    Abstract INTRODUCTION Evidence is scarce regarding the role of menopause in age‐related cognitive function trajectories associated with increased depressive symptoms. We examined the longitudinal association among sex and age at menopause, depressive symptoms, and 2‐year follow‐up cognitive function. METHODS We used data from the English Longitudinal Study of Ageing, classifying age at menopause into three categories: < 40, 40 to 49, and ≥ 50 years. The study included 4726 women and 4286 men, using multilevel panel data regression to depict age trajectories. RESULTS Later menopause (≥ 50 years) was significantly associated with fewer depressive symptoms and better cognition than earlier menopause (< 40 years). Men showed significantly fewer depressive symptoms and worse cognition than women with later menopause. DISCUSSION Earlier menopause was significantly associated with worse 2‐year follow‐up cognition after adjusting for baseline depressive symptoms, cognition, and lifestyle factors. Dementia risk‐reduction strategies should consider women who undergo early menopause as a sex‐specific high‐risk group. Highlights Early menopause is associated with worse depressive symptoms and cognitive function. Early menopause is a high‐risk factor for cognitive decline and depressive symptoms. Menopause at < 40 years is linked to worse orientation and immediate and delayed recall. Men exhibit worse cognitive function than women experiencing late menopause.

    Abstract Objectives Cognitive impairment, pain and depressive symptoms are common and interrelated factors in older adults. However, the directionality and specificity of their association remains unclarified. This study explored whether these factors prospectively increase reciprocal risk and examined the longitudinal association between these factors and quality of life (QoL). Methods This study used longitudinal data from The Older Persons and Informal Caregivers Survey Minimal Data Set (TOPICS‐MDS; the Netherlands). Older adults self‐reported cognitive impairment, pain, depressive symptoms and QoL at baseline and after 6 and 12 months of follow‐up. The Random Intercept Cross‐Lagged Panel Model was used to assess the prospective association between the three factors, while a multilevel linear regression analysis in a two‐level random intercept model was used to examine the longitudinal associations between the three factors and QoL at the within‐person level. Results The data of 11,582 home‐dwelling older adults with or without subjective cognitive impairment were analysed. At the within‐person level, pain at 6 months was associated with subsequent depressive symptoms (β = 0.04, p = 0.024). The reverse association from depression to pain, and longitudinal associations between pain and subjective cognitive impairment and between depressive symptoms and subjective cognitive impairment were non‐significant. Pain, depressive symptoms and subjective cognitive impairment showed a significant association with poor QoL 6 months later. Conclusions A directional relationship was observed from pain to depressive symptoms. Pain reduction holds a potential benefit in the prevention of depressive symptoms, ultimately optimising the QoL of older adults.

    Abstract Background Interventions such as advance care planning (ACP), technology, or access to euthanasia may increase the sense of control over the end of life. In people with advanced dementia, the loss of cognitive and physical function limits the ability to control care. To date, little is known about the acceptability of these interventions from the perspective of persons with dementia and others involved. This study will examine the cross-cultural acceptability, and factors associated with acceptability, of four end-of-life interventions in dementia which contain an element of striving for control. Also, we report on the development and pilot testing of animation video vignettes that explain the interventions in a standardized manner. Methods Cross-sectional mixed-methods vignette study. We assess acceptability of two ACP approaches, technology use at the end of life and euthanasia in persons with dementia, their family caregivers and physicians in six countries (Netherlands, Japan, Israel, USA, Germany, Switzerland). We aim to include 80 participants per country, 50 physicians, 15 persons with dementia, and 15 family caregivers. After viewing each animation video, participants are interviewed about acceptability of the intervention. We will examine differences in acceptability between group and country and explore other potentially associated factors including variables indicating life view, personality, view on dementia and demographics. In the pilot study, participants commented on the understandability and clarity of the vignettes and instruments. Based on their feedback, the scripts of the animation videos were clarified, simplified and adapted to being less slanted in a specific direction. Discussion In the pilot study, the persons with dementia, their family caregivers and other older adults found the adapted animation videos and instruments understandable, acceptable, feasible, and not burdensome. The CONT-END acceptability study will provide insight into cross-cultural acceptability of interventions in dementia care from the perspective of important stakeholders. This can help to better align interventions with preferences. The study will also result in a more fundamental understanding as to how and when having control at the end of life in dementia is perceived as beneficial or perhaps harmful. Trial registration The CONT-END acceptability study was originally registered at the Netherlands Trial Register (NL7985) at 31 August, 2019, and can be found on the International Clinical Trials Registry Platform.

    Background Neuropsychiatric symptoms occur frequently in many nursing home residents with dementia. Despite the availability of multidisciplinary guidelines, neuropsychiatric symptoms are often inadequately managed. Three proven effective methods for managing neuropsychiatric symptoms were integrated into a single intervention method: the STIP-Method, a personalized integrated stepped-care method to prevent and treat neuropsychiatric symptoms. The STIP-Method comprises 5 phases of clinical reasoning to neuropsychiatric symptoms and 4 stepped-care interventions and is supported with a web application. Objective This study aims to identify the facilitators and barriers in the implementation of the STIP-Method in nursing homes. Methods A mixed methods design within a participatory action research was used to implement the STIP-Method in 4 facilities of 2 Dutch nursing home organizations. In total, we aimed at participation of 160-200 persons with dementia and expected an intervention fidelity of 50% or more, based on earlier studies regarding implementation of effective psychosocial interventions to manage neuropsychiatric symptoms. All involved managers and professionals were trained in the principles of the STIP-Method and in using the web application. An advisory board of professionals, managers, and informal caregivers in each facility supported the implementation during 21 months, including an intermission of 6 months due to the COVID-19 pandemic. In these 6-weekly advisory board meetings, 2 researchers stimulated the members to reflect on progress of the implementation by making use of available data from patient records and the web application. Additionally, the 2 researchers invited the members to suggest how to improve the implementation. Data analysis will involve (1) analysis of facilitators and barriers to the implementation derived from verbatim text reports of advisory board meetings to better understand the implementation process; (2) analysis of patient records in accordance with multidisciplinary guidelines to neuropsychiatric symptoms: personalized, interdisciplinary, and proactive management of neuropsychiatric symptoms; (3) evaluation of the web application in terms of usability scores; (4) pre- and postimplementation analysis of patient records and the web application to evaluate the impact of the STIP-Method, such as changes in neuropsychiatric symptoms and informal caregiver burden. Results We enrolled 328 persons with dementia. Data collection started in July 2019 and ended in December 2021. The first version of this manuscript was submitted in October 2021. The first results of data analysis are expected to be published in December 2022 and final results in June 2023. Conclusions Our study may increase understanding of facilitators and barriers to the prevention and treatment of neuropsychiatric symptoms in nursing home residents with dementia by implementing the integrated STIP-Method. The need for well-designed implementation studies is of importance to provide nursing homes with optimal tools to prevent and treat neuropsychiatric symptoms.

    Background: Japan has one of the highest percentages of persons with dementia and hospital deaths in the world. Hospitals are often not equipped to handle the care complexity required for persons with dementia at the end of life. The National Dementia Orange plan aimed to decrease hospital deaths by expanding time in the community. Objective: The aim of this study is to evaluate whether the National Dementia Orange Plan is associated with a decrease in hospitals deaths for persons with dementia. Methods: We used quarterly, cross-sectional, national death certificate data consisting of the total Japanese dementia population 65 years and older, spanning a period from 2009 to 2016. The primary outcome was quarterly adjusted relative risk rates (aRRR) of dying in hospital, nursing home, home, or elsewhere. An interrupted time series analysis was performed to study the slope change over time. Analyses were adjusted for sex and seasonality. Results: 149,638 died with dementia. With the implementation of the Orange Plan, death in nursing home (aRRR 1.08, [1.07–1.08], p < 0.001) and elsewhere (aRRR 1.05, [1.05–1.06], p < 0.001) increased over time compared to hospital death. No changes were found in death at home. Conclusion: This study provides evidence that the National Dementia Orange plan was associated with a small increase in death in nursing home and elsewhere. Hospital death remained the primary location of death. End-of-life strategies should be expanded in national dementia policies to increase aging in the community until death.

    Abstract Aims First-year postpartum depression is a common mental health problem among first-time mothers. A younger age of pregnancy often compounds the challenge due to underlying factors such as poverty and limited educational achievement. This study aimed to examine the minimal number of interpersonal supporters during pregnancy associated with lower levels of postpartum depressive symptoms among first-time mothers. Methods We obtained data from the population-based Mother–Infant/Newborn Tokyo Cohort (MINT cohort) in four municipalities in Tokyo on 429 first-time mothers who responded to two waves of surveys (early pregnancy and one month postpartum). They completed self-report measures of interpersonal support using one item from the Social Support Questionnaire and depressive symptoms using the Edinburgh Postnatal Depression Scale. Segmented regression analyses were conducted to determine the threshold at which the strength of the association changed between the number of interpersonal supporters and postpartum depressive symptoms, with adjustment for depressive symptoms in pregnancy. This analysis was also conducted with the sample stratified into young mothers (≤ 25 years) and older mothers (≥ 26 years). Results In the overall sample, postpartum depressive symptoms were found to be lower among individuals with more than 3.0 supportive individuals (prepartum). Among young mothers, this threshold was higher, with lower symptom levels observed among those with at least 5.3 supporters. Only 22.9% of young first-time mothers had this level of interpersonal support, compared to 54.8% of all first-time mothers. Conclusions Our results suggest that having four or more interpersonal supporters in early pregnancy is associated with lower levels of postpartum depressive symptoms among first-time mothers. Additionally, among young mothers, having six or more supporters was associated with lower postpartum depressive symptoms. These findings suggest that tailored strategies to increase supporters around first-time pregnant women might be beneficial depending on their age.

