Background: The best way to reduce occupational injury and accident rates seems to be to investigate the social and organizational factors influencing workplace safety. Objectives: The present study examines relationships of safety motivation and work pressure with occupational accident rate among workers of Khorasan petrochemical company. Patients and Methods: In this cross-sectional study, the population consisted of all line employees working in Khorasan petrochemical company (n = 1160). Stratified sampling was used to select 300 employees. They completed measures of safety motivation, perceived work pressure, and incident reporting rate. Regression analysis was performed by SPSS software in main stage and confirmatory factor analysis was performed by AMOS software in validation stage. Results: Both safety motivation and work pressure were significantly correlated with occupational accident rate (P < 0.0001). Stepwise multiple regression analyses showed that both safety motivation and work pressure were significant predictors (R 2 = 0.302, P < 0.0001). Conclusions: Safety motivation and work pressure are important predictors of occupational accident rate. Therefore, increasing safety motivation and reducing work pressure in high-risk jobs are effective ways in which organizations can decrease occupational accident rates.

BACKGROUND: Lifestyle is one factor that forms the nurses’ health, particularly those who work in shiftwork schedules. AIMS: The aim of this study was to design and test a model for health promotion of Iranian nurses. In this model, nurses’ lifestyle was considered as the precedent, physical and mental health as the outcomes, and sleep disturbance and chronic fatigue as the mediators. METHODS: A cross-sectional study using structural equation modeling was conducted among 240 shiftworker nurses in Iran. The data collection was performed using the Persian versions of the Survey of Shiftworkers Questionnaire and Life Style Questionnaire. Bootstrap in Preacher and Hayes’ Macro program was used for testing mediation. RESULTS: Lifestyle had a weak significant direct effect on physical (β = 0.13, p < .04) and mental health (β = 0.12, p < .02), and it had a significant indirect effect on physical health via chronic fatigue (β = −0.11, p < .001) and sleep disturbance (β = −0.05, p < .01). This variable only had a significant indirect effect on mental health via chronic fatigue (β = −0.19, p < .001). The final model proposed a new significant path between sleep disturbances and chronic fatigue (β = 0.22, p < .001). CONCLUSIONS: Therefore, the hospital officials can enhance the nurses’ physical and mental well-being by providing interventions and training courses on aspects of healthy lifestyles, such as physical activity, avoidance of smoking, and maintenance of body weight.

There is limited information on the specific psychosocial risks at work that can impact sexual function. The general aim of this study was to investigate the effects of multiple dimensions of psychosocial work stressors on the male sexual function. This was a cross-sectional study conducted among 153 male nurses working in two hospitals in Iran. Sexual function and psychosocial job stressors were measured using the Persian version of the International Index of Erectile Function (P-IIEF) and the Persian version of the Health and Safety Executive (P-HSE) Management Standards Indicator Tool. The Persian version of the Work Ability Index (P-WAI) was used to assess the mediating effect of work ability on the relationship between overall stress and subscales of sexual function. The data were analyzed using Pearson product–moment correlation, one-way analysis of variance (ANOVA), and multiple linear regressions. The subscales of psychosocial job stressors, especially the subscale of role, had a significant correlation with several domains of sexual function. The regression modeling indicated that the subscales of role and job demands were significant predictors of various domains of sexual function. The effect of overall stress on intercourse satisfaction was fully mediated by WAI. In the other indicators of sexual function, overall stress score had only a significant direct effect, not mediated by WAI. Intervention programs to improve sexual function should focus on increasing nurses’ involvement in making decisions related to jobs and on using ergonomic principles related to balancing job demands and the level of nurses’ capabilities.

Background: Approximately, 90% of workplace accidents are due to human errors. The study of the relationship between individual differences and accidents and injuries are beneficial in the prevention of these accidents. The aim of the present study was to examine the relationship between extraversion, agreeableness, conscientiousness, and neuroticism and occupational accident rates in the petrochemical industry. Materials and Methods: This was a descriptive correlational study. The study population consisted of line employees of Khorasan Petrochemical Company in Bojnourd, Iran (n = 1160); 300 employees were selected using stratified random sampling. Data collection tools consisted of the NEO Five-Factor Inventory and Incident Reporting Rate Scale. In order to analyze the data, regression analysis and to validate the results, confirmatory factor analysis were performed using AMOS 21 software. Results: Findings indicate that correlation coefficients between the five-factor personality traits and occupational accident rates were significant (P < 0.001). In stepwise multiple regression analyses, of the 5 independent variables, only the 2 variables of conscientiousness and agreeableness found permit entry into the regression equation (R 2 = 0.186, P < 0.001). Conclusions: The results of this study showed the importance of conscientiousness and agreeableness as predictors of occupational accident rates. Therefore, in order to select people for working in high risk environments, such as the petrochemical industry, we should rely on these variables.
