Concussion in Motor Vehicle Accidents: The Concussion Identification Index

Concussion in Motor Vehicle Accidents: The Concussion Identification Index

The primary goal of this study is to provide clinicians with a brief, patient self-administer instrument yielding a single composite score that reliably correlates with objective findings on standardized neurocognitive assessment for concussion.

This Phase 2 study, Concussion in Motor Vehicle Accidents - The Concussion Identification Index (CIDI), focuses on the psychometric properties of the relationship between acute injury events, i.e. head impact, loss of consciousness (LOC), and post-traumatic amnesia (PTA), commonly reported post-crash signs and symptoms, and neurocognitive outcomes.

Cohort 1 is the validation group and will be used to confirm the optimal cut-off score of the Concussion Identification Index (CIDI) with the score on the ImPACT.

Cohort 2 is the cross-validation group.

Inclusion Criteria:
