This has been around a long time @
shimmerz and even your above link cites "complex trauma" within it. Complex trauma is very real, and they (the team who study complex trauma) have always been onto something, and in fact are some of the worlds experts on trauma. That doesn't change their claim for CPTSD. Complex trauma does not make CPTSD, and trauma should not be immediately established with PTSD, period.
The idocracy of this debate is that I've read from people here diagnosed, claimed, as CPTSD, yet those very people will also argue that PTSD should not be the first point of call when trauma is mentioned. The team that study complex trauma have done this exact thing, in trying to take pieces of multiple different diagnoses and lump them as complex PTSD. They should have never gone this route IMHO, and should have always tried to establish themselves for a unique diagnosis, because complex trauma can create unique problems, however; even though complex trauma creates unique problems than what PTSD is, it still does not negate that existing diagnoses already exist which can be used as comorbid diagnostic application to a primary diagnosis.
I often get the very impression from anyone labelled with CPTSD, that they desire to hold onto something that doesn't exist, is unique because it doesn't exist, and try and fight the reality of mental health diagnosis.
People think I'm closed to CPTSD, when in fact I'm anything but... however; I don't perpetuate nonsense. It wouldn't matter what diagnosis you tossed my way, if it is purely conjecture, zero officially agreed upon diagnostic application for trial purpose, then I would say the same thing. Medicine has a physicality to it, so when something new comes along, they have some physical and tangible to make their claim. Mental health... they don't. It is all based on what a person says, which could be anything, an interpretation a specialist has who is listening, then really all just best guess / statistical data to any type of majority basis for some type of credibility to be established.
This is why mental health doctrine changes so much. Social pressures see mental health diagnoses dropped, added and changed, where medical doesn't because of that physical correlation to substantiate validity. Mental health practitioners who have created a standardised model for the world are trying atleast to provide that standardisation, so mental health stops being laughed at. This nonsense with CPTSD just continues to perpetuate what a joke the mental health industry still is today. It isn't just CPTSD, there are lots of other diagnoses making it a continuing joke.
For those of us who suffer mental health, we all continue to garnish stigma from society as a result, because the very people trusted to bring credibility, also bring disharmony due to their unique causes. Mental health is trying to work as a collective, when still there are so many factions within it that create disharmony.
