The increasing use of schizoid personality scales with normals has led to a number of validation studies, but to date there are no published analyses of the factorial structure of these scales. This study presents results of factor analyses of schizoid personality scales in an initial attempt to delineate their factorial structure. Questionnaires were administered to 114 male and female undergraduates and factor analysed using Varimax, Quartimax, and Oblique rotations. A two-factor varimax solution yielded a first factor accounting for 49 per cent of total unrotated variance with high (0.70 to 0.91) loadings from Hallucinatory predisposition, Perceptual aberration, Schizophrenism, STA and STB scales, and was interpreted as reflecting a general factor of schizoid personality disorder. Psychoticism and Social anhedonia loaded on a second factor accounting for 20 per cent of the variance which was uncorrelated (r = 0.09) with factor 1. This factor solution was closely replicated using quartimax and oblimin rotation criteria. It is concluded that Social anhedonia and Psychoticism represent a separate dimension from other scales which reflect the more positive features of schizoid personality.
在普通人群中，分裂样人格量表的使用越来越多，这引发了多项效度研究，但迄今为止，尚未有关于这些量表因子结构的已发表分析。本研究呈现了分裂样人格量表的因子分析结果，这是首次尝试描绘其因子结构。对114名男女本科生进行问卷调查，并使用方差最大化、四次方最大化和斜交旋转进行因子分析。一个两因子方差最大化解决方案产生了第一个因子，该因子占总未旋转方差的49%，来自幻觉易感性、感知畸变、精神分裂症、STA和STB量表的载荷较高（0.70至0.91），并被解释为反映了分裂样人格障碍的一个一般因子。精神病态和社交快感缺失载荷在第二个因子上，该因子占方差的20%，与因子1不相关（r = 0.09）。使用四次方最大化和斜交旋转标准，该因子解决方案得到了紧密重复。研究得出结论，社交快感缺失和精神病态代表了一个与其他反映分裂样人格更积极特征的量表不同的维度。
