目的:人格,情感,嗅觉在边缘系统结构中表现出部分解剖重叠,建立人格之间的潜在机制,情感障碍,和嗅觉相关的方面。因此,这项研究旨在调查大五人格特质之间的关联,述情障碍,焦虑症状,和气味意识。
方法:本研究共招募了863名大学参与者。所有参与者都完成了中国五大人格量表-15,气味意识量表(OAS),多伦多述情障碍量表-20和广泛性焦虑症筛选器-7。采用结构方程模型来检验假设的中介模型。
结果:研究结果揭示了大五人格特质维度之间的大部分显著相互关联,述情障碍,焦虑症状,和OAS(|r|=0.072-0.567,p<0.05)。述情障碍和焦虑症状在神经质和OAS之间表现出一系列调解作用(95CI[0.001,0.014]),责任心和美洲国家组织(95CI[-0.008,-0.001]),和外向性和OAS(95CI[-0.006,-0.001])。焦虑症状介导了同意性与OAS(95CI[-0.023,-0.001])以及开放性与OAS(95CI[0.004,0.024])之间的关系。
结论:述情障碍和焦虑症状在大五人格特质和气味意识之间的中介作用支持人格之间存在一定程度的关联。情感,和嗅觉,具有边缘系统结构的潜在作用。这增强了我们对人格的理解,情感,和嗅觉,并为未来情感障碍和嗅觉功能障碍的干预措施提供见解。
OBJECTIVE: Personality, emotions, and olfaction exhibit partial anatomical overlap in the limbic system structure, establishing potential mechanisms between personality, affective disorders, and olfactory-related aspects. Thus, this study aims to investigate the associations among the Big Five personality traits, alexithymia, anxiety symptoms, and odor awareness.
METHODS: A total of 863 college participants were recruited for this study. All participants completed the Chinese Big Five Personality Inventory-15, the Odor Awareness Scale (OAS), the Toronto Alexithymia Scale-20, and the Generalized Anxiety Disorder Screener-7. Structural equation modeling was employed to examine the hypothesized mediated model.
RESULTS: The findings revealed the majority of significant intercorrelations among the dimensions of the Big Five personality traits, alexithymia, anxiety symptoms, and OAS (|r| = 0.072-0.567, p < 0.05). Alexithymia and anxiety symptoms exhibited a serial mediation effect between neuroticism and OAS (95%CI[0.001, 0.014]), conscientiousness and OAS (95%CI[-0.008, -0.001]), and extraversion and OAS (95%CI[-0.006, -0.001]). Anxiety symptoms mediated the relationship between agreeableness and OAS (95%CI[-0.023, -0.001]) and between openness and OAS (95%CI [0.004, 0.024]).
CONCLUSIONS: The mediating roles of alexithymia and anxiety symptoms between the Big Five personality traits and odor awareness support the idea of a certain level of association among personality, emotions, and olfaction, with the underlying role of the limbic system structure. This enhances our understanding of personality, emotions, and olfaction and provides insights for future intervention measures for affective disorders and olfactory dysfunctions.
