Diagnostic Criteria for Narcissistic Personality Disorder

Current Diagnostic Framework

  • The World Health Organization's ICD-11 has restructured personality disorder diagnosis by replacing discrete categories with a single personality disorder diagnosis characterized by problems in self-functioning and interpersonal dysfunction, with severity grading and optional trait specification, according to the World Health Organization 2, 1
  • The ICD-11 approach includes problems in self-functioning, such as identity disturbance, and interpersonal dysfunction, such as difficulty managing relationships and conflict, as diagnosed by a qualified healthcare professional 2
  • Severity grading in the ICD-11 approach includes mild, moderate, or severe, and optional trait specification includes dissociality, negative affectivity, detachment, disinhibition, anankastia, or borderline pattern, as recommended by the World Health Organization 2, 1

Assessment Approach

  • The American Psychiatric Association recommends gathering information from multiple sources using varied developmentally sensitive techniques, as self-reporting may be unreliable and confirmation from multiple informants is necessary, according to the American Psychiatric Association 1
