Abstract:
Objective: An important factor in the prevention of industrial accidents is the employees’ ability to maintain their awareness of the work situation, understand the information it holds, and predict the development of the situations. In this study, we examined the role of work stress and sleepiness in predicting work situation awareness among workers.Methods: The present study was a cross-sectional study, conducted in 2014. The sample consisted of 180 employees in the National Petrochemical Company. They were selected according to the stratified random sampling method and responded to questionnaires about demographic characteristics, work situation awareness of Sneddon, Mearns, and Flin (2013), work stress of Cohen et al. (1983), and Epworth sleepiness scale. The data were analyzed by correlation coefficient and stepwise regression by using the SPSS 15.Results: The results showed that there were internal correlation among work stress, sleepiness, and work situation awareness. Also, the results of stepwise regression analysis revealed that work stress and sleepiness significantly predicted, respectively, almost 23% and 26% of variances of work situation awareness among workers.Conclusion: According to the findings of the present study, work stress and sleepiness can predict work situation awareness. Therefore, considering these variables can be important in promoting the awareness of work situation among workers.
Machine summary:
They were selected according to the stratified random sampling method and responded to questionnaires about demographic characteristics, work situation awareness of Sneddon, Mearns, and Flin (2013), work stress of Cohen et al.
Also, the results of stepwise regression analysis revealed that work stress and sleepiness significantly predicted, respectively, almost 23% and 26% of variances of work situation awareness among workers.
Conclusion: According to the findings of the present study, work stress and sleepiness can predict work situation awareness.
e. having a high awareness of job duties, workplace conditions, and how they change in the near future to predict the development of later situations (Sneddon, Mearns, & Flin, 2006).
Cognitive skills such as work situation awareness are known to be susceptible to the elements of work-related conditions such as work stress and sleepiness (Sneddon, Mearns, & Flin, 2013).
Discussion</H2> The result of the present research showed that work stress could significantly predict work situation awareness among workers.
This result is consistent with the findings of the previous studies (Sneddon, Mearns, &amp; Flin, 2006) and can be interpreted on the basis of the following possibilities: Individuals reporting higher levels of stress were found to have poorer work situation awareness (Wickens, 2002).
Fatigue due to sleep disruption in petroleum and chemical indus- tries is part of the working and these results show that this is detrimental to employees by decreasing their work situation awareness levels (Sneddon, Mearns, &amp; Flin, 2013).
The findings of this research emphasize the importance of work stress and sleepiness variables in predicting work situation awareness among workers.
