Validation and localization of farsi version of effort-reward imbalance questionnaire to measure job stress among employees of Isfahan polyacryle corporation

To be able to measure the extent of job stress, it is essential to use a standardized
tool based on a standard theoretical model. The study aims to test the psychometric properties and criterion
validity of the Farsi version of the Effort Reward Imbalance (F-ERI) questionnaire.
Methods: The Farsi version of the ERI Questionnaire was distributed to 227 male employees in Isfahan
Polyacryle Company. Internal consistency, reliability, discriminative validity, and factorial structure were
evaluated.
The relationship between scales and depression was measured assessed by using logistic regression to criterion
validity. Data were analysed by SPSS 18 and LIZREL 8.5.
Results: Mean score of effort, reward, and overcommitment were 10.7, 41.4, and 14.2 respectively; Cronbach’s
alpha coefficients were 0.61, 0.85 and 0.67 and split-half coefficients were 0.53, 0.85, and 0.65. All of itemtotal
correlations were more than 0.20; correlation between each item and its scale were more than 0.4 except
for one item. Effort and overcommitement had a good fit for construct validity.
Conclusion: Current study results indicated the Farsiversion of the Effort Reward Imbalance (F-ERI) questionnaire
is a reliable and valid tool to measure psychosocial stress at work among Farsi-speaking employees. It is
advisable to evaluate the tool in longitudinal studies and other industries which included female employees. We
