Neuropsychological test performance of Hawai'i high school athletes: Hawai'i ImPACT normative data.
OBJECTIVE
Establishing normative data of the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) performance of high school athletes in Hawai'i.


METHODS
Pre-season ImPACT testing was performed on 751 participants in football, baseball, basketball, soccer, volleyball, softball, and track from 4 Oahu public high schools. The ImPACT composite scores included measures of Verbal Memory, Visual Memory Processing Speed, and Reaction Time. The descriptive statistical data collected were the group means, standard deviations, standard errors of measurement, distribution of scores and percentile ranks of (1) 262 boys ages 13 to 15; (2) 297 boys ages 16 to 18; and (3) 192 girls ages 13 to 18.


RESULTS
The means and standard deviations of the 4 ImPACT composite scores for the 751 student-athletes in Hawai'i were similar to the ImPACT scores obtained from a master database of ImPACT test results. Although differences between the Hawai'i and mainland data were nonsignificant, there appeared to be a trend revealing somewhat lower scores in the Hawai'i sample of athletes.


CONCLUSIONS
The similarity in ImPACT test performance of Hawai'i high school athletes as compared to the mainland normative data provides support for the applicability of this computerized neuropsychological battery in Hawai'i. However in view of a trend reflecting slightly lower ImPACT scores among Hawai'i participants, the use of the normative data produced by this study may be desirable in assessing Hawai'i high school athletes.
