"Purpose: The purpose of this study was to collect normative data, evaluate concurrent validity, and examine reliability for the ImPACT Pediatric and ImPACT Quick Test-Pediatric Version. This study also explored the factors of age and sex for performance differences. Methods: A total of 202 youth athletes, 6 to 11 years of age volunteered to participate in this study. All athletes completed both the ImPACT Pediatric and ImPACT QT-PV during a testing session. The assessments were administered back-to-back, alternately. For the reliability portion of the study, 38 youth were administered the same assessments in a second testing session 1 week following the first testing session. Results: The ImPACT QT-PV constructs were dissimilar to the ImPACT Pediatric constructs, deeming it an invalid youth concussion assessment in its current form. Neither assessment demonstrated acceptable test-retest reliability. Age was found to affect performance scores on the ImPACT Pediatric, however only one difference was found based on sex within the ImPACT Pediatric. Conclusions: Further examination and revision of the ImPACT QT-PV should be conducted before its release for public use. Additionally, the ImPACT Pediatric and ImPACT QT-PV should be investigated for factors leading to instability of measurement over time. Cognitive performance on ImPACT Pediatric revealed an association between increasing age and better performance, however males and females demonstrated little difference in performance scores overall."--Page ii.
