DID
This discussion of DID is highly problematic in a few ways. I have removed references to multiple personality disorder (an old name, no longer used, and disliked by the DID community) and to multiple personalities (alters is the preferred term). The discussion of how systems forms also acknowledges a debate in how it happens, which does not exist in the profession community—doctors agree DID is caused by trauma and traumagenic systems find the idea that DID could be caused by non-abuse-related methods uncomfortable. I would recommend deleting the entire section, as it seems unnecessary.
