Objective: Despite numerous studies on the influence of regular engagement in physical activity and sports on mental health and quality of life across various demographics, there has been limited focus on its impact within the nursing profession. As a result, this study seeks to explore the effects of sports and physical activity participation on the mental health and quality of life of nurses.Methods: The current study utilized a descriptive correlational design and was conducted in a cross-sectional manner. The target population consisted of all nurses employed in the hospitals of Tehran. The research sample was selected using an available sampling method, specifically among nurses who expressed their willingness to participate in the study. A total of 384 male and female nurses took part in the research and successfully completed the provided questionnaires. Standard questionnaires were used for data collection. Pearson correlation test and the structural equation modeling were used for data analysis.Results: Results reveled that physical activity significantly affected depression (T= - 5.254), anxiety (T= - 6.471) and stress (T= - 4.527). In addition, physical activity significantly affected quality of life (T=3.627). Results of model fit are presented in Table 3 and indicated that the research model has good fit. Conclusion: This implies that nurses could greatly enhance their well-being through increased engagement in physical activity and a decrease in sedentary habits. As a result, we strongly urge healthcare policymakers to implement measures aimed at increasing physical activity levels among nurses.

 Objective: This research demonstrates that the practice of mindfulness training led to a notable decrease in occupational stress and an improvement in the overall quality of life for professionals working in operating rooms.Methods: The method of the present research was practical in nature and quasi-experimental in the form of pretest-posttest with a control group. The statistical population of this research included all operating room experts in Tehran hospitals. 50 people from this community were selected by convenience sampling method and were randomly divided into two experimental (25 people) and control (25 people) groups. Data was collected using standard questionnaires. T tests and ANCOVA were used to analyze data. Results: The results showed that there is no significant difference in both occupational stress and quality of life in the pretest (both P>0.05). However, it was observed that experimental group had significantly lower occupational stress and higher quality of life compared to control group in the posttest (both P=0.001). Finally, the results of ANCOVA showed significant differences between experimental and control groups in both occupational stress and quality of life (both P=0.001).Conclusion: These findings indicate that mindfulness can play a crucial role in managing work-related stress among operating room experts. Consequently, by actively participating in mindfulness activities, it is plausible to create more favorable circumstances for professionals working in operating rooms in terms of their quality of life.

Objective : The purpose of the present research was to investigate the impact of innovative organizational climate on the job performance of private sector employees, taking into account the mediating role of job motivation and self-efficacy. Methods : A descriptive-correlation approach was employed in the current investigation, utilizing structural equation modeling. The population of the study consisted of 384 employees from the private sector, aged between 21 and 49 years (with a mean age of 35.11±8.17 years), who willingly participated in the present study. The research was conducted in Tehran, Iran, in the year 2023. The participants were selected through a convenience sampling method, adhering to the guidelines outlined by Krejci and Morgan. Standard questionnaires were used for data collection. Pearson correlation test and structural equation modeling were used for data analysis. Results : Results revealed that innovative organizational climate significantly affected job performance (T=6.284). Moreover, innovative organizational climate significantly affected job motivation (T=11.594). Furthermore, innovative organizational climate significantly affected self-efficacy (T=9.509). In addition, job motivation had significantly mediated the relationship between innovative organizational climate and job performance (P<0.001). Finally, self-efficacy had significantly mediated the relationship between innovative organizational climate and job performance (P<0.001). Conclusion: Based on the findings of this research, it is recommended that market holders focus on promoting and enhancing the factors and components that contribute to the innovative organizational climate of private-sector employees. Additionally, greater emphasis should be placed on job motivation and self-efficacy of the private-sector employees.
