Key facts
What is the PTSD and Complex PTSD Explained?
ICD-11 includes complex PTSD, defined by core PTSD symptoms plus disturbances in self-organization: affect dysregulation, negative self-concept and relational difficulties. It typically follows prolonged or repeated trauma.
Why it works
ICD-11 proposals introduced CPTSD as distinct from PTSD (Maercker et al., 2013). Modular, phase-based approaches are recommended for treating CPTSD (Karatzias & Cloitre, 2019).
