虽然阳性和阴性症状量表(PANSS)的开发人员将项目分为三个分量表,因子分析表明,五因素模型更好地表征PANSS数据。然而,由于对使用哪种模型缺乏共识,限制了研究间PANSS变量的可比性。我们从已发表的因子分析中计算“投票”,以得出共识模型。其中一个组合的上级拟合在我们的白人样本(n=458,CFI = 0.970)和不同的日本样本(n=164,CFI = 0.964)中,相对于原始的三个子量表模型,项目分类为因子,在所审查的研究中高度一致。
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.
