Validity as Applied to Neuropsychological Assessment
The concept of test validity basically corresponds to the question of whether a test or an assessment procedure supplies the kind of information needed for a particular interpretation. This issue is very important because the test scores in and of themselves are meaningless unless they refer to a defined realm of observable phenomena. In clinical psychology, the consequence of interest may be a particular personality style or behavioral disorder. For clinical neuropsychology, the consequence of interest may range from whether brain impairment exists to the implications of the test results for adaptive behavior. Before particular issues that affect the validity of neuropsychological tests are described, general applicable concepts of validity and threats to validity are reviewed.
