Purpose: The purposes of this study were to explore nurse` bullying experiences according to demographic characteristics and to identify effects of workplace bullying and job stress on turnover intention in hospital nurses. Methods: One hundred sixty-one graduate students working as nurses were recruited. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression with PASW 18.0. Results: Results show that 23.0% of the nurses interviewed had experienced bullying in the workplace within the last six months and 19.4% had been bullied during the entire employment period. Bullying perpetrators included nurses (52.9%), physicians (23.0%), and patients (17.8%). Bully nurses consisted of senior nurses (63.0%), managers or supervisors (29.6%), colleagues (3.7%), and junior nurses (3.7%). Job turnover intention in hospital nurses was significantly correlated with workplace bullying (r=.20, p=.012) and job stress (r=.37, p<.001). The most significant predictors influencing the turnover intention of hospital nurses were job stress, age, and bullying in total career and these factors accounted for 21.0% of the variance. Conclusion: Job stress and bullying significantly influence turnover intention. Therefore, educational programs should be developed and implemented to prevent workplace bullying.
