The current study utilizes the current COVID-19 pandemic to highlight the importance of accounting for the influence of external political and economic factors in personality public health research. We investigated the extent to which systemic factors modify the relationship between personality and pandemic response. Results shed doubt on the cross-cultural generalizability of common Big Five factor models. Individual differences only predicted government compliance in autocratic countries and in countries with income inequality. Personality was only predictive of mental health outcomes under conditions of state fragility. Our ability to use individual differences to understand policy-relevant outcomes changes based on environmental factors and must be assessed on a trait-by-trait basis, thus supporting the inclusion of systemic political and economic factors in individual differences models.

本研究利用当前的COVID-19大流行来强调人格公共卫生研究中考虑外部政治和经济因素影响的重要性。我们调查了系统性因素在多大程度上改变了人格与大流行反应之间的关系。结果使人们对常见的“五大”因素模型的跨文化概括性表示怀疑。个体差异仅预测了专制国家和收入不平等国家的政府合规情况。人格只能预测国家脆弱状态下的心理健康结果。我们利用个人差异来理解基于环境因素的与政策相关的结果变化的能力，并且必须在逐个特征的基础上进行评估，
