“Doomsday prepping” is a phenomenon which involves preparing for feared societal collapse by stockpiling resources and readying for self-sufficiency. While doomsday prepping has traditionally been reported in the context of extremists, during the COVID-19 pandemic, excessive stockpiling leading to supply shortages has been reported globally. It is unclear what psychological or demographic factors are associated with this stockpiling. This study investigated doomsday prepping beliefs and behaviors in relation to COVID-19 proximity, demographics, coping strategies, psychopathology, intolerance of uncertainty (IU), and personality in 384 participants (249 female) in an online study. Participants completed a number of questionnaires including the Post-Apocalyptic and Doomsday Prepping Beliefs Scale and a scale designed for the current study to measure prepping in the context of COVID-19. These were analyzed using ANOVAs, correlational, and mediation analyses to examine relationships between psychometric variables and stockpiling. Prepping beliefs and behaviors were higher in males than females and positively associated with anxiety, obsessive-compulsive symptoms, IU, and traditional masculinity traits. Older age, male gender, obsessive-compulsive symptoms, and traditional masculinity predicted unique variance in prepping. The relationship between gender and stockpiling was mediated by social learning (witnessing other people panic buying) and the perceived threat of COVID-19 (doomsday interpretations) while proximity and personal vulnerability to COVID-19 were non-significant. Results indicate that panic buying was influenced more by witnessing others stockpiling, personality, and catastrophic thinking rather than by proximity to danger. Education could target these factors in ongoing waves of the pandemic or future catastrophes.

“世界末日准备”是一种现象，涉及通过储存资源和为自给自足做好准备，以应对可能发生的社会崩溃。传统上在极端主义者的背景下报道了世界末日的准备工作，但在COVID-19大流行期间，全球范围内都报告了过多的库存导致供应短缺。目前尚不清楚该储存与哪些心理或人口统计学因素有关。这项研究在线调查了384名参与者（249名女性）中与COVID-19亲近感，人口统计学，应对策略，心理病理学，不确定性不耐受（IU）和性格有关的世界末日准备信念和行为。参与者完成了许多问卷调查，包括世界末日后和世界末日的预备信念量表以及为当前研究设计的用于在COVID-19背景下测量预备量表的量表。使用方差分析，相关性和中介分析对这些变量进行了分析，以检查心理计量变量与库存之间的关系。男性的准备信念和行为高于女性，并且与焦虑，强迫症，IU和传统男性气质特征呈正相关。老年人，男性，强迫症和传统男性气质预示着准备过程的独特差异。性别与库存之间的关系是由社会学习（见证其他人的恐慌购买）和认为的COVID-19威胁（末日解释）介导的，而亲近性和个人对COVID-19的脆弱性则不重要。结果表明，恐慌性购买更多地是受到目击者的库存，性格和灾难性思维的影响，而不是接近危险。教育可以在持续的大流行浪潮或未来的灾难中针对这些因素。
