RESUMEN
Negative job stress puts harmful effects on physical and psychological health of workers. However, the effects of stress can be mediated by other variables. This study examines the relationship between job stress, work pressure and all the rate of reported incidents. Statistical research community included all workers of Isfahan Steel Company in the winter 1388 that among them,189 individuals were selected as sample using stratified random sampling method [from the list of workers per sector] and they responded to questionnaires including 10 questions of job stress, 4 questions of work pressure and 22 questions of the rate of reported incidents. Data was analyzed using Pearson correlation coefficients and hierarchical regression. Results showed that there was a significant internal correlation among study variables [job stress, work pressure and the rate of reported incidents] [p<0.05]. In addition, regression analysis showed that job stress on the rate of incidents reported directly and indirectly through perception of job pressure was effective [p<0.05]. Similarly, in the inverse mediation analysis, job stress mediated relationship between work pressure and the rate of reported incidents [p<0.05]. reducing job stress by changing workers' perceptions of work pressure can lower the rate of reported incidents and also the reduction of work pressure perception by improving job stress can be effective in incidence of occupational accidents
