The MCMI-III, or Millon Clinical Multiaxial Inventory III, is normed off of a clinical population and utilizes a standardization method of testing. This method ensures that the administration, scoring, and interpretation of results are consistent and reliable across different administrations.
To achieve this, the test is standardized on a sample that is representative of individuals with psychological disorders, typically using the mean and other statistical methods to create norms for comparison.
