Here, here....I'm glad the top comment is a disclaimer, seriously who allows this crap to be "published" without proper credentials....not to mention if this person was really working on a master THIS would surely go against ethical guidelines torching any future employer from giving them a job. This kind of quack pseudoscience is why there are so many kids running around fake claiming disorders because they want to be trendy. This is a complete slap in the face for people who actually do suffer from DID.
As DID it's self is rare, fictives are rare in people with DID. It's also very rare for those suffering from DID to form new alters in adulthood. DID is a COPING mechanism for severe and repeated trauma that develops before age 8 when the sense of self is developing. You cannot develop DID after this, you can have dissosiative episodes in respnce to trauma but that is not the same as DID or even OSDD. Experience of trauma in early childhood does not mean a person will develop DID. The DSM would not exist if all trauma = DID. Many mental disorders have overlaping symptoms. Getting a diagnosis for DID takes years and is extreamly rare to be given prior to the age of 18.... no credible clinician would but their name next to these crappot claims. I'm so ready for the "having severe mental illness is cool" trend to be over with.
