Why
  1. The study's listed conditions name Brain Concussion, a narrower term within Brain Injuries, Traumatic.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study 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.

Read the 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.

Study population

Cohort 1 - Validation Group: Consecutive patients who presented for care between November 1, 2013 and December 31, 2014 at the MVA Center for Rehabilitation, a public health clinic in Springfield, MA which provides specialized outpatient auto accident treatment and rehabilitation

Cohort 2 - Cross Validation Group: Consecutive patients who presented for care between January 1, 2015 and June 30, 2016 at the MVA Center for Rehabilitation, a public health clinic in Springfield, MA

What researchers measure

Primary outcomes

  1. Correlation - Concussion Identification Index score with ImPACT test score

    Time frame: Within 90 days of the accident

Secondary outcomes

  1. 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.

    Time frame: Within 90 days of the accident

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 8, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
