Purpose: The purpose of this study was to examine the effects of a violence coping program (VCP) based on Polk’s middle-range theory of resilienceon nursing competency, resilience, burnout, and the ability to cope with violence in nurses working in emergency rooms. Methods: A quasi-experimental study, with a nonequivalent control group and a pretest-posttest design, was conducted. Participants were 36 nurses whoworked in emergency rooms and had experienced violence; 18 nurses from D hospital and 18 nurses from C hospital were assigned to the experimentaland control groups, respectively. The experimental group received the VCP twice per week for 8 weeks. Results: Levels of resilience,F =59.41, pqqqlt;.001, active coping behavior, c2=33.09, pqqqlt;.001, and nursing competency, F =59.41 pqqqlt;.001, increased significantly and levels of passivecoping behavior, c2=22.92, pqqqlt;.001, and burnout, F =52.74, pqqqlt;.001, decreased significantly in the experimental group. Conclusion: The results suggestthat the VCP could be an effective strategy for reducing burnout and improving resilience, active coping behavior, and nursing competency. Therefore, it would be a useful intervention for improving the quality of nursing care provided in emergency rooms.
