Psychological reactions to pandemics and their constraints depend heavily on personality. Although perfectionism is consistently associated to depression, anxiety and stress, its role in the pandemics' psychological impact has not been yet empirically studied. Our aim was to analyze the role of perfectionism in psychological distress during the pandemic of COVID-19, testing whether it is mediated by fear of COVID-19 and repetitive negative thinking/RNT. Participants (N = 413 adults; 269.2% women) were recruited from September until December 2020, via social networks. They completed self-report validated questionnaires to evaluate perfectionism dimensions (self-critical, rigid and narcissistic perfectionism), fear of COVID-19, RNT and psychological distress (sum of anxiety, depression and stress symptoms). As women had significantly higher levels of self-critical perfectionism, RNT, fear of COVID-19 and psychological distress, gender was controlled in mediation analysis. The three perfectionism dimensions correlated with RNT, fear of COVID-19 and psychological distress. The effect of self-critical perfectionism on psychological distress was partially mediated by fear of COVID-19 and RNT whereas the effect of rigid and narcissistic perfectionism was fully mediated. Perfectionism influences emotional and cognitive responses to the COVID-19 and therefore should be considered both in the prevention and psychological consequences of the pandemic.

对流行病的心理反应及其限制在很大程度上取决于个性。尽管完美主义一直与抑郁、焦虑和压力有关，但其在流行病心理影响中的作用尚未得到实证研究。我们的目的是分析完美主义在 COVID-19 大流行期间在心理困扰中的作用，测试它是否是由对 COVID-19 的恐惧和重复的消极思维/RNT 介导的。参与者（N = 413 名成人；269.2% 为女性）是在 2020 年 9 月至 2020 年 12 月期间通过社交网络招募的。他们完成了自我报告验证问卷，以评估完美主义维度（自我批评、僵化和自恋的完美主义）、对 COVID-19 的恐惧、RNT 和心理困扰（焦虑、抑郁和压力症状的总和）。由于女性具有更高水平的自我批评完美主义、RNT、对 COVID-19 的恐惧和心理困扰，因此在调解分析中控制了性别。这三个完美主义维度与 RNT、对 COVID-19 的恐惧和心理困扰相关。自我批评完美主义对心理困扰的影响部分由对 COVID-19 和 RNT 的恐惧所调节，而刻板和自恋的完美主义的影响则完全被调节。完美主义会影响对 COVID-19 的情绪和认知反应，因此在大流行的预防和心理后果中都应予以考虑。对 COVID-19 的恐惧和心理困扰。自我批评完美主义对心理困扰的影响部分由对 COVID-19 和 RNT 的恐惧所调节，而刻板和自恋的完美主义的影响则完全被调节。完美主义会影响对 COVID-19 的情绪和认知反应，因此在大流行的预防和心理后果中都应予以考虑。对 COVID-19 的恐惧和心理困扰。自我批评完美主义对心理困扰的影响部分由对 COVID-19 和 RNT 的恐惧所调节，而刻板和自恋的完美主义的影响则完全被调节。完美主义会影响对 COVID-19 的情绪和认知反应，因此在大流行的预防和心理后果中都应予以考虑。
