The Lees-Haley Fake Bad Scale (FBS) or MMPI Symptom Validity Scale is a set of 43 items in the Minnesota Multiphasic Personality Inventory (MMPI), selected by Paul R. Lees-Haley in 1991 to detect malingering for the forensic evaluation of personal injury claimants. [1]
The original MMPI was developed on a scale-by-scale basis in the late 1930s and early 1940s. [16] Hathaway and McKinley used an empirical [criterion] keying approach, with clinical scales derived by selecting items that were endorsed by patients known to have been diagnosed with certain pathologies.
The original MMPI was replaced by an updated version, the MMPI-2, in 1989. A version for adolescents, the MMPI-A, was published in 1992. An alternative version of the test, the MMPI-2 Restructured Form (MMPI-2-RF), retains some aspects of the traditional MMPI assessment strategy, but adopts a different theoretical approach to personality test ...
The validity scales measure the respondent's overall approach to the test, including faking good or bad, exaggeration, defensiveness, carelessness, or random responding. Inconsistency (ICN) is the degree to which respondents answer similar questions in different ways.
A self-report inventory is a type of psychological test in which a person fills out a survey or questionnaire with or without the help of an investigator. [1] Self-report inventories often ask direct questions about personal interests, values, symptoms, behaviors, and traits or personality types.
The usefulness of the currently-existing validity scales is sometimes questioned. One theory is that subjects in tests of validity scales are given instructions (e.g. to fake the best impression of themselves or to fake an emotionally disturbed person) that virtually guarantee the detection of faking.
In testing validity of the IPI-2, internal consistency was measured using Cronbach's Alpha (overall=0.52). Significant correlations (<.05) were analyzed between IPI-2 scales and MMPI-2-RF and the PAI (Personality Assessment Inventory). Results are combined with Field Training Officer (FTO) Predictions, in order to provide a more complete analysis.
With graduate student Paul Meehl, Hathaway developed three validity scales embedded within the MMPI: the L, or lie, scale indicates when a client is "faking good"; the F, or infrequency, scale indicates when a client is "faking bad"; the K, defensiveness scale identifies individuals in denial about their behaviors and symptoms.
