my instinct is to say that I believe the answer is no, not by itself and that there most likely are other factors involved (like how if you're being mistreated to the extent it causes DID this would also strongly imply that your parental figure is not attuned to you emotional needs/emotionally absent), but my other instinct is to say that I am not the arbiter of how your trauma affected you.

I would not focus on how much trauma you've experienced to validate/invalidate the presence of a complex dissociative disorder. some people experience things worse than 99% of other people, and they don't develop complex dissociative disorders, so I can't really responsibly tell you what does or does not "qualify" for enough trauma. the DSMV does not care about what qualifies as enough trauma. it's not part of the criteria. trauma can cause OCD, but we don't culturally validate or normalize the idea that there's an "amount of trauma" that qualifies for someone to develop OCD, and I don't think that we should do the same for DID. I believe that DID develops as a result of trauma, but I do not believe that quantifying a qualifying amount is a helpful framework for exploring or determining what you have. you experience what you experience regardless of whether you're "allowed to" or not
