We examined the factor structure of the Schizotypal Personality Questionnaire (SPQ; Raine, 1991), using confirmatory factor analysis in 3 experiments, with an aim to better understand the construct of schizotypy. In Experiment 1 we tested the fit of 2-, 3-, and 4-factor models on SPQ data from a normal sample. The paranoid 4-factor model fit the data best but not adequately. Based on the strong basis for the Raine 3-factor model we attempted to improve the fit of the 3-factor model by making 3 modifications to the Raine model. These modifications produced a well-fitting model. In Experiment 2 the good fit of this modified 2-factor model to SPQ scores was replicated in an independent normal sample. In Experiment 3, the modified 3-factor model was successfully extended to include the 3 Chapman schizotypy scales. Together these 3 experiments indicate that the 3-factor model of the SPQ, albeit with some slight modifications, is a good model for schizotypy structure that is not restricted to 1 measure of schizotypal personality traits.
我们使用验证性因素分析，在3个实验中检验了分裂型人格问卷（SPQ；雷恩，1991）的因素结构，旨在更好地理解分裂型特质的结构。在实验1中，我们对来自正常样本的SPQ数据检验了二因素、三因素和四因素模型的拟合度。偏执四因素模型对数据的拟合最佳，但并不充分。基于雷恩三因素模型的坚实基础，我们试图通过对雷恩模型进行3处修改来提高三因素模型的拟合度。这些修改产生了一个拟合良好的模型。在实验2中，这个修改后的二因素模型对SPQ分数的良好拟合在一个独立的正常样本中得到了重复验证。在实验3中，修改后的三因素模型成功扩展到纳入了3个查普曼分裂型特质量表。这3个实验共同表明，SPQ的三因素模型，尽管有一些轻微修改，仍是一个适用于分裂型特质结构的良好模型，且不限于一种分裂型人格特质的测量方法。
