I. Background

Premier personality psychologist, Theodore Millon has been described as the “primary architect for the personality disorders” that have appeared in every Diagnostic and Statistical Manual (DSM) edition since the third (Choca & Grossman, 2014, p. 541).

Millon’s biosocial model of personality also helped the American Psychiatric Association remain steadfast to its multi-axial system of diagnosis, upon which personality is Axis II (Millon & Grossman, 2015).

Million was also the architect of the Millon Clinical Multiaxial Inventory (MCMI).

Millon’s personality theory is evolutionary and biosocial, and the theorist was undoubtedly influenced by the evolutionary biology theories of Charles Darwin (American Psychological Association, 2009).

A. Historical Overview

Millon was born in Manhattan in 1928, and was an only child. He died in 2014 (“Theodore Millon – obituary,” 2014).

He began studying psychology in undergraduate school and showed an early predilection towards the understanding of abnormal psychology and personality disorders (“Theodore Millon—obituary,” 2014).

Grossman was also dedicated to a “data-driven” model of personality, and he employed a deductive methodology of studying personality (Grossman, 2015, p. 437). These methods helped Millon develop personality inventories like the MCMI.

Grossman’s early research gave rise to both the biosocial and evolutionary approaches to personality disorders, which show how a person’s personality is a function of both biological factors but also environmental ones.

C. Key Concepts

The evolutionary principles guiding human personality development include the three primary aims: the existence aim, the adaptation aim, and the replication aim, with a fourth later added called the abstraction aim (Grossman, 2015).

There are several functional domains in which personality is manifest: expressive emotion, interpersonal conduct, cognitive style, and intrapsychic dynamics (Grossman, 2015). These domains are how personality may be assessed and classified.

The main structural domains of personality include self image, intrapsychic content, intrapsychic….....
