بررسی پارامترهای مؤثر بر عدم توازن تلاش-پاداش و استرس شغلی ناشی از آن: نتایج پیمایش عوامل روان-اجتماعی در محیط‌های کاری کشور ایران (IPWS)

Background and Objective: Effort-Reward Imbalance (ERI) model is one of the methods for studying occupational stress in the workplaces. Considering there has been no comprehensive study on the determining of effective individual and organizational parameters in Iran, the aim of this survey was to detect the parameters affecting perception of ERI in workers in the workplaces in Iran. Material and Methods: This cross-sectional study was executed by using the results of Iran Psychosocial Workplace Survey (IPWS) on 1116 employees of different levels of work in 2015-16. Data gathered using the ERI Questionnaire and a comprehensive list of individual and organizational parameters. To identify factors associated with ERI, multivariable logistic regression model was used. Results were reported as odds ratio (OR)with 95% of confidence interval. Results: ERI is reported in almost 50% of workers. After eliminating confounders, the logistic regression model indicated that parameters like education level (OR= 1.507, P= 0.033), having exercise (OR= 0.375, P= 0.034) and having right for choosing work-rest schedule (OR= 1.878, P= 0.002) as promoters and parameters like having second job (OR=2.069, P=0.008), perception of co-worker shortage (OR= 2.415, P <0.001) and having shift work system for work (OR= 1.822, P <0.001) act as disruptive parameters for ERI situation in the workplaces. Conclusion: According to the results of this study it can be mentioned that if intervention is requisite for improving Effort-Reward situation, parameters like education level, having exercise and having right for choosing work-rest schedule, having second job, perception of co-worker shortage and having shift work system for work should be adjusted.