    Japan, a super-aging society, faces a native care worker shortage and increased demand for foreign-born care workers (FBCWs) in geriatric care facilities. We investigated factors influencing native care workers’ concerns and reluctance toward accepting FBCWs in Japan from four areas. Native care workers ( N = 1060) in 10 geriatric care facilities (response rate = 71%), recruited using convenience sampling considering the regional job vacancies, responded to a self-report questionnaire survey. After excluding ineligible data (e.g., for day-care facilities) or missing data, the analysis included 589 participants (67.2% women, M age = 42.63 ± 12.16 years). Results indicated that facilities not accepting FBCWs had significant concerns about managerial positions and job stress. Native care workers with concerns about accepting FBCWs and those working 50+ hours per week were three times more reluctant to accept FBCWs. However, ethical leadership reduced this reluctance. Therefore, facility employers in aging countries must address native care workers’ concerns and ensure workplace improvement before hiring FBCWs.

    Abstract Background There is limited quantitative evidence regarding good death for people with dementia. Aims To clarify which components of good death are important for people with dementia and to identify the component structure of good death through explanatory factor analysis. Design A web‐based questionnaire survey was conducted where bereaved family members and professionals were asked to rate the importance of the 44 items identified from previous qualitative interviews as components of ‘good death’. Setting/participants A total of 618 bereaved family members of people with dementia, and 206 physicians, nurses and care workers, each, involved in dementia care. Results A total of 1236 participant responses were analyzed. The exploratory factor analysis identified the following four factors as the concepts of good death for people with dementia: ‘Comfort, security, and safety’, ‘Relationships’, ‘Independence’, and ‘Personhood care’. The top five items that bereaved families indicated as important were ‘dying at peace’ (97%), ‘being free from pain and physical distress’ (97%), ‘being calm’ (96%), ‘being clean’ (96%), and ‘receiving necessary daily living assistance’ (96%). The items with the lowest scores were ‘being cared for by family’ (53%), ‘living with faith’ (54%), and ‘remaining in people's memory after one's death’ (67%). We found only small differences between the opinions of the bereaved family members and medical professionals. Conclusions The components of good death which stakeholders consider important provide useful information for developing care implementation strategies for dying people with dementia.

    Abstract Background and Hypothesis Problematic internet use (PIU) is prevalent among adolescents. Past research suggested cross-sectional associations between PIU and psychotic experiences, but little information is available on the longitudinal association. We hypothesized that PIU in adolescence may be longitudinally associated with psychotic experiences, adjusting for confounders. Study Design We analyzed a random sample of adolescents in the Tokyo Teen Cohort to examine how PIU at ages 10 (2012–2015), 12 (2014–2017), and 16 (2019–2021) was associated with mental health issues at age 16. PIU was evaluated by the modified Compulsive Internet Use Scale, psychotic experiences by the Adolescent Psychotic-like Symptom Screener, and depression by the Short Mood and Feelings Questionnaire. We also examined the mediating role of social withdrawal. Study Results We analyzed 3171 adolescents; 151 reported psychotic experiences and 327 reported depression at age 16. Compared with the lowest tertile PIU group, the highest tertile PIU group at age 12 showed an increased adjusted risk of psychotic experiences (RD 3.3%, 95% CI 2.9%–3.7%; RR 1.65, 95% CI 1.55–1.73) and depression (RD 5.9%, 95% CI 5.5%–6.3%; RR 1.61, 95% CI 1.55–1.68) at age 16. PIU at age 16 showed analogous results, while PIU at age 10 suggested a smaller impact. Social withdrawal mediated 9.4%–29.0% of the association between PIU and psychotic experiences. Conclusions PIU is longitudinally associated with psychotic experiences and depression in adolescents. Further longitudinal and intervention studies are warranted to provide robust public health implications and foster a safer digital future.

    Background: The emotional impact of the coronavirus disease 2019 (COVID-19) pandemic on people with dementia has been quantified. However, little is known about the impact of change in home-care use owing to the pandemic. Objective: To determine the longitudinal association between dementia, change in home-care use, and depressive symptoms during the pandemic. Methods: We included data of 43,782 home-dwelling older adults from the English Longitudinal Study of Ageing (ELSA), Study of Health, Ageing and Retirement in Europe (SHARE), and National Health and Aging Trends Study (NHATS). This study considered the latest main wave survey prior to the pandemic as the baseline, and the COVID-19 survey as follow-up. In a series of coordinated analyses, multilevel binomial logistic regression model was used to examine the association between baseline dementia, change in home-care use at follow-up, and presence of depressive symptoms. Results: Dementia, using the ELSA, SHARE, and NHATS datasets, was identified in 2.9%, 2.3%, and 6.5% of older adults, and home-care use reduced in 1.7%, 2.8%, and 1.1% of individuals with dementia, respectively. Dementia was significantly associated with the increased risk of depressive symptoms in all three cohorts. However, the interaction between dementia and period (follow-up) was non-significant in SHARE and NHATS. Across all three cohorts, home-care use during the pandemic, regardless of change in amount, was significantly associated with increased depressive symptoms, compared to the non-use of home care. Conclusions: These results highlight the need for tailoring dementia care at home to promote independence and provide sustainable emotional support.

    Objectives This study aimed to determine best practices for involving family caregivers in interventions aimed at preventing and reducing responsive behaviour stemming from unmet needs, including pain. Design Scoping review, reported according to the Preferred Reporting Items for Systematic Reviews, Meta-Analyses extension for Scoping Reviews reporting guideline. Data sources PubMed, Embase, Emcare, Web of Science, COCHRANE Library, PsycINFO, Academic Search Premier and Cinahl searched up to 23 July 2023. Eligibility criteria Studies reporting on family involvement in interventions for nursing home residents with dementia were included. Data extraction and synthesis Two researchers independently extracted the data, followed by a content analysis. Results Of the 1486 records screened, 20 studies were included. Family caregivers were involved in interventions aimed at planning care, life review (eg, documentation of life experiences of their relative), and selecting activities for their relative. Family caregivers preferred an active role in developing optimal care for their relative. Drivers of success and barriers to family involvement centred around three themes: (1) communication between all involved; (2) prerequisites (organisational and other conditions) and (3) personal circumstances (family’s coping and skills). Conclusion Best practices for involving family caregivers in interventions aimed at addressing responsive behaviour in residents with dementia concerned those interventions in which family caregivers were given an important role in managing responsive behaviour. This means that, in order to achieve an active role of family caregivers in the whole care process, their needs must be taken into account.

    AIMS: This study aimed to conduct a systematic review of studies on the outcomes of long-term hospitalisation of individuals with severe mental illness, considering readmission rates as the primary outcome. METHODS: Studies considered were those in which participants were aged between 18 and 64 years with severe mental illness; exposure to psychiatric hospitals or wards was long-term (more than one year); primary outcomes were readmission rates; secondary outcomes were duration of readmission, employment, schooling, and social participation; and the study design was either observational or interventional with a randomised controlled trial (RCT) design. Relevant studies were searched using MEDLINE, PsycINFO, Web of Science, CINAHL, and the Japan Medical Abstract Society. The final search was conducted on 1 February 2022. The risk of bias in non-randomised studies of interventions was used to assess the methodological quality. A descriptive literature review is also conducted. RESULTS: Of the 11,999 studies initially searched, three cohort studies (2,293 participants) met the eligibility criteria. The risk of bias in these studies was rated as critical or serious. The 1-10 years readmission rate for patients with schizophrenia who had been hospitalised for more than one year ranged from 33 to 55%. The average of readmission durations described in the two studies was 70.5 ± 95.6 days per year (in the case of a 7.5-year follow-up) and 306 ± 399 days (in the case of a 3-8-year follow-up). None of the studies reported other outcomes defined in this study. CONCLUSIONS: The readmission rates in the included studies varied. Differences in the follow-up period or the intensity of community services may have contributed to this variability. In countries preparing to implement de-institutionalisation, highly individualised community support should be designed to avoid relocation to residential services under supervision. The length of stay for readmissions was shorter than that for index admissions. The results also imply that discharge to the community contributes to improved clinical outcomes such as improved social functioning. The validity of retaining patients admitted because of the risk of rehospitalisation was considered low. Future research directions have also been discussed.

    Background: The coronavirus disease (COVID-19) pandemic has challenged palliative end-of-life care for people with dementia. The site of death can be considered as an end-of-life care quality indicator. Most people with dementia prefer to die at nursing or private homes; however, in Japan, they are often hospitalized in psychiatric hospitals for management of neuropsychiatric symptoms. As palliative end-of-life care for older adults with Alzheimer’s disease and related dementias has been further challenged by the COVID-19 pandemic, little is known about its effects on the place of death in patients with dementia. Objectives: This study aimed to investigate the shifts in place of death from dementia during the COVID-19 pandemic in Japan. Changes throughout the pandemic were compared between deaths from dementia and from senility. Design: Cross-sectional. Methods: Death certificate data of individuals aged 65 years or older who died in Japan between 1 January 2018, and 31 December 2021, were used to extract the cause and place of death. Differences in place of death between the periods were estimated using multinomial logistic analysis with reference to death in private homes. Results: Deaths from dementia mostly occurred in hospitals (59%), while deaths from senility were most frequent in nursing homes (37%). After adjusting for patient characteristics, the likelihood of hospital deaths significantly increased for patients with dementia during the pandemic. Meanwhile, the likelihood of senility deaths decreased in hospitals but increased in nursing homes during the pandemic. Conclusion: The shift to hospital deaths since the onset of the COVID-19 pandemic was uniquely observed in deaths from dementia. This hospital shift likely involved increased transfers from nursing and private homes to psychiatric hospitals. Further investigation is needed to examine the association between the pandemic-related change in long-term care workforce and palliative care practice in people with dementia.

