The current study provides convergent, discriminant, and incremental validity data for a new measure of schizotypy from the perspective of the five-factor model (FFM) of general personality structure. Nine schizotypy scales were constructed as maladaptive variants of respective facets of the FFM (e.g., Aberrant Ideas as a maladaptive variant of FFM Openness to Ideas). On the basis of data from 143 undergraduates, the convergent validity of these nine scales was tested with respect to seven established measures of schizotypy and the respective facets of the FFM. Discriminant validity was tested with respect to facets from other FFM domains and components of schizotypy. Incremental validity was tested with respect to the ability of the FFM schizotypy scales to account for variance in two established measures of schizotypy, after variance accounted for by respective FFM facets and other established measures of schizotypy were first removed. The findings support the validity of these new scales as measures of schizotypal traits and as maladaptive variants of the FFM.
本研究从五因素人格模型（FFM）的角度提供了一种新的精神分裂症特质衡量标准的会聚、区分和增量有效性数据。九个精神分裂症特质量表被构建为 FFM 各个方面的适应不良变体（例如，异常观念是 FFM 开放性的适应不良变体）。基于来自 143 名本科生的数据，这些九个量表的会聚有效性是通过与七个已建立的精神分裂症衡量标准以及 FFM 的各个方面进行测试的。区分有效性是通过与其他 FFM 领域的方面以及精神分裂症的各个组成部分进行测试的。增量有效性是通过 FFM 精神分裂症量表在两个已建立的精神分裂症衡量标准中解释方差的能力进行测试的，首先在去除 FFM 各个方面和其他已建立的精神分裂症衡量标准解释的方差后。这些发现支持这些新量表作为精神分裂症特质的衡量标准以及 FFM 的适应不良变体的有效性。
