The effects of psychological risk factors at work on cognitive failures through the accident proneness

Background Various agents such as psychosocial items and accident proneness can affect cognitive failures through different paths. The probable paths are the direct effects of workplace psychosocial items on cognitive failures and their indirect effects on cognitive failures through the mediator variable of accident proneness, which has not yet been studied by others. Thus, the present study aimed to investigate these paths. Methods This cross-sectional study was conducted on 164 male employees of Karoon Sugar Company in 2018. The participants were asked to complete a background and demographic questionnaire, Broadbent cognitive failures scale, accident proneness questionnaire, and Copenhagen psychosocial questionnaire. Obtained data were analyzed and modeled using the statistical descriptive method, ANOVA, independent t-test, Pearson correlation test, and path analysis in the SPSS and AMOS software. Results The results of the path analysis showed that, not only, some psychosocial risk items had a significant direct effect on cognitive failures, but also, they could affect cognitive failures through the accident proneness, indirectly. Work-family conflict and social support from supervisors by coefficients of 0.188 and – 0.187 had the highest direct effects, respectively. The highest indirect effects belonged to justice and respect, and work-family conflict by coefficients of - 0.220 and 0.199, respectively. The highest total effects were also related to the work-family conflict and justice and respect by coefficients of 0.387 and – 0.381, respectively. Conclusions In total, our results showed that some psychological items could, directly and indirectly, increase cognitive failure through accident proneness.

The effect of work locus of control and general health on accident - proneness : The mediator role of effort - reward imbalance

Introduction: Workerschr('39') 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. Methods: 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. Results: 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. Conclusion: 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.of work locus of control and general health on accident-proneness with the regard to the mediating role of effort-reward imbalance.

Modeling of individual and social factors leading to occupational accidents among workers of Isfahan Steel Company using smartpls3 software

Introduction: Human factor can be regarded as the most important and basic factors to cause the occurrence of occupational accidents. Workers' accident-proneness is considered an inherent and coherent feature among these factors, therefore, recognizing its determinants could be effective in preventing such accidents. The present research has been done in among workers of Isfahan Steel Company with the aim of modeling the individual and social factors that affect occupational accidents. Methods: This analytical and cross-sectional research was conducted in 2018 using structural equation modeling (SEM) with partial least square approach. The sample size of the study 450 people (225 case, and 225 control) esfahansteel company were selected. Data analysis was performed in SPSS-23 and SMARTPLS3. Results: The obtained results indicated that the measurement and structural models was fitted.In addition, results demonstrated that all assumptions of the research were significant with the exception of the theory of effect of the relationship between individual factors and accident- proneness. Conclusion: The current study showed that people working in this industry became more vulnerable to the incident due to being exposed to stress, effort-reward imbalance and work family conflict and they increased the possibility of incidents and unsafe acts in the industry. Also, by checking the general health and work locus of Control for preventing occupational accidents in the screening process, people with internal control can be selected for stressful occupations.
