The study aimed to explore the roles of familys objective social status of freshmen, subjective social status and the poor students label in belief in a just world for freshmen. This study investigated 1060 freshmen from central, eastern and western China respectively and adopted correlation analysis and a moderated mediation model for data analysis. The results showed that: (1) Familys objective social status was significantly positively correlated with subjective social status and belief in a just world; (2) Subjective social status was significantly positively correlated with belief in a just world; (3) Subjective social status completely mediated the influence of familys objective social status on belief in a just world; (4) Poor students label moderated the mediation role of subjective social status.
Specifically, among these freshmen with similar familys objective social status, students with poor labels had lower subjective social status and lower belief in a just world. The results
demonstrated that the improvement of subjective social status had positive effect on freshmens belief in a just world. However, poor students labels negative effect should be carefully addressed in future educational practice.
