While the schizoid dimension of personality has often been thought to be unitary, it has recently been suggested that several dimensions may be involved. In this study two separately derived normal population personality scales from within the psychoticism domain, the Rust Inventory of Schizotypal Cognitions (RISC), a scale designed to measure the positive cognitive schizotypal dimension, and the Eysencks' P scale from within the Eysenck Personality Questionnaire, were administered to a group of 608 Venezuelan university students. It was found that the RISC and the EPQ had only a small correlation of 0.12. It was concluded that at least two dimensions were involved in the schizophrenic/normal spectrum, and that the EPQ Psychoticism scale was in fact measuring a dimension of personality disorder rather than a general factor of psychoticism.
虽然人格的分裂样维度通常被认为是单一的，但最近有人提出可能涉及几个维度。在这项研究中，从精神病态领域内分别得出的两个正常人群人格量表，即用于测量积极认知分裂样维度的量表——拉斯特分裂型认知量表（RISC），以及艾森克人格问卷中的艾森克P量表，被施用于一组608名委内瑞拉大学生。结果发现，RISC和EPQ的相关性仅为0.12。研究得出结论，精神分裂症/正常谱系至少涉及两个维度，并且EPQ精神病态量表实际上测量的是人格障碍维度，而非精神病态的一般因素。
