Using an aggregate baseline approach with the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) improves reliability for assessing athlete cognition. Adding a third baseline further enhances test-retest reliability for clinical use in sports concussion management.

Area of Science:

  • Neuroscience
  • Sports Medicine
  • Psychometrics

Background:

  • The Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) is widely used for athlete cognitive assessment.
  • Concerns exist regarding ImPACT's test-retest reliability in clinical settings, potentially leading to premature return-to-play decisions.
  • Previous research suggested improved reliability using a composite structure and aggregated baselines.

Purpose of the Study:

  • To confirm previous findings on the aggregate baseline approach for ImPACT reliability.
  • To investigate if a third baseline enhances ImPACT's test-retest reliability.

Main Methods:

  • Utilized data from 97 professional hockey players with at least 4 ImPACT baseline evaluations.
  • Employed linear regression to assess the predictive variance of the first three testing sessions on the fourth session.

Main Results:

  • The aggregate baseline approach significantly enhances the psychometric properties of ImPACT.
  • Most cognitive indices demonstrated adequate or superior test-retest reliability for clinical application.

Conclusions:

  • The aggregate baseline approach offers a modest clinical advantage with recent baselines and a substantial benefit over single-baseline methods.
  • Neuropsychologists are encouraged to adopt the aggregate baseline approach for precise quantification of cognitive changes post-sports concussion, pending broader sample validation.
