The growing concern revolving around the dangers of sports-related concussions have led to the most recent implementation of neurocognitive (NC) test batteries as a means to objectively determine the presence of a cognitive defect. Whereas any other sports-related injury can be diagnosed with tools such as an x-ray or MRI, a concussion represents a metabolic disturbance that cannot be identified by these diagnostic tools. Many neurocognitive test batteries employ statistical techniques to derive cut off scores in order to represent significant or insignificant changes as compared to individual baseline scores, or pre-established normative values. If an individuals’ post-injury score exceeds the pre-determined RCI, he/she is classified as impaired suggesting a cognitive defect is present. The purpose of this study was to determine the clinical significance of a widely implemented NC test battery ImPACT using adjusted and unadjusted RCI methods and comparing composite indices for both overall RCI values and RCI values for different ranges of baseline scores. Ranges consisted of the lowest (0 – 20th percentile), middle (40th – 60th percentile), and highest (80th – 100th) quintile in a sample consisting of 56 NCAA Division I football players. Subjects each completed a baseline assessment at two different time points and composed a within-subjects sample.
