Lees-Haley Fake Bad Scale

The Lees-Haley False Bad Scale (FBS) or MMPI Symptom Validity Scale is a set of 43 items in the Minnesota Multiphasic Personality Inventory selected by Paul R. Lees-Haley on in 1991 to detect fake sickness for the evaluation of a private witch forensic. It was supported by the publisher of MMPI in 2006 and put in the key of official appraisal. A 2008 Wall Street Journal article notes that some psychologists argue that it is controversial because they feel that some individuals with legitimate injuries will be categorized as bad-tempered.

History

The items in FBS were selected by Lees-Haley based on the frequency difference between individual samples known as fake sick and individuals who were judged to have valid complaints and personal observations of the malingerers.

FBS is a generally accepted test of validity. For example, in a survey of the use of validity tests, Sharland and Gfeller (2007) found that FBS is the third most commonly used validity test by neuropsychologists. In a more recent study, Martin, Schroeder, and Odland (2015) found in a survey of common practitioners that FBS is the most widely used symptom validity test (SVT) for MMPI-2 and one of the two most widely used for MMPI-2 -RF.

Validity

FBS's largest meta-analysis comparing 1,615 assessed over-reporters for 2,049 normal patients and found an effect size of 0.94. The authors conclude that "the current literature supports the use of FBS in forensic settings " (p.a, 55).

An updated meta-analysis of data from 5,341 subjects published in 2010 further confirms these first findings. The authors conclude, "FBs-dependent practitioners can be reassured that extensive literature now strongly supports the application of FBS in the practice of forensic neuropsychology" (p.717).
