Summary
This summary is machine-generated.

Computer-based concussion tests show low to moderate reliability. These neurocognitive assessments are crucial but should be part of a broader concussion evaluation strategy.

Area of Science:

  • Neuroscience
  • Sports Medicine
  • Clinical Psychology

Background:

  • Computer-based neurocognitive assessment programs are widely used for concussion diagnosis and management.
  • Clinician adoption is often based on developer-provided test-retest reliability data.

Purpose of the Study:

  • To evaluate the test-retest reliability of three commercial computer-based neurocognitive assessments.
  • Assessments were examined within clinically relevant time frames.

Main Methods:

  • A repeated-measures design was employed in a research laboratory setting.
  • 118 healthy student volunteers completed ImPACT, Concussion Sentinel, and Headminder Concussion Resolution Index tests at baseline, day 45, and day 50.
  • The Green Memory and Concentration Test assessed participant effort; intraclass correlation coefficients estimated reliability.

Main Results:

  • Test-retest reliability coefficients (intraclass correlation coefficients) ranged from low to moderate across all three programs.
  • Reliability estimates between baseline and day 45 varied: ImPACT (.15–.39), Concussion Sentinel (.23–.65), and Concussion Resolution Index (.15–.66).
  • Reliability estimates between day 45 and day 50 also showed low to moderate coefficients, with all participants demonstrating high effort.

Conclusions:

  • Contemporary computer-based concussion assessment tools exhibit low to moderate test-retest reliability.
  • Findings were not attributable to poor effort or other performance factors.
  • Neurocognitive evaluation remains a vital component of comprehensive concussion assessment, prioritizing scores with higher reliability.
