Description of Measure
Four descriptive items regarding head injury 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), the age at which the injury occurred and the extent of the injury (e.g. presence of seizures and medical treatment).
Two computed variables are available:
- A marker for the presence of a head injury which caused unconsciousness or needed medical attention [s0headin]
- The earliest age at which loss of consciousness occurred [s0malc]
