Many workers and health professionals consider that mental health at the workplace is very important in order to maintain workers' health. To improve their mental health, evaluating stress at the workplace and planning adequate stress management are necessary. This report deals with these two areas. 1. A survey on occupational stress in local government employees. In order to evaluate occupational stress, we made a set of questionnaires including the NIOSH Generic Job Stress Questionnaire (the Japanese version) and the 12- item General Health Questionnaire (GHQ), and requested employees of two local governments in Fukuoka Prefecture to answer the questions. We received replies from 300 employees, 204 males and 95 females (1 unknown), whose average age was 42.2 years old. The multiple regression analysis was used to clarify how well the GHQ score would be explained by the scale scores of the NIOSH Questionnaire. The result indicated that respondents who had higher scores of 'International Conflict within Groups' and 'Variance in Workload,' and lower scores of 'Self-Esteem' and 'Job Satisfaction' had higher scores of the GHQ. The regression explained twenty-eight percent of the GHQ score variance. The scales of 'Self-Esteem' and 'Variance in Workload' had a larger explanatory power on the GHQ score than the others. The cluster analysis of respondents also revealed that stressors might have strong influence on mental health in a group of respondents and personality factors might play a significant role in another group. 2. Training of active listening in a company. We provided one-day training of active listening (AL) for 44 employees of managerial positions in a certain company. The training included lectures and practices of AL. According to their answers to the questionnaire filled in just after the training, almost all participants were interested in mental health, and 94% of them recognized that they were under stress. All of them thought that the training was useful, and 77% replied that AL would be helpful. The questionnaire survey conducted 6 months later revealed that many of them were trying to make good use of AL.
