This paper aims to investigate the strength of the association between victimisation by peers at age 13 years and depression at 18 years using a prospective cohort study of 6719 participants.
When using observational data it is impossible to be certain that associations are causal. However, the results of the study are consistent with the hypothesis that victimisation by peers in adolescence is associated with an increase in the risk of developing depression as an adult.
