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.
本研究聚焦于一个用于量化精神分裂症状态的10项简明精神病评定量表（BPRS）子量表。七位精神科医生共同访谈了所有符合精神分裂症DSM-III标准的患者，并在随后的纸笔程序中进行了判断分析。可靠性分析表明，经验较少的BPRS评分者做出的判断一致性较低，这意味着需要谨慎声明，即正确使用精神分裂症量表需要接受该量表的专门培训。效度分析表明，BPRS项目具有累加关系，这意味着这些项目的总和是测量精神分裂症状态严重程度的充分统计量。最后，结果似乎表明，由10项BPRS子量表定义的潜在维度在层次上包括精神分裂症的阴性和阳性症状。
