Subject: Outpatient psychological dataset of active Marines and navy personnel *Message body: *In this dataset, 893 active duty military personnel were administered a comprehensive evaluation that included extensive premorbid functioning (e.g., Armed Services Vocational Aptitude Battery (ASVAB)), structured interview, as well as psychological and neuropsychological testing post-deployment. This dataset was compiled by the Roger W. Sperry Neuropsychology Laboratory at University of North Carolina Wilmington (UNCW) in collaboration with neuropsychologists in Carolina Psychological Health Services (CPHS), a private practice serving service members assigned to Military Base Camp Lejeune, Jacksonville, NC. Participants were referred to CPHS by military neurologists and other qualified medical officers from Naval Hospital Camp Lejeune for neuropsychological evaluation due to reported cognitive deficits as a result of military deployment (e.g.,. head injury due to blasts). Premorbid (e.g. ASVAB) and demographic variables (e.g., education) were gathered. Participants were interviewed and then administered a neuropsychological blast battery that was developed with input from neuropsychology colleagues at the Walter Reed National Medical Center. The battery provided a comprehensive assessment of the following neurocognitive domains: effort, emotional functioning, personality, executive functions, intelligence and achievement, learning and memory, and motor functioning (see Table 1 for the list of tests used to assess these cognitive domains). A total of 18 demographic variables were obtained and 17 tests were administered. Individual raw, cumulative, and standardized scores from the assessments were collected. In addition to this, 117 re-assessments were conducted and entered into the dataset. For a detailed description of the dataset, please see Puente, A. E., Sekely, A., Chen, C., Wang, Y., & Steed, A.
