摘要：Organizational justice has recently attracted attention as a predictor of employee mental and physical health. However, the lack of a Japanese translation of the original English-language organizational justice scale (OJS) has precluded its application in Japan. The present study aimed to develop Japanese version of the measure of organizational justice. We translated the original questionnaire, which is comprised of 20 items, from English to Japanese. The OJS is made up of four distinct dimensions: procedural, distributive, interpersonal and information justice. A total of 229 employees responded to the Japanese version of the OJS (OJS-J), the effort-reward imbalance (ERI) model and the Kessler Psychological Distress Scale (K10). To assess construct validity, we recorded job satisfaction using the visual analog scale (VAS). Our exploratory factor analysis supported the four-factor structure model of OJS-J. Correlation coefficients between the OJS-J and ERI, K10 and VAS were statistically significant, indicating a reasonable degree of construct validity. Obtained internal consistency was markedly high (Cronbach's alpha was 0.96), and test-retest reliability as analyzed with an intraclass correlation coefficient was 0.91. These results suggest that the OJS-J is a reliable and valid measure that may be suitable for use as a predictor of employee health in the Japanese work place.
