Abstract：This study examined loneliness as a mediator and perceived school climate as a moderator in the relationship between peer ostracism and adolescent suicide behavior. The participants of this study were 1218 students from 4 primary schools and 4 middle schools in Sichuan Province. Participants were asked to provide ratings for their ostracism experiences at school, the UCLA Loneliness Scale, Delaware School Climate Survey, the suicide behavior items from Health-Risk Behavior Inventory and some other information. The results showed that: (1) Peer ostracism was significantly and positively related to adolescent suicide behavior. (2) Peer ostracism was found to be significantly and positively related to loneliness; in turn, loneliness was significantly and positively related to adolescent suicide behavior. Taken together, loneliness mediated the relationship between peer ostracism and adolescent suicide behavior. (3) Perceived school climate moderated the relationship between loneliness and adolescent suicide behavior. Loneliness has a significant effect on adolescent suicide behavior only when perceived school climate is low. (4) Perceived school climate further moderated the indirect relationship between peer ostracism and adolescent suicide behavior through loneliness. The indirect effect of perceived peer ostracism on adolescent suicide behavior through loneliness is significant only when perceived school climate is low. This study advances understanding of the peer ostracism-adolescent suicide behavior relationship by identifying loneliness as an explanatory mechanism and perceived school climate as a boundary condition that peer ostracism might induce adolescent suicide behavior.
