We analyzed the psychometric properties of the Positive and Negative Syndrome Scale (PANSS) in a sample of 100 DSM-III-R schizophrenic patients. Our findings coincided with the results of Kay's group in the following points: (1) the PANSS scores were normally distributed; (2) the positive and negative scales showed good interrater reliability; (3) positive and negative syndromes are independent constructs; (4) the positive and negative scales held a high concurrent validity in relation to the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms; and (5) although positive and negative syndromes showed factorial validity, they were not sufficient to account for the whole of the schizophrenic symptoms. Unlike Kay's group, we found a modest internal consistency of the positive scale, indicating that it is composed of several independent components. The data suggest that the distinction between positive and negative symptoms is an oversimplification, and that schizophrenic symptoms can be better conceptualized as composed of, at least three dimensional syndromes: positive, disorganized, and negative.
我们对100名DSM-III-R精神分裂症患者样本的阳性和阴性症状量表（PANSS）的心理测量特性进行了分析。我们的研究结果在以下几点上与凯伊团队的结果一致：（1）PANSS得分呈正态分布；（2）阳性和阴性量表显示出良好的评分者间信度；（3）阳性和阴性综合征是独立的结构；（4）阳性和阴性量表与阳性症状评估量表和阴性症状评估量表具有较高的同时效度；（5）尽管阳性和阴性综合征显示出因子效度，但它们不足以解释所有精神分裂症症状。与凯伊团队不同的是，我们发现阳性量表的内部一致性适中，这表明它由几个独立的成分组成。数据表明，阳性和阴性症状之间的区分过于简单化，精神分裂症症状可以更好地被概念化为至少由三个维度的综合征组成：阳性、紊乱和阴性。