    There is growing evidence of the impact of informal caregiving on adolescent mental health, and its role is often hidden unintentionally or intentionally, which may hamper early identification and support for young informal caregivers. However, the quantitative evidence regarding household factors relating to informal caregiving has mostly been based on cross-sectional findings. This study examines the longitudinal associations between household characteristics and the duration of informal caregiving in adolescents from 10 to 16 years of age. Child–household respondent pairs (n = 2331) from the Tokyo Teen Cohort in Japan were followed every 2 years from 10 to 16 years of age. Informal caregiving was assessed repeatedly based on the household respondent’s survey responses. Persistent caregiving was defined as daily caregiving at two or more waves. There were 2.2% of children who gave daily care at two or more waves. Cross-sectional associations with daily informal caregiving at each wave were found with girls, low household income, and cohabiting with grandparents. A significant association with persistent caregiving was found only in cohabiting with grandparents at 10 years of age after adjusting for sex, number of siblings, single parent, and household income. Our longitudinal examination highlighted cohabiting with grandparents as a preceding factor for persistent caregiving. Identification and support for young informal caregivers should be integrated into social care service systems for older adults. The mechanism of persistent caregiving requires clarification.

    This study examined the longitudinal association between dementia, activity participation, the coronavirus disease 2019 pandemic period, and 1-year mental health changes. We obtained data from the National Health and Aging Trends Study in the United States. We included 4,548 older adult participants of two or more survey rounds between 2018 and 2021. We identified baseline dementia status, and assessed depressive symptoms and anxiety at baseline and follow-up. Dementia and poor activity participation were independently associated with an increased prevalence of depressive symptoms and anxiety. Dementia care and support should address emotional and social needs under continued public health restrictions.

    Objectives Advance care planning (ACP) is an increasing priority for people with dementia during the COVID-19 pandemic. This study evaluated the association between ACP initiation and depressive symptoms among home-dwelling people living with dementia. Methods An internet-based questionnaire survey was conducted with Japanese family caregivers of home-dwelling persons with dementia in June 2021. Family caregivers evaluated the level of depressive symptoms in persons with dementia using the Neuropsychiatric Inventory (NPI). Caregivers also rated the quality of life of persons with dementia using the EQ-5D-5L. Results A total of 379 family caregivers participated in the survey. Depressive symptoms were reported in 143 persons with dementia (37.7%). A total of 155 persons with dementia (40.9%) had initiated ACP, of which 88 (56.8%) had care professionals involved in ACP conversation. After adjusting for the characteristics of persons with dementia and caregivers, persons with professional involvement showed significantly more severe depressive symptoms compared to those who did not initiate ACP. There was no significant difference in the quality of life of persons with dementia according to ACP initiation. Conclusions Many home-dwelling persons with dementia experienced depressive symptoms during the COVID-19 pandemic, especially in cases where care professionals were involved in ACP conversations. Optimal and proactive ACP approaches need to be developed to prevent depressive symptoms in newly diagnosed persons.

    Abstract Background and Hypotheses A wealth of evidence suggests that adolescent psychotic experiences (PEs), and especially auditory hallucinations (AHs), are associated with an increased risk for self-injurious behavior (SIB). However, the directionality and specificity of this association are not well understood, and there are no published studies investigating within-person effects over time. The present study aimed to test whether AHs and SIB prospectively increase reciprocal risk at the individual level during early-to-middle adolescence. Study Design Three waves (12y, 14y, and 16y) of self-reported AHs and SIB data from a large Tokyo-based adolescent birth cohort (N = 2825) were used. Random Intercept Cross-Lagged Panel Model (RI-CLPM) analysis was conducted to test the within-person prospective associations between AHs and SIB. Study Results At the within-person level, AHs were associated with subsequent SIB over the observation period (12y–14y: β = .118, P < .001; 14–16y: β = .086, P = .012). The reverse SIB->AHs relationship was non-significant at 12–14y (β = .047, P = .112) but emerged from 14y to 16y as the primary direction of influence (β = .243, P < .001). Incorporating depression as a time-varying covariate did not meaningfully alter model estimates. Conclusions A complex bi-directional pattern of relationships was observed between AHs and SIB over the measurement period, and these relationships were independent of depressive symptoms. Adolescent AHs may be both a predictor of later SIB and also a manifestation of SIB-induced psychological distress.

    N-acetylcysteine (NAC) is an antioxidant that prevents tumor necrosis factor (TNF)-α-induced cell death, but it also acts as a pro-oxidant, promoting reactive oxygen species independent apoptosis. Although there is plausible preclinical evidence for the use of NAC in the treatment of psychiatric disorders, deleterious side effects are still of concern. Microglia, key innate immune cells in the brain, play an important role in inflammation in psychiatric disorders. This study aimed to investigate the beneficial and deleterious effects of NAC on microglia and stress-induced behavior abnormalities in mice, and its association with microglial TNF-α and nitric oxide (NO) production. The microglial cell line MG6 was stimulated by Escherichia coli lipopolysaccharide (LPS) using NAC at varying concentrations for 24 h. NAC inhibited LPS-induced TNF-α and NO synthesis, whereas high concentrations (≥30 mM) caused MG6 mortality. Intraperitoneal injections of NAC did not ameliorate stress-induced behavioral abnormalities in mice, but high-doses induced microglial mortality. Furthermore, NAC-induced mortality was alleviated in microglial TNF-α-deficient mice and human primary M2 microglia. Our findings provide ample evidence for the use of NAC as a modulating agent of inflammation in the brain. The risk of side effects from NAC on TNF-α remains unclear and merits further mechanistic investigations.

    AIM: This study evaluated an online mental health literacy intervention to improve help-seeking for psychosis amongst parents of adolescents. METHODS: A total of 2496 parents of first-grade junior high school students, recruited from a Japan-based survey company, participated in a randomized controlled trial in July 2016; participants were randomly allocated to the intervention (n = 1248) or control group (n = 1248). They were assessed at baseline and one-week post intervention. The intervention group received a 30-minute online educational programme that included a narrative of the mother of an adolescent with psychosis. RESULTS: There were no between-group differences in changes in the rate of 'no help-seeking' in any hypothetical situations of a child's psychosis and prodromal symptoms. CONCLUSIONS: The intervention might have been suboptimal to improve mental health literacy for psychosis amongst parents of adolescents. A narrative message from a service user may be helpful to encourage parents in help-seeking.

    Abstract Background Adolescent loneliness is a growing public health issue owing to its adverse health impact. Although adolescent loneliness is common, its trajectories can show distinct patterns over time. However, there is limited knowledge regarding their determinants, particularly for chronic loneliness. We aimed to determine the predictors of loneliness trajectories across early-to-mid adolescence and examine their association with later suicidality. Methods Data were collected from 3165 participants from the population-based Tokyo Teen Cohort. Participants reported their loneliness at 10, 12, 14, and 16 years. Loneliness trajectories were identified using latent class growth analysis. We examined the predictive role of bullying victimization and parental psychological distress at age 10 via a multinomial logistic regression. Sociodemographic and child-related factors (i.e., chronic health conditions and cognitive delay) were included as covariates. The association between the trajectories, self-harm, and suicidal ideation by age 16 was investigated using Poisson regression. Results Four trajectories were identified: “consistently low” (2448, 77.3%), “moderate–decreasing” (185, 5.8%), “moderate–increasing” (508, 16.1%), and “consistently high” (24, 0.8%). Taking “consistently low” as a reference, experiences of bullying victimization predicted all the remaining trajectories [adjusted relative risk ratio 1.64, 95% confidence interval (CI) 1.18–2.28 for “moderate–decreasing,” 1.88, 1.52–2.33 for “moderate–increasing,” and 4.57, 1.97–10.59 for “consistently high”]. Parental psychological distress predicted the “moderate–increasing” (1.84, 1.25–2.71) and “consistently high” (5.07, 1.78–14.42) trajectories. The “consistently high” trajectory showed the greatest risk for self-harm and suicidal ideation (adjusted relative risk ratio 6.01, 95% CI 4.40–8.22; 2.48, 1.82–3.37, respectively); however, the “moderate–increasing” and “moderate–decreasing” trajectories were also at increased risk (moderate–increasing: 2.71, 2.23–3.30 for self-harm, 1.93, 1.69–2.19 for suicidal ideation; moderate–decreasing: 2.49, 1.91–3.26 for self-harm, 1.59, 1.33–1.91 for suicidal ideation). Conclusions Bullying victimization and parental psychological distress at age 10 were independent determinants of increased and chronic loneliness trajectories across early-to-mid adolescence. Compared with “consistently low,” all other loneliness trajectories were associated with an increased risk of adolescent suicidality. Interventions targeting adolescent loneliness should include approaches to mitigate bullying and parental psychological distress. These strategies may help prevent adolescent suicidality.

    This study estimated the excess suicidal mortality during the COVID-19 pandemic in Japan. A Poisson regression model was used to assess the association between unemployment rates, expenditure for alcohol, eating out, and suicide, from January 2008 to March 2020. The excess suicidal mortality was assessed by applying the identified model to data from April 2020 to December 2021. The number of estimated excess deaths during COVID-19 was 3397 in men and 2390 in women. COVID-19 may have caused unprecedented psychological distress among people, owing to restricted social gatherings and prolonged uncertainties.

