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 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.

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
