000 individuals, more than 150 variables and close to 1,000 data points per person. This study explores demographics and descriptive information of a community based sample of active duty military members who were referred to clinical neuropsychologists because of reported cognitive and psychological changes post deployment. This study also describes the process of obtaining the forthcoming dataset To this date, 504 files out of 1,017 have been coded and checked for inter-rater reliability.

(2006). A compendium of neuropsychological tests (3rd ed.). Oxford University Press. Currently the lab is finishing recoding the dataset which will be used for future research A process that has taken over 8 years A total of over 15 research assistant Demographics of present sample matched Marine Corps demographics from Camp Lejeune Of interest, most individuals have been deployed one to two times Common symptoms among this population include headaches and sleep disturbances The majority reported symptoms An example of interfacing a professional practice with a university training site To this date, active duty medical staff members have not been provided with empirically derived information from large datasets to understand and treat individuals with PTSD/TBI There is limited information of the effects of combat related PTSD/TBI Data was compiled via a private practice associated with Camp Lejeune, North Carolina. All individuals participated through the Tricare health care program and were referred by various military neurologists or other medical officers. Participants were tested between 2004 - 2014 The descriptive demographics include: Basic demographics Symptoms Blast profile ASVAB scores The evaluation procedure is a modified neuropsychological “Blast” battery which includes 3 hours of clinical interview and 7 hours of neuropsychological tests administered over two separate testing sessions.
