IntroductionIt can be said that there are many tests that have been created by psychologists around the world, but among all these tests, how many are as unique as the Millon? Through rigorous research and reading, I selected the Millon Clinical Multiaxial Inventory-III test. The Millon Multiaxial Clinical 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, embodies several innovative ideas in personality assessment and psychopathology (Grove, 2003). Moving between 3rd and 4th edition was a unique opportunity and an incredible 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 previously stated, the name of the test selected is the Millon Clinical Multiaxial Inventory-III. This test is authored by Theodore Millon, PhD, DsC, with Carrie Millon, PhD, Roger Davis, PhD, and Seth Grossman, PsyD (Millon, Millon, Davis & Grossman, 2006). This current edition added the new Grossman facet scales for the Clinical Personality Patterns and Severe Personality Pathology scales (Millon, et al., 2006).
