Objectives: The aim of this study is to determine the effect of conflict resolution training, on the nursing student's conflict resolution skills. Pre-test and post-test control group research was conducted as a semi-experimental model. Methods: At the and the sample group of the study comprised of 105 students: n= 62 for experimental group with a low score mean (110 and below) and n= 43 for control group with the same total score. Conflict Resolution Training was given to the experimental group between October, 4, 2010 and December, 17, 2010. Posttests (an student description form and the conflict resolution scale) were conducted on December, 24, 2010, a week after training ended. No intervention was conducted on the control group, and posttests (an student description form and the conflict resolution scale) were conducted on December, 23, 2010. Results: According to the pretest score means of experimental and control group students obtained from the conflict resolution scale, there was no statistically significant difference between the overall total score and the sub-scales (p>0.05). According to the posttest score means of experimental and control group students obtained from the conflict resolution scale, there was no statistically significant difference between the total score of "resting skills" and "anger management" sub-scale (p>0.05); however, there was a statistically significant difference between the overall score mean, and the score means of the other sub-scales (p<0.05). The overall score mean of conflict resolution scale for students in the experimental group before conflict resolution training was 85.03+10.57, while after conflict resolution training this average increased to 101.48 +/- 14.24. There was a statistically significant difference between the pretest score mean and posttest score mean for students in the experimental group (p<0.05). Conclusion: Study result, concluded that conflict resolution training, increased conflict resolution skills of nursing students that participated in the training program.
