Classification
Supplemental: Sport-Related Concussion (SRC) Acute (time of injury until 72 hours) and Traumatic Brain Injury (TBI)
 
Exploratory: Sport-Related Concussion (SRC) Subacute (after 72 hours to 3 months)
Short Description of Instrument

Sport-Related Concussion-Specific:
Advantages/Limitations: It has been used by the TBI Model Systems project. Basic screen for exposure but not a diagnostic instrument nor a quantifiable instrument.
Psychometric Properties
These items were based on items in population-based surveys, including the Behavioral Risk Factor Surveillance System and the National Household Survey on Drug Abuse. The items are intended to provide a preliminary indication of problematic substance use. See recommendations of the Substance Use Disorders Work Group for a more complete evaluation of substance use disorders.
Scoring
The frequency of drug use, drinks/week, and binges/month can be determined. A dichotomous variable can be derived to indicate presence of "Problem Use" (use of any illicit drugs, binge drinking, or excessive drinking per the Dietary Guidelines for Americans).
