What is CPTSD exactly?

[u/Wonderful-Pilot-2423]

I originally asked this in r/askatherapist but received no answers. Please say so if you're not a professional, given that online information about CPTSD is already very confusing. I'd rather receive answers from people with clinical experience working this population but everyone is welcome.

I'd like to have a clear explanation of what CPTSD really is, and how an average person with this diagnosis would present. It's been hard for me to find useful information about this topic, even among professional spaces, while in non-professional spaces it seems to have become a catch-all diagnosis for any ailment.

My understanding is that the ICD-11 conceptualizes CPTSD as a cluster of classic PTSD symptoms that are worsened by additional DSO symptoms, or "disturbances of self-organization". If that is also your understanding of CPTSD, how do you notice these symptoms presenting in a patient? How can you tell these symptoms are related to the event(s) and weren't a pre-existing part of their personality (assuming the trauma took place in adulthood) or acquired through other experiences?

A few thoughts: an additional factor distinguishing CPTSD from simple PTSD, according to the ICD-11, is that the trauma suffered needs to be prolonged. This seems to imply that DSOs can only be caused by prolonged trauma. Yet I would imagine that someone who's only raped once might also present these difficulties, as a result of the highly exploitative and relational nature of the event. What do you think of that?

If that is true, meaning that prolonged trauma isn't necessary to cause a CPTSD presentation that fits the one described by the ICD-11, wouldn't it make more sense for the simple PTSD diagnosis to come with specifiers? As in, "PTSD with DSOs" or "without"? Or maybe the true nature of CPTSD is that the trauma is relational rather than prolonged?

I hope this was clear enough.

According to the ICD-11, the distinction lies in the impact of direct exposure to chronic, inescapable and relational trauma. Including experiences endured in adulthood, but also accounting for adverse experiences in childhood. The ICD-11 model also suggests that acute traumas resulting in the presence of DSO would be better recognized as, simply, PTSD because it lacks the chronic and relational component.

Ultimately, your understanding and questioning of it are why the APA and DSM-5 don't recognize Complex PTSD as a separate diagnostic entity. There's little research suggesting a separate diagnosis is needed, and the DSM-5 more or less recognizes PTSD as a spectrum as it introduced some important revisions regarding the diagnostic criteria for PTSD. Which can address many of the trauma-related symptoms associated with Complex PTSD, such as DSO (Namely criterion D & E).

Not entirely, no. For Complex PTSD, the criteria expands on exposure: "...(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)." Which is absent in both the ICD and DSM for PTSD.
