Introduction: The present study aimed to investigate the relationship between safety climate and safety performance with respect to the mediating effect of safety knowledge and safety motivation.
 

Material and method: The study population was a sample of 354 subjects chosen by Cochran formula among all 4252 employee in Sarcheshmeh copper complex in Rafsanjan, 2015. The participants were selected according to stratified random sampling. Data collection was done by four questionnaires (safety climate, safety knowledge, safety motivation, and safety performance).The Cronbach's alpha and composite reliability (CR) were used to evaluate the reliability of the study tools and the coefficient of all variables were acceptable with values of higher than 0.8. Moreover, validity of the questionnaires was confirmed by convergent validity and divergent validity, R-square, effect size (f2), and Q2 criterion. The Average Variance Extracted (AVE) was greater than 0.4 which is relatively acceptable. The obtained data were analyzed using SmartPLS software. 
 

Result: Kolmogorov-Smirnov test was used to investigate the normality status of variables distribution. Furthermore, Structural Equations Method (SEM) was adopted to test the research hypotheses.The results confirmed all the research hypothesis and showed safety climate direct effect on safety performance. Moreover, safety motivation and safety knowledge have mediating role in the relationship between safety climate and safety performance. Safety motivation can also mediate the relationship between safety knowledge and safety performance.
 

Conclosion: Overall, it is recommended to improve safety climate, considering its influencing components. Employees' safety knowledge and safety motivation should also be promoted. Additionally, it is recommended to determine other personal and organizational parameters and include them into the model. By determining the mediating variables, their role in the safety performance can be investigated.

Introduction: Recognizing the personality traits of employees and examining the role of these traits in motivating people’s safety can greatly lead to the formation of safe behavior of employees. Considering the significant importance of reducing adverse events and developing safe behaviors, the present study aimed to investigate the role of nurses’ personality traits in their safety behaviors with the mediating role of safety motivation during 2019-2020. 
Material and Methods: This is a descriptive-analytical study conducted among nurses working in educational hospitals affiliated by Qazvin University of Medical Sciences, from which 435 individuals were selected by multi-stage proportional sampling method. Data were collected using McCray and Costa Five-Factor Personality Questionnaire, Saleh Motivation Questionnaire (2010) and Safe Behavior Questionnaire (2016) and analyzed by SPSS software version 26 and AMOS software version 23.
Results: The path coefficients between nurses’ personality traits and their safety motivation (0.557) and safety motivation with safe behavior of individuals (0.267) were statistically significant (p<0.05). Furthermore the path coefficient between nurses’ personality traits and safe behavior (0.573) was statistically significant (p<0.05).
Conclusion: Results affirmed that safety motivation in nurses had a significant effect on their safety behavior. Therefore, it is recommended to improve safety motivation through establishing an incentive systems to appreciate the employees who had an appropriate and safe behavior in the workplace.

Introduction: Workplace safety is a critical factor for organizational success and the protection of human capital. Safe behavior among employees is influenced by various psychological and organizational factors, including safety climate and safety motivation. Considering the importance of enhancing safety motivation and the lack of standardized indigenous tools in Iran, this study aimed to culturally adapt the Self-Determination Safety Motivation Scale (SDSM) and examine its mediating role in the relationship between safety climate and employees’ safe behavior at Kavir Steel Complex in Aran and Bidgol County.
Material and Methods: This analytical cross-sectional study was conducted in 2024 among 256 production line employees. Data were collected using the Safety Climate Questionnaire, the Safe Behavior Questionnaire, and the Persian-adapted SDSM. The adaptation process included forward–backward translation, content validity evaluation by experts, and confirmatory factor analysis. Data were analyzed using SPSS version 26 and structural equation modeling with SmartPLS version 4.
Results: The findings indicated that safety climate had a positive and significant effect on safe behavior (β = 0.608, p < 0.001), and safety motivation significantly mediated this relationship (β = 0.388, p < 0.001). It is noteworthy that the direct relationship between safety climate and safety motivation was significantly negative. The structural model explained approximately 42% of the variance in safety behavior (R² = 0.419), indicating satisfactory predictive power. Model fit indices (NFI = 0.91, SRMR = 0.06) demonstrated a satisfactory model fit. Convergent validity, discriminant validity, and construct reliability were all confirmed at acceptable levels.
Conclusion: The results highlight the importance of fostering a positive safety climate and strengthening employees’ intrinsic motivation in high-risk environments to reduce workplace accidents and promote organizational health. These findings can serve as a foundation for policy-making and training programs in the field of HSE.
