To measure workplace victimization in Japan, the Japanese workplace victimization scale (JWV) was developed and determinants of workplace victimization were examined. Japanese employees (N=500; mean age 38.2 years; 317 males, 183 females), working for corporations in Japan participated voluntarily by responding to a questionnaire tailored for this study. The results of exploratory factor analysis indicated that JWV consisted of three dimensions: (a) “intentional insult” (seven items such as, “negative comments about me were made to others.”), (b) “mean treatment” (six items such as, “I was threatened with physical harm.”), (c) “impolite behavior” (four items such as, “I was put down in front of others.”). Confirmatory factor analysis verified that the three-factor structure had acceptable fit. Path analysis by SEM (structural equation modeling) indicated that job stressors affected workplace victimization, and that workplace victimization influenced workplace withdrawal, and psychological variables, leading to psychosomatic diseases. Future research issues, as well as limitations of the study are discussed.
