Complex post-traumatic stress disorder (complex PTSD) is a severe mental disorder that emerges in response to traumatic life events. Complex PTSD is characterised by three core post-traumatic symptom clusters, along with chronic and pervasive disturbances in emotion regulation, identity, and relationships. Complex PTSD has been adopted as a new diagnosis in the ICD-11. Individuals with complex PTSD typically have sustained or multiple exposures to trauma, such as childhood abuse and domestic or community violence.
