2. Millon’s Subtypes

Theodore Millon, an American psychologist, studied many personality disorders and was the founding editor of the Journal of Personality Disorders. He believed there are variants to all personality disorders and that by recognizing the differences, experts could reach a better understanding of each. He classified HPD into six different subtypes with varying definitions for each one. Millon’s subtypes of HPD are appeasing, vivacious, tempestuous, disingenuous, theatrical, and infantile.
