Description of Measure
Descriptive items that assess how many times, if any, the subject has had a head injury that resulted in the loss of consciousness. These items were developed for the study based on a consultation with two neuropsychologists (Lisa Marrow, University of Pittsburgh School of Medicine and Charles Nelson, Univ of Minnesota). These items establish the presence of brain injury (e.g. how many times the subject had a head injury that resulted in the loss of consciousness) and the extent of the injury (e.g. presence of seizures and medical treatment).
We compute the following:
- A marker for the presence of a head injury which caused unconsciousness or needed medical attention [S#HEADIN]
The following individual item is also available:
- Number of head injuries in the recall period where lost consciousness or needed medical treatment [S#HeadInj_HeadN]
For a monthly plotting of head injuries, please consult the Head Injury Calendar codebook section.
