Purpose: The aim of this study was to evaluate the effectiveness of interventions for workplace bullying among
nurses. Methods: First, risk factors of workplace bullying were categorized in order to create analysis criteria. A search
of 8 databases, and manual searching resulted in the identification of 3,096 relevant articles. Three of the authors
did article selection, data extraction, and quality assessment using the Risk of Bias (RoB) and the Risk of Bias for
Nonrandomized studies (ROBANS). Results: Interventions in workplace bullying were classified as individual, interactions,
and organizational approach. Twelve intervention studies (10 individual interventions, 1 team approach, 1
multi-level approach) were selected. Four of the individual interventions decreased bullying, but three had no effect.
One multi-level intervention reported that bullying did not occur. Individual interventions improved bullying awareness
in four articles, decreased turnover intention in two articles, and increased skill and knowledge of bullying management
in five articles. One team approach increased nurse interactions and group cohesion. The quality of selected
articles was low overall. Conclusion: Individual interventions have a possibility to improve awareness and knowledge
about bullying, but there is a lack of evidence on preventing bullying. Further research is required on multi-levels
interventions with well-designed controlled trials.
