This study investigated the association between personality traits and food stockpiling for disasters in predicted high-risk areas of food shortages due to the Nankai Trough Earthquake. This survey was conducted between December 18 and 20, 2019, using a web-based questionnaire. The participants were 1,200 individuals registered with an online survey company. This study analyzed the association between the Big Five personality traits and food stockpiling status (n = 1192). The Big Five personality traits assess five basic dimensions of personality (i.e., extraversion, conscientiousness, agreeableness, neuroticism, and openness). To measure theses personality traits, we used the Japanese version of the Ten-Item Personality Inventory (TIPI-J). The Mann-Whitney test and a multivariable logistic regression analysis revealed that none of the Big Five personality traits were significantly associated with having or not having stockpile food. However, interestingly, considering the stages of behavior change regarding stockpiling, high extraversion was significantly positively related to initiating stockpiling. Moreover, high neuroticism was significantly positively related to interrupted stockpiling. Therefore, it is crucial to focus on personality traits (especially low extraversion and high neuroticism) to promote food stockpiling for disasters.
这项研究调查了人格特质与食物囤积之间的关系，研究对象是预计因南凯槽地震导致食物短缺的高危地区的人们。这项调查于 2019 年 12 月 18 日至 20 日通过网络问卷进行。参与者是在一家在线调查公司注册的 1200 人。本研究分析了大五人格特质与食物囤积状况之间的关系（n=1192）。大五人格特质评估了人格的五个基本维度（即外向性、尽责性、宜人性、神经质和开放性）。为了测量这些人格特质，我们使用了日本版的 10 项人格量表（TIPI-J）。Mann-Whitney 检验和多变量逻辑回归分析表明，大五人格特质均与是否囤积食物无关。然而，有趣的是，考虑到囤积行为的变化阶段，高外向性与开始囤积食物呈显著正相关。此外，高神经质与囤积中断呈显著正相关。因此，关注人格特质（尤其是低外向性和高神经质）以促进灾害期间的食物囤积是至关重要的。
