© 2017 The Author(s). Background: Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being. However, most studies on the relationship between job crafting and employees' well-being have been conducted in western countries; thus, it is unclear whether job crafting can be effectively applied to Asian cultures, such as Japan, which emphasizes group harmony. The aim of this study was to examine the cross-sectional associations of self-reported job crafting with work engagement and psychological distress among employees in Japan. Method: A questionnaire survey through the internet was conducted among all employees of a manufacturing company in Japan. We analyzed the data from 894 respondents, all employees with regular employment. Job crafting, work engagement, and psychological distress were assessed using the Japanese version of the Job Crafting Questionnaire, the Japanese version of the Utrecht Work Engagement Scale (UWES), and the Brief Job Stress Questionnaire (BJSQ), respectively. Result: Hierarchical multiple regression showed that increasing structural job resources, social job resources, and challenging job demands was significantly and positively associated with work engagement (β = 0.31, p < 0.001; β = 0.14, p < 0.001; β = 0.36, p < 0.001, respectively). For psychological distress, increasing structural job resources was significantly and negatively associated with psychological distress (β = -0.15, p < 0.001). Conclusion: Our study suggests that increasing structural job resources is associated with higher work engagement and lower psychological distress. In addition, increasing social job resources and challenging job demands are also associated with higher work engagement.

Objectives This study of Japanese dual-earner couples examined the impact of family and job demands on one's own and one's partner's fatigue as well as gender differences in these effects. Methods A total of 2,502 parents (1,251 couples) were surveyed using a self-administered questionnaire. A crossover model was tested using structural equation modeling. Results The results of structural equation modeling analyses showed that both job and family demands independently exacerbated fatigue. There was an indirect effect of job and family demands on partner fatigue through one's own fatigue only from husbands to wives. An indirect effect of job demands on partner fatigue through partner's family demands was identified only from wives to husbands. Furthermore, there were gender differences in the crossover of fatigue. Conclusions This study shows that job and family demands influence family circumstances. When considering means to reduce employees' fatigue, gender differences in the mechanism of fatigue need to be taken into account.

Objective: The purpose of this randomized, controlled trial was to examine the effects of a psychoeducational information website on improving work engagement among individual workers with low work engagement, where work engagement was measured as a secondary outcome. Methods: Participants were recruited from registered members of a web survey site in Japan. Participants who fulfilled the eligibility criteria were randomly allocated to intervention or control groups. Immediately after the baseline survey, the intervention group was invited to study a psychoeducational website called the "UTSMed," which provided general mental health literacy and cognitive behavioral skills. Work engagement was assessed by using the Utrecht Work Engagement Scale at baseline, 1-, and 4-month follow-ups for both intervention and control groups. An exploratory analysis was conducted for a subgroup with low (lower than the median scores) work engagement scores at baseline. Results: A total of 1,236 workers completed the baseline survey. In the low work engagement subgroup, a total of 313 and 300 participants were allocated to an intervention and control group, respectively. In the high work engagement subgroup, 305 and 318 participants were allocated to an intervention and control group, respectively. The program showed a significant effect on work engagement (t = 1.98, P = 0.048) at the 4-month follow-up in the low work engagement subgroup, with a small effect size (d = 0.17). Conclusion: A web-based psychoeducation resource of mental health literacy and cognitive behavioral skills may be effective for improving work engagement among individual workers with low work engagement.

Objectives: Although incivility is a common interpersonal mistreatment and associated with poor mental health, there are few studies about it in Asian countries. The aim of this study was to develop the Japanese version of the modified Work Incivility Scale ( JMWIS), investigate its reliability and validity, and reveal the prevalence of incivility among Japanese employees in comparison with data on Canadian employees. Methods: A total of 2,191 Japanese and 1,071 Canadian employees were surveyed, using either the J-MWIS or MWIS. Japanese employees additionally answered questions on civility, worksite social support, workplace bullying, psychological distress, intention to leave, and work engagement to investigate construct validity. Results: At least one form of workplace incivility was experienced by both Japanese ( 52.3% ) and Canadian (86.0%) employees in the previous month. Internal consistency reliability of the J-MWIS was acceptable (a= 0.71-0.81), and correlation analyses also confirmed its construct validity as expected. Workplace incivility was associated with lower workgroup civility, lower supervisor and coworker support, higher workplace bullying, higher psychological distress, higher intention to leave, and lower work engagement. Confirmatory factor analyses showed that the original three-factor model (supervisor incivility, coworker incivility, and instigated incivility) fitted moderately in both Japan and Canada data, though the privacy/overfamiliarity factor was additionally extracted from exploratory factor analysis for the J-MWIS. Conclusions: The results of this study suggested that the JMWIS has moderate internal consistency reliability and good construct validity.

本研究では、未就学児を持つ日本人の共働き夫婦496組を対象に、ワーカホリズムとパートナーの精神的健康との関連における心理社会的メカニズムを検討した。ワーカホリズムがパートナーの精神的健康に影響を及ぼす心理社会的プロセスとしては、これまでに、パートナーのワーク・ライフ・バランスの悪化(家庭役割から仕事役割への葛藤の上昇)、パートナーへの社会的支援の低下、の2つのプロセスが明らかにされてきたが、本研究では、第3のプロセスとして、パートナーとのコミュニケーションに注目した。具体的には、自己のワーカホリズムが自己の心理的ストレス反応の上昇と職務満足感の低下を導き、パートナーとのネガティブなコミュニケーションを増加させることで、パートナーの心理的ストレス反応の上昇と家庭生活満足感の低下につながることを想定した。東京都某区の保育園に通わせる共働き夫婦を対象に自記式質問紙による調査を行った。想定した因果関係を共分散構造分析により分析し、モデル全体の妥当性を確認後、概念間の因果係数によりモデル各部の検証を行った。その結果、仮説モデルは男女ともに支持された。すなわち自己のワーカホリズムは、自己の心理的ストレス反応の上昇および職務満足感の低下を媒介して、パートナーへのネガティブなコミュニケーションの増加につながり、さらにパートナーの心理的ストレス反応の上昇とパートナーの生活満足感の低さにつながること、これらの関連は夫から妻、妻から夫のいずれの方向にも当てはまることが明らかになった。共働き夫婦のワーカホリズムに注目し、その影響が自己からパートナーへと至る心理社会的プロセスを大規模なカップルデータを用いて検討した本研究は、ワーカホリズムおよびワーク・ライフ・バランスに関する研究と実践に重要な示唆を与えるものと考えられる。(著者抄録)

© 2016 National Institute of Occupational Safety and Health. This study examined whether a higher level of psychological detachment during non-work time is associated with better employee mental health (Hypothesis 1), and examined whether psychological detachment has a curvilinear relation (inverted U-shaped pattern) with work engagement (Hypothesis 2). A large cross-sectional Internet survey was conducted among registered monitors of an Internet survey company in Japan. The questionnaire included scales for psychological detachment, employee mental health, and work engagement as well as for job characteristics and demographic variables as potential confounders. The hypothesized model was tested with moderated structural equation modeling techniques among 2,234 respondents working in the tertiary industries with regular employment. Results showed that psychological detachment had curvilinear relations with mental health as well as with work engagement. Mental health improved when psychological detachment increased from a low to higher levels but did not benefit any further from extremely high levels of psychological detachment. Work engagement showed the highest level at an intermediate level of detachment (inverted U-shaped pattern). Although high psychological detachment may enhance employee mental health, moderate levels of psychological detachment are most beneficial for his or her work engagement.
