The Fake Bad Scale (FBS) Paul R. Lees-Haley, Ph.D., ABPP The Fake Bad Scale (FBS) was designed to assist in the detection of personal injury malingering with the MMPI-2 (Lees-Haley, English, & Glenn, 1991). The expression “fake bad” was used because historically this phrase had been applied to invalid response sets on the MMPI. In hindsight, the FBS appears to be better thought of as in an indication of an invalid response style, for example, in somatic injury cases, including brain injury claims, without necessarily assuming we always know why the patient is exaggerating or presenting an invalid self portrayal. Although originally intended for emotional distress injuries, the practice from which the scale was originally derived included many individuals with neurological, chronic pain, orthopedic and other physical injury claims, and a steadily growing body of peer-reviewed empirical research has indicated that the FBS is useful in the detection of somatic malingering (e.g., cases reporting physical injuries or pain, including neuropsychological cases). The relevance of the FBS to somatic issues apparently was first reported by Putnam and Adams in 1995 at the 30th Annual MMPI International Symposium in St. Petersburg, Florida. Later Larrabee (1997) suggested that “somatic malingering should be considered whenever elevations on scales 1 and 3 exceed T80, accompanied by a significant elevation on the FBS) (p. 203). Recent research has also again successfully applied the FBS to emotional distress/psychological trauma cases (e.g., see Greiffenstein, Baker, Axelrod, Peck & Gervais, 2004). Answer Key: Following are the MMPI-2 items and scored direction of answering for the Fake Bad Scale (FBS): Add one point if marked True: 11, 18, 28, 30, 31, 39, 40, 44, 59, 111, 252, 274, 325, 339, 464, 469, 505, 506 Add one point if marked False: 12, 41, 57, 58, 81, 110, 117, 152, 164, 176, 224, 227, 248, 249, 250, 255, 264, 284, 362, 373, 374, 419, 433, 496, 561 Note : Two methods for pro-rating FBS scores from incomplete and 370-item protocols have been developed. They produce essentially identical results: (1) Fox, D.D. (2004, November). Prorating the Fake Bad Scale of the MMPI-2: Empirically Derived Equation s.
