Results: 51/5% of female students, 82/9% were single, 53% were non-native and their mean age was 23 years. The results showed that the mean and standard deviation of students' life satisfaction was 15/09±4/29, which was higher than the average value, and the mean self-efficacy score was 56/82 ±6/67 that was at a moderate level.  There was also a significant positive correlation between self-efficacy and life satisfaction (p<0.001، r=0.4).

Conclusion : Findings showed that self-efficacy was related to life satisfaction in nursing students. In other words, as self-efficacy increases, life satisfaction increases. Therefore, it is suggested that measures such as holding self-efficacy skills training workshops increase the level of life satisfaction among nursing students as one of the important and influential strata of society. One of the most important and influential segments of society has grown.
