PURPOSE: The purpose of this study was to identify relationships among self-esteem, social support, nursing organizational culture, experience of workplace bullying, and the consequences of workplace bullying in hospital nurses, and then to provide basic information for developing workplace bullying prevention programs. METHODS: Participants were 122 hospital nurses from three general hospitals. Data collection was done during April and May 2015. Data were collected using self-report questionnaires which were used to identify participants' characteristics, self-esteem, social support, nursing organizational culture, and workplace bullying. RESULTS: Approximately one quarter of the nurses had experienced workplace bullying in the past six months. Hierarchical regression analysis showed that experience of workplace bullying (β=.45) and self-esteem (β=-.31) explained 53.3% of the variance in consequences of workplace bullying. CONCLUSION: Based on the findings that experiencing workplace bullying and having a low self-esteem were likely to increase workplace bullying in hospital nurses, there is a need to develop prevention and intervention programs on avoiding or dealing with workplace bullying.