    BACKGROUND: Middle-aged adults may be the ideal target group for dementia-related stigma reduction interventions to encourage the utilization of services among those who may become family caregivers. Neighborhood social cohesion may diminish dementia-related stigma, particularly in terms of perceived public attitudes. The COVID-19 pandemic can further negatively impact perceived public stigma. OBJECTIVE: To investigate the association between neighborhood social cohesion and dementia-related stigma during the pre- and current COVID-19 period. METHODS: We employed a cross-sectional design using data from a large population-based cohort, the Tokyo Teen Cohort, in Japan. Overall, 2,469 mothers of 16-year-old adolescents self-completed a questionnaire comprising nine dementia-related stigma questions evaluating perceived public and personal attitudes. Neighborhood social cohesion was assessed using a five-item instrument. The participants were divided into two groups according to the time of assessment: prior to the pandemic's onset (February 2019-March 2020) and during the pandemic (April 2020-July 2021). A multiple regression analysis of stigma was performed using neighborhood social cohesion as an independent variable, and caring experience, age, educational level, and working status as covariates. RESULTS: Personal and perceived public stigma were significantly lower in participants who perceived greater neighborhood social cohesion. However, level of personal and perceived public stigma did not differ between pre- and during the pandemic period. CONCLUSION: Neighborhood social cohesion may be a modifiable factor for dementia-related stigma. A localized intervention to enhance social cohesion in the neighborhood community would promote the utilization of services among those who may become family caregivers.

    Background The COVID-19 pandemic has triggered stigmatic attitudes against health care workers. Some forms of social media may play a role in disseminating stigmatizing messages. Objective We aimed to investigate the association between COVID-19 information sources and stigma against health care workers among college students during the pandemic. Methods A cross-sectional, observational study was conducted using a web-based platform in the Tohoku region of Japan. College students aged ≥20 years were asked to complete the questionnaire between August 18 and October 31, 2020. Stigma against health care workers was evaluated using a modified Japanese version of the Social Distance Scale. Participants were also asked to rate their perceived vulnerability to infection using the Japanese version of the Perceived Vulnerability to Disease scale. Results A total of 281 students from 8 colleges completed the web-based survey. There were 139 (49.5%) participants who used Twitter, 187 (66.5%) who used news websites, and 46 (16.4%) who used the websites of public health agencies as COVID-19 information sources. After adjusting for age, sex, department, and Perceived Vulnerability to Disease scores, the level of stigma did not differ between students who used Twitter and those who did not. Students who used the websites of public health agencies showed a significantly less stigmatic attitude than those who did not. Conclusions Fact-checking and directing visitors to credible information sources from public health agencies may have prevented the formation of stigmatic attitudes toward health care workers. An effective strategy to enable easy access to information provided by public agencies should be integrated into widespread web-based platforms.

    AIM: Restrictions such as physical distancing and online learning for college students were implemented due to the COVID-19 pandemic. Owing to this, students may experience psychological distress from social isolation and loneliness. Nursing students are subjected to an exacerbated level of distress during the pandemic due to their role as health professionals. Therefore, the present study aimed to investigate the level of anxiety and depression among Japanese nursing students, according to their perceived vulnerability to COVID-19. METHODS: A total of 281 college students (104 nursing students and 177 other college students) responded to a web-based anonymous questionnaire survey from 18 August to 31 October 2020. The Hospital Anxiety and Depression Scale was used to evaluate anxiety (HADS-A) and depression (HADS-D). Perceived vulnerability to COVID-19 was assessed using the Perceived Vulnerability to Disease Scale. RESULTS: In both groups of students, the prevalence of both anxiety (30.5% in nursing students; 69.5% in others) and depressive symptoms (31.1% in nursing students; 68.9% in others) were remarkably high. There were no significant differences in anxiety and depression between nursing and other students after adjusting for perceived vulnerability to COVID-19 plus socio-demographic characteristics and stress coping styles. Perceived vulnerability and its interactions with nursing did not show a significant association with either depression or anxiety. CONCLUSION: This study highlights the need for greater support and preventive strategies for mental health problems for college students during the COVID-19 pandemic regardless of perceived vulnerability.

    Abstract Background The importance of advance care planning for people with dementia has increased during the Coronavirus Disease 2019 Pandemic. However, family caregivers may have concerns about having conversations regarding advance care planning with their loved ones, which may hinder the initiation of such planning. This study investigated family caregivers’ concerns regarding conducting advance care planning for home-dwelling individuals with dementia. Methods A prospective cross-sectional study compared the level of family-caregiver concern between those who had initiated advance care planning and those who did not. In June 2021, an internet-based questionnaire survey was administered to Japan-based family caregivers of persons with dementia. Registered members of a Japan-based survey company were recruited; inclusion criteria were being aged 40 years or older and having been a primary, non-professional caregiver of a family member with dementia. Respondents rated their level of agreement with six statements regarding advance-care-planning-related concerns. Respondents also reported their psychological well-being using the WHO-5 Well-Being Index. Results Overall, 379 family caregivers participated in this survey. Of these, 155 (40.9%) reported that their loved ones had initiated advance care planning, of whom 88 (56.8%) stated that care professionals were involved in the advance-care-planning conversations. The level of family-caregiver concern was significantly lower when the loved one initiated the conversation concerning advance care planning. After adjusting for the characteristics of persons with dementia and their caregivers, family caregivers with lower psychological well-being showed significantly higher levels of concern. Conclusions Family caregivers reported concerns regarding conducting advance care planning. There is a need for educational and clinical strategies that encourage professionals to address the psychological needs of family caregivers.

    Abstract Background Research on the nature of a “good death” has mostly focused on dying with cancer and other life-limiting diseases, but less so on dementia. Conceptualizing common cross-cultural themes regarding a good end of life in dementia will enable developing international care models. Methods We combined published qualitative studies about end of life with dementia, focus group and individual interviews with the researchers, and video-conferencing and continuous email discussions. The interviews were audio-recorded and transcribed verbatim. The data were analyzed thematically, and the researchers developed common themes referring to their original studies. Results Fourteen qualitative researchers representing 14 cross-cultural studies covering qualitative data of 121 people with dementia and 292 family caregivers. The researchers and data were from eight countries UK, The Netherlands, Japan, Portugal, Germany, Canada, Brazil, and Ireland. Three focus groups, five individual interviews, and video-conferencing were conducted and feedback on multiple iterations was gained by 190 emails between May 2019 and April 2020 until consensus was achieved. Nine cross-culturally common themes emerged from the discussions and shared interpretation of the data of persons with dementia and family caregivers. Three represent basic needs: “Pain and Symptoms Controlled,” “Being Provided Basic Care,” and “A Place like Home.” Other themes were “Having Preferences Met,” “Receiving Respect as a Person,” “Care for Caregivers,” “Identity Being Preserved,” “Being Connected,” and “Satisfaction with Life and Spiritual Well-being.” “Care for Caregivers” showed the greatest difference in emphasis across cultures. Good relationships were essential in all themes. Conclusions The common cross-cultural themes comprise a framework underpinned by value placed on personhood and dignity, emphasizing that interdependency through relationships is essential to promote a good end of life with dementia. These themes and valuing the importance of relationships as central to connecting the themes could support care planning and further development of a dementia palliative care model.

    Background Attention-deficit/hyperactivity disorder (ADHD) develops in early childhood and carries lifelong impact, but early identification and intervention ensure optimal clinical outcomes. Prolonged or excessive parenting stress may be a response to infant behavioral differences antecedent to developmental disorders such as ADHD, and therefore represents a potentially valuable inclusion in routine early-life assessment. To investigate the feasibility of using routinely-collected self-reported maternal parenting stress as a risk marker for child ADHD, this study investigated the longitudinal association between maternal parenting stress from 1 to 36 months after childbirth and child ADHD in early adolescence. Methods The sample comprised 2,638 children (1,253 girls) from the Tokyo Teen Cohort population-based birth cohort study. Mothers recorded parenting stress five times from 1 to 36 months following childbirth in the Maternal and Child Health Handbook, a tool used for routine early-life assessment in Japan. Nine years later, mothers evaluated their child's ADHD symptoms at 12 y using the hyperactivity/inattention subscale from the Strength and Difficulties Questionnaire. Results Approximately 7.5% of parents reported that they had parenting stress at 36 m after childbirth. 6.2% of children were evaluated as above the cut-off for ADHD symptoms at 12 y. Parenting stress at 1 and 3–4 m was not associated with child ADHD symptoms at 12 y. However, child ADHD symptoms at 12 y was significantly associated with parenting stress at 9–10 m (unadjusted OR = 1.42, p =.047, 95% CI [1.00, 2/00]), 18 m (unadjusted OR = 1.57, p =.007, 95% CI [1.13, 2.19]) and 36 m (unadjusted OR = 1.67, p =.002, 95% CI [1.20, 2.31]). These associations remained after adjustment for child's sex, age in months and family income. Conclusions We identified associations between parenting stress at 9–10, 18 and 36 m after childbirth and child ADHD symptoms at 12 years old. Self-reported parenting stress data may have utility as an early indicator for ADHD risk. Participation in early-life health checks, assessment of parenting stress, and tailoring support to family needs should be promoted for early identification and intervention for ADHD.

    Objectives Perceived capacity denotes a subjective sense of having resources to cope with strains and hardships, and hence maternal perceived capacity may be protective against risk factors for child maltreatment. This study investigated the longitudinal association between maternal perceived capacity in life and child maltreatment. Design This population-based longitudinal study used self-reported questionnaires from the Tokyo Teen Cohort study (TTC), a large community-based cohort study conducted in Japan between 2014 and 2019. Setting Mother–child pairs were randomly recruited from the resident registries of three municipalities in Tokyo, Japan. Methods A total of 2515 mothers participated. Mothers’ perceived capacity in life was evaluated using the self-reported TTC wave 2 survey when their children were 12 years old. Mothers rated the extent to which they had capacity in terms of time, finance, physical well-being, mental well-being and life in general. Physical punishment, which is linked to more severe childhood maltreatment, was assessed using a question about the use of physical punishment at the wave 3 survey when children were 14 years old. Results After controlling for baseline covariates (including maternal social support, age, marital status, annual household income, educational attainment, child’s age, gender, sibling and birth order, and behavioural difficulties), higher perceived capacity in finance (OR 0.95, 95% CI 0.90 to 0.99, p=0.026) and mental well-being (OR 0.93, 95% CI 0.88 to 0.98, p=0.005) were associated with less frequent use of physical punishment with 14-year-old children. Conclusions Maternal perceived capacity in finance and mental well-being may decrease the risk of frequent use of physical punishment at the 2-year follow-up. Child maltreatment prevention strategies should aim to empower mothers and promote their perceived capacity in financial management and mental health.

