The debate over the validity of this condition, whether as a clinical diagnosis, a symptomatic presentation, a subjective misrepresentation on the part of the patient, or a case of unconscious collusion on the part of the patient and the professional is considerable. Unlike other diagnostic categorizations, there is very little in the way of objective, quantifiable evidence for describing the disorder.
The main points of disagreement are these:
- Whether DID is a real disorder or just a fad.
- If it is real, is the appearance of multiple personalities real or delusional?
- If it is real, whether it should it be defined in psychoanalytic terms.
- Whether it can, or should, be cured.
- Who should primarily define the experience-therapists, or those who believe that they have multiple personalities.
Skeptics claim that people who present with the appearance of alleged multiple personality may have learned to exhibit the symptoms in return for social reinforcement. One case cited as an example for this viewpoint is the "
Sybil" case, popularized by the news media. Psychiatrist Herbert Spiegel stated that "Sybil" had been provided with the idea of multiple personalities by her treating psychiatrist,
Cornelia Wilbur, to describe states of feeling with which she was unfamiliar.
One of the primary reasons for the ongoing recategorization of this condition is that there were once so few documented cases (research in 1944 showed only 76
[40]) of what was once referred to as multiple personality. Dissociation is recognized as a symptomatic presentation in response to
trauma, extreme emotional stress, and, as noted, in association with
emotional dysregulation and
borderline personality disorder[41].
