Abstract

Bullying is shown to be associated with adverse outcomes in cross-sectional studies, but only a few studies have prospectively examined the effects of childhood bullying on adult outcomes. Our Series paper focuses on prospective longitudinal studies that used large, population-based, community samples analysed through quantitative methods and published between 1960 and 2015. We describe the results of childhood bullying in adulthood in three of the most burdensome areas: psychopathology, suicidality, and criminality. We note that the different groups involved (ie, victims, bullies, and bully-victims) are at risk of difficulties later in life, but their risk profiles differ and the contributions are probably not independent. Controlling for confounders reduces the risk and sometimes eliminates it. Victims are at a high risk of internalising disorders. Bullies seem to be at risk of later externalising disorders and criminality, mainly violent crime and illicit drug misuse. Bully-victims seem to be at risk of internalising disorders, externalising disorders, and criminality, but not all studies examined bully-victims as a separate group. Boys and girls differ in their long-term outcomes. A dose effect exists in which frequent bullying involvement in childhood is most strongly associated with adult adversities. Future studies need to control for additional factors (including genetic, psychosocial, and environmental) to account for the mechanisms behind the reported longitudinal associations.

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.
