Objective To explore the relationship between different dimensions and subtypes of workplace bullying and suicide among nurses, so as to construct intervention methods to reduce suicide risk.Methods A total of 3,026 nurses from four tertiary hospitals in Shandong province were recruited by convenience sampling method.The Negative Acts Questionnaire Revised and Suicidal Behaviors Questionnaire Revised were used to assess the workplace bullying and suicide risk of nurses.Results The total scores of workplace bullying and suicide were （31.17±14.48） points and （4.16±2.22） points, respectively.The total score of workplace bullying and the dimension of organizational injustice were positively correlated with suicide risk (both P＜0.05).Five subtypes of workplace bullying were identified including "low bullying type" （52.25%）, "moderate bullying type" （9.35%）, "high bullying type" （17.02%）, "overloaded type" （10.67%）, and "mismatch type" （10.71%）.In comparison to the "low bullying type", individuals identified as the "moderate bullying type" （OR=6.096）, "high bullying type" （OR=5.832）, "overloaded type" （OR=3.668） and "mismatch type" （OR=3.391） demonstrated an increased probability of reporting suicide.Conclusion There are diffe-rent categories of workplace bullying experienced by nurses.The correlation between workplace bullying and suicide among nurses underscores the importance for hospital managers to focus on cultivating a supportive work environment for nurses and actively work towards minimizing instances of workplace bullying.
