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.
A community-based survey was conducted in 1,916 subjects aged 30-65 years with paid employment (971 men and 945 women).
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.
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.
工作压力是中国职业健康领域的一个新出现的风险，其测量仍然是一个关键问题。本研究旨在检验努力-回报失衡（ERI）问卷短版在中国工人样本中的信度和效度。
对 1916 名 30-65 岁有薪就业的（男 971 名，女 945 名）社区居民进行了一项基于社区的调查。
获得了三个量表（努力、回报和过度投入）可接受的内部一致性。验证性因子分析显示，数据与理论结构具有良好的拟合度（拟合优度指数=0.95）。有标准有效性的证据，因为所有三个量表都与较差的身体和心理健康的比值比升高独立相关。
根据我们研究的结果，这个 ERI 问卷的短版被认为是测量中国工作人群心理社会工作环境的可靠和有效的工具。
