Abstract: A survey of 417 college students in a western province was conducted by using the scales of belief in a just world, self-esteem and self-acceptance to explore the relations among the belief in a just world, self-esteem and self-acceptance of college students. The results show that there are significant differences between the belief in a just word and self-acceptance among different grades of college students; there are significant positive correlations among belief in a just world, self-esteem and self-acceptance; belief in a just world and self-esteem can significantly predict self-acceptance; self-esteem has partial mediation effect between the belief in a just world and self-acceptance. It is concluded that the belief in a just world can either directly influence self-acceptance, or indirectly influence self-acceptance through self-esteem.
