Beside the syndromic dichotomy (negative-positive), other symptomatic dimensions have been described in schizophrenia. A question of interest is, therefore, to know which symptom structures can be individualized to characterize schizophrenia. Using confirmatory factor analysis in 135 patients, a two-factor model (negative-positive), a three-factor model (negative-positive-disorganization) and a four-factor model (negative-positive-disorganization-relational) were primarily identified with SANS (Scale for the Assessment of Negative Symptoms) and SAPS (Scale for the Assessment of Positive Symptoms). In contrast, no models could be identified with PANSS (Positive and Negative Syndrome Scale). The results confirm the relevance of other syndrome dimensions, beside the negative and positive ones and suggest that SANS-SAPS was more useful than PANSS in identifying an adequate dimensional factor structure of schizophrenic symptoms.
除了症状二分法（阴性-阳性）外，精神分裂症还存在其他症状维度。因此，一个有趣的问题是，了解哪些症状结构可以个体化以表征精神分裂症。在135名患者中使用验证性因素分析，主要用阴性症状评定量表（SANS）和阳性症状评定量表（SAPS）确定了双因素模型（阴性-阳性）、三因素模型（阴性-阳性-紊乱）和四因素模型（阴性-阳性-紊乱-关系）。相比之下，阳性和阴性症状量表（PANSS）无法确定任何模型。结果证实了除阴性和阳性症状维度外其他症状维度的相关性，并表明SANS-SAPS在识别精神分裂症症状的适当维度因素结构方面比PANSS更有用。
