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 University of Minnesota Press published a new version of the MMPI-2, the MMPI-2 Restructured Form (MMPI-2-RF), in 2008. [31] The MMPI-2-RF builds on the Restructured Clinical (RC) scales developed in 2003, [ 9 ] and subsequently subjected to extensive research, [ 32 ] with an overriding goal of improved discriminant validity , or the ...
The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a self-reported personality test which is the most widely used psychological assessment measure in research to detect malingered PTSD, typically by comparing genuine PTSD patients with individuals trained and instructed to fabricate PTSD on the MMPI-2. [23] Numerous studies using the ...
These versions were evaluated using several criteria, such as internal consistency of the scales (or how much the items in one scale correlate with each other). The ability to fake good or bad while taking the test was also evaluated using a sample of college students that were given different instructions on how to answer the test. [3]
Most self-report inventories are brief and can be taken or administered within five to 15 minutes, although some, such as the Minnesota Multiphasic Personality Inventory (MMPI), can take several hours to fully complete. [2] They are popular because they can be inexpensive to give and to score, and their scores can often show good reliability. [3]
The University of Minnesota Press published a new version of the MMPI-2, the MMPI-2 Restructured Form (MMPI-2-RF), in 2008. [4] The MMPI-2-RF builds on the Restructured Clinical (RC) Scales developed in 2003, [ 1 ] with an overriding goal of improved discriminant validity , or the ability of the test to reliably differentiate between clinical ...
The Personality Assessment Inventory has validity scales to measure inconsistency (the degree to which respondents answer similar questions in the same way), infrequency (the degree to which respondents rate extremely bizarre or unusual statements as true), positive impression (the degree to which respondents describe themselves in a positive ...
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.
