Workers' accident-proneness is considered as an inherent and coherent feature in incidence of occupational accidents. Therefore, recognizing its determinants could be effective in preventing such accidents. This study aimed to investigate the effect of work locus of control and general health on accident-proneness with the regard to the mediating role of effort-reward imbalance.

This analytical and cross-sectional research was conducted in 2018 using structural equation modeling (SEM) with partial least square approach. In total, 225 employees with a history of occupational accidents in  Esfahan Steel Company were selected. Data analysis was performed using SPSS-23 and SMARTPLS3.

The obtained results indicated that the measurement and structural models were fitted. In addition, results demonstrated that all assumptions of the research were significant with the exception of the general health effect on accident proneness. 

The results of this study showed that by controlling the work environment stressors, such as balancing effort-reward, could reduce the  accident- proneness. In addition, by checking the general health and work locus of control  to prevent the occupational accidents in the sieving process, people with internal control should be selected for stressful occupations.

Human factor can be regarded as the most important and basic factors to cause the occurrence of occupational accidents. The accident proneness of the staff is recognized as an intrinsic and integrated trait of occupational accidents. Therefore, identifying factors affecting this issue can effectively prevent the occurrence of occupational accidents. This study aimed to evaluate the effect of work-family conflict, work control center, and stress on accident proneness. This analytical and cross-sectional research was conducted in 2018 using structural equation modeling (SEM) with partial least square approach. In total, 225 employees with a history of accidents were selected using sample size determining method in SEM. Data were collected using four questionnaires of work-family conflict, work control center, occupational stress, and accident proneness. Data analysis was performed in SPSS version 23 and SMARTPLS3. In this study, composite reliability (CR) was applied to determine the reliability of the research tools, which yielded an acceptable correlation above 0.7 for all variables. In addition, average variance extracted (AVE) was exploited to assess the validity of the questionnaire, which was above 0.5 and acceptable. Furthermore, divergent validity was evaluated and confirmed by the new criterion (HTMT). To evaluate the fit of the structural model, linearity criteria, significance of coefficients, R2, f2, and Q2 were applied, results of which were indicative of the proper fit of the model. In addition, results demonstrated that all assumptions of the research were significant with the exception of the theory of effect of work-family conflict on accident proneness. Recognizing the individuals prone to accidents, as well as the causes of occupational accidents are significantly important in control of industry incidents with sensitive occupations. According to the results of the study, individuals with internal control can be selected for high-stress occupations during the screening in the beginning of recruitment of employees. In addition, the organization’s management can reduce the occupational stress of the staff by decreasing work-family conflict, which leads to the improvement of performance and safety of work of these individuals.

The purpose of this study is to investigate the impact of job stress and work locus of control on job satisfaction of Tehran emergency first responders.
In this study correlational research method was used and 160 members of Tehran emergency first responders were selected through multi-stage cluster sampling method. To collect data three questionnaires including self-reported job stress questionnaire (Martinssuen, 2001), spector work locus of control questionnaire (1988) and spector job satisfaction questionnaire (1988) were used. Statistical analysis of data was performed with Pearson correlation and regression analysis.
The results of this study show there is negative significant relationship between job stress and job satisfaction. In addition, findings showed that there are significant positive and negative correlation relationships between internal and external locus of control and job satisfaction respectively. Furthermore, stepwise regression analysis showed the subscales of external locus of control, role, internal locus of control, communication and supervisors could estimate 54% of the variance in job satisfaction.
According to this study, job satisfaction can be estimated on the basis of two effective factors of job stress and work locus of control.

Emergency workers because of encounter with traumatic events are exposed to high stress. The aim of study was, the predicting mental health based on the combined role of work locus of control and job stress. In this study 160 members of Tehran Emergency workers were selected through cluster sampling method and fills the questionnaires of job stress questionnaire, work locus of control questionnaire and general health questionnaire. Statistical analysis of data was performed with Pearson correlation and regression analysis. The results showed there is negative significant relationship between job stress and mental health. In addition, there are significant positive and negative correlation relationships between internal and external locus of control and mental health respectively. Furthermore, stepwise multivariate regression analysis showed that the subscales of demands, colleagues, external locus of control, and supervisors have predicted mental health. According to the findings of the present study, mental health can be estimated on the basis of two effective factors of job stress and work locus of control.

The purpose of this study is to assess the impact of job stress and work locus of control on Tehran emergency first responders’ mental health. The sample in question included 160 members of Tehran emergency first responders who were selected through a multi-stage cluster sampling method. To collect data, three questionnaires were used including the following: the self-reported job stress questionnaire (Martinssuen, 2001), the Spector work locus of control questionnaire (1988), and the Goldberg general health questionnaire (1972). The results showed that there is a significant negative relationship between job stress and mental health. In addition, there are significant positive and negative correlation relationships between internal and external locus of control and mental health, respectively.Furthermore, stepwise multivariate regression analysis showed that the subscales of demands, colleagues, external locus of control, and supervisors could comprise an estimated 48% of variance in mental health.
Discussion and According to the findings of the present study, mental health can be estimated on the basis of the two effective factors of job stress and work locus of control.
