© The Author(s) 2020. Backgroud and Aim: Community integration is an essential for people with mental illness that affects their health and quality of life. The objective of this study is to find the factors useful in improving community integration of people with mental illness. Methods: The study method was self-reporting questionnaires for people with mental illness living in the community. The decision tree analysis revealed that people with mental illness into high or low social isolation level strata. Multiple regression analyses stratified by using two social isolation levels were conducted. Results: Common factors among the strata were living environment of formal care accessibility and daily life activity. Specific factors for social isolation low-level stratum were self-efficacy for coping with symptoms, self-efficacy for social relationships, healthy lifestyle habits, treatment, exchange daily life information with friends and family members. Specific factors for social isolation high-level stratum were self-efficacy for daily living, self-efficacy for treatment-related behavior and satisfaction with formal care. All specific factors were positively associated with community integration. Conclusions: The findings suggest the devising interventions to enhance community integration by social isolation level among people with mental illness.

© 2019 John Wiley & Sons Ltd Aims: To clarify the subgroups of overtime work motivations and to determine how fatigue, mental status, and work engagement differ among the subgroups. Design: Cross-sectional. Methods: Questionnaires were distributed to 1,075 full-time nurses working in four hospitals in Japan from October 2015 - February 2016. Nurses were categorized into subgroups of overtime work motivation by latent class analysis. An analysis of covariance was conducted to examine how fatigue, mental status, and work engagement differ among subgroups. Results/Findings: We identified five types of overtime workers differing greatly in fatigue, mental status, and work engagement. Conclusions: Even when nurses worked approximately the same work hours, the difference in motivation corresponded to different degrees of fatigue, mental status, and work engagement. When introducing policies to reduce overtime work, managers should consider the different groups of overtime workers, as effective measures may differ.

© 2019 Background: It has been reported that transplant recipients are exposed to physical and psychosocial stresses even after transplant surgery and exhibit psychological disorders such as depression. Purpose: In this study, we extracted trends concerning how recipients of kidney transplants cope with stress, and we also examined how they cope with depression and its countermeasures. Method: We administered questionnaire surveys to 109 kidney transplant recipients. These included items on personal attributes, medical information, depression, and stress-coping type scales. Statistical analysis was performed using factor analysis and multiple regression analysis. Results: Fifteen out of 109 (13.8%) were found to be high-risk patients for depression based on responses to the questionnaire using the depression scale. We extracted 2 factors of stress-coping type, namely Factor 1, “Directly coping with the problem,” of patients who try to directly resolve the problem in a positive manner and Factor 2, “Stress-release while avoiding the problem,” for those who relieve their feelings in response to the stress without resolving the problem itself. When multiple regression analysis was conducted with the depression scale as the dependent variable and the stress-coping factor as the independent variable, Factor 1 tended to be associated with reduced depression and Factor 2 with increased depression. Conclusions: Results showed that to improve the mental health of those who receive kidney transplants, it is necessary to examine the depression and stress-coping types of such patients at an early stage and carry out education on stress-coping, focusing on resolving the actual problem.

© 2018 Nagayama et al. Purpose: The purpose of this pilot study was to determine the effectiveness and costs of the occupation-based practice for community dwelling frail elderly. Design: Pilot pre-post design without a control group. Setting: A care management center involving 37 local elderly. Subject: The final analysis included 26 frail elderly in a community dwelling center. Intervention: The intervention was occupation-based practice involving setting of client-centered goals, observation of real living situations, and provision of advice on the individual problem of real occupation. Outcome: The outcome was the Frenchay Activities Index (FAI), which is used to evaluate the instrumental activities of daily living (IADL). Additionally, the frequency, duration, and cost of the intervention were calculated. Results: Regarding the FAI score before and after the interventions, there were significant improvements in all items except work (P<0.05, effect size [r]: 0.67–0.93). A total of 15 people out of 26 (57.7%) showed improvement in activities of daily living. The frequency of interventions was 3.7 (95% confidence interval [CI]: 2.83–4.48), and the duration was 7.4 weeks (95% CI: 5.27–9.42). The average intervention cost was $258 (95% CI: 200.4–317.4). Conclusion: The results of this study showed that occupation-based practice has a potential to improve IADL in frail elderly, with low frequency of intervention, within a short-term, and direct cost reduction. We believe that this pilot study will contribute to future clinical studies for frail elderly, and the findings can be easily applied to daily clinical intervention. A well-designed prospective randomized-controlled trial is necessary to verify these results.

© 2018 John Wiley & Sons Ltd Aim and Background: Recent research has suggested that the reasons why nurses work overtime hours exert differential effects on the overall impact of the work. This study aimed to clarify why nurses work overtime, and whether well-being effects differed by reason, at both the ward and individual level. Methods: Participants were 1,075 permanent nurses from 54 wards. Overtime reasons’ distribution and impact on nurses were examined by a multilevel structural equation modelling approach. Results: Nurses typically worked overtime due to a pressure to conform, high workload and to enhance self-development. Involuntary overtime work demonstrated a detrimental effect on mental health and work engagement at both the ward and individual level, whereas voluntary overtime work exerted a beneficial effect on well-being. Conclusions: The distribution and impact of overtime work differed by the reasons for working the overtime. Implications for Nursing Management: These results suggest the importance of assessing the reasons for overtime, aside from the length of overtime hours. When trying to reduce overtime work, hospital managers and nurse managers need to advance the plan by ward as a whole, and also carefully assess the reasons for overtime.
