Abstract

Objective To determine the association between performance on reaction time assessments using a computerized task and paper/pencil task.

Design Cohort

Setting Premiere league football clubs based in Lusaka, Zambia

Participants Male football athletes (age 26.8 ± 3.2years)

Interventions (or Assessment of Risk Factors) The ImPACT Quick Test (QT) neurocognitive assessment administered on an Apple iPad and booklet form of the King-Devick (KD) rapid reading assessment, completed during preseason.

Outcome Measures Outcome measures were median (Md) time to complete reaction time subtests on the ImPACT QT and cumulative KD assessment, in seconds.

Main Results After removing outliers, 78 football athletes completed the KD Test in Md=55.28 (IQR=48.8,65.75) seconds. Athletes scored a Md=19.12 (IQR=18.6,19.6) on the ImPACT QT’s Attention Tracker and Md=8.54 (IQR=7.2,9.7) on Motor Speed composites. Separate Spearman’s correlations revealed no significant associations between the time to complete the KD Test and the average time correct on the three Attention Tracker subtests: rectangular (rs =.19, p=.10) figure eight (rs = .15, p=.20), or complex (rs =.11, p=.33). There was a positive correlation between time to complete the KD Test and average time to complete each tap of the reverse counting task (rs =.38, p<.001). There were negative correlations between the KD Test and Attention Tracker (rs =-.28, p=.014) and Motor Speed (rs =-.33, p<.004) composites.

Conclusions These data add cultural diversity and African representation. While the ImPACT QT computerized reaction time task of counting is associated with performance on KD, these measures share only a small amount of variance, and appear to measure different constructs.
