Abstract | The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a popular assessment tool used for the psychosocial assessment of personal injury litigants. However, there are inherent structural problems found in the MMPI-2 that question the utility of this test. In 2006, Goh restructured the MMPI-2 at the item level in order to provide a more accurate and reliable assessment device. Using a large sample of personal injury litigants, Goh rebuilt the MMPI-2’s scoring and analysis system specifically for the psychosocial assessment of personal injury litigants. Called the Minnesota Multiphasic Personality Inventory-2 for use with personal injury litigants (MMPI-2-PI), the development of the MMPI-2-PI used contemporary methods with the goal of enhancing internal consistency and eliminating item overlap. A unique feature of the MMPI-2-PI were items that were weighted according to the relevance of the constructs they measured which resulted in independently weighted scales and subscales. Since Goh’s initial restructuring of the MMPI-2, Ben-Porath and Tellegen (2008) developed the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) also using contemporary methods to restructure the MMPI-2. Published in 2008, the MMPI-2-RF was developed as an alternative version of the MMPI-2 for routine clinical psychosocial evaluation. While the MMPI-2-PI appeared to be a promising new approach for assessing personal injury litigants, it was still in its infancy. As such, the goals of this dissertation were to examine the Incremental validity and clinical utility of the MMPI-2-PI by comparing it to the more traditional MMPI-2 and more contemporary MMPI-2-RF. Using a sample of 2,989 personal injury litigants, analysis of the MMPI-2-PI included two comparisons: one with the MMPI-2-PI and MMPI-2; and the second between the MMPI-2-PI and the MMPI-2-RF. Comparisons between the MMPI-2-PI and the MMPI-2 demonstrated improved Incremental validity and |
