This article aimed to test the social identity mediation model of procedural justice on group-oriented behaviors and self-esteem. The model consists of two processes involving perceived procedural justice and behaviors or self-esteem: the mediate process of social identity and the direct process of procedural justice. Three surveys concerning national politics were conducted with a sample of 1000-1180 citizens to test the model. Study 1 revealed that procedural justice enhances the justice perceivers' pride as a Japanese citizen and that the pride was linked to an assertive attitude toward the nation. Their self-esteem trait measured in Rosenberg (1965) was also associated with pride. Study 2 tested the model on supportive behaviors for authority and for members. For members, SEMs revealed that pride mediated between procedural justice and helping behaviors. On the other hand, the supportive behaviors for authority were enhanced by both the pride mediate process and the direct process of procedural justice. Study 2 also revealed that people's collective self-esteem (Luhtanen & Crocker, 1992) was linked to procedural justice by both processes. Study 3 proposed a concept of "relational self-esteem" and developed a new scale for its measurement. A CFA revealed that relational self-esteem consists of three elements: importance of relational existence, relational happiness, and social self-acceptance. Testing the model on relational self-esteem found two mediate processes, affective-pride mediation and respect mediation, but did not reveal any direct process. This result suggested that relational self-esteem is an effective indicator for self-value of procedural justice. The results of these studies indicated that social identity which is connected to procedural justice enhances people's positive self-image, and simultaneously motivates them to act on the behalf of others. Procedural justice could make people internalize the link to society through the social identification processes.
