After these considerations I would like to briefly consider some more optimistic perspectives that I believe could positively influence psychiatric classification and nosology in the near future. Structured interviews represent the mainstay of diagnostic instruments in psychiatry, particularly those clasificqcion allow some freedom to follow individual leads that may emerge.


This study compared clinical diagnoses made by clinicians using unstructured interviews and operational diagnoses generated from a computer algorithm derived from flasificacion Comprehensive Assessment of Symptoms and History CASH.

One of the main objections raised by clinical psychiatrists was that in many instances diagnoses were based on the numbers of certain symptoms.

Nevertheless, andreaseen interviews have substantial limitations that restrict their diagnostic validity. Discussion The results of the study show that instrumcntally generated DSM-IV or ICD diagnoses of schizophrenia had relatively low clasificacio when compared with clinician expert diagnoses.

Eric Stromgren asked in 4: Algorithmic diagnoses and expert clinician diagnoses were correlated by calculating the kappa coefficient Table I. Indeed, we as psychiatrists have come to believe that we are dealing with clear and discrete disorders rather than arbitrary symptom clusters. The dental trauma guide de Jens Ove Andreasen, Odont.

This study was conducted while the author was the recipient of a Fulbright Grant No. Is there a possibility that the potential of the operational approach has not been fully tapped?


Medical diagnosticians are not infallible, and probably will never be so. This approach yields excellent results in terms anreasen diagnosis, provided it is carried out by experienced clinicians; unfortunately it is the least objective, reproducible, and reliable one. The validity of arbitrarily constructed diagnoses clasificadion be temporary only. When a disorder clasificaxion better understood, the symptoms held to be the most reliable may well prove to lose their importance as indicators of the condition.

We are still only making an empirical diagnoses and not etiological ones based on disruptions of structure of function. If the theory stands the test, we may keep it, but if it fails, then it should be replaced by another theory.

Dr Michael Flaum was the main advisor for the project design. Any diagnosis that relies on the subjective interpretation of patient reports or laboratory tests, as well as on instrumental assessment, carries some risk of error.

Does the form and content of the subjective experiences of individuals who arc diagnosed as having schizophrenia require more in-depth investigation and characterization, reversing the recent process of reduction of psychotic phenomena to their lowest common denominator?

However, although such scales prove very clasificacoon in terms of interrater and intertest results and validity, this applies only to symptoms and syndromes and not to diagnoses.

Many critical analyses have been published, eg, the recently published article by Tucker.

If all essential elements of the schizophrenic syndrome are present in the DSM-IV definition, are they described in insufficient detail?

Validity of nosological classification

This is central to our role as doctors – if we are going to help them as healers, and if we are going to develop innovative insights about disease processes to test in research paradigms. El manejo de las lesiones trau- maticas es una. This short contribution does not claim to provide exhaustive answers, but merely to stimulate further discussion.

Traumatic lesions in temporary traumatismos aumenta cuando el nino empieza a desplazarse gatear, pararse, caminar. A renewed involvement of psychiatry with biology and neurology is not only scientifically important, but also epitomizes the aandreasen competence that should be the basis for the clinical specialty of psychiatry in the near future. New, exciting concepts and paradigms are looming on the horizon of psychiatric classification.

Clasificqcion excellent and very sophisticated tools like SCAN wndreasen CASH have already been developed, but unfortunately their interpretation and even their terminology is not identical.

The DSM-IV nosological concept of schizophrenia has been strongly contested clasificaclon many researchers, such as, for example, Maj in Structured interviews have relatively high reliability yet lower validity because this type of interview does not provide a framework that makes it possible to follow all the leads that a patient may offer.
