Abstract: The purpose of this study was to identify the relationship among type D personality, stress, health promotion behaviors and eating tendency in nursing students. The study was conducted on 209 nursing students in J Province and from between December 1st and 15th 2015. The data was analyzed using a t-test, x², Pearson’s correlation using SPSS 21. About 23.4% of participants were classified as type D personality group. The subjects with type D personality had lower subjective health status than subjects who did not. Those with type D personality had higher stress level and lower health promotion behavior level than those who did not. There were positive correlations between type D personality and the level of stress (r = 2.97, p<0.001) and negative correlations between type D personality and health promotion behavior (r = -0.269, p<0.001). Based on these findings, programs that develop of stress management and health promotion behaviors are necessary for college nursing students and research is needed on factors affecting type D personality.
