Diagnostic Criteria Quotes

“It is not unusual for subjects diagnosed with a Dissociative Disorder on the SCID-D to be surprised at having their symptoms validated by a clinician who understands the nature of their disorder.”
― Marlene Steinberg, Interviewer's Guide to the Structured Clinical Interview for Dsm-IV Dissociative Disorders

“In this chapter I restrict myself to exploring the nature of the amnesia which is reported between personality states in most people who are diagnosed with DID. Note that this is not an explicit diagnostic criterion, although such amnesia features strongly in the public view of DID, particularly in the form of the fugue-like conditions depicted in films of the condition, such as The Three Faces of Eve (1957). Typically, when one personality state, or ‘alter’, takes over from another, they have no idea what happened just before. They report having lost time, and often will have no idea where they are or how they got there. However, this is not a universal feature of DID. It happens that with certain individuals with DID, one personality state can retrieve what happened when another was in control. In other cases we have what is described as ‘co-consciousness’ where one personality state can apparently monitor what is happening when another personality state is in control and, in certain circumstances, can take over the conversation.”

“Although Dissociative Disorders have been observed from the beginnings of psychiatry, the Structured Clinical Interview for DSM-III-R Dissociative Disorders (Steinberg 1985) was the first diagnostic instrument for the comprehensive evaluation of dissociative symptoms and to diagnose the presence of Dissociative Disorders.”
― Marlene Steinberg, Structured Clinical Interview for Dsm-IV Dissociative Disorders (Scid-D)

“There is a clear difference between the objectivity and subjectivity of the physical diagnostic criteria, such as that used for Parkinson’s, and the symptomatic diagnostic criteria used for mental disorders in the DSM. Brain diseases, like Parkinson’s, Alzheimer’s, Frontotemporal lobe degeneration, Prion disease, Lewy Body dementia, and many others mentioned in the DSM-V, are diagnosed through objective physical tests, such as MRI scans, detection of misfolded proteins or identification of certain genes. These tests, and therefore the diagnoses of these disorders are objective; the MRI scan either does or does not show a physical indicator of biological dysfunction, misfolded proteins and particular genes are either biologically present or not. In this way, the diagnoses of such brain dysfunctions are objective, they either exist as a matter of fact or they do not. The need for these tests might be brought about because a service user is experiencing symptoms such as ‘postural rigidity’ or ‘tremors’, but these symptoms are not enough alone for a diagnosis of physical brain dysfunction, objective tests must be carried out. In contrast, the diagnosis of mental disorders rests on clusters of
symptoms alone. If we are assessing whether someone is displaying ‘childlike silliness’ or ‘excessive emotionality’, we have no objective tests to aid us, our assessment is made solely on our subjective interpretation of the service user.”
