This study aimed to develop the Chinese version of the New Brief Job Stress Questionnaire (New BJSQ) and investigate its reliability and validity. The survey was administered at two time-points separated by a two-week interval among Chinese workers. The Chinese version of the New BJSQ was developed according to the international guidelines. Cronbach’s alpha, intra-class correlation coefficients (ICCs), and Pearson correlation coefficient were calculated to assess the reliability. A variance explained by the first factor was calculated to examine factor-based validity, and confirmatory factor analysis was performed (CFA) to determine the construct validity. Baseline and follow-up analyses included 516 and 52 workers, respectively. In most scales, sufficient internal consistency and test-retest reliability were observed, and principal component analyses demonstrated that the first factor explained more than 50% proportion of the variance. CFA showed that the four-factor model (Job demands, Task-level job resources, Workgroup-level job resources, and Organizational-level job resources) demonstrated a moderate fit, similar to the original version. The Chinese version of New BJSQ showed good reliability and moderate validity. Future studies should explore content and construct validities and the factor structure of the Chinese version of the New BJSQ in more detail.
