ارزیابی رابطه استرس شغلی و اعمال ناایمن با حوادث شغلی در یک صنعت خودروسازی

Introduction & Objective: Nowadays the vehicle manufacturing industries in Iran are critical sites as far as occupational accidents are concerned. At the same time, occupational stress and unsafe acts have also been recognized as effective factors in increasing the risk of mental and physical health problems and occupational accidents. The main aim of this research was to evaluate the relationship between job stress and unsafe acts with occupational accidents. Materials & Methods: Data were collected using of “safety behaviors sampling technique”, standardized job stress questionnaire and analytical accident indices were calculated. The selection method of all samples was on a random basis. The information was then analyzed using Excel, SPSS and appropriate statistical tests. Results: The results of the study showed that there was a significant relationship between job stress and unsafe acts, the level of stress and unsafe acts with the number of occurred accidents (p-value<0.05). The study of the relationship between job stress, unsafe acts and occupational accidents via regression logistic test showed that increasing one percent in unsafe acts have more effect on accidents than increasing one grade in job stress. So, the rate or probability accidents can be predicted in organization by changes in the two mentioned variables. Conclusion: Reducing or eliminating identified effective stress factors and decreasing unsafe acts require the investment and implementation of an occupational stress management program.
