“…25,26 The reliability values (Cronbach α) for job demand (eg, "I feel that I have too much work"; 1 = "usually," 2 = "sometimes," and 3 = "never") and job control (eg, "Can you determine the content of your work and methods used to complete tasks?

“…However, radical measures to preserve good mental health, such as the limitation of working hours, were not defined therein. In Japan, an association between lifestyle and mental stress has been noted in several studies (Ezoe & Morimoto, 1994a, 1994bIrie et al, 1997;Kawakami, Haratani, Kaneko, & Koizumi, 1987;Sugisawa et al, 1993Sugisawa et al, , 1994.

“…Associations between working conditions such as work-hours and mental health have been also reported (Kawakami & Haratani, 1999). However, few investigations have been conducted into the relationship between mental health and working conditions as well as lifestyle (Sugisawa et al, 1993(Sugisawa et al, , 1994. This prompted us to investigate this relationship with regard to more detailed factors.…”

Healthy Work and Lifestyle Scores were totalled, and their influence on the prevalence of mental symptoms was investigated. A cross-sectional design was employed in this study. Participants were workers in a telecommunications enterprise who had received annual health check-ups from 1995 to 1997 and were between 20 and 59 years of age. A self-administered questionnaire survey obtaining information about sex, age, past history of disease, present illness, working conditions, lifestyle and subjective mental symptoms was conducted once a year. Workers with a past history of disease or present illness were excluded from the analysis. In total, 66 004 questionnaires were analysed in this study. Favourable lifestyles and working conditions were enumerated; Healthy Work and Lifestyle Scores were totalled, and their influence on mental symptoms was also investigated. It was found that for every year, the result of ANCOVA suggested that the lower the Healthy Work and Lifestyle Scores, the higher the age-adjusted mean number of perceived mental symptoms. The results of multiple comparisons revealed significant deterioration in the number of perceived mental symptoms in the groups whose Healthy Work and Lifestyle Scores were 0-4-, 5-and 6-point. This comprehensive score suggested that working conditions and lifestyle correlated with the mental health of Japanese workers.

Karojisatsu in Japan: Characteristics of 22 Cases of Work-Related Suicide: Takashi AMAGASA, et al. Mental Clinic Misato-With the rapidly increasing number of work-related suicides in Japan (Karojisatsu, in Japanese), both applications for worker's compensation insurance and civil suits are proliferating. The phenomenon of work-related suicide is examined along with the process and related factors. With informed consent from bereaved families, two certified psychiatrists independently reviewed and summarized 22 insurance and legal reports filed by psychiatrists on employee suicides that were related to heavy workloads. A clinical epidemiologist participated in discussions with psychiatrists to reach a consensus concerning the cause of the suicides. Only one case involved a female. Seventeen had experienced personnel changes, such as a promotion or transfer. Low social support was recognized in 18, high psychological demand in 18, low decision latitude in 17, and long working hours in 19 cases (more than 11 hours per day for 3 months or more, and without a day off in 9). The subjects had depressive episodes by the ICD-10 criteria and showed suicidal signs. Ten of them saw a general practitioner because of unspecified somatic complaints, but no effective measures were taken. None of them had a history of psychiatric consultation or had received mental health education dealing with job stress management. Although causality cannot be made from this case series report, we hypothesize that long working hours, heavy workloads, and low social support may cause depression, which can lead to suicide. Appropriate countermeasures are urgently needed and the present findings suggest some of them are possible. (J Occup Health 2005; 47: 157-164)
