With rates of vegetarianism and veganism (i.e., vegnism) rising around the world, a growing body of research has begun to explore psychological characteristics that distinguish vegetarians and vegans from omnivores. However, relatively few studies have examined how vegnism is related to differences in basic personality traits such as the "Big Five", with those that have tending to yield conflicting results. Moreover, none of these studies have examined personality at the lower levels of the personality trait hierarchy (i.e., aspects and facets of the Big Five). Thus, we sought to clarify how personality traits are related to vegnism. In Study 1, comprising two samples (S1a: N = 797, S1b: N = 1534), participants were categorised as Vegn vs Restricted-omnivore vs Omnivore, and completed personality questionnaires at the domain and aspect levels of the Big Five. In Study 2, participants (N = 562) completed both categorical and continuous measures of vegnism, along with personality questionnaires at the domain, aspect, and facet levels. Across both studies, we found that people who scored higher on traits within the openness/intellect and agreeableness domains most consistently reported higher levels of vegnism. Patterns in the data also suggested that the relation between personality and vegnism might depend on the way vegnism is measured. Theoretical and practical implications of these findings are discussed.
随着素食主义和纯素食主义（即 vegnism）在全球范围内的兴起，越来越多的研究开始探索将素食主义者和纯素食主义者与杂食者区分开来的心理特征。然而，相对较少的研究探讨了 vegnism 如何与基本人格特质（如“大五”）的差异相关，而那些研究往往得出相互矛盾的结果。此外，这些研究中没有一项研究考察了人格特质层次结构的较低层次（即“大五”的各个方面和特质）与 vegnism 的关系。因此，我们试图阐明人格特质与 vegnism 的关系。在研究 1 中，包括两个样本（S1a：N=797，S1b：N=1534），参与者被归类为 Vegn 与限制杂食者与杂食者，并且在“大五”的领域和方面水平上完成了人格问卷。在研究 2 中，参与者（N=562）完成了 vegnism 的分类和连续测量，以及“大五”的领域、方面和特质水平的人格问卷。在这两项研究中，我们发现，在开放性/智力和宜人性领域得分较高的人最一致地报告了更高水平的 vegnism。数据中的模式还表明，人格与 vegnism 之间的关系可能取决于 veg*nism 的测量方式。讨论了这些发现的理论和实践意义。
