The MCMI (Millon, 1983a, 1987, 1944, 1997a) was developed to operationalize
Millon's (1969/1983b) model of psychopathology and has been revised 2 time
s over the past 20 years to keep pace with changes in theory as well as the
Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American P
sychiatric Association, 1994). Since its introduction in 1977, it has becom
e one of the most widely used and researched clinical assessment instrument
s in history, generating over 500 articles and 6 books. It has been transla
ted into several languages and is being used in cross-cultural research. Th
is article presents a historical overview of the measure and summarizes its
current status in the literature. I highlight Millon's original vision for
the test, changes that have been made, and its strengths and limitations.-
Future refine-ment of the MCMI is already in the planning stages and includ
es trait subscales for the personality disorders and linking codetypes to t
heory-derived interventions.
