IntroductionIt can be said that there are numerous tests created by psychologists all over the world, but of all these tests, how many are as unique as the Millon? Through rigorous research and reading I selected the Millon Clinical Multiaxis Inventory-III test. The Millon Clinical Multiaxical Inventory (3rd: MCMI-III) is a widely used psychological assessment of clinical and personality disorders (Grove, WM, 2009). This test, now in its third edition, has embodied several innovative ideas in the assessment of personality and psychopathology (Grove, 2003). Going from the third to the fourth edition was a once-in-a-lifetime opportunity and an amazing learning experience. Through analysis of the MCMI-III manual and other sources, this test can be explained and examined in depth helping to better understand this influential psychological assessment tool. General Information As stated previously, the name of the selected test is Millon Clinical Multiaxis Inventory-III. This test was written by Theodore Millon, PhD, DsC, with Carrie Millon, PhD, Roger Davis, PhD, and Seth Grossman, PsyD (Millon, Millon, Davis & Grossman, 2006). This current edition has added new Grossman facet scales for the Clinical Personality Patterns and Severe Personality Pathology scales (Millon, et al., 2006).