    Major depressive disorder (MDD) is associated with repeated exposure to environmental stress. Autophagy is activated under various stress conditions that are associated with several diseases in the brain. This study was aimed at elucidating the autophagy signaling changes in the prefrontal cortex (PFC) under repeated social defeat (RSD) to investigate the involvement of microglial autophagy in RSD-induced behavioral changes. We found that RSD stress, an animal model of MDD, significantly induced initial autophagic signals followed by increased transcription of autophagy-related genes (Atg6, Atg7, and Atg12) in the PFC. Similarly, significantly increased transcripts of ATGs (Atg6, Atg7, Atg12, and Atg5) were confirmed in the postmortem PFC of patients with MDD. The protein levels of the prefrontal cortical LC3B were significantly increased, whereas p62 was significantly decreased in the resilient but not in susceptible mice and patients with MDD. This indicates that enhanced autophagic flux may alleviate stress-induced depression. Furthermore, we identified that FKBP5, an early-stage autophagy regulator, was significantly increased in the PFC of resilient mice at the transcript and protein levels. In addition, the resilient mice exhibited enhanced autophagic flux in the prefrontal cortical microglia, and the autophagic deficiency in microglia aggravated RSD-induced social avoidance, indicating that microglial autophagy involves stress-induced behavioral changes.

    Autistic traits are associated with psychotic experiences in adolescence; however, the mechanisms underlying this relationship are not well understood. Prior research indicates that bullying victimization increases the risk of psychotic experiences in general adolescent populations, and autistic youth are at higher risk of being bullied than their non-autistic peers. Using longitudinal data from general population adolescents aged 10-14 in the Tokyo Teen Cohort study, we tested the hypothesis that bullying is responsible for the association between autistic traits and psychotic experiences in adolescence. We identified an indirect effect (estimate = 0.033 [95% CIs: 0.014-0.057], p < 0.001) between autistic traits and psychotic experiences via bullying victimization, even after controlling for known confounders. Prevention of bullying victimization may be one avenue for reducing risk of psychosis among adolescents with high levels of autistic traits.

    Background Concern has been raised that the COVID-19 pandemic and consequent social distancing measures may increase neuropsychiatric symptoms in people with dementia. Thus, we developed and delivered an e-learning training course to professional caregivers on using a web-based tool for psychosocial interventions for people with dementia. Objective The aim of our study was to evaluate the feasibility and efficacy of an e-learning course in combination with a web-based tool in addressing neuropsychiatric symptoms of dementia. Methods A quasi-experimental design was used in Tokyo, Japan. The e-learning course was delivered three times to professional caregivers between July and December 2020. Caregivers who completed the course assessed the level of neuropsychiatric symptoms in people with dementia using the total score from the Neuropsychiatric Inventory (NPI) via a web-based tool. The primary outcome measures were the number of caregivers who implemented follow-up NPI evaluations by March 2021 and the change in NPI scores from baseline to their most recent follow-up evaluations. As a control group, information was also obtained from professional caregivers who completed a face-to-face training course using the same web-based tool between July 2019 and March 2020. Results A total of 268 caregivers completed the e-learning course in 2020. Of the 268 caregivers, 56 (20.9%) underwent follow-up evaluations with 63 persons with dementia. The average NPI score was significantly reduced from baseline (mean 20.4, SD 16.2) to the most recent follow-up evaluations (mean 14.3, SD 13.4). The effect size was assumed to be medium (Cohen drm [repeated measures]=0.40). The control group consisted of 252 caregivers who completed a face-to-face training course. Of the 252 caregivers, 114 (45.2%) underwent follow-up evaluations. Compared to the control group, caregivers who completed the e-learning course were significantly less likely to implement follow-up evaluations (χ21=52.0, P&lt;.001). The change in NPI scores did not differ according to the type of training course (baseline-adjusted difference=–0.61, P=.69). Conclusions The replacement of face-to-face training with e-learning may have provided professionals with an opportunity to participate in the dementia behavior analysis and support enhancement (DEMBASE) program who may not have participated in the program otherwise. Although the program showed equal efficacy in terms of the two training courses, the feasibility was suboptimal with lower implementation levels for those receiving e-learning training. Thus, further strategies should be developed to improve feasibility by providing motivational triggers for implementation and technical support for care professionals. Using online communities in the program should also be investigated.

    <sec> <title>Background</title> During the second wave of COVID-19 in August 2020, the Tokyo Metropolitan Government implemented public health and social measures to reduce on-site dining. Assessing the associations between human behavior, infection, and social measures is essential to understand achievable reductions in cases and identify the factors driving changes in social dynamics. </sec> <sec> <title>Objective</title> The aim of this study was to investigate the association between nighttime population volumes, the COVID-19 epidemic, and the implementation of public health and social measures in Tokyo. </sec> <sec> <title>Methods</title> We used mobile phone location data to estimate populations between 10 PM and midnight in seven Tokyo metropolitan areas. Mobile phone trajectories were used to distinguish and extract on-site dining from stay-at-work and stay-at-home behaviors. Numbers of new cases and symptom onsets were obtained. Weekly mobility and infection data from March 1 to November 14, 2020, were analyzed using a vector autoregression model. </sec> <sec> <title>Results</title> An increase in the number of symptom onsets was observed 1 week after the nighttime population volume increased (coefficient=0.60, 95% CI 0.28 to 0.92). The effective reproduction number significantly increased 3 weeks after the nighttime population volume increased (coefficient=1.30, 95% CI 0.72 to 1.89). The nighttime population volume increased significantly following reports of decreasing numbers of confirmed cases (coefficient=–0.44, 95% CI –0.73 to –0.15). Implementation of social measures to restaurants and bars was not significantly associated with nighttime population volume (coefficient=0.004, 95% CI –0.07 to 0.08). </sec> <sec> <title>Conclusions</title> The nighttime population started to increase after decreasing incidence of COVID-19 was announced. Considering time lags between infection and behavior changes, social measures should be planned in advance of the surge of an epidemic, sufficiently informed by mobility data. </sec>

    <sec> <title>Background</title> Video game loot boxes, which can typically be purchased by players or are given as reward, contain random virtual items, or loot, ranging from simple customization options for a player's avatar or character, to game-changing equipment such as weapons and armor. Loot boxes have drawn concern, as purchasing loot boxes might lead to the development of problematic gambling for adolescents. Although parental problem gambling is associated with adolescent problem gambling, no studies have evaluated the prevalence of loot box purchases in adolescents’ parents. </sec> <sec> <title>Objective</title> This study investigated the association between loot box purchasing among adolescents and parents, and problem online gaming in population-based samples. </sec> <sec> <title>Methods</title> In total, 1615 adolescent (aged 14 years) gamers from Japan responded to a questionnaire regarding their loot box purchasing and problem online gaming behaviors. Problem online gaming was defined as four or more of the nine addictive behaviors from the Diagnostic and Statistical Manual of Mental Disorders. The adolescents’ primary caregivers were asked about their loot box purchasing. </sec> <sec> <title>Results</title> Of the 1615 participants, 57 (3.5%) reported loot box purchasing. This prevalence did not differ according to primary caregivers’ loot box purchasing, but adolescents who purchased loot boxes were significantly more likely to exhibit problem online gaming (odds ratio 3.75, 95% CI 2.17-6.48). </sec> <sec> <title>Conclusions</title> Adolescent loot box purchasing is linked to problem online gaming, but not with parents’ loot box purchasing. Measures to reduce these behaviors should target reducing addictive symptoms in young video gamers. </sec>

    Background: There are no studies on how the same psychosocial dementia care program is adapted to both in-home and residential care settings. Objective: To evaluate the time investment required by professionals to implement a psychosocial dementia care program to manage neuropsychiatric symptoms. Methods: A prospective observational study design was used. The program consisted of 1) a one-day training course, 2) three interdisciplinary discussion meetings in five months, and 3) a web-based tool for the continued assessment of neuropsychiatric symptoms. Care professionals implemented the intervention in in-home (19 in-home care management agencies and 14 multiple in-home service providers) and residential care settings (19 group homes and eight nursing homes) in Japan from October 2019 to February 2020. The level of neuropsychiatric symptoms for the participants was evaluated using the Neuropsychiatric Inventory (NPI: 0–144). The time investment was reported by participating professionals. A total of 125 persons with dementia were included at baseline. Results: Neuropsychiatric symptoms were significantly decreased at the final follow-up in all types of providers (Cohen’s drm = 0.44–0.61). The mean (SD) time required for the five-month implementation was 417.9 (219.8) minutes. There was a mean (SD) decrease of 8.6 (14.0) points in the total NPI score among the 103 persons with completed interventions. The time investment was significantly lower in in-home care management agencies than in group homes, and lower in follow-ups than at baseline assessment. Conclusion: The program implementation may incur a substantial time investment regardless of setting. An additional benefit scheme to reward the time investment would be helpful to encourage implementation until the follow-ups.

