Background and Objective: Self-efficacy, one's belief in his ability to succeed in different situations, can have positive or negative effects on mental health. Students are considered as the community builders, and thus paying attention to their psychological dimensions is a paramount importance to health of community.  This study aimed at determining the relationship of self–efficacy and mental health with academic achievement of students in Bam nursing school.

Material and Methods: This descriptive study was conducted on all students with eligibility criteria in 2011.  The instruments were General Self–Efficacy Scale (GSES), Symptom Checklist-25 (SCL-25) and Grade Point Average (GPA) for academic achievement. To analyze the data, we used Ttest, ANOVA and Pearson correlation.

Results: The level of self-efficacy was weak in 3.6 %, moderate in 84.8 % and strong in 11.5% of students. Regarding mental health aspects, the highest score was related to psychotism and depression (4.21) and the lowest to Obsessive-compulsive (3.43). The mental health of students with strong self-efficacy was higher than that of others. GPA was not correlated significantly with self-efficacy (p=0.44, r=0.062) and mental health status (p=0.96, r=0.044).

Conclusion: Mental health and academic achievement are not adequate therefore, we recommend planning some educational program based on self-efficacy theory to improve both mental health and academic achievement.

Background and Objective: Today, the role of religiosity, happiness, locus of control and coping strategies has been considered in prevention and treatment of general health and spiritual well-being problems. Concerning the importance of nursing, this research aimed to investigate the relationship between religious orientation, happiness, locus of control and coping strategies and spiritual well-being among nursing students.

Material and Methods: This correlational study was conducted on 140 selected via stratified random sampling among 228 nursing students of Islamic Azad University of Pishva in 2013-14 academic year. The questionnaires were Allport & Ross religiosity (1967), Argyle & Lu happiness (1990), Rotter locus of control (1975), Lazarus & Folkaman coping strategies (1993) and Paloutzin & Ellison spiritual well-being (1982). The data was analyzed by stepwise regression using SPSS-19 software.

Results: The findings showed that the internal religiosity orientation (r=0.48), happiness (r=0.34), internal locus of control (r=0.19) and problem solving strategies (r=0.17) had a positive significant correlation with spiritual well-being and external locus of control (r=-0.21) had a negative significant relationship with spiritual well-being.  The Internal religiosity orientation, external locus of control and happiness could predict 37 percent of variance of spiritual well-being in that the share of internal religiosity orientation variable was 23 percent.

Conclusion: Given the importance of internal religiosity orientations, external locus of control and happiness in predicting spiritual well-being, we recommend that programmers, therapists and psychosocial counselors consider them in their programs to promote spiritual well-being of nursing students.
