“Extreme versions of DID occasionally develop in response to particularly horrific ongoing trauma (e.g., children exploited through involvement in years of forced prostitution), with so-called poly-frgamentation, encompassing dozens or even hundreds of personality states. In general, the complexity of dissociative symptoms appears to be consistent with the severity of early traumatiation. That is, less severe abuse will result in fewer dissociative symptoms, and more severe abuse will result in more complex dissociative disorders.”