    Abstract Background The Japanese health and welfare industry has a shortage of professional caregivers, and work-related accidents and injuries among this group are therefore especially critical issues. This study aimed to examine the factors associated with turnover intentions and work-related injuries and accidents among professional caregivers in Japan. Methods Self-report questionnaires were distributed to care workers (N= 1396) at 26 geriatric-care facilities. The questionnaire addressed basic attributes, work and organizational characteristics, wage adequacy, and intrinsic motivations for work (e.g., “being suited to caring work”). Social-relational aspects of the work environment were assessed via three subscales of the Social Capital and Ethical Climate in the Workplace instrument (i.e., “Social Capital in the Workplace,” “Exclusive Workplace Climate,” and “Ethical Leadership”). Dependent variables were the experience of work-related accidents or injuries in the prior year and organizational and occupational turnover intentions. We used datasets of professional caregivers for analyses. Results The response rate was 68% (N= 949). Among the 667 professional caregivers, 63% were female. On multivariable logistic regression analysis for work-related accidents and injuries for each sex, those with higher scores for “being suited to caring work” were found to experience significantly fewer work-related accidents and injuries (odds ratio [OR] = 0.78,p&lt; 0.01) among female caregivers. Male caregivers who perceived an exclusive workplace climate experienced more work-related accidents and injuries (OR = 1.61,p&lt; 0.01). However, experience of work-related accidents and injuries did not show significant relationships with organizational and occupational turnover intentions. Additionally, “being suited to caring work” (OR = 0.73,p&lt; 0.01) and ethical leadership (OR = 0.76,p&lt; 0.05) were found to be negatively associated with organizational turnover intentions. “Being suited to caring work” (OR = 0.61,p&lt; 0.01), inadequacy of wage (OR = 2.22,p&lt; 0.05), and marital status (OR = 2.69,p&lt; 0.01) were also associated with occupational turnover intentions of professional caregivers. Conclusions These findings highlight the need to foster intrinsic motivations for work as well as providing a supportive and ethical work environment to reduce high turnover rates and work-related injuries and accidents among professional caregivers.

    AIM: The number of cancer patients with dementia has increased markedly in accordance with aging societies. Cancer patients might receive palliative and end-of-life care to maintain their quality of life; however, the impact of dementia on the quality of death is unexamined in this population. Consequently, we explored the impact of dementia on the quality of death among cancer patients. METHODS: Home palliative care staff members completed questionnaires regarding cancer patients' (n = 508) cognitive status, cancer-related symptoms and quality of death using the good death inventory. Hierarchical regression analyses were carried out for the entire sample and for stratified groups based on the presence of dementia. RESULTS: Of the 508 patients, 156 (30.7%) had dementia. Hierarchical regression analyses revealed that greater quality of death was associated with not having dementia (P < 0.001). Stratified analyses showed that dying at home was related to greater quality of death both in patients with and without dementia. The presence of a primary family caregiver was associated with greater quality of death only in patients with dementia (P < 0.001). CONCLUSIONS: Cancer patients with dementia were less likely to achieve a good death than those without. Our results suggest the importance of enhancing end-of-life care discussions with patients and their families, along with developing specific support strategies to enhance the decision-making of cancer patients with dementia and their family members.

    BACKGROUND: Avoiding inappropriate care transition and enabling people with chronic diseases to die at home have become important health policy issues. Availability of palliative home care services may be related to dying at home. AIM: After controlling for the presence of hospital beds and primary care physicians, we examined the association between availability of home palliative care services and dying at home in conditions requiring such services. DESIGN: Death certificate data in Japan in 2016 were linked with regional healthcare statistics. SETTING/PARTICIPANTS: All adults (18 years or older) who died from conditions needing palliative care in 2016 in Japan were included. RESULTS: There were 922,756 persons included for analysis. Malignant neoplasm (37.4%) accounted for most decedents, followed by heart disease including cerebrovascular disease (31.4%), respiratory disease (14.7%) and dementia/Alzheimer's disease/senility (11.5%). Of decedents, 20.8% died at home or in a nursing home and 79.2% died outside home (hospital/geriatric intermediate care facility). Death at home was more likely in health regions with fewer hospital beds and more primary care physicians, in total and per condition needing palliative care. Number of home palliative care services was negatively associated with death at home. The adjustment for home palliative care services disappeared in heart disease including cerebrovascular disease and reversed in respiratory disease. CONCLUSION: Specialised home palliative care services may be suboptimal, and primary care services may serve as a key access point in providing baseline palliative care to people with conditions needing palliative care. Therefore, primary care services should aim to enhance their palliative care workforce.

    BACKGROUND: As the Japanese population ages, caring for people with Alzheimer's disease (AD) dementia is becoming a major socioeconomic issue. OBJECTIVE: To determine the contribution of patient and caregiver costs to total societal costs associated with AD dementia. METHODS: Baseline data was used from the longitudinal, observational GERAS-J study. Using the Mini-Mental State Examination (MMSE) score, patients routinely visiting memory clinics were stratified into three groups based on AD severity. Health care resource utilizationwas recorded using the Resource Utilization in Dementia questionnaire. Total monthly societal costs were estimated using Japan-specific unit costs of services and products (patient direct health care use, patient social care use, and informal caregiving time). Uncertainty around mean costs was estimated using bootstrapping methods. RESULTS: Overall, 553 community-dwelling patients withADdementia (28.3% mild[MMSE21-26], 37.8% moderate[MMSE 15-20], and 34.0% moderately severe/severe [MMSE < 14]) and their caregivers were enrolled. Patient characteristics were: mean age 80.3 years, 72.7% female, and 13.6% living alone. Caregiver characteristics were: mean age 62.1 years, 70.7% female, 78.8% living with patient, 49.0% child of patient, and 39.2% sole caregiver. Total monthly societal costs of AD dementia (Japanese yen) were: 158,454 (mild), 211,301 (moderate), and 294,224 (moderately severe/severe). Informal caregiving costs comprised over 50% of total costs. CONCLUSION: Baseline results of GERAS-J showed that total monthly societal costs associated with AD dementia increased with AD severity. Caregiver-related costs were the largest cost component. Interventions are needed to decrease informal costs and decrease caregiver burden.

    Background: The Suicide Prevention Act was implemented in 2006 in Japan to promote various suicide prevention strategies. Aims: The present study examined the impact of the Suicide Prevention Act on recent suicide mortality rates in Japan. Method: Using an interrupted time-series design, we analyzed monthly mortality rates between January 1996 and December 2016. Death certificate data from vital statistics were obtained. Results: A total of 597,007 suicides (99.3% of all suicides) were analyzed. At the onset of the economic recession in 1998, a significant increase was observed in overall age-standardized mortality rates and sex-/age-specific populations, except for those aged 60 or older. The difference in trend between before and after implementation of the Suicide Prevention Act was not significant for overall or for any stratified populations. After the onset of the Tōhoku earthquake and tsunami of 2011, mortality rates declined for overall and for sex-/age-specific populations. Limitations: No information was available on what could have led to each suicide. Conclusion: The decline in mortality rates may be due to a significant and recent natural disaster. Further studies are needed to clarify plausible mechanisms for the decline in suicide rates following the Tōhoku disaster.

    PURPOSE: Self-regulation is the capacity to regulate attention, emotion, and behaviour to pursue long-term goals. The current study examined the associations between role model presence and self-regulation during early adolescence, controlling for hopefulness, using a large population-based data set from the Tokyo Teen Cohort study. METHODS: Adolescents, aged 12 years, identified a role model using a single item on a paper questionnaire: 'Who is the person you most look up to?' Level of hopefulness was also assessed using a single question: 'To what extent do you feel hopeful about the future of your life?' Trained investigators evaluated self-regulation. RESULTS: Of 2550 adolescents, 2279 (89.4%) identified a role model. After adjusting for level of hopefulness, identifying a role model was associated with higher levels of self-regulation in comparison to indications of no role model. Hopeful future expectations were also associated with higher self-regulation; however, the beta coefficient was smaller than role model presence in the multivariate linear regression analysis. CONCLUSIONS: Role model presence was significantly associated with higher self-regulation among early adolescents. Educational environments should focus on support for adolescents with no role models.

    BACKGROUND: Anxiety disorders are prevalent among adolescents; however, without objective behavioral markers, anxiety disorders in adolescent populations may often go undiagnosed. Response inhibition is considered as a possible behavioral marker, based on the results with two-gate design, which can aid in early detection of anxiety disorders. The aim of this study was to investigate the relationship between response inhibition and anxiety using a large-scale population-based adolescent sample with single-gate design. METHODS: We used data from the Tokyo Teen Cohort study which was a population-based survey in adolescence. Anxiety was assessed by the Child Behavior Checklist answered by primary caregivers. Response inhibition was measured using the Go/No-Go task. We estimated Pearson's correlation coefficient to test the relationship between response inhibition and anxiety. RESULTS: A total of 2,434 adolescents aged 11-13 years were included in our analyses. We found a significant but weak correlation between response inhibition and adolescent anxiety (r = 0.07, confidence interval 0.03-0.11, p < 0.001). Similar results were shown in most of subgroups according to gender, age, and intelligence. LIMITATIONS: The primary outcome was assessed only via parent-reported questionnaire, leading to potential informant bias. CONCLUSIONS: Response inhibition may not be considered as a suitable behavioral marker of adolescent anxiety.

    Background Autonomy is a key factor in the reduction of inequitable physical healthcare among people with severe mental illness compared with the general population. Aims To clarify the critical mechanism underlying autonomy in physical health promotion based on the perspectives of people with severe mental illness. Method We employed a conventional content analysis of narrative data from the Healthy Active Lives in Japan (HeAL Japan) workshop meetings. Results ‘Inhibited autonomy’ was extracted as a central component and shaped by the users’ experiences, both in a healthcare setting and in real life. This component emerged based on the lack of an empowerment mechanism in psychiatric services. Conclusions A barrier to the encouragement of autonomy in physical health promotion was found in current psychiatric services. An effective strategy should be explored to foster an empowerment mechanism in psychiatric and mental health services. Declaration of interest None.

