An Evaluation of the Consistency and Reliability of the Defense Automated Neurocognitive Assessment Tool.

A durable, portable, and field-hardened computerized neurocognitive test (CNT) called the Defense Automated Neurobehavioral Assessment (DANA) tool was recently developed to provide a practical means to conduct neurological and psychological assessment in situ. The psychometric properties of the DANA have been previously described. This present work discusses the test-retest reliability of the DANA Rapid test battery, as administered to a homogeneous population of U.S. Air Force Academy football team players (N = 162) across the duration of the season. The intraclass correlation coefficient (ICC) metric of the DANA is compared with that from two different CNTs recently reported in Cole et al., and the implications of using the metric to interpret comparative test reliability among different CNTs are discussed.
