Fake Bad Scale Discredited Once AgainFake Bad Scale Discredited Once Again
I recently read a new book entitled “MMPI-II Assessing Personality and Psychopathology (4th Edition) by Dr. John R. Graham. Dr. Graham played a major role in the development of the MMPI-II and is currently a professor of psychology at Kent State University.
In this text, Dr. Graham reviews the Fake Bad Scale developed by Paul Lees-Haley. Readers of this blog are familiar with other studies attacking the validity of this scale.
In this text, Dr. Graham writes, “Published research with the FBS does not support its validity for its intended purpose.” “A meta-analysis of MMPI-II malingering studies (Rogers et al., 2003) revealed that the FBS has been quite ineffective in identifying malingerers and, in fact, had the worst validity for this purpose of all of the MMPI-II scales included in the meta-analysis. It is this author’s recommendation that the FBS not be used to identify malingering of psychopathology on the MMPI-II.”
This book is another weapon in the arsenal to discredit the use of the FBS in neuro litigation.
