PURPOSE: This study was to assess the prevalence of workplace bullying and the relationship workplace bullying to self-esteem and turnover intention among clinical nurses. METHODS: The subjects were 223 clinical nurses at 3 small and medium-sized hospitals in K and B cities. The data were collected from February 1st throughout 28th, 2013. The collected data were analyzed using the SAS program through the frequency, percentage, mean, and Pearson's correlation coefficients. RESULTS: The rate of self-reported bullying in the nursing workplace was 24.6% of respondents. There was a negative correlation between workplace bullying and self-esteem (r=-.39, p<.001). Also there was a positive correlation between workplace bullying and turnover intention (r=.14, p=.031). CONCLUSION: Prevalence of self-reported bullying is high among small and medium-sized hospitals and is clearly associated with lower levels of self-esteem and higher levels of turnover intention. Therefore, an organizational nursing management program as a monitoring regularly the psychosocial work environment and policies and procedures to prevent and manage workplace bullying is strongly recommended for the promotion of self-esteem and reducing the nurse's intention to leave the organization.
