Abstract
Introduction: Nurses as the most important part of human resources in the health service system are often faced with problems associated with shift work. The present study aimed to examine a mediating role of sleep quality in the relationship between workload and physical and mental health among nurses.
Methods: This cross-sectional study was conducted on 236 nurses working in three educational hospitals in Bojnord city. To collect data, the survey of shiftworkers (SOS) questionnaire was used. Data were analyzed using the structural equation modeling by AMOS-21 and SPSS 19 software packages. In addition, the Preacher and Hayes’ SPSS Macro program was used for testing mediation.
Results: The results showed that the proposed model fitted the data properly. Also, workload directly affected only physical health, and the quality of sleep had a mediator role in the relationship between workload and physical and mental health.
Conclusions: Sleep quality as an important variable can mediate the relationship between workload and physical and mental health in nurses. So, it is suggested that interventional interventions to improve the health of the staff be focused on adjusting and shifting job shifts and teaching the principles of sleep hygiene to them.

Abstract
Background: The majority of research have led to interventions such as stress management design and have neglected the role of psychosocial factors in occupational stress. The aim of current research was to the relationship between occupational stress and health consequences among the workers in regards with the perceived organizational support.
Methods: 211 individuals of Isfahan Steel Company were selected according to the stratified random sampling method and completed questionnaires about demography characteristics, Occupational stress, incident reporting rate and perceived organizational support. The collected data were analyzed by descriptive index and multiple regression analysis using SPSS18.
Results: Results showed that there were significant relationships among perceived organizational support, Occupational stress and incident reporting rate (P<0.05). Also, hierarchy regression analysis showed that the relationship between Occupational stress and incident reporting rate was partially mediated by perceived organizational support (P<0.05).
Conclusion: The results of this study indicate that perceived organizational support can modify the relationship between occupational stress and involvement in work accidents, and as a result, employees are less involved in risk behaviors and accidents are less caused by occupational stress.
