Psychometric Properties and Reference Values for the ImPACT Neurocognitive Test Battery in a Sample of Elite Youth Ice Hockey Players

Show Summary Details

Preview

This cross-sectional study aimed to determine psychometric properties and reference values for ImPACT in a sample of 704 elite ice hockey players aged 13–17. Baseline ImPACT tests were completed at the beginning of the 2011–2012 season. Players aged 16–17 had better visual motor processing speed, adjusted R2 = .0522, F(2, 45) = 10.79, β = 2.87, p < .001, and impulse control, adjusted R = .0185, F(2,45) = 7.46, β = −1.35, p = .001, than younger players, and girls had greater total symptom ratings than boys (z = −3.47, p = .0005). There were no other sex- or age-related differences in neurocognitive performance, and no effect of previous concussion on ImPACT scores. Reference values with cut-off scores are presented.
