Objective The concept of self-endangering work behavior (SEWB) was recently proposed to describe problematic behaviors to cope with heavy workloads and self-management. Although SEWB may enable workers to achieve immediate goals, it risks health and long-term work capacity. In this study, we developed a Japanese version of the SEWB (J-SEWB) scale, which was originally in German, and verified its validity and reliability.Materials The original SEWB scale consisted of 21 items, constituting five subscales: “Intensification of working hours,” “Prolongation/extension of working hours,” “Refraining from recovery/leisure activities,” “Working despite illness,” and “Use of stimulating substances.” We translated the scale into Japanese, then checked the wording using back-translation.Methods The J-SEWB scale and questions for working conditions and sociodemographic variables was administered via an online survey with 600 participants registered with an internet survey company in Japan. Cronbach’s α coefficients were calculated for each subscale to assess internal consistency. Construct validity was examined using principal factor analysis with equamax rotation. An analysis of variance evaluated the relationships of J-SEWB scores with working conditions and sociodemographic variables.Results Cronbach’s α coefficients ranged from 0.846 to 0.964 for five subscales, and 0.957 for all 21 items (total J-SEWB score) in 600 participants. The factor analysis identified five factors, classifying 21 items into corresponding subscales. Total J-SEWB scores were significantly higher for flexible work as well as longer working hours.Conclusions The J-SEWB scale appears to be an effective tool for assessing SEWB in Japanese employees, with satisfactory reliability and construct validity.

The study aim was to examine whether flexible working time was associated with burnout and poor perceived health in relation to the work-related psychological/behavioral factors of self-endangering work behavior (SEWB), workaholism, work engagement, and job stressors. We analyzed data obtained from an Internet survey of 600 full-time Japanese employees. We also proposed a causal model using path analysis to investigate the overall relationships of burnout and perceived health to psychological/behavioral factors. The results indicated that flexible working time was associated with adverse work-related consequences and factors such as increased burnout, working hours, SEWB, workaholism, and job demands, and with positive factors such as improvement of work engagement. The path analysis suggested that burnout was caused by workaholism both directly and via SEWB, and by low job decision latitude, and was reduced by work engagement. Similarly, it was observed that poor health was caused by workaholism via SEWB, and reduced by work engagement. Thus, SEWB is driven by workaholism and plays a key role in the adverse health consequences of flexible working time. For workers to benefit from flexible working time, it is important to improve workaholism, SEWB, and low job decision latitude, and to develop work engagement in the workplace.

The purpose of this study was to examine the association between psychosocial job stress (by the Job Control-Demand (JCD) model and Effort-Reward imbalance (ERI) model) and musculoskeletal (MS) symptoms among workers in China. Overall, 3,632 male and 1,706 female workers from 13 factories/companies participated in this study. Perceived job stress was evaluated by the Chinese version of the Job Content Questionnaire (JCQ) and ERI Questionnaire. Neck, shoulder and wrist symptoms were assessed by self-report during the past year. Workers reporting high job demands and low job control or high effort and low rewards had moderately increased risk for all MS symptoms. Odds ratios (ORs) were higher in workers reporting both high effort and low rewards. The combination of high physical job demands with low job control showed significant associations with MS symptoms. The effects of psychological demands on symptoms in women, effort and effort-reward imbalance on symptoms among both genders were increased as the number of regions with symptoms increased. These results suggest that high job strain and ERI are associated with neck, shoulder and wrist symptoms in Chinese factory workers independent of individual factors, physical factors, and other psychological variables.

Late in the 1970s, serious social concern over health problems due to long working hours has arisen in Japan. This report briefly summarizes the Japanese circumstances about long working hours and what the Government has achieved so far. The national statistics show that more than 6 million people worked for 60 h or more per week during years 2000 and 2004. Approximately three hundred cases of brain and heart diseases were recognized as labour accidents resulting from overwork (Karoshi) by the Ministry of Health, Labour and Welfare (MHLW) between 2002 and 2005. Consequently, the MHLW has been working to establish a more appropriate compensation system for Karoshi, as well as preventive measures for overwork related health problems. In 2001, the MHLW set the standards for clearly recognizing Karoshi in association with the amount of overtime working hours. These standards were based on the results of a literature review and medical examinations indicating a relationship between overwork and brain and heart diseases. In 2002, the MHLW launched the program for the prevention of health impairment due to overwork, and in 2005 the health guidance through an interview by a doctor for overworked workers has been enacted as law. Long working hours are controversial issues because of conflicts between health, safety, work-life balance, and productivity. It is obvious that we need to continue research regarding the impact on worker health and the management of long working hours.
