Psychiatric nursing is a stressful area of nursing practice. The purpose of this study was to examine occupational stress among psychiatric nurses in Japan. In this cross-sectional study, 238 psychiatric nurses were recruited from 7 hospitals. Data regarding the Generic Job Stress Questionnaire (GJSQ), the Center for Epidemiologic Studies for Depression Scale (CES-D), and the Health Practice Index (HPI) were obtained via self-report questionnaires. After adjusting for all the variables, CES-D scores were associated with job stress, but social support reduced the effect of stress on depression among psychiatric nurses. However, the interpretation of these results was hampered by the lack of data concerning important occupational factors, such as working position, personal income, and working hours. Further longitudinal investigation into the factors associated with depression may yield useful information for administrative and psychological interventions.

Background Perinatal depression is one of the important mental illnesses among women. However, not enough reviews have been done, and a certain consensus has not been obtained about the prevalence of perinatal depression among Japanese women. The purpose of our study is to reveal the reliable estimates about the prevalence of perinatal depression among Japanese women. Method We searched two databases, PubMed and ICHUSHI, to identify studies published from January 1994 to December 2017 with data on the prevalence of antenatal or postnatal depression. Data were extracted from published reports. Results We reviewed 1317 abstracts, retrieved 301 articles and included 123 studies. The point prevalence of postpartum depression at 1 month was 14.3% incorporating 108,431 Japanese women. The period prevalence of depression at pregnancy was 14.0% in the second trimester and 16.3% in the third trimester. The period prevalence of postpartum depression was 15.1% within the first month, 11.6% in 1–3 months, 11.5% in 3–6 months and 11.5% in 6–12 months after birth. We also identified that compared with multiparas, primiparas was significantly associated with a higher prevalence of postpartum depression; the adjusted relative risk was 1.76. Conclusions The prevalence of postpartum depression at 1 month after childbirth was found to be 14.3% among Japanese women. During pregnancy, the prevalence of depression increases as childbirth approaches, and the prevalence of depression was found to decrease in the postpartum period over time. In addition, we found that the prevalence of postpartum depression in primiparas was higher than that in multiparas. Hence, we suggest that healthcare professionals need to pay more attention to primiparas than multiparas regarding postpartum depression.

BackgroundOccupational stress among mental health nurses may affect their psychological health, resulting in reduced performance. To provide high-quality, sustainable nursing care, it is necessary to identify and control the factors associated with psychological health among mental health nurses. The purpose of this study was to examine the role of work–family conflict (WFC) in the well-known relationship between occupational stress and psychological health among mental health nurses in Japan.MethodsIn this cross-sectional study, data were gathered from 180 mental health nurses who had a coresident child or were married. Data from the Work–Family Conflict Scale, the Generic Job Stress Questionnaire, the Maslach Burnout Inventory-General Survey, and the Center for Epidemiologic Studies for Depression Scale were obtained via self-report questionnaires. The effects of occupational stress and WFC on psychological health were explored by hierarchical linear regression analysis.ResultsThe relationship between emotional exhaustion and occupational factors, including quantitative workload and the variance in workload, disappeared with the addition of WFC (each work interference with family [WIF] or family interference with work [FIW]). The relationship between emotional exhaustion and mental demands disappeared only with the addition of WIF. The relationship between depressive symptoms and variance in workload disappeared with the addition of WFC (each WIF or FIW).ConclusionOur findings may encourage hospital administrators to consider the risks of medical staff WFC. Furthermore, longitudinal investigations into the factors associated with WFC are required for administrative and psychological interventions.
