Protective factors against bullying and cyberbullying: A systematic review of meta-analyses

Zych, Izabela, Farrington, David P., Ttofi, Maria M.·2019·Aggression and Violent Behavior

Abstract

Abstract Bullying and cyberbullying are damaging aggressive behaviors in which some children and adolescents intentionally inflict frequent and long term harm on peers who become victimized. The number of studies on bullying is high and a lot of knowledge has already been gathered. Nevertheless, there are still many gaps in knowledge that need to be addressed. Research on protective factors and effective interventions is still in its relatively early stages. This systematic review of meta-analyses on protective factors against bullying and cyberbullying was conducted to synthesize knowledge and discover the most important community, school, family, peer and individual protective factors. After systematic searches and the application of inclusion and exclusion criteria, 18 meta-analyses with 128 effect sizes were included and analyzed. Forest plots were constructed and median effect sizes were calculated for each group of protective factors. Self-oriented personal competencies were the strongest protector against victimization. Low frequency of technology use protected from involvement in cyberbullying. Good academic performance and other-oriented social competencies were the strongest protective factors against perpetration. Positive peer interaction was the strongest protective factor against being a bully/victim. These findings can be useful to improve anti-bullying programs, policy and practice.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
