Inclusion criteria were (P) adult female workers (over 18 years old), (E) presence of adverse psychosocial factors at work, (C) absence of adverse psychosocial factors at work, and (O) any menstrual cycle disorders, menstrual-related symptoms, or fertility issues.
Background: During the COVID-19 pandemic, health care professionals experienced high levels of depression. However, extant research has not highlighted effective internet-based psychological interventions to improve the mental health in this population during the pandemic. It remains unclear whether self-guided, internet-based cognitive behavioral therapy (iCBT) programs are effective in improving the mental health of health care workers during the COVID-19 pandemic.

Most previous studies were based on work hour regulations using more than 80 hours per week as an indicator of long working hours. We aimed to assess the association using a shorter indicator as the cut-off for long working hours among hospital doctors including senior doctors.

Objectives: This randomized controlled trial examined the effectiveness of a fully automated text-based stress management program, "WellBe-LINE," in improving mental health and job-related outcomes for employees in workplaces with fewer than 50 employees.
Background: This study aimed to examine whether online interactive communication education using video materials was as effective as face-to-face education among healthcare college students.
Methods: The participants were healthcare college students who were enrolled in study programs to obtain national medical licenses. They participated in lectures and exercises on healthcare communication, both online (n = 139) and face-to-face (n = 132).
Article Synopsis
- The text outlines the importance of participatory organizational interventions for improving psychosocial working conditions and highlights a lack of systematic reviews on their impact on mental health and work performance.
- The study aims to conduct a systematic review and meta-analysis using specific criteria (PICO) to evaluate the effects of these interventions, focusing on workers’ mental health and job performance.
- Researchers will search multiple electronic databases for relevant studies, independently assess study quality, and conduct statistical analyses to determine the overall effects and potential biases in the findings.
Objective/background: To clarify whether mobile sleep applications alleviate insomnia symptoms among adults from multi-community.
Patients/methods: A literature search was conducted using the PubMed, Cochrane, PsycINFO, and Web of Science databases for articles related to mobile technology and sleep interventions published between database inceptions and March 27, 2023. We pooled relevant data using a random-effects model, and a meta-analysis was performed using a web version of the Cochrane Review Manager.
Background: Although internet-based stress management programs are proven effective in improving mental health among workers, micro- and small-sized enterprises (MSEs), lacking in occupational healthcare services, face challenges implementing them. To address this gap, this study will develop the program with stakeholders at MSEs to aim for real-world implementation.
Objectives: This paper describes a study protocol for a pre-post feasibility study of an effectiveness-implementation hybrid type 2 trial of text-based internet-based programs ("WellBe-LINE") in MSEs with less than 50 employees.
Background: Depression and anxiety are the most common mental health issues experienced by workers. Although organizational intervention has been extensively evaluated as a primary prevention of depression and anxiety, the corresponding scientific evidence remains limited because of the lack of cluster randomized controlled trials (cRCT) and failure to detect organizational-level effects. Therefore, the present study aims to assess the preventive effects of four types of interventions on depression and anxiety among workers in an open, five-arm, parallel-group cRCT.

- The study focused on a new smartphone app called ASHARE designed to improve physical activity and reduce depression and anxiety among working individuals by using deep learning models for monitoring mental health based on physical activity levels.
- Researchers aimed to assess the app's effectiveness and its implementation outcomes, including user satisfaction and feasibility, through a month-long trial with employees aged 18 and older.
- Measurements included self-reported physical activity and psychological distress before and after using the app, with statistical analyses performed to evaluate changes and user experience compared to previous studies.
Objective: We aim to investigate the quantity and quality of scientific evidence dealing with comprehensive health issues of working women in occupational health.
Methods: This scoping review of original articles that investigated comprehensive health issues of working women aged 19-64 years in Japan was published in PubMed (1967-2022) and Igaku Chuo Zasshi (or Ichu-shi, 1982-2022). Using identical broad search terms, we first identified 17 122 English and 6154 Japanese articles.
Objectives: We examined the associations of perceived psychosocial safety climate (PSC) with psychological distress and work engagement in Japanese employees. We also examined the mediation effects of job demands (i.e.

Methods: A systematic literature search was conducted in PubMed, Embase, PsycINFO, PsycARTICLES, and the Japan Medical Abstracts Society database. Studies were eligible for inclusion if they examined associations between work-related psychosocial factors and inflammatory markers (interleukin-6, tumor necrosis factor-alpha, and C-reactive protein), used longitudinal or prospective cohort designs, were conducted among workers, were original articles written in English or Japanese, and were published up to 2017 for the first search, October 2020 for the second, and November 2022 for the third.
The Brief Job Stress Questionnaire (BJSQ) is used widely in occupational health studies and practice. Summarizing scientific production based on measurement is crucial. This study aimed to systematically review observational studies that used the BJSQ and the New BJSQ to show their usability.

- Participatory organizational interventions enhance occupational safety and health but lack a widely accepted definition, prompting a study to establish one.
- The researchers developed a draft definition based on existing literature and refined it through multiple discussions and feedback from 15 experts in occupational safety and health.
- The final proposed definition includes planned actions targeting working conditions to promote the well-being of all workers, emphasizing that ideally, all workers should be involved in all intervention steps, although elected representatives may participate in some cases.
Background: Digital data on physical activity are useful for self-monitoring and preventing depression and anxiety. Although previous studies have reported machine or deep learning models that use physical activity for passive monitoring of depression and anxiety, there are no models for workers. The working population has different physical activity patterns from other populations, which is based on commuting, holiday patterns, physical demands, occupations, and industries.

Article Synopsis
- Pregnancy discrimination is a common issue worldwide, impacting mothers' mental health during and after pregnancy, particularly contributing to postpartum depressive symptoms.
- A study of 285 Japanese women found that 23.9% experienced pregnancy discrimination, which was significantly linked to increased postpartum depressive symptoms, especially among non-regular (precarious) employees.
- Prenatal depressive symptoms were identified as a mediator in this relationship, accounting for over half of the impact of pregnancy discrimination on postpartum depression, highlighting the need for greater support for affected individuals.
Background: Compared to the numerous reports on mental health outcomes of workplace bullying victims, research on organizational outcomes of witnesses and physical health outcomes of victims and witnesses is scarce. Therefore, the purpose of this study was to investigate the relationship between bullying victimization and witnessing and various physical and mental health outcomes and organizational outcomes such as sickness absence, work performance, and job satisfaction.
Methods: This study used cross-sectional data from a nationally representative, community-based sample of 5,000 Japanese residents aged 20-60.
Introduction: Workplace environment, especially psychosocial factors at work such as job strain, workplace social support, and shift work, may affect the menstrual abnormalities and fertility of female workers. However, the association between psychosocial factors at work and menstrual abnormalities or fertility is not well understood. To address this relationship, we will conduct a systematic review and a meta-analysis of the literature that has utilized a longitudinal or prospective cohort design.
