This study explained why interpersonal injustice enacted by representatives of an authority might undermine perceived legitimacy of the actual authority. We built a moderated mediation model in which institutional trust was the mediator, and informational justice was the moderator, in the relationship between interpersonal injustice and perceived legitimacy of authority. Study 1 showed that interpersonal injustice negatively influenced perceived legitimacy of authority. Study 2 indicated that institutional trust was a significant mediator of the relationship between interpersonal injustice and perceived legitimacy of authority. Study 3 indicated that institutional trust was a significant mediator of the relationship between interpersonal injustice and perceived legitimacy of authority when an explanation was absent, whereas it was not significant when explanation was given. These findings contribute to the literature by identifying components that shape the psychological process of forming legitimacy perceptions of authority.

人际间的不公正与权威的合法性：制度信任与信息正义的作用

这项研究解释了为什么一个机构代表所实施的人际不公正可能会破坏实际机构的合法性。我们建立了人与人之间的不公正与权威的合法性之间关系的调解调解模型，其中机构信任是调解者，信息正义是调解人。研究1表明人际间的不公正对权威的合法性产生了负面影响。研究2表明，机构信任是人际间不公正与权威合法性之间关系的重要中介。研究3表明，缺乏解释时，制度上的信任是人际间不公正与权威合法性之间关系的重要中介，而给出解释时并不重要。这些发现通过确定构成权威合法性观念的心理过程的要素，为文献做出了贡献。
