Although the developers of the Positive and Negative Syndrome Scale (PANSS) grouped items into three subscales, factor analyses indicate that a five-factor model better characterizes PANSS data. However, lack of consensus on which model to use limits the comparability of PANSS variables across studies. We counted "votes" from published factor analyses to derive consensus models. One of these combined superior fit in our Caucasian sample (n=458, CFI=.970), and in distinct Japanese sample (n=164, CFI=.964), relative to the original three-subscale model, with a sorting of items into factors that was highly consistent across the studies reviewed.
虽然阳性和阴性症状量表(PANSS)的开发者将项目分为三个分量表,但因素分析表明,五因素模型能更好地描述 PANSS 数据。然而,对于使用哪种模型缺乏共识,限制了 PANSS 变量在研究之间的可比性。我们对已发表的因素分析进行了“计数”,以得出共识模型。其中一个模型在我们的白种人样本(n=458,CFI=.970)和独特的日本样本(n=164,CFI=.964)中表现出更好的拟合,与原始的三分量表模型相比,与综述研究中高度一致的项目分类因素相比。
