Abstract. The vulnerability for schizophrenia-spectrum disorders is expressed across a continuum of clinical and subclinical symptoms and impairment known as schizotypy. Schizotypy is a multidimensional construct with positive, negative, and disorganized dimensions. Openness to experience offers a useful personality domain for exploring multidimensional schizotypy. This study examined the factor structure of openness and its relation to schizotypy using the Multidimensional Schizotypy Scale-Brief (MSS-B) in a sample of 2,236 adults. Positive schizotypy was broadly associated with elevated openness and negative schizotypy was generally associated with diminished openness. Principal components analysis of 15 openness facets replicated the four-factor structure of openness including Fantasy/Feelings, Eccentricity, Nontraditionalism, and Ideas factors. All three schizotypy dimensions were associated with Eccentricity. Positive schizotypy was associated with Fantasy/Feelings, whereas negative schizotypy was inversely associated with Fantasy/Feelings. Results support the construct validity of the MSS-B, use of alternative openness measures in examining schizotypy, and the multidimensional structures of schizotypy and openness.

对经验开放性的多重测量与正面、负面和无组织的精神分裂的简短问卷的关联

摘要。精神分裂症谱系障碍的易感性表现为一系列临床和亚临床症状以及称为精神分裂症的损伤。分裂型是一个多维结构，具有正面、负面和杂乱无章的维度。开放体验为探索多维分裂型提供了有用的人格领域。本研究在 2,236 名成年人样本中使用多维精神分裂量表（MSS-B）检查了开放性的因子结构及其与精神分裂症的关系。阳性分裂型与开放性升高广泛相关，而阴性分裂型通常与开放性降低有关。15个开放方面的主成分分析复制了开放的四因素结构，包括幻想/感觉、怪癖、非传统主义和想法因素。所有三个分裂维度都与偏心有关。积极的分裂型与幻想/感觉有关，而消极的分裂型与幻想/感觉呈负相关。结果支持 MSS-B 的结构效度、在检查分裂症时使用替代开放性措施以及分裂症和开放性的多维结构。
