“Dissociation, the term that underlies the dissociative disorders including DID, lacks a precise, empirical, and generally agreed upon definition.”
“The most widely used model of dissociation conceptualizes DID as at one extreme of a continuum of dissociation, with flow at the other end, though this model is being challenged.”
“The prevailing post-traumatic model of dissociation and dissociative disorders is contested.It has been hypothesized that symptoms of DID may be created by therapists using techniques to “recover” memories (such as the use of hypnosis to “access” alter identities, facilitate age regression or retrieve memories) on suggestible individuals. Referred to as the “sociocognitive model” (SCM), it proposes that DID is due to a person consciously or unconsciously behaving in certain ways promoted by cultural stereotypes, with unwitting therapists providing cues through improper therapeutic techniques. This behavior is enhanced by media portrayals of DID.”
“Proponents of the SCM note that the bizarre dissociative symptoms are rarely present before intensive therapy by specialists in the treatment of DID who, through the process of eliciting, conversing with and identifying alters, shape, or possibly create the diagnosis.”
“DID is among the most controversial of the dissociative disorders, and among the most controversial disorders found in the DSM-IV-TR.[7] The primary dispute is between those who believe DID is caused by traumatic stresses forcing the mind to split into multiple identities, each with a separate set of memories,[13][17] and the belief that the symptoms of DID are produced artificially by certain psychotherapeutic practices or patients playing a role they believe appropriate for a patient suffering from DID.”
“Psychiatrist Joel Best notes that the idea that a personality is capable of splitting into independent alters is an unproven assertion that is at odds with research in cognitive psychology.”
“There is a general lack of consensus in the diagnosis and treatment of DID.”

Far from me to tell you you ain’t ill, but your problem may have some other name.
