To evaluate reliability and validity of the effort-reward imbalance (ERI) in the Chinese version.
A cross-sectional survey was conducted comprising a large sample of 4782 subjects in China, using ERI in the Chinese version. This scale contained 23 scaled items while the questionnaire including questions on the effort and reward at work, over-commitment, the full CES-D scale of depression and a range of other characteristics. Reliability analysis was applied to evaluate reliability of the ERI scale in the Chinese version and factor analysis was applied to analyze validity of the scale.
Theoretical hypothesis on the ERI model was supported by the data derived in this study. Reliability and validity of the effort sub-scale, the reward sub-scale of the ERI scale in the Chinese version seemed to be better, but reliability and validity of the over-commitment sub-scale were not perfect.
The results of the study showed that the effort sub-scale, the reward sub-scale of the ERI in the Chinese version was applicable to the Chinese population but the scaled items of the over-commitment sub-scale should be further modified.
评估中文版工作付出-回报失衡（ERI）模型的信度和效度。
采用中文版ERI模型对中国4782名受试者进行大样本横断面调查。该量表包含23个计分项目，问卷包括工作付出与回报、过度投入、完整的抑郁症状自评量表（CES-D）以及一系列其他特征的问题。应用信度分析评估中文版ERI量表的信度，应用因子分析分析该量表的效度。
本研究所得数据支持ERI模型的理论假设。中文版ERI量表中付出分量表和回报分量表的信度和效度似乎较好，但过度投入分量表的信度和效度并不理想。
研究结果表明，中文版ERI的付出分量表和回报分量表适用于中国人群，但过度投入分量表的计分项目应进一步修改。
