在一项精神康复研究中，采用30项阳性和阴性症状量表（PANSS）和18项精神简要评定量表（BPRS）对154名患者进行了同时评定。虽然这两种工具都具有出色的量表间信度，但PANSS始终更好：在两种工具共有的18个症状项上，PANSS在14个症状项上具有更高的组内信度；PANSS在阳性、阴性和总分上均高于BPRS。加权Kappas比较共享项目显示，大多数是不可互换的，只有三个系数在优秀范围内。然而，综合征量表得分高度相关，导致阴性精神分裂症的分类相似。PANSS的12个项目中有10个不包括在BPRS中，与BPRS项目有低零阶相关性，这表明它们测量的症状不同于BPRS所测量的症状，应该增加临床预测能力。在我们对精神分裂症患者康复的研究中证明了这一点。PANSS症状评分解释了七项工作表现测量中高达55%的差异，而BPRS在七项测量中的六项具有较低的预测能力。我们认为PANSS在精神分裂症的临床研究中可能优于BPRS，而且大多数BPRS项目与相同名称的PANSS项目不可互换。
In a psychiatric rehabilitation study, 154 concurrent ratings were performed using the 30-item Positive and Negative Syndrome Scale (PANSS) and the 18-item Brief Psychiatric Rating Scale (BPRS). Although both instruments had excellent interrater reliability, the PANSS was consistently better: on the 18 symptom items the two instruments share, the PANSS had higher intraclass r's on 14; for the syndromes, the PANSS was higher than the BPRS on positive, negative, and total. Weighted Kappas comparing shared items revealed that most were not interchangeable, with only three coefficients in the excellent range. However, syndrome scale scores were very highly correlated and resulted in similar classification for negative schizophrenia. Ten of the 12 items of the PANSS not included in the BPRS had low zero-order correlations with BPRS items, which suggests that they measure symptoms distinct from those measured by the BPRS and should add to clinical predictive power. This proved true in our study of rehabilitation of patients with schizophrenia. PANSS symptom ratings explained up to 55% of the variance on seven measures of work performance, whereas the BPRS had lower predictive power on six of the seven measures. We concluded that the PANSS may be superior to the BPRS in clinical research on schizophrenia and that most BPRS items are not interchangeable with identically named PANSS items.
