The purpose of this study was to investigate the relationship between personality traits and hoarding behavior during the coronavirus disease (COVID-19) pandemic. An online survey was conducted among 530 Japanese adults (274 women; M_age = 44.26, SD_age = 8.43) who were living in Tokyo when a state of emergency was declared. Personality traits were assessed using measures of the Big Five personality traits and dispositional greed. They also responded to measures of tendencies to hoard essential and countermeasure products during the COVID-19 pandemic. Correlation analysis revealed that Extraversion, Neuroticism, Openness, and dispositional greed were positively associated with hoarding behavior. Multiple regression analysis revealed that individuals with high Agreeableness, Neuroticism, Openness, and dispositional greed tended to hoard products. The present findings suggest that personality traits account for behavioral responses to the COVID-19 pandemic in Japan. The emergent relationship between hoarding behavior and each personality trait is discussed in relation to the existing literature.

本研究的目的是调查冠状病毒病 (COVID-19) 大流行期间人格特质与囤积行为之间的关系。对 530 名日本成年人（274 名女性；M_年龄 = 44.26，SD_年龄 = 8.43) 在宣布紧急状态时居住在东京的人。使用大五人格特质和性格贪婪的措施评估人格特质。他们还对 COVID-19 大流行期间囤积必需品和对策产品的趋势措施做出了回应。相关分析表明，外向性、神经质、开放性和贪婪性格与囤积行为呈正相关。多元回归分析显示，具有高宜人性、神经质、开放性和贪婪倾向的个体倾向于囤积产品。目前的研究结果表明，人格特质可以解释日本对 COVID-19 大流行的行为反应。囤积行为与每个人格特质之间的新兴关系是根据现有文献进行讨论的。
