The authors investigated the latent structure of schizotypal personality features using taxometric analysis in a large sample of individuals from clinical and nonclinical populations. A total of 7,072 community adults and 270 psychiatric patients participated in the study by responding to the eccentricity, distrust, and isolation scales from the Dimensional Clinical Personality Inventory (IDCP). Data were analyzed using three different taxometric techniques, MAMBAC, MAXEIG, and L-Mode. The indicators proved valid for the taxometric analysis (d ≥ 1.25). The comparison curve fit index (CCFI) coefficients from the three methods used were close to zero, and the average CCFI was lower than .40, clearly indicating a dimensional structure for schizotypal personality features. These findings suggest that schizotypal personality traits occur in levels, with no evidence of any natural boundary between clinical and nonclinical manifestations. Results from other studies that were consistent with a categorical structure may be due to methodological weaknesses.

中度偏心：分裂型人格特征潜在结构中维度的证据。

作者通过对来自临床和非临床人群的大量个体样本进行分类分析，研究了分裂型人格特征的潜在结构。共有 7,072 名社区成年人和 270 名精神病患者参与了这项研究，他们对 Dimensional Clinical Personality Inventory (IDCP) 中的古怪、不信任和孤立量表做出了回应。使用三种不同的分类技术（MAMBAC、MAXEIG 和 L-Mode）分析数据。这些指标证明对分类分析有效（d ≥ 1.25）。所用三种方法的比较曲线拟合指数（CCFI）系数接近于零，平均CCFI低于0.40，清楚地表明了分裂型人格特征的维度结构。这些发现表明，分裂型人格特质发生在多个层次上，没有证据表明临床和非临床表现之间有任何自然界限。与分类结构一致的其他研究的结果可能是由于方法学上的缺陷。
