Background and Aim: The present study seeks to explain the effect of organizational change on employees' mental health with respect to the moderating role of job support and control.
Method: This method is descriptive and correlational. The statistical population of the study was the staff of Farshchian Sina Hospital in Hamadan, a total number of 200 people. Sample size was determined based on Morgan table to be 132 people which were randomly selected. Standard questionnaires of organizational change, general health, job support and job control were used to measure the variables.

Results: Findings indicate that 43% of employees' mental health changes are explained by organizational change. Organizational change, considering the moderating effect of job support, has a positive effect on employees' mental health. The standardized coefficient between the two variables shows that 24% of mental health changes are explained by organizational change, taking into account the adjustment effect of job support. Organizational change, considering the moderating effect of job control, also has a positive effect on the mental health of employees. The standardized coefficient between the two variables also shows that 29% of mental health changes are explained by organizational change by considering the moderating effect of job control. Therefore, organizational change has a positive effect on the mental health of Farshchian Hospital staff in Hamadan.

Abstract
Objectives: Effectiveness assessment of multifaceted long-term ergonomics interventions in an automotive company Introduction: Prevention of musculoskeletal disorders requires evaluation and improvement of work situations using ergonomic posture assessment methods. The purpose of this study was to determine the effectiveness of multifaceted and long-term ergonomic interventions in a developing automobile manufacturing company using the Rapid Office Strain Assessment (ROSA) method.
Methods: A long-term multifaceted intervention study was conducted on 70 office employees of an automotive engineering service company in three stages from 2016 to 2022. Interventions were carried out according to the scores obtained in the sub-areas of the ROSA method including chair, mouse and keyboard, telephone, and monitor. The interventions included technical-engineering and educational interventions. Finally, descriptive statistics and paired t-tests, Pearson correlation coefficient and multiple linear regression were used to analyze the data.
Results: The average score of ROSA in 2016 was 5.9 with a standard deviation of 0.66, while the average score of ROSA in 2022 was 3.85 with a standard deviation of 1.19. There was a statistically significant difference between the final score of ROSA in 2016 and 2022 (P < 0.001). Statistical tests showed that only the technical-engineering intervention had a significant effect on the ROSA final score.
Conclusion: The results of the present study have shown a favorable reduction in the final risk level of the physical condition of the employees during work due to the improvement of the physical condition as a result of the technical-engineering intervention along with the educational intervention in accordance with the components of the ROSA method.
