Hypnosis creates multiple personality: Myth or reality?

Since before the turn of the century, multiple personality has been associated with hysteria and hypnosis. The myth that hypnosis can create multiple personality is examined in this paper by reviewing studies that have suggested or implied a casual link between hypnosis and multiple personality. While it is possible that personality fragments can appear under hypnosis, there is no evidence that personalities with separate life histories and a full range of affect can be created with hypnosis. The author concludes that hypnosis is a valuable tool in diagnosing and treating multiple personalities.
