The MCMI-IV offers updated norms that are based on a clinical adult population, a new scale, DSM-5® and ICD-10-CM alignment, updated narrative content and a new and deeper therapeutic focus.  The brevity of the MCMI-IV allows clinicians to maintain an efficient and productive clinical practice.

Users & Applications

Insights provided in the MCMI-IV help to guide clinicians in identifying deeper pervasive clinical issues, so that they are better equipped to make reliable diagnostic and treatment decisions.

The assessment, used in multiple settings including clinical and counseling, medical, government, and forensic, can help:

  • Identify deep, pervasive clinical issues
  • Facilitate treatment decisions
  • Assess disorders based on DSM-5® and ICD-10 classification systems

Features & Benefits

  • Full normative update, more closely representing the current clinical adult population
  • New Turbulent scale, providing deeper understanding of those patients presenting with this unbridled personality type
  • New and updated test items characterizing the evolution of Dr. Millon’s personality theory, refreshed to increase clarity and clinical relevance
  • New and improved narrative content that better integrates results with therapeutic practice and links to personalized treatment
  • Updated Grossman Facet Scales
  • Aligns with DSM-5; includes ICD-10 code sets
  • New option to present scale scores using scale abbreviations
  • Brevity, allowing clinicians to maintain an efficient and productive clinical practice
  • 5th Grade reading level
  • Seven new Noteworthy Response categories
  • New digital manual in Q-global Resource Library

Psychometric Information

The extensive normative sample for the MCMI-IV consists of a nationally representative sample of 1,547 males and females with a wide variety of diagnoses. This combined-gender sample includes adult patients seen in a wide array of settings, such as clinics, independent practices, mental health centers, residential facilities, and hospitals.

Turbulent Scale—New!

MCMI-IV Scale 4B: Ebullient–Exuberant–Turbulent Spectrum

The Turbulent scale on the MCMI-IV provides clinicians with a deeper understanding of adult patients experiencing abnormal personality traits, such as a lost sense of reality or unwavering optimism. “Turbulent” refers to the more severe (disorder) end of the personality functioning spectrum.

Dr. Millon conceptualized the Ebullient–Exuberant–Turbulent personality pattern as typically energetic and buoyant in manner and prone to vigorous pursuits of happiness.

The high energy and generally positive attitude of moderated variants of this pattern can show considerable characterologic strengths. Patients with less integrated variations of this pattern may be prone to scatteredness, overstimulation, overanimation, and an inability to maintain balance within their environment which can adversely affect their relationships with others.


The MCMI®-IV overtly conceptualizes personality patterns on a new continuum, or spectrum, ranging from adaptive to maladaptive levels of functioning. The MCMI-IV personality patterns, or scale spectrums, capture the patient’s broad range of personality by way of three levels of personality functioning:

  • Normal Style: Generally adaptive personality patterns
  • Abnormal Traits/Type: Moderately maladaptive personality attributes
  • Clinical Disorder: Likelihood of greater personality dysfunction

For example: The CENarc spectrum
Normal Style: Confident
Abnormal Traits/Style: Egotistic
Clinical Disorder: Narcissistic
