To test underlying latent syndromes within schizophrenic syndromes assessed by the Positive and Negative Syndrome Scale (PANSS), a sample of 100 DSM-III-R schizophrenia patients was obtained through a semistructured interview for schizophrenia. Confirmatory factor analysis was used to evaluate the underlying symptomatological dimensions. The positive and negative construct was not confirmed by this study. The three- and four-dimension models obtained higher goodness of fit than the one- or two-dimension models. Models composed of three or four dimensions shared positive and negative syndromes, in addition to "disorder of relating" and/or "disorganization" dimensions. The disorder of relating dimension of PANSS was composed of emotional withdrawal and passive/apathetic social withdrawal. The disorganization dimension comprised two symptoms of PANSS (conceptual disorganization and poor attention) and an item not included in the PANSS: inappropriate affect. It is suggested that a schedule for the assessment of this item be added to the PANSS.
为了检测通过阳性和阴性症状量表（PANSS）评估的精神分裂症综合征中的潜在隐性综合征，通过对精神分裂症患者进行半结构化访谈，选取了100名DSM-III-R精神分裂症患者作为样本。采用验证性因素分析来评估潜在的症状维度。本研究未证实阳性和阴性结构。三维和四维模型比一维或二维模型具有更高的拟合优度。由三维或四维组成的模型除了“关系障碍”和/或“紊乱”维度外，还共享阳性和阴性综合征。PANSS的关系障碍维度由情感退缩和被动/淡漠社交退缩组成。紊乱维度包括PANSS的两个症状（概念紊乱和注意力不集中）以及一个未包含在PANSS中的项目：不适当的情感。建议在PANSS中增加该项目的评估量表。
