Millon Inventories

Personality dysfunction can be a root cause of common daily challenges individuals might be facing, such as significant relationship issues, financial stress, anxiety, and depression. If your client is encountering these frequent causes of psychological distress, there could be underlying personality issues that the Millon Inventories can help assess.

The Millon Inventories are based on Dr. Theodore Millon''s APA award-winning theory of personality. These comprehensive assessments provide a theoretical foundation to make reliable diagnostic and treatment decisions in a wide range of settings including clinical and counseling, school, medical, government, and forensic.

As the field of psychology changes, the Millon Inventories continue to adapt and evolve.

Benefits of using the Millon Inventories:

  • Both theoretically driven and empirically guided: The Millon inventories blend together both Dr. Millon's theory and sound empirical research to form a cohesive understanding of an individual's personality.
  • Closely correlated with the DSM®: A connection with the DSM® classification system of personality disorders increases their diagnostic utility and facilitates easy communication among practitioners.

As the need for efficient and accurate differential diagnosis of complex disorders grows, this feature has become increasingly valued.
  • Enable more effective treatment planning: Customized Interpretive Reports help bring critical concerns to light and provide a foundation upon which treatment plans can easily be developed.
