Abstract

The authors examined whether three indicators of Schizotypy, the Revised Social Anhedonia Scale (RSAS), Magical Ideation Scale (MIS), and Perceptual Aberration Scale (PAS), identify a common latent class or taxon as conceptualized by P. E. Meehl (1962, 1990). The separate and joint latent structures of these scales were evaluated using taxometric methods in two large, independent samples. Replicating prior findings, the RSAS and PAS each identified latent taxa with base rates approximating.10. Results for the taxonicity of the MIS were less consistent. Analyses of joint latent structure indicated that the RSAS-identified taxon was essentially independent of constructs measured by the PAS or MIS. Measures commonly thought to tap the same latent class, conjectured to be schizotypy, do not share this property.

摘要

作者们研究了精神分裂症型人格的三个指标，即修订版社交快感缺失量表（RSAS）、神奇观念量表（MIS）和感知偏差量表（PAS），是否能识别出如P.E.米尔（1962年，1990年）所概念化的一个共同的潜在类别或分类群。在两个大型独立样本中，使用分类法评估了这些量表的单独和联合潜在结构。重复先前的研究结果，RSAS和PAS各自识别出潜在分类群，其基础比率约为0.10。MIS的分类性结果不太一致。联合潜在结构分析表明，RSAS识别出的分类群基本上独立于PAS或MIS所测量的结构。通常认为用于挖掘同一潜在类别的测量方法，推测为精神分裂症型人格，并不具有这一特性。
