Psychosis involves a break with reality, believing things that are untrue, or having hallunciations about things that aren’t there.

14. Dissociative Disorders: Dissociative Identity Disorder Module 31: Dissociative, Schizophrenia, and Personality Disorders

15. Dissociative Identity Disorder Rare and controversial dissociative disorder in which an individual experiences two or more distinct and alternating personalities Formerly called multiple personalities –Before the 1970s fewer than 100 cases had ever been reported. –In the 1980s alone, reports of more than 20,000 diagnosed cases appeared, almost all of them in North America

16. Controversy Psychologists debate whether is really exists. Are today’s clinicians simply more knowledgeable and willing to make a diagnosis? Are there better diagnostic rules (thus reducing the number of cases that were misdiagnosed as other things, like schizophrenia)? Skeptics believe the power of suggestion has been at work. Clinicians (who have read about the disorder) may be unintentionally suggesting multiple personalities to their clients.
