The ability to accurately and efficiently evaluate neurocognitive status of US Warfighters exposed to diverse operational and experimental conditions is of critical importance to the ongoing mission and Force 2025 objectives of the United States military. The Automated Neuropsychological Assessment Metrics ANAM is a computer assisted tool for evaluating neurocognitive performance with demonstrated effectiveness for application in a wide range of military operational and research testing scenarios. The primary objective of this project is to examine select psychometric and administration properties of the ANAM4. Four studies were proposed as part of this overall effort 1 examine common use practices and determine the effect of specific administration procedures on ANAM4 performance 2 assess the test-retest reliability and practice effects of individual ANAM4 test modules 3 examine the validity of the ANAM4 Mood Scale, and 4 establish a representative normative dataset of ANAM4 performance outcomes specifically for use with Army National Guard service members. Data collection for Studies 1-3 is complete data collection for Study 4 is completed in 4 states Minnesota, Maine, Arizona, Montana, nearing completion in Kentucky and Texas, am dos commencing in New Hampshire. The Study 4 protocol procedures are currently pending approval in Pennsylvania. Data analyses and manuscript preparation for all four studies is ongoing, with all primary data analyses completed and manuscripts nearing completion for Studies 1-3.