    OBJECTIVES: Care managers and professional caregivers of home care services are sometimes unaware of the psychosocial approaches to the challenging behaviour of dementia. Therefore, we developed a Behaviour Analytics & Support Enhancement (BASE) programme. We investigated the effects of the programme on the attitudes towards dementia care among professionals. METHOD: Forty-six participants in Japan received training in August 2016. The ongoing monitoring and assessment system was introduced to the participants for repeated measures of challenging behaviour. A 1-day follow-up meeting for debriefing was also performed after two months. A baseline and follow-up questionnaire survey was administered to the participating caregivers using a Japanese version of the Approaches to Dementia Questionnaire (ADQ) and the Zarit Burden Interview (ZBI). RESULTS: A significant improvement was observed in the total ADQ score among the participating caregivers from baseline to follow-up assessment. There was no significant difference between the baseline and follow-up assessment in the ZBI scores. In the follow-up meeting, several participants reported challenges and suggested solutions in facilitating a discussion on an action plan among professionals from various organizations. CONCLUSION: The implementation of the programme resulted in enhanced attitudes towards dementia care among the participants without an increased burden of care. Future studies should examine the programme's effectiveness on the challenging behaviour of persons with dementia.

    OBJECTIVES: The rising prevalence of tobacco use and tobacco-attributable deaths among women is of worldwide concern. In particular, smoking prevention for mothers in early midlife is a significant international public health goal. A higher sense of purpose in life (PIL) is thought to reduce detrimental health behaviours. However, little is known about the association between a sense of PIL and tobacco use. This study investigates this association among community-dwelling mothers of early adolescents. DESIGN: This population-based cross-sectional study uses a self-reported questionnaire from the Tokyo Early Adolescence Survey, a large community-based survey conducted in Japan between 2012 and 2015. SETTING: Participants were randomly recruited from the resident registries of three municipalities in Tokyo, Japan. PARTICIPANTS: A total of 4478 children and their primary parents participated. Responses from 4063 mothers with no missing data were analysed (mean age=42.0 years (SD=4.2)). MEASURES: Participants' tobacco use, including the number of cigarettes smoked per day, was documented using a questionnaire. PIL was assessed using a Purpose in Life scale derived from Ryff's Psychological Well-Being Scale. RESULTS: Greater PIL was associated with a decreased likelihood of tobacco use, even when adjusted for confounders (OR=0.80, 95% CI 0.70 to 0.91). Multinomial logistic regression analyses revealed that PIL was inversely associated with tobacco consumption among mothers. These associations remained after controlling for psychological distress, socioeconomic factors and frequency of alcohol consumption among moderate to heavy smokers (OR=0.70, 95% CI 0.57 to 0.86), while attenuated among light smokers. CONCLUSIONS: Increasing PIL may be a valuable intervention for reducing tobacco use among women in early midlife. This study can contribute to our understanding of the psychology of smoking behaviour and shed light on the targeted intervention to reduce tobacco use among early midlife mothers.

    Little is known about the effectiveness of a psychosocial behaviour management programme on home-dwelling people with dementia. We developed a Behaviour Analytics & Support Enhancement (BASE) programme for care managers and professional caregivers of home care services in Japan. We investigated the effects of BASE on challenging behaviour of home-dwelling people with dementia. METHODS: A cluster-randomized controlled trial was conducted with home care providers from 3 different districts in Tokyo. Each provider recruited persons with dementia aged 65 years or older to receive home care in the BASE programme in August 2016. An online monitoring and assessment system was introduced to the intervention group for repeated measures of challenging behaviour with a total score of the Neuropsychiatric Inventory. Care professionals in both the intervention and control groups evaluated challenging behaviour of persons with dementia at baseline (September 2016) and follow-up (February 2017). RESULTS: A majority of persons with dementia had Alzheimer disease (59.3%). One-hundred and forty-one persons with dementia were included in the intervention group and 142 in the control group. Multilevel modelling revealed a significant reduction in challenging behaviour in the intervention group after 6 months (mean score, 18.3 to 11.2) compared with that of the control group (11.6 to 10.8; P < .05). CONCLUSION: The implementation of the BASE programme resulted in a reduction of challenging behaviour of home-dwelling people with dementia. Future research should examine the long-term effects of behaviour management programmes on behaviour, nursing home placement, and hospital admission of home-dwelling people with dementia.

    BACKGROUND: Suicide rates in Japan are relatively high in OECD countries. A national fund to help local authorities implement suicide prevention programs was launched in 2009. The national suicide prevention project was transferred from the Cabinet Office to the Ministry of Health, Labor, and Welfare on April 2016, with a greater focus on mental health promotion by local governments. AIMS: The aim of the present study was to (a) identify local authorities' implementation of suicide prevention programs in terms of local health policies, and (b) examine the associations between local health resources and suicide rates in Japan. METHOD: We investigated the types of programs implemented under the fund, and correlations with authorities' sociodemographic characteristics and mental health and welfare resources. RESULTS: A majority of authorities implemented general suicide prevention programs. More focused programs addressing issues such as mental health in the workplace, alcohol problems, and attempted suicide were less frequently implemented. There were significantly fewer suicides in health regions with a higher ratio of psychiatrists to residents or a lower ratio of psychiatric beds. LIMITATIONS: A causal relationship between suicide rates and characteristics of local authorities cannot be inferred from the data. CONCLUSION: A community mental health system that operated in parallel to the current system may result in fewer inpatients and a reduction in Japan's suicide rate.

    OBJECTIVES: Women have higher rates of auditory verbal hallucinations (AVH) than men; however, less is known about sex differences in the prevalence of AVH in early, middle and late adolescence. We sought to elucidate the differences in the prevalence of AVH and to examine the degree to which these differences could be explained by differences in levels of depressive symptoms. DESIGN: We used a cross-sectional design and a self-reported questionnaire. SETTING: Participants were recruited from public junior and senior high schools in Tsu, Mie Prefecture and Kochi Prefecture, Japan. PARTICIPANTS: In total, 19 436 students were contacted and 18 250 participated. Responses from 17 451 students with no missing data were analysed (aged 12-18 years, Mage=15.2 years (SD=1.7), 50.6% girls). MEASURES: AVH were assessed through one of four items adopted from the schizophrenia section of the Japanese version of the Diagnostic Interview Schedule for Children. Depressive symptoms were assessed using the 12-item General Health Questionnaire. RESULTS: The prevalence of AVH was 7.0% among early adolescents (aged 12-13 years), 6.2% among middle adolescents (aged 14-15 years) and 4.8% among late adolescents (aged 16-18 years). Being female was significantly associated with a higher prevalence of AVH through adolescence (OR=1.71, 95% CI 1.31 to 2.23 in early adolescence; OR=1.42, 95% CI 1.14 to 1.76 in middle adolescence; OR=1.52, 95% CI 1.23 to 1.87 in late adolescence); however, these differences became non-significant after adjusting for depressive symptoms (OR=1.21, 95% CI 0.92 to 1.60; OR=1.00, 95% CI 0.80 to 1.25; OR=1.16, 95% CI 0.93 to 1.44, respectively). CONCLUSIONS: Sex differences in auditory hallucinations are seen in both adult and youth populations. The higher rates of auditory verbal hallucinations seen in girls may be secondary to the differences in the rate of depressive symptoms.

    A suicide prevention strategy was launched in Japan in 2006 to address the high suicide rate, which had increased considerably since 1998. The national strategy from 2007 involved the enhancement of psychiatric treatment services at emergency medical facilities and supportive observation by individuals close to patients. The national suicide rate has decreased gradually since 2008; however, national information regarding the number of patients who had engaged in deliberate self-harm was absent. Therefore, the present study examined the longitudinal trend in hospital admissions due to deliberate self-harm in Japan. Data from the National Patient Survey between 1996 and 2014-a nationally representative cross-sectional survey of inpatient care every 3 years-were used. Data for 13,014 patients were included in the estimation of the number of hospital admissions due to deliberate self-harm. The results show that the estimated number of admissions due to deliberate self-harm increased from 2078 in September 1996 to 3189 in September 2008, when the national number of suicide cases peaked, and decreased to 1783 in 2014. Approximately half of the patients were admitted to hospital because of self-harm via means other than drug poisoning, which had a high mortality rate (5.6%). The proportion of patients receiving public assistance was higher in those who had engaged in deliberate self-harm (8.5%) relative to that observed in the general population. Overall, the trend in deliberate self-harm was synchronous with the number of suicide cases over time. As economic poverty has been associated with suicidal ideation and behavior and some recipients of public assistance tend to abuse psychotropic medication, the public assistance program should provide mental health support for recipients of social benefit schemes.

    OBJECTIVES: Japanese special nursing homes provide permanent residence to elderly people under the public long-term care insurance program. However, a quarter of discharges occur via death in hospital, and a fifth occur via admission to hospital. The objective was to identify factors associated with discharge destinations for residents of Japanese special nursing homes. DESIGN: A retrospective design for data collected in 2007, 2010, and 2013. SETTING: We used data from the Survey of Institutions and Establishments for Long-Term Care, which is a nationally representative cross-sectional survey that assessed discharge from special nursing homes in September every 3 years. PARTICIPANTS: There were 2426 discharged residents included in the analysis. MEASUREMENTS: Discharge destination was categorized as death at facility, death in hospital, hospital admission, and another care setting. Multivariate multinomial logistic regression analysis was conducted with discharge destination as the dependent variable. RESULTS: Of the 2426 discharged residents included in the analysis, 874 (36.0%) were deceased at the facility, 773 (31.9%) were deceased in hospital, 652 (26.9%) were admitted to hospital, and 127 (5.2%) were admitted to another care setting. Residents of facilities in the regions with fewer nursing home beds or more hospital beds were more likely to be discharged via admittance to hospital or another care setting relative to being deceased at the facility. CONCLUSION: The regional supply of nursing home and hospital beds could have affected end-of-life care locations for residents of special nursing homes. To promote end-of-life care in special nursing homes, regional supply of nursing home beds should be reinforced while controlling oversupply of hospital beds.

