<p><b>Objective:</b> To assess the construct validity of Tool 5 (SCAT5) cognitive items in a healthy sample of NCAA Division I student-athletes from a single institution.</p> <p><b>Design:</b> Cross-sectional.</p> <p><b>Setting:</b> NCAA Division I University.</p> <p><b>Participants:</b> Deidentified data were analyzed for 657 (n = 301 male; 19.2 ± 1.4 years old) healthy NCAA Division I student-athletes who provided consent for use of their preparticipation SCAT5 results during the 2017-2018 and 2018-2019 academic years for research purposes. No individuals were excluded from our analyses.</p> <p><b>Independent Variables:</b> Baseline cognitive item scores [Orientation Total (0-5), Immediate Memory (0-30), Delayed Recall (0-10), Digits Backwards Total (0-4), Months in Reverse Order (0/1)] were taken from SCAT5 data.</p> <p><b>Outcome Measures:</b> Factor models identified through exploratory factor analysis (EFA) with and without oblique varimax rotation. Items with factor loadings ≥ 0.30 were retained in the factor model.</p> <p><b>Main Results:</b> Exploratory Factor Analysis performed with and without rotation produced similar 2-factor models with positive correlations. Factor 1 (Verbal Recall) consisted of the Immediate Memory and Delayed Recall items and Factor 2 (Working Memory) included the Orientation, Digits Backwards, and Months in Reverse Order items.</p>
