Usually, anything above a 75 T-Score denotes a very high ranking on that scale, that is, within the top 1% of the population. T-Scores are not percentages, but may be translated into percentages. What you will be paying attention to are the T-Scores, not the Raw Scores, unless otherwise specified. The MMPI-2 produces T-Scores and Raw Scores. The scales are typically referred to by their number, with Si being numbered as 0, as stated above and also shown in the image below. Once validity of the answers (link goes to a search of scientific articles on the subject) is established, a profile is created employing the 10 Clinical Scales:Įach of these is in itself composed of various other sub-scales and has a further Obvious / Subtle division that is important. Using 567 true or false questions, rates the tester on 130 categories (validity scales included). court cases of many kinds and why it is also used for employment hiring and promoting, from emergency services to police to military personnel, and in the private sector too.

The MMPI-2 was published in 1989, with a larger and more diverse sample having been used as calibration, including not only individuals from the general population and individuals asked to pretend to be good or bad or to have a specific disorder but also taking into account the findings of many scientific studies that led to the inclusion of subscales and the supplementary scales. Published in 1940, the MMPI was the first comprehensive test that was data-driven, that largely did away with theory, and it was first calibrated by asking inpatient and outpatient individuals of psychiatric hospitals with well-known conditions to answer the test as they would if honest. The Minnesota Multiphasic Personality Inventory (MMPI-2) is the most used personality test in clinical settings in the United States it is also the only personality test the results of which are recognized and used by that country's courts of law. Both the long and short forms of the MMPI-2 but not the MMPI-A commonly given to adolescents are available through this link.
