BACKGROUND: Given the nature of the health profession, medical errors are considered a common problem. Nursing students are inevitably likely to make medical errors due to the lack of adequate and safe learning environments during their clinical practice. AIM: We aimed to investigate the relationship between the tendency to make medical errors and the level of mindfulness of senior nursing students. METHODS: Data were collected using the Malpractice Trend Scale (MTS) and the Mindful Attention Awareness Scale (MAAS). This study was reported following STROBE. RESULTS: The students' MAAS total score mean was 62.96 ± 1.64. The MTS total score mean was 79.91 ± 1.25. According to Pearson correlation analysis, there was a weak, positive (r = 0.194) and statistically insignificant (p >
0.05) relationship between the total scores of MTS and MAAS. CONCLUSIONS: It was concluded that as the students' mindfulness levels increase, their tendency to make medical error decreases, but this result is not statistically significant.
