Williams, Arthur (2001). Psychometric concerns in
neuropsychological testing. Neuro Rehabilitation
16.

• Attempts to describe measurement and norming
  problems that both exist and are common among
  neuropsychological tests
• Shows the need for further development in
  neuropsychological testing.

3
Problems with Batteries

• Few batteries to show the ability of the test to
  distinguish between two or more diagnostic groups
  of concern
• Standardize flexible and fixed battery tests

4
Flexible Battery Problem

• Scores on flexible battery tests differentiate
• No group for comparison can exist
• No bell shaped curve
• Tests lack accuracy

5
Reliability

• Minimum reliability is 0.80
• Many do not give reliability
• Collecting new evidence is necessary

6
Problem Comparing Scores

• Comparing scores to means and standard deviations
  of normal samples
• Different scores from tests
• No normative sample

7
Critical Review

• Tests should be used with extreme caution
• Further research is needed
