Symptoms of Complex PTSD (Complex Relational Trauma Response)

The diagnosis of Complex PTSD was accepted by the World Health Organization (WHO) in 2018, nearly 30 years after it was first proposed by Dr. Judith Herman. The definition of the diagnosis in the WHO’s classification manual reads as follows:

Complex post traumatic stress disorder (Complex PTSD) is a disorder that may develop following exposure to an event or series of events of an extremely threatening or horrific nature, most commonly prolonged or repetitive events from which escape is difficult or impossible (e.g. torture, slavery, genocide campaigns, prolonged domestic violence, repeated childhood sexual or physical abuse).

All diagnostic requirements for PTSD are met. In addition, Complex PTSD is characterised by severe and persistent 1) problems in affect regulation; 2) beliefs about oneself as diminished, defeated or worthless, accompanied by feelings of shame, guilt or failure related to the traumatic event; and 3) difficulties in sustaining relationships and in feeling close to others. These symptoms cause significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

Based on research into CPTSD, Brewin et al (2017) point out, “There is substantial evidence indicating that CPTSD and PTSD represent distinct patient populations with different symptoms profiles. (See a bibliography of research articles here). The data indicate that Complex PTSD involves 6 symptoms, 3 which are shared with PTSD and 3 which are unique. This means treatment models/approaches must necessarily be different; that is, what is effective in treating PTSD will not necessarily be effective for Complex PTSD.

Shared Symptoms - The following three symptoms are shared with PTSD and are characterized as fear responses to loss of safety and threats to the physical self of harm or death:

  1. RE –Re-experiencing past trauma in the present (flashbacks; nightmares)

  2. AV – Avoidance of traumatic triggers (thoughts, feelings, people, places, things)

  3. SOT – Persistent sense of threat (hypervigilance, heightened startle response)
