AbstractThe Clinical Neurologic Assessment (CNA) Instrument (Crosby & Parsons, 1989) was developed to assess for subtle changes in the level of consciousness of traumatically brain injured individuals. The instrument has been refined from a 56-item tool to a nine-item tool. This research determined the reliability and validity of the refined nine-item CNA instruments when used to assess brain injured elderly. Internal Consistency of the CNA using Cronbach' alpha demonstrated the total CNA estimated at .96. Concurrent validity of the CNA using Pearson's Product-Moment Correlation Coefficients was .94 for the CNA and the Glasgow Coma Scale (GCS) . The CNA proved to be a reliable and valid instrument for determining changes in the level of consciousness in the elderly brain injured patient.
