Mediator of school belongingness and moderator of migration status in the relationship between peer victimization and depression among Chinese children: A multi-group structural equation modeling approach

Abstract

Peer victimization is a widespread threat to children's mental health. However, existing literature has yet to thoroughly investigate the mediators and moderators underlying the link between peer victimization and depression of Chinese children. Using a sample of school-aged children recruited through a multi-stage cluster random sampling in Southwest China (N = 1322), this study examined the mediating role of school belongingness between overt/relational victimization and children's depressive symptoms. In order to test the moderator of migration status, multi-group structural equation modeling (SEM) was adopted to investigate whether the paths in the mediation model were significantly different across migrant and non-migrant groups. Results indicated that overt and relational victimization had a direct impact on depression. School belongingness mediated the link between overt victimization and depression, but not the link between relational victimization and depression. Furthermore, migration status moderated the direct associations between peer victimization and depression. Specifically, the effect of overt victimization on depression was significant for migrant children but not for local children. By contrast, the effect of relational victimization on depression was significant for local children but not for migrant children. The contributions and implications of this study were discussed.
