abstract = {PRIMARY OBJECTIVE: To examine differences between the baseline-referenced and norm-referenced approaches for determining decrements in Automated Neuropsychological Assessment Metrics Version 4 TBI-MIL (ANAM) performance following mild traumatic brain injury (mTBI). RESEARCH DESIGN: ANAM data were reviewed for 616 US Service members, with 528 of this sample having experienced an mTBI and 88 were controls. METHODS AND PROCEDURES: Post-injury change scores were calculated for each sub-test: (1) normative change score = in-theater score - normative mean and (2) baseline change score = in-theater score - pre-deployment baseline. Reliable change cut-scores were applied to the change and the resulting frequency distributions were compared using McNemar tests. Receiver operator curves (ROC) using both samples (i.e. mTBI and control) were calculated for the change scores for each approach to determine the discriminate ability of the ANAM. MAIN OUTCOMES AND RESULTS: There were no statistical differences, p \< 0.05 (Bonferonni-Holm corrected), between the approaches. When the area under the curve for the ROCs were averaged across sub-tests, there were no significant differences between either the norm-referenced (0.65) or baseline-referenced (0.66) approaches, p \> 0.05. CONCLUSIONS: Overall, the findings suggest there is no clear advantage of using the baseline-referenced approach over norm-referenced approach.},

The present study included a sample of 142 active-duty service members evaluated following a suspected or confirmed history of mild traumatic brain injury. Participants completed a battery of neuropsychological measures that included scales of performance and symptom validity (specifically the Medical Symptom Validity Test, Nonverbal Medical Symptom Validity Test, and Personality Assessment Inventory). Among the factors considered in the current study, performance validity test results accounted for the most variance in cognitive test scores, above demographic, concussion history, symptom validity, and psychological distress variables. Performance validity test results were modestly related to symptom validity as measured by the Personality Assessment Inventory Negative Impression Management scale. In sum, the current results replicated the original Cooper et al. study and highlight the importance of including performance validity tests as part of neurocognitive evaluation, even in clinical contexts, within this population.},

abstract = {Since the terrorist attacks of September 11, 2001, 1,348,405 citizens have been deployed to combat in Operation Iraqi Freedom (OIF), Operation New Dawn in Iraq, and Operation Enduring Freedom in Afghanistan (OEF). During this same period 266,810 (20%) of these individuals have been diagnosed with a traumatic brain injury (TBI). The majority of these were Army soldiers, with 155,282 (58%) receiving the diagnosis. Mild TBI comprised 82% of the total, with the remainder being moderate to severe. Over this same period the Department of Defense (DoD) has invested $374.9 million to enhance access and quality of care services, including 57 TBI treatment centers in the combat theater and throughout the U.S. The Army's medical research division, the Medical Research and Material Command (MRMC), has invested an additional $700 million to TBI research during this time. The effort has faced a number of challenges, including limited human subject basic and translational research, limited epidemiological data on combat-related injuries, limited capacity and standards for data acquisition, and a lack of standardized evidenced-based protocols for treatment. All these areas have undergone significant growth and development, leading to the comprehensive system of care present today. A further challenge in this patient population has been the clinical co-morbidity of TBI, post-traumatic stress disorder, and chronic pain syndrome. The Army and the DoD have created treatment programs that are interdisciplinary in clinical approach, targeting particular neuropsychological domains of dysfunction rather than diagnostic category or etiology of injury. This article presents the history of this effort, the challenges to accurate and adequate diagnosis and care that remain, and the future of brain injury clinical and research efforts in the military.
