Psychological tests are frequently used by forensic psychologists engaged in evaluations for family court matters. Since the recommendations that flow from such evaluations can have considerable influence on the disposition of such cases, it is crucial that any tests used by the forensic evaluator possess solid scientific reliability and validity.

This brief essay discusses these limitations and urges attorneys to vigorously challenge expert testimony based upon this flawed test.