    Objectives Group living is an approach that can create small, homelike environments in traditional nursing homes in Japan. The aim of the present study was to examine quality of life (QOL) of residents with dementia in group-living situations.<br/>Methods The group-living group consisted of facilities that formed residential units. Each unit had a common area and stable staff assignments. The control group consisted of facilities that did not form residential units. The quality of life instrument for Japanese elderly with dementia (QLDJ) scale was used to rate QOL by direct care workers of 616 residents with dementia from 173 facilities in the group-living group and 750 residents from 174 facilities in the control group. QOL was based on the following subscales: interacting with surroundings; expressing oneself; and experiencing minimal negative behavior.<br/>Results Multilevel regression analyses demonstrated a significantly greater QOL with respect to interacting with surroundings, expressing oneself, and experiencing minimal negative behavior for residents with dementia in the group-living group compared to the control group, as measured by the QLDJ. The total QLDJ score was also significantly higher for the group-living group.<br/>Conclusion The results suggest improved QOL of residents with dementia under group-living situations. Future studies should examine the effect of group-living on QOL of residents with dementia using a cohort design, following residents longitudinally from admission.

    Objectives&emsp;The present study was conducted to assess current implementation of discharge planning in the care of hospitalized older adults, and to examine the association between implementation and involvement of home care providers at hospitals.<br/>Methods&emsp;The subjects were 434 hospitals with 100 beds or more for general patients, nationwide. We conducted a questionnaire survey by mail of hospital staff responsible for the discharge planning, and assessed to what extent home care providers were associated with the implementation of discharge planning in the hospitals. The subjects were divided into two groups: an association group (138 hospitals) in which home care providers were associated with implementation in the hospitals, and a not-association group (296 hospitals). We compared the proportions of implementation of discharge planning between the two groups, and calculated odds-ratios. In the analysis, we controlled for affiliated institution and home care services.<br/>Results&emsp;The association group showed significantly higher proportions of implementation for 13 items in a total 24 items for discharge planning than the not-association group (range of odds-ratio: 2.430-5.497). The three highest odds ratios were observed for &ldquo;Arrangement and guidance for home care by outreach prior to discharge&rdquo; [OR=5.497, 95% confidence interval (CI): 2.604-11.602], &ldquo;Adjusting relationship between patient and family&rdquo; (OR=4.871, 95%CI: 1.323-17.930) and &ldquo;Refining medical and nursing care so as to be sustainable at home&rdquo; (OR=4.740, 95%CI: 1.825-12.311).<br/>Conclusions&emsp;The present study showed that hospitals with involvement of home care providers had higher proportions of implementation of discharge planning for hospitalized older adults concerning &ldquo;Arrangement and guidance for home care by outreach prior to discharge&rdquo;, &ldquo;Adjusting relationship between patient and family&rdquo;, &ldquo;Refining medical and nursing care so as to be sustainable at home&rdquo; and so on. Further study should examine the effect of discharge planning on length of stay, rate of readmission, patient and family member's satisfaction controlling for patient characteristics and hospital's role in the community.

    本研究は, 保護者用包括的ニーズ評価尺度CAN-SCS (P-version) を用いて, スクールカウンセラーの活動内容に対する保護者の要望の変化を明らかにすることを目的として行われた。2000年度4月よりスクールカウンセラーが配置された都内の私立女子中高等学校B校の協力により, 同校の保護者を対象として2000年度 (スクールカウンセラーの導入直後) と2001年度 (1年後) の2時点で無記名式の質問紙調査を行った。回収率は2000年度が66.2%(789/1192), 2001年度が47.7%(563/1178) であった。2001年度の回答者のうち, 「2000年度も調査に回答しましたか」という項目で「はい」と回答し, かつ2000年度のデータと照合して同定できた213人を本研究の分析対象とした。調査の結果, 1年間のスクールカウンセリング活動に対する保護者の評価は「分からない」という回答が多く, もっとも評価の得点が高かったのは「カウンセラー室の知られている程度」であった。この1年間はスクールカウンセラーの存在が保護者に認識されるようになるまでの期間であったと考えられた。2000年度と比べて2001年度の保護者の要望が高くなった活動内容は, 生徒集団への援助や地域との連携など, 2000年度の段階では要望が低かったものである傾向がみられた。このことから, 1年間のスクールカウンセリング活動を通してスクールカウンセラーの役割像が広がったことが示唆された。全体的にスクールカウンセラーに対する要望が高くなった保護者は, スクールカウンセラーに対する関心が高かった者であった。

    日本において, スクールカウンセラーに対する保護者のニーズを社会科学的に調査した研究はほとんどない。本研究は保護者用包括的ニーズ評価尺度CAN-SCS (P-version) を用いて, スクールカウンセラーの活動内容に対する保護者のニーズを明らかにする目的で行われた。都内の私立女子中高等学校A校とB校の2校から調査の同意が得られ, 同校の保護者を対象として質問紙調査を行った。どちらの学校も2000年度4月よりスクールカウンセラーが配置された。回答率はA校が67.9%(679/1000), B校が66.2%(789/1192) であった。質問紙の中でスクールカウンセラーの活動内容33項目を (1) 生徒に対する援助, (2) 教職員に対する援助, (3) 保護者に対する援助, および (4) 地域や外部機関との関わりに分けて示し, 保護者はそれぞれの活動内容について必要性の程度を評価した。本研究の結果, スクールカウンセラーの活動内容の多くが保護者に必要とされていた。保護者が求める活動内容は個別相談に留まらず, 教職員集団に対する援助や外部機関との連絡・連携といった活動に対しても一定のニーズが示された。スクールカウンセラーに多くの活動内容を求める保護者は, スクールカウンセラーに対する関心が高かった。スクールカウンセラーが保護者のニーズに対応した活動を行い保護者の関心を広げることで, 活動内容に対する保護者のニーズが広がることが示唆された。将来の研究の方向性として, 対象を広げ検討すること, スクールカウンセラーの活動を経た保護者のニーズの変化を明らかにすることが望まれる。

    <p>Based on the "Healthy Work Organization (HWO)" conceptual model, we conducted a qualitative study using a semi-structured interview subjecting 14 unit-leaders of professional caregivers in elderly care facilities to reveal the actual condition of factors involved in their turnover. Three categories, that consist of 23 sub-categories identified from 62 codes, emerged regarding factors of resignation among professional care givers. One of the categories, namely "specificity of care services," was fit to the "work and workplace characteristics" within the HWO conceptual model, and the remaining two categories, namely "not established labor and personnel management system" and "undeveloped organizational policy and structure," were fit to the "organizational characteristics" in the model. The findings suggested that countermeasures toward the turnover of professional caregivers are required for both the work and the workplace characteristics and the organizational characteristics influencing the former characteristics.</p>

    The aim of this study was to determine what the Good Death is in people with dementia and whether it is being achieved. As a result of the literature review, interview and questionnaire surveys, the components of Good Death in patients with dementia were categorized into four factors: “comfort, security and safety,” “relationships,” “independence,” and “the ability to maintain their individuality and lack of constraint.” A survey of bereaved families found that, overall, Good Death was more frequently achieved in people with dementia.

    We conducted qualitative and quantitative research using Healthy Work Organization model to examine the influence of Organizational Characteristics (OC) as factors involved in Organizational Health (e.g., intentions to leave) in facilities in regional comprehensive healthcare system. For quantitative research, nurses and professional care workers（N = 1396) of 26 facilities were invited to participate (response rate was 68%). We addressed original 20-item scale of the social capital and ethical climate at the workplace (SEW) as OC. The findings revealed that organizational characteristics influenced on Organizational Health (e.g., work-related accidents and injuries, their intentions to leave, happiness at workplace). Additionally, the findings of qualitative research revealed three categories for factors of turnover and two categories for factors of retention, respectively. Findings suggested the countermeasures for OC.

    More details Close

    In this study, we aimed to formulate guidelines for severe psychiatric outpatients who live in their community and with their families. We created a draft of the guideline by examining the contents of pre-existing guidelines and evaluation methods. We selected eight areas, 20 categories, and 97 items to evaluate for "The Care" content. The delphi method was used to evaluate the guidelines. The assessment was conducted as an anonymous survey on a web, measuring the importance, difficulty, and frequency of the care. 50 professionals participated in our study. The primary results revealed that 96 items out of 97 of the importance section scored 8.0 points or over, with interquartile range (IQR) percentage (percentage of respondents who fall within IQR range) of 76.0 ～ 92.0%. The importance of the formulated care items were generally highly valued. There were minimal scatters of the answers. Further assessment is necessary to increase the validity of the study.

    We formed a core research team consisting of mental health professionals and users.On this team, we continuously discussed what kind of structure and care factors were necessary to implement Shared Decision Making (SDM) with users in the psychiatric emergency unit. Through these discussions and inspections of overseas service providers that implemented patient-centered care and review of literature, we revealed that Trauma Informed Care (TIC), which was implemented mainly in the USA since the 1990s was effective. We conducted training for psychiatric clinical staff and investigated changes in knowledge and attitudes of participants both pre and post the training using self-reported questionnaires.

    More details Close

    Restrictions in patients' freedom of movement, such as physical restraint and seclusion, have negative impacts on patients and healthcare providers. Our goal is to create an environment in which service providers are aware of their own feelings and have dialogues with patients/users. This type of environment would develop the service setting into a place where restraints are not required. Therefore, we developed a dialogue-oriented training workshop that is based on peer support relationships by reference to Intentional Peer Support. The workshop participants reported that they noticed the importance of being aware of their feelings. We were unable to reach the phase of examining the effect on decreasing physical restraint and seclusion.

    This research is based on the focus group interviews by occupation targeting certified social workers, public health nurses, chief care managers, and administrative officers of the community general support centers in two areas. The survey found that there exist two types of action assignments: those different from each other depending on the areas and community general support centers and those in common with each other. This research makes proposals (draft)for promoting a system to provide appropriate countermeasures against elderly abuse while classifying these common action assignments into the following five categories; the internal organization of administration, the internal organization of a community general support center,organization for cooperation and coordination between administration and a community general support center, regional organization surrounding the community general support center, and the national-level policies.
