Area of Science:

  • Neuroscience
  • Sports Medicine
  • Psychology

Background:

  • Multivariate base rates (MBRs) of low scores in healthy populations are established using the Immediate Postconcussion and Cognitive Testing (ImPACT) tool.
  • The utility of MBRs of reliable change in differentiating between concussed and healthy individuals remains largely unexamined.

Purpose of the Study:

  • To investigate the discriminative ability of MBRs of reliable change in identifying individuals with concussion.
  • To assess the incremental utility of MBRs of reliable change when combined with posttest probabilities using Bayes' Theorem.

Main Methods:

  • Archival review of data from 129 healthy individuals and 81 individuals diagnosed with concussion.
  • Examination of MBRs of reliable change scores at various cutoffs and frequencies.
  • Application of Bayes' Theorem to compute posttest probabilities.

Main Results:

  • Composite scores demonstrated small to medium effect sizes in differentiating between the concussion and healthy groups.
  • MBRs of reliable change scores on ImPACT alone offered limited discriminative power.
  • Incorporating MBRs of reliable change into Bayes' Theorem calculations provided incremental gains in diagnostic accuracy under specific conditions.

Conclusions:

  • MBRs of reliable change on ImPACT have limited standalone utility for concussion diagnosis.
  • The integration of MBRs of reliable change with probabilistic models like Bayes' Theorem can enhance diagnostic capabilities for concussion.
