Defense attorneys often claim that people who suffer invisible injuries in collisions, such as plaintiffs who suffer traumatic brain injuries, are faking or exaggerating their life-changing symptoms. As a result, defense attorneys retain and pay experts to evaluate the injured person via a multitude of psychological tests. Those well-paid expert witnesses then typically testify at trial that the plaintiff's symptoms fail to comport with the injury.
One controversial test, the Fake Bad Scale (FBS), claims to identify malingerers (the term used for people who supposedly fabricate or exaggerate their symptoms of mental or physical disorders for secondary gain, including financial compensation). Unfortunately, the FBS is now a component of the Minnesota Multiphasic Personality Inventory (MMPI) personality inventories. Plaintiff's personal injury attorneys, like me, despise the FBS, as it misjudges legitimate health issues and almost always over-reports malingering.
The issue of real, yet, invisible injuries versus the FBS recently intersected in a case in the Eastern District of Pennsylvania: Amadio v. Glenn, 2011 U.S. Dist Lexis 9549 (February 2011). There, plaintiff claimed that he suffered worsening brain damage, which originally resulted from a collision six years earlier, when defendant-driver suddenly struck his car. Plaintiff's attorney and the defendants' attorney requested that experts evaluate the nature and cause of the collision as well as plaintiff's present injuries.
Defendants' experts subjected plaintiff to the MMPI- 2 personality inventory. It's not surprising that the defendants' paid experts later opined that the plaintiff's MMPI-2 results indicated "over-reporting and exaggeration of psychopathology," "extreme levels of exaggeration," "responding bias," and that "[plaintiff] skewed his responses toward greater psychopathology." 2011 U.S. Dist Lexis 9549, *11.
Prior to the commencement of trial, plaintiff filed a motion to preclude testimony related to the results of the MMPI-2 test. Specifically, plaintiff challenged the reliability of defendants' experts' methodology and the fit of their opinions to the evidence, arguing the experts' evaluation was flawed because MMPI-2 (1) cannot be validly used or interpreted in patients who are known to be brain damaged, and (2) the FBS sub-scale is scientifically invalid as it overestimates malingering.
Although the Court agreed with defendants that in general the interpretation of certain test results should not be precluded, but should instead be subjected to cross-examination, plaintiff's argument that the MMPI-2 test should not be administered to people with known brain damage caused the Court to pause. (Unfortunately, the Court did not address the plaintiff's contention that the FBS is scientifically invalid.)
In finding for the plaintiff, the Court stated the experts failed to show, pursuant to Federal Rule of Evidence 702, that (a) their opinion based on the MMPI-2 test consisted of a testable hypothesis with regard to brain damaged victims, (b) the MMPI-2 had been subjected to peer review on the subject of brain damaged people, (c) there existed standards controlling the technique's operation for brain damaged individuals, or most particularly and importantly (d) the method has been generally accepted for use on those who are brain damaged.
