Bullying in the workplace is an increasingly recognized threat to employee health. We sought to test three hypotheses related to the determinants of workplace bullying: power distance at work; safety climate; and frustration related to perceived social inequality. A questionnaire survey was administered to a nationally representative community-based sample of 5,000 residents in Japan aged 20-60 years. The questionnaire included questions about employment, occupation, company size, education, hou

The present study showed acceptable levels of reliability and validity of the Japanese version of the NAQ-R among Japanese civil servants.

The results of this study suggested that the J-MWIS has moderate internal consistency reliability and good construct validity.

The results of the current study suggest that the presence of bullying in the workplace can have a detrimental effect on employees' mental health even if they are not personally victimized.

This study investigated the prospective association between supervisor leadership styles and workplace bullying. Altogether 404 civil servants from a local government in Japan completed baseline and follow-up surveys. The leadership variables and exposure to bullying were measured by Multifactor Leadership Questionnaire and Negative Acts Questionnaire-Revised, respectively. The prevalence of workplace bullying was 14.8% at baseline and 15.1% at follow-up. Among respondents who did not experience

The possible associations of intragroup and intergroup conflict at work with psychological distress and work engagement were investigated in a cross-sectional study in a manufacturing factory in Japan. A self-administered questionnaire was sent to all employees, and 255 responses were returned (a response rate of 84%). Data from 247 workers (187 males and 60 females) with no missing values were analyzed. Intragroup and intergroup conflict at work, psychological distress, and work engagement were

Low personal resilience predicted post-traumatic stress symptoms among local government employees who experienced some house damage or injury during the Great East Japan Earthquake. This result may indicate that resilience reduces the onset of post-traumatic stress symptoms, even when faced by the difficulties imposed by a natural disaster such as an earthquake.

The effects or moderating factors were limited on the longitudinal association between bullying and mental health because psychological distress at baseline was the strongest predictor of subsequent psychological distress.

The results of this study showed different high-risk groups for bullying or mental health during the pandemic. Any intervention to decrease workplace bullying or mental health problems should focus not only on previously reported vulnerable workers but also workers who have experienced a change in work style or job demands.
