The Effect of Peer Victimization During Adolescence on Depression and Gender Differences: A Systematic Review and Meta-analysis

Abstract

Peer victimization during adolescence has a detrimental impact on the mental health of victims throughout their lives. However, it remains unclear whether these effects are gender-specific. The present study conducted a systematic review to examine the effects of peer victimization on depression status, explore potential sources of heterogeneity, and investigate gender differences in these effects. We systematically searched four electronic databases (Web of Science, PubMed, Embase, and CNKI) for relevant articles that published as far as July 2022.

Meta-analysis was performed, using fixed effects models and random effects models, to evaluate the association between each exposure and the outcome. A meta-analysis of 27 studies revealed that peer victimization during adolescence was significantly associated with higher risks of depression (OR = 2.79, 95% CI [2.43, 3.21], p
