Is multiple personality disorder associated with child abuse?

Yes. As dr. Amster states, this disorder is called dissociative identity disorder. It's very rare (.1 - 1% of population), and many people with it have suffered longstanding child abuse along with severe emotional neglect. These kids (& later adults) deal with their intense pain by unconsciously sequestering and experiencing only portions of self at a time. Treatment facilitates healing and integration.
Multiple personality. Yes. Typically, incredible amounts of physical and sexual abuse in early to mid childhood that goes unnoticed and therefore unchecked, as well as severe detachment disorders.
Adaptation. Multiple personality disorder is a dissociation disorder, where a person's mind decides that whatever trauma they have is not worth dealing with, and assigns it to "somebody else". Child abuse could certainly fall under that, depending on the child, the trauma, and the child's coping mechanisms and support. Most multiple personalities aren't like tv, though, they are generally a form of denial.
