道德基础理论认为，人类至少进化出了5种道德基础：公正、关爱、忠诚、权威和圣洁。人们对各道德基础的看重程度不同，表现出不同的道德观。在新冠肺炎疫情暴发的背景下，本研究采用道德基础问卷，分别于新冠肺炎疫情暴发前（2017年11月26日—12月7日）、暴发期间（2020年2月29日—4月30日）和暴发后（2020年7月14—16日）多次收集中国大学生的道德观数据，旨在考察疫情前后大学生道德观的变化趋势。研究发现：疫情暴发期间，大学生对个体性（公正和关爱）和群体性道德基础（忠诚、权威和圣洁）的看重程度均显著高于疫情暴发前；疫情基本得到控制后，大学生对个体性和群体性道德基础的总体看重程度并未立即出现明显回落或进一步上升。研究结果说明，与2017年相比，大学生的道德重视程度在疫情发生后有明显上升，其背后的原因需进一步探究。
Moral foundation theory deemes that human groups have constructed moral virtues, narratives and institutions based on at least five innate psychological foundations:care, fairness, loyalty, authority and sanctity. Moral values are reflected in the degree of endorsement of each moral foundation. In the context of the COVID-19 in China, to examine the changing trend of college students' moral values, the study used a moral foundations questionnaire to survey two groups of Chinese college students before (November 26-December 7, 2017), during (February 29-April 30, 2020) and after the COVID-19 outbreak (July 14-16, 2020). The results show that college students attached more importance to both individual foundations (care and fairness) and collective foundations (loyalty, authority and sanctity) after the COVID-19 outbreak than before. When the epidemic was basically under control, the college students'overall endorsement of individual and collective foundations did not immediately fall or rise significantly. The results suggest that compared with 2017, college students' endorsement of moral foundations had increased significantly after the outbreak of the epidemic; the reasons behind it need to be further explored.
