Millon® Clinical Multiaxial Inventory - IV (MCMI® - IV)

Clinical | Educational | Psychopathology | Clinical Diagnosis

Anchored in Dr Theodore Millon’s time-honoured personality theory, the Millon Clinical Multiaxial Inventory-IV (MCMI-IV) provides helpful clinical insights into a patient’s personality that allow clinicians to make reliable diagnostic-and treatment decisions.

The MCMI-IV offers updated norms that are based on a clinical adult population, a new scale,DSM-5 andICD-10-CMalignment, 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.

The MCMI-IV has the following benefits:

  • Full normative update, more closely representing the current clinical adult population
  • Supported by more than 35 years of research
  • New Turbulent scale, providing deeper understanding of those patients presenting with this unbridled personality type
  • New and updated test items characterising 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 personalised treatment
  • Updated Grossman Facet Scales

The MCMI-IV also introduces a Spectrum of Personality Patterns. The MCMI-IV overtly conceptualises 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


The MCMI-IV consists of a total of 25 scales providing insight into 15 personality disorders, 10 clinical syndromes and the Grossman Facet Scales. The following scales are included in the MCMI-IV:

The MCMI-IV can be used for the following purposes:

The MCMI-IV was specifically designed to facilitate the therapeutic plans of the clinician. The MCMI-IV enables the integration of test results with therapeutic practice. The improved Treatment Guide section of the interpretive report helps you make a connection with the patient right from the beginning.


The MCMI IV has following software reports available:

  • Profile Report: Provides a graphic representation of base rate scores for all scales including the Grossman Facet Scales. This report can help to quickly identify clients who may require more intensive evaluation.
  • Interpretive Report: Provides an in-depth analysis of personality and symptom dynamics. Written with a therapeutic focus, the interpretive report provides the clinician with a foundation upon which treatment plans can readily be made and includes action-oriented suggestions for therapeutic management.
