The study of bullying in adolescence has received increased attention over the past several decades. A growing body of research highlights the role of forgiveness and its association with aggression. In this article, we systematically review published studies on the association among online and traditional bullying and forgiveness in adolescents. Systematic searches were conducted in PsycINFO, MEDLINE, PsycArticles, and Scopus databases. From a total of 1,093 studies, 637 were nonduplicated studies and 18 were eventually included. Together, these studies provided evidence that forgiveness and bullying behaviors are negatively related: Adolescents with higher forgiveness levels bully less. Similarly, forgiveness is negatively related to victimization: Adolescents with higher forgiveness show less victimization. Unforgiveness was positively related to traditional and online bullying. This relationship appears to be consistent beyond types of bullying, certain background characteristics, and forgiveness measures. These findings are discussed, and clinical implications and guidelines for future research are presented.
