Complex post-traumatic stress disorder: a new diagnosis in ICD-11

  • Chris R. Brewin (a1)

Summary

The World Health Organization's proposals in ICD-11, released for comment by member states in 2018, introduce for the first time in a major diagnostic system a distinction between post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (CPTSD). This article sets the new diagnosis of CPTSD within the context of previous similar formulations, describes its definition and requirements, and reviews the evidence concerning its epidemiology, differential diagnosis, assessment and treatment.

LEARNING OBJECTIVES

After reading this article you will be able to:

  • understand the relationship between CPTSD and precipitating events
  • distinguish CPTSD from PTSD and borderline personality disorder
  • recognise current issues and practices in psychological treatment.
