精神分裂症症状的因子结构与非精神分裂症人群中典型症状的因子结构相似，这一假设得到了一些支持。然而，迄今为止，还没有研究检查过人格障碍患者的分裂型症状。在这项研究中，验证性因素分析进行了测试的相对拟合的几个模型的因素结构的典型症状诊断为人格障碍患者。EQS：采用结构方程程序对213例符合至少一种人格障碍诊断的患者进行结构化临床访谈，分析典型人格障碍（SPD）的DSM-III症状。总样本的一个亚组也进行了DSM-III-R标准的评价（n = 143），以测试SPD的DSM-III-X症状的竞争模型。一个三因素模型组成的认知知觉，人际关系和偏执的因素产生了最好的拟合数据相对于其他模型进行测试。这些结果表明，精神分裂症症状的三因素模型可能不完全对应于临床人群中表现出的较轻的典型症状的潜在因素。未来的研究应关注SPD与精神分裂症的异同。
There is some support for the hypothesis that the factor structure of schizophrenia symptoms is similar to the factor structure of schizotypal symptoms in nonschizophrenia populations. However, no studies to date have examined schizotypal symptoms in patients with personality disorders. In this study, confirmatory factor analyses were conducted to test the relative fit of several models of the factorial structure of schizotypal symptoms in patients diagnosed with personality disorders. The EQS: Structural Equations Program was used to analyze DSM-III symptoms of schizotypal personality disorder (SPD) based on structured clinical interviews with 213 patients meeting a diagnosis for at least one personality disorder. A subgroup of the total sample was also evaluated for DSM-III-R criteria (n = 143) to test competing models of the DSM-III-X symptoms of SPD. A three-factor model consisting of a cognitive-perceptual, interpersonal, and paranoid factor yielded the best fit to the data relative to the other models tested. These results suggest that the three-factor model of schizophrenia symptoms may not entirely correspond to the factors underlying milder schizotypal symptoms expressed in a clinical population. It is suggested that future research focus on both the similarities and the differences between SPD and schizophrenia.
