The finding of the study showed that spiritual well-being level of most of the students was high and moderate. This corresponds to those of Rahimi et al. (
18) and Hsiao et al. (
19). High level of spiritual well-being may be resulted from cultural and religious conditions of Iran’s society. In the current study, females’ mean score of spiritual well-being was more than that of males and this finding corresponds to that of the study by Saydshohadaiet al. (
20).
Also, in the study by Kandaasmay et al. in India (
21), females` spiritual well-being level was more desirable than that of males. It can be concluded that, in Islamic societies, religious beliefs in are stronger in females than in males.
Also, corresponding with the finding of the studies by Mesbah about the student of University of Tehran (
22) and Dixon et al. (
23), male students showed more significant hopelessness than female students and specifying this fact needs more studies. Further studies on the attitudes of the two genders toward future are recommended.
The result of the current study did not show a signification relationship between spiritual well-being and education and this corresponds to the results of the study by Highfield (
24) and does not correspond to those of Saydshohadai et al. (
20) and Rezai et al. (
25).
These results showed a significant relationship between spiritual well-being and education in patients with cancer and this relationship was stronger in the patients with elementary education. The difference between these results may be attributed to the statistical population of the current study including healthy students studying at university that were not very different regarding the educational level.
Another result is the significant relationship between hopelessness and spiritual well-being. In the current study, the students with higher spiritual well-being level felt less hopeless and it corresponded to the results of the studies by Ghobari et al. (
26) and Daaleman (
27).
In other words, people with more spiritual well-being felt less hopeless according to the findings of the current study and comparing the results with those of the previous studies, it can be concluded that in most cases there was a significant and negative relationship between spirituality, hopelessness, and also depression indicating the intensity and strength of this relationship. Among social factors, it can be referred to important and preventive role of spiritual well-being against disorders of mental well-being.
According to the results of the current study, there was a significant and positive relationship between spiritual well-being and self-efficacy. Yarasi (
28) found a significant and positive relationship between these two variables corresponding to the result of the current study.
The results of the current study corresponded to those of Asghasri et al. (
12) and Duggleby et al. (
29), which focused on the development of self-efficacy beliefs.
According to Bandura, when felling stress, those who see themselves efficient and capable to confront difficulties try more to overcome and cope with those difficulties, but those who see themselves inefficient and incapable give up easily and feel anxious, depressed, and hopeless (
30). The findings of the current study showed a significant and revers relationship between hopelessness and self-efficacy.
This result corresponded to the results of Najafi et al. (
31). Results of the current study showed that self-efficacy was a strong predictor for mental well-being. According to Bandura’s theory about self-efficacy, emotions, cognition, and one’s thoughts, it is not expected to obtain these results since when people face negative events, felling self-efficient helps them to control these situations and events and as a result they can control and protect themselves against their mental problems.
Among the limitations of the current study, investigating the students of only three faculties due to time limit can be mentioned. Participants’ tiredness, lower level of trust and responsibility to answer the questions were other limitations of the study.
5.1. Conclusions
According to the current study results, spiritual well-being plays an important role in predicting hopelessness and self-efficacy of students. Therefore, the authorities of educational system should consider it when they want to codify the educational system for students. In fact, promoting psychological well-being is considered as one of the basic foundations in education, which should be taught to students.
