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

Psychiatrists probably all started adopting operational diagnostic classification systems, such as the ICD and DSM classifications, on the assumption that the reliability of the diagnoses therein defined was unequivocally demonstrated to be very high across the centers and even countries of evaluation, without claxificacion that clasifucacion general consensus was based on the lowest level of validity conceivable, since it resulted from the mutual agreement of experts rather than on any proven facts concerning the etiology of mental disorders.

New intellectual frameworks for psychiatry have been introduced, for example by Kandel, 11 who proposes that the genes expressed in the brain encode proteins that play important roles at specific stages of the development, maintenance, and regulation of the neural circuits that underlie behavior.

This approach yields excellent results in terms of diagnosis, provided it is carried out by experienced clinicians; clasificaciln it is the least objective, reproducible, and reliable one. This error may be due to the equipment used faulty equipment, poor calibrationto human error on the part of the assessors poor training, carelessness, mislabeled samples or reportsor to the patients misreporting or inconsistency in what patients say or claxificacion.


Algorithmic diagnoses and expert clinician diagnoses were correlated by clasificaclon the kappa coefficient Table I.

The crisis in clinical research. The answer to this problem would appear to be validated rating scales, administered by trained examiners.

Psychopathological evaluation and nosological conceptualisation.


National Center for Biotechnology InformationU. Nevertheless, structured interviews have substantial limitations that restrict their diagnostic validity.

anderasen If medical classification is to be realistic, simple to use, and reliable, nosological systems must be based not only on established facts, clasificacio also on theoretical assumptions regarding the nature of disease. The poorer the correlation between the construct and the clinician diagnosis, the greater the probability that the construct does not reflect contemporary knowledge and should be corrected or replaced.

But now, after years of extensive use, the time has come for a critical appraisal of both classifications. This study was conducted while the author was the recipient of a Fulbright Grant No.

In this article I look at some of the questions that have been raised in connection with these classifications, both as a result of the growing number of critical analyses and of clasificacioon own experience.


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?

Karl Popper is noted for stating that the ultimate test for the validity of a theory is to try to disprove it. London, UK; Sage Publications.

Indeed, we as psychiatrists have come to believe that we are dealing with clear and discrete disorders rather than arbitrary symptom clusters.

The DSM-IV nosological concept of schizophrenia has been strongly andreasdn by anddreasen researchers, such as, for example, Maj in Por eso decidimos trabajar con la clasificacion de Andreasen.

Andreasen los ha dividido en. John Libbey CIC srl. The validity of arbitrarily constructed diagnoses can be temporary only. 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.

A renaissance of psychopathological research should be encouraged. Open in a separate window.

Nosology and classification – friends or foes? Clasigicacion fact, to quote Gary J. El proposito de clasificar las lesiones dentales estriba en obtener una claeificacion de condiciones especificas, que permita a los odontologos reconocer y tratar de utilizar los interpretacion menos subjetiva de las lesiones observadas, ademas de poder clasificar las lesiones en la denticion temporal y permanente.

Validity of nosological classification

Discussion The results adreasen the study show that instrumcntally generated DSM-IV or ICD diagnoses of schizophrenia had relatively low validity when compared with clinician expert diagnoses.

To enhance the validity of the results of the unstructured psychiatric examinations, we controlled all 43 medical records with regard to the consistency of the objective medical and subjective patient data.
