Validity of the Neuropsychological Test Battery

Principal Investigator: Dennis Zgaljardic, Ph.D.

Purpose of the Study: The Neuropsychological Assessment Battery (NAB; Stern & White, 2003) is a comprehensive neuropsychological test battery.  The NAB incorporates five tests of “daily living” as a means to assess skills that are “congruent with an analogous real-world behavior”.  The five measures include:

  • Driving Scenes (attention)
  • Daily Living Memory (memory)
  • Map Reading (spatial)
  • Bill Payment (language)
  • Judgment (executive)


The ecological validity of the NAB Daily Living Measures have not been assessed using a brain-injured population.  The purpose of the current study was to assess the relationship between the NAB daily living measures and the Mayo-Portland instrument (a well known rating instrument of functional status in individuals with disabilities) in patients with traumatic brain injury.
