The third edition of this popular test, the Millon Clinical Multiaxial Inventory (MCMI-III), has been published in 1996. With 175 items, it is much shorter and simpler to administer and to interpret than the MMPI-II. The MCMI-III diagnoses personality disorders and Axis I disorders but not other mental health problems. The inventory is based on Millon's suggested multiaxial model in which long-term characteristics and traits interact with clinical symptoms.
The questions in the MCMI-III reflect the diagnostic criteria of the DSM. Millon himself gives this example (Millon and Davis, Personality Disorders in Modern Life, 2000, pp. 83-84):
"... (T)he first criterion from the DSM-IV dependent personality disorder reads 'Has difficulty making everyday decisions without an excessive amount of advice and reassurance from others,' and its parallel MCMI-III item reads 'People can easily change my ideas, even if I thought my mind was made up.'"
The MCMI-III consists of 24 clinical scales and 3 modifier scales. The modifier scales serve to identify Disclosure (a tendency to hide a pathology or to exaggerate it), Desirability (a bias towards socially desirable responses), and Debasement (endorsing only responses that are highly suggestive of pathology). Next, the Clinical Personality Patterns (scales) which represent mild to moderate pathologies of personality, are: Schizoid, Avoidant, Depressive, Dependent, Histrionic, Narcissistic, Antisocial, Aggressive (Sadistic), Compulsive, Negativistic, and Masochistic. Millon considers only the Schizotypal, Borderline, and Paranoid to be severe personality pathologies and dedicates the next three scales to them.
The last ten scales are dedicated to Axis I and other clinical syndromes: Anxiety Disorder, Somatoform Disorder, Bipolar Manic Disorder, Dysthymic Disorder, Alcohol Dependence, Drug Dependence, Posttraumatic Stress, Thought Disorder, Major Depression, and Delusional Disorder.
Scoring is easy and runs from 0 to 115 per each scale, with 85 and above signifying a pathology. The configuration of the results of all 24 scales provides serious and reliable insights into the tested subject.
Critics of the MCMI-III point to its oversimplification of complex cognitive and emotional processes, its over-reliance on a model of human psychology and behavior that is far from proven and not in the mainstream (Millon's multiaxial model), and its susceptibility to bias in the interpretative phase.
