Workplace bullying is increasingly being recognized as a serious problem within the work environment. Previous studies in European countries have reported the prevalence of workplace bullying and its association with poor mental health, using the Negative Acts Questionnaire-Revised (NAQ-R: Einarsen & Hoel, 2001), but there have been very few studies in Japan. The authors translated the 22-item NAQ-R into the Japanese language and examined the internal consistency reliability and concurrent and construct validity, including factor-based validity, of this scale in a sample of Japanese civil servants. ⋯ The present study showed acceptable levels of reliability and validity of the Japanese version of the NAQ-R among Japanese civil servants.

To investigate the occupational and genetic risk factors inducing lumbar disc degeneration in a Chinese population, and to explore their synergistic interactions. ⋯ The results of this study suggest that gene-occupation interaction might play a certain role in exaggerating lumbar disc degeneration. There is a possibility that subjects who carry mutation alleles 5A of MMP-3 and/or A of VDR-Apa are more vulnerable to lumbar disc degeneration when they are exposed to whole-body vibration and/or bending/twisting under ergonomic loads.
