Validation of a Short Measure of Effort‐Reward Imbalance in the Workplace: Evidence from China: Jian LI, et al . Mannheim Institute of Public Health, Social and Preventive Medicine, Mannheim Medical Faculty, Heidelberg University, Germany—Objectives Work stress is an emergent risk in occupational health in China, and its measurement is still a critical issue. The aim of this study was to examine the reliability and validity of a short version of the effort‐reward imbalance (ERI) questionnaire in a sample of Chinese workers. Methods A community‐based survey was conducted in 1,916 subjects aged 30−65 years with paid employment (971 men and 945 women). Results Acceptable internal consistencies of the three scales, effort, reward and overcommitment, were obtained. Confirmatory factor analysis showed a good model fit of the data with the theoretical structure (goodness‐of‐fit index=0.95). Evidence of criterion validity was demonstrated, as all three scales were independently associated with elevated odds ratios of both poor physical and mental health. Conclusions Based on the findings of our study, this short version of the ERI questionnaire is considered to be a reliable and valid tool for measuring psychosocial work environment in Chinese working populations.
