Background: Given the increasing number of elderly people in the world and in Iran, and the need to pay attention to their health (physical and mental), it is important to be aware of the status of health indices and factors among these people. The main issue was to investigate the status of mental health indices in Iranian elderly people in order to provide a scientific and practical approach to improve quality of life. Aims: The aim of this research was to assess the status of mental health indices in Iranian elderly people. Method: This study was descriptive and was conducted using field study. 150 elderly people were selected in the city of Shiraz by multi-stage cluster sampling and were assessed by the elderly mental health indices questionnaire. The data were analyzed by one way analysis of variance. Results:  The results showed that for the elderly people, family, religious, psychological, physical, social and economic dimensions were the most important dimensions with mean score (out of 5) of 4.27, 4.05, 3.84, 3.56, 38. 3 and 24.2, respectively. Also, the most important indices of mental health were "having a proper parenting pattern", "mutual understanding with the spouse", "loving relationship with the spouse", "training the children effectively", and "believing in God". Comparison of the status of indices showed that the elderly men had better status in family (t = 2.25, p= 0.002), social (t= 3.18, p= 0.002), and psychological dimensions (t=2.28, p = 0.002) than the elderly women. Women also had better status in religious (t= -2.35, p= 0.002), economic (t= 2.14, p = 0.002) and physical (t=-2.45- p= 0.002) dimensions. Conclusions:  The results showed that parental relationships, effective marital relationship, successful parenting and religious affairs are the most important factors affecting the quality of life of the elderly people. 

Background: Studies have shown that lifestyle change through regulation and orientation to human life is effective on improving individual-educational determinants but a study which addresses the impact of this training on students' self-efficacy, outcome expectations and source of control has been neglected.
Aims: The aim of this study was to determine the effectiveness of lifestyle change training on improving self-efficacy, outcome expectations and reducing locus of external control in students.
Methods: This study was an experimental study with pre-test, post-test with control group. The research population included all students of Islamic Azad University, Tehran Research Sciences Branch in the first semester of the academic year 2020-2021. The study sample included 40 students who were selected by two-stage cluster sampling method and, then, were assigned into experiment and control groups (20 individuals per group) through random assignment method. The research tool were the scales of General Self-Efficacy (Schwarzer and Jerusalem, 1995), Student Outcome Expectations (Landy, 2003) and Source of Control (Rotter, 1966). For the experiment group, lifestyle change training (Van Pay, 2018) was held in eight 90-minute sessions, but the control group did not receive any intervention. Analysis of covariance was used to analyze the data.
Results: The results showed that lifestyle change training was effective in increasing students' self-efficacy, outcome expectations and reducing locus of external control (p<0.01).
Conclusion: Lifestyle change training can be used by therapists as an efficient way to improve students' self-efficacy and outcome expectations and reduce their external control beliefs, and thus help their academic-career success.
