A Meta-analysis on Childhood Trauma Involved in Dissociative Identity Disorder

Abstract

Dissociative identity disorder (DID) is a psychobiological syndrome referred to the appearance of extra identities and memories which cause the changes in cognize and behaviour. Evidence has shown that early childhood trauma plays a key role in the genesis of DID. This paper compiles and analyzes the amount of emotional and physical neglect and abuse as well as sexual abuse in DID patients early childhood. Evidence shows that DID patients report more experience in every type of trauma than healthy people. Then a meta-analysis is made to illustrate the influence of different types of traumatization on DID patients, giving a result that the origin of DID is more likely comes from emotional abuse and neglect, followed by sexual abuse, and is least likely to come from physical abuse and neglect.
