摘要:

A sample of pre-1967 case records with a hospital diagnosis of schizoaffective disorder were presented for rediagnosis to members of the present staff of the Institute of Psychiatry/Maudsley Hospital. The raters were asked to make a diagnostic choice of either schizophrenia or schizoaffective disorder or affective disorder and indicate how useful they would consider certain treatments for the present episode and for the long term. There was a significant trend in diagnosis to affective disorder but this trend was not correlated with the usefulness of certain treatments, e.g. lithium, a drug which had not been in use before 1967.

摘要:

This study has focussed on a 10-item Brief Psychiatric Rating Scale (BPRS) subscale for the quantification of schizophrenic states. Seven psychiatrists interviewed jointly patients who all fulfilled the DSM-III criteria of schizophrenia, and in a subsequent pencil-and-paper procedure a judgment analysis was performed. The reliability analysis showed that less experienced BPRS raters made less consistent judgments implying the cautionary statement that the proper use of a scale for schizophrenia requires specialized training with the scale. The validity analysis showed that the BPRS items had an additive relationship implying that the sum of these items is a sufficient statistic for the measurement of severity of schizophrenic states. Finally, the results seem to indicate, that the underlying dimension defined by the 10-items BPRS subscale includes hierarchically the negative and positive symptoms of schizophrenia.
