Malingerer Test Roils

'Fake Bad Scale'
Bars Real Victims,
Its Critics Contend

A test designed to expose fakers is roiling the field of personal-
Proponents hail the true-
Use of the scale surged last year after publishers of one of the world's most venerable personality tests, the Minnesota Multiphasic Personality Inventory, endorsed the Fake Bad Scale and made it an official subset of the MMPI. According to a survey by St. Louis University, the Fake Bad Scale has been used by 75% of neuropsychologists, who regularly appear in court as expert witnesses.
But now some psychologists say the test is branding as liars too many people who have genuine symptoms. Some say it discriminates against women, too. In May, an American Psychological Association panel said there appeared to be a lack of good research supporting the test.
In two Florida court cases last year, state judges, before allowing the test to be cited, held special hearings on whether it was valid enough to be used as courtroom evidence. Both judges ended up barring it.
"Virtually everyone is a malingerer according to this scale," says a leading critic, James Butcher, a retired University of Minnesota psychologist who has published research faulting the Fake Bad Scale. "This is great for insurance companies, but not great for people."
The test asks a person to answer true or false to 43 statements, such as "My sleep
is fitful and disturbed" and "I have nightmares every few nights." Someone who suffers
from, say, post-
Other test statements are "I have very few headaches" and "I have few or no pains." These are false, someone who has chronic headaches would say. Again, those replies would incur two more points toward a possible assessment as a malingerer.
About a third of the questions relate to physical symptoms; there are questions about stress, sleep disturbance, and low energy. There is also a batch of questions related to denial of bad behavior. For instance, those who answer false to "I do not always tell the truth" get a point toward malingering.
Measuring Process

He tested responses to the 43 questions on three groups. One was personal-
The known fakers averaged a score of 27.6 on the Fake Bad Scale; those who had been
instructed to try to fake emotional distress averaged 25; and the truly injured litigants
averaged only 15.7, Dr. Lees-
He also compared the scores with those of two large groups who had taken the MMPI; both averaged below 20.
Dr. Lees-
It recently figured in the case of Steven Thompson, a onetime truck driver in Iraq
for the KBR unit of Halliburton Inc. He said he hadn't been able to hold a job since
returning to the U.S. in 2004. Two doctors concluded Mr. Thompson had "chronic" and
"fairly severe" post-
Mr. Thompson appealed to the U.S. Labor Department, which has jurisdiction in such cases. He testified that memories of attacks on his convoys, seeing dead bodies and smelling burning flesh led to nightmares and sleeping problems that left him too irritable and difficult to work with to hold a job.
A psychiatrist hired by the defense, John D. Griffith of Houston, concluded Mr. Thompson
was exaggerating his symptoms, and cited his score of 32 on the Fake Bad Scale. A
Labor Department administrative-
Dr. Griffith won't discuss the case but says the Fake Bad Scale is helpful in confirming
fakers, who he estimates make up 40% of personal-
In seven prior cases where Dr. Griffith worked for KBR or its insurer, he found five of the claimants to be malingering, court records show. Asked about the high percentage of Iraq truck drivers he found to be faking, he said: "When you come back to the States, you suddenly discover if you are sick you can make more money than if you were working."
Cutoff Score
Dr. Butcher and some other researchers published a report critical of the Fake Bad Scale in 2003. They looked at more than 20,000 people, including several thousand psychiatric inpatients, who had taken the MMPI and calculated their Fake Bad Scale scores by checking their replies to the scale's 43 questions.
More than 45% of psychiatric inpatients had Fake Bad Scale scores of 20 or more,
meaning they were possible fakers, under Dr. Lees-
The authors argued it was unlikely that so many psychiatric inpatients could or would have fooled doctors into diagnosing and admitting them to hospitals. It concluded that the Fake Bad Scale generated an "unacceptably high" rate of false verdicts of malingering, and also that it was biased against women.
Says Dr. Lees-
In 2006, the publishers of the Minnesota Multiphasic Personality Inventory took a look at the Fake Bad Scale. Those who take the MMPI receive scores on various categories, such as paranoia, depression and social introversion. The question was whether to make the Fake Bad Scale one of these scored categories as well.
The University of Minnesota Press convened a panel of eight experts and pointed to
two published reports for them to consider. One was a book chapter partly written
by Dr. Lees-
The review of existing research ended up looking at 19 studies, at least 10 of which
had been done by Dr. Lees-
Dr. Butcher, a member of the advisory panel, opposed adding scores of the Fake Bad Scale to the results that are reported when a person takes the Minnesota Multiphasic Personality Inventory. Six of the eight panelists approved, although they differed on how the test should be used and what cutoff scores were appropriate. The University of Minnesota Press then did make the Fake Bad Scale a subset of the MMPI.
A few months later, the American Psychological Association's committee on disabilities protested to the publisher that it had acted prematurely. The APA committee later said it hadn't evaluated the test itself, but noted that the test was controversial and said: "Any test that over predicts malingering in persons with disabilities may result in their being denied necessary and due compensation, benefits or treatment." The committee asked the MMPI publisher to have the Fake Bad Scale reviewed by a group at the University of Nebraska that specializes in evaluating psychological tests.
The University of Minnesota Press didn't respond to a call. But in a letter to Ms. Sims, the Florida plaintiffs' lawyer, a lawyer for the university said it "recognizes that the FBS is the subject of significant debate in the academic and professional community.... The University believes that the process leading up to the FBS' release was sound."
Courtroom Test
The experts' disagreement spilled over into the courtroom in a case brought against
a Florida gasoline carrier, Strawberry Petroleum Inc. Lloyd Davidson was sitting
at a stoplight in May 2004 when his pickup was rear-
A psychologist hired by the defense said in a deposition there was reason to believe Mr. Davidson was faking. The witness cited his "very high" score of 31 on the Fake Bad Scale.
Before the expert could testify at the trial, held in Hillsborough County Circuit Court, the plaintiffs moved for a hearing on the scientific validity of the Fake Bad Scale. Judge Sam Pendino ruled in June that "there is a genuine controversy surrounding use of this test" and "no hard medical science to support the use of this scale to predict truthfulness." He said that drawing conclusions from a test that gives points for malingering when a plaintiff gives honest answers to questions based on actual injuries "has no place in this courtroom."
In January, a jury determined that Mr. Davidson had suffered a permanent injury from the crash and awarded him $1.4 million from the gasoline carrier.
