This study investigated the prospective links between three forms of peer adversities (i.e., victimization, rejection, and lack of reciprocated friendships) and children's perceptions of themselves and of their peers. The sample consisted of 212 children (107 boys and 105 girls, 11–13 years) recruited from four primary schools and followed up for a period of one year. The results showed that a negative self-perception was a risk factor for the development of all forms of peer adversities. Of the three forms of peer adversities assessed, victimization and rejection had an influence on children's peer perceptions. None of the peer adversities predicted changes in self-perceptions. The results partially support a transactional model between children and their environments.
