Is the MCMI-III Corrections Report based on empirical data?
Parts of the report are based on empirical data, and parts are based on Dr. Millon’s theories and clinical insights. For example, each inmate is classified as “High,” “Moderate,” or “Low” in terms of his or her probable need for mental health intervention, for substance abuse treatment, and for anger management services. These classifications are based on prediction models developed as part of a large-scale research project involving over 10,000 inmates who completed the MCMI-III test at intake. (This research is described in more detail below.) Other behavioral and clinical predictions and inferences contained in the report, such as an analysis of the inmate’s personality patterns and of treatment considerations, are theoretically driven.
