Concussion in Motor Vehicle Accidents: The Concussion Identification Index

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correlation - Concussion Identification Index score with ImPACT test score |  | Within 90 days of the accident | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient-completed one page questionnaire | The questionnaire is divided into two parts: The Injury Characteristics section: asks for a yes-no indication of whether 5 concussion-associated events/injuries occurred: striking the head, whiplash, loss of consciousness, being dazed, or having post-traumatic amnesia; and, whether or not the patient had already been given a diagnosis of concussion. The Concussive Symptoms section asks the patient to rate on a scale of 0-3 the presence and severity of 10 cognitive and emotional symptoms associated with a post-concussion diagnosis. The total numeric value for each patient is reported as an indexed score. | Within 90 days of the accident |
