Comparison of the 12-item and 36-item versions of the World Health Organization Disability Assessment Schedule (WHODAS) 2.0 using longitudinal data from community mental health outreach service users

AIM

This study aimed to compare the 12-item and 36-item versions of the World Health Organization Disability Assessment Schedule (WHODAS) 2.0 using longitudinal data from community mental health outreach service users.

METHODS

Using data from Tokorozawa City mental health outreach service users in Japan, total and domain WHODAS-12 and WHODAS-36 scores were compared. First, we examined score-change differences by domain at the start of outreach services (T1) and 1 year later (T2) for each version. Next, we compared differences between the two versions using Pearson's correlation, Wilcoxon signed-rank test, and Bland-Altman analysis.

RESULTS

Among 20 participants, total scores and scores of some domains (i.e., cognition, getting along, life activities, and participation) were significantly lower at T2 than at T1 on both versions (p < 0.010). WHODAS-36 scores were significantly lower at T2 than at T1 for the self-care domain (p = 0.018). Except for self-care, strong correlations were found between scores from the two versions (p < 0.001). In the Wilcoxon signed-rank test and Bland-Altman analysis, we found significant differences between the scores of the two versions in the mobility, self-care, and participation domains. There were no significant differences in the distribution or systematic errors between the two versions in scores for the other domains or total score.

CONCLUSION

We found strong positive correlations between WHODAS-12 and WHODAS-36 total scores with no statistical differences between them. For some domains, differences in distribution and systematic errors were found.

Data resource profile of an online database system for forensic mental health services

This paper introduces a forensic psychiatry database established in Japan and discusses its significance and future issues. The purpose of this Database, created under the Medical Treatment and Supervision Act (MTSA) Database Project, is to improve the quality of forensic psychiatry treatment. It can collect monthly data on "basic information," "Orders and hospitalizations under the MTSA," "Treatment process," "Criminal and medical treatment history," and "problematic behavior in the unit." The online system has accumulated data on more than 8,000 items in 24 broad categories. Medical data are exported from the medical care assisting system of 32 designated inpatient facilities in XML format and then saved on USB memory sticks. The files are imported into the Database system client, which sends the data to the Database server via a virtual private network. This system minimizes errors and efficiently imports patient data. However, there is a limitation that it is difficult to set items that need to be analyzed to solve everyday clinical problems into the database system because they tend to change over time. By evaluating the effectiveness of the Database, and collecting appropriate data, it is expected to disseminate a wide range of knowledge that will contribute to the future development of mental health and welfare care.

Ranking important predictors of the need for a high-acuity psychiatry unit among 2,064 inpatients admitted to psychiatric emergency hospitals: a random forest model

Aims

In order to uphold and enhance the emergency psychiatric care system, a thorough comprehension of the characteristics of patients who require a high-acuity psychiatry unit is indispensable. We aimed to clarify the most important predictors of the need for a high-acuity psychiatry unit using a random forest model.

Methods

This cross-sectional study encompassed patients admitted to psychiatric emergency hospitals at 161 medical institutions across Japan between December 8, 2022, and January 31, 2023. Questionnaires were completed by psychiatrists, with a maximum of 30 patients assessed per medical institution. The questionnaires included psychiatrists' assessment of the patient's condition (exposure variables) and the need for a high-acuity psychiatry unit (outcome variables). The exposure variables consisted of 32 binary variables, including age, diagnoses, and clinical condition (i.e., factors on the clinical profile, emergency treatment requirements, and purpose of hospitalization). The outcome variable was the need for a high-acuity psychiatry unit, scored from 0 to 10. To identify the most important predictors of the need for a high-acuity psychiatry unit, we used a random forest model. As a sensitivity analysis, multivariate linear regression analysis was performed.

Results

Data on 2,164 patients from 81 medical institutions were obtained (response rate, 50.3%). After excluding participants with missing values, this analysis included 2,064 patients. Of the 32 items, the top-5 predictors of the need for a high-acuity psychiatry unit were the essentiality of inpatient treatment (otherwise, symptoms will worsen or linger), need for 24-hour professional care, symptom severity, safety ensured by specialized equipment, and medication management. These items were each significantly and positively associated with the need for a high-acuity psychiatry unit in linear regression analyses (p < 0.001 for all). Conversely, items on age and diagnosis were lower in the ranking and were not statistically significant in linear regression models.

Conclusion

Items related to the patient's clinical profile might hold greater importance in predicting the need for a high-acuity psychiatry unit than do items associated with age and diagnosis.

Perceptions and attitudes of users and non-users of mental health services concerning mental illness and services in Japan

Objectives

There is a global movement to develop and implement community-based integrated mental health systems. The present study attempted to clarify the perceptions and attitudes of users and non-users of mental health services concerning mental illness and services in Japan.

Methods

A new questionnaire was developed for this internet survey. Data from 500 outpatients with depression and 500 healthy subjects were sampled according to the demographics of the Japanese population.

Results

Over 90% of healthy subjects and over 70% of patients were unaware of the common age of onset or lifetime prevalence of mental illness. Over 90% of the healthy subjects and about 70% of the patients could not describe any services where they would feel comfortable discussing mental health problems. In both groups, "adolescents and young adults" were ranked first as a target population for mental health and illness policies. The top requirement for the integrated care systems was the promotion and awareness of correct knowledge of mental illness in both the healthy subjects and patients.

Conclusion

Societal requirements could include disseminating correct knowledge, awareness-raising actions for society, and implementing services where people, especially young people, can easily consult and receive support in the community.

Mental health help-seeking preferences and behaviour in elite male rugby players

Objectives

Mental health symptoms and mental illnesses are common in elite athletes. There is an urgent need to develop care systems to support the mental health of elite athletes. Understanding elite athletes' preferences in mental health help seeking can help explore strategies to develop such systems. Therefore, this study aims to investigate with whom/where elite athletes feel comfortable discussing mental health concerns and seeking help.

Methods

We analyse data from 219 Japanese male rugby players out of 612 players (565 Japanese, 47 foreigners) aged 18 and over who belong to the Japan Rugby Players Association using a cross-sectional design and an anonymous, web-based, self-administered questionnaire. In the questionnaire, the players are asked to rate on a 5-point Likert scale how comfortable they feel talking about their mental health concerns with affiliation/team staff, family/relatives, friends, mental health professionals, rugby-related seniors and teammates. Analysis of variance and Dunnett's test are performed to detect differences in their preferences for sources of help.

Results

Dunnett's test shows that the mean scores for preferring to consult affiliation/team staff are significantly lower than for all the other groups (p<0.001), indicating that players are reluctant to seek help for mental health concerns from affiliation/team staff. Fewer players sought help from affiliation/team staff or mental health professionals than from other groups.

Conclusion

Regarding mental health concerns, for elite male rugby players as elite athletes, it can be difficult to ask for help or talk to team staff.

What outcomes in community mental health research are important to caregivers of people with schizophrenia? An exploratory qualitative analysis of an online survey

AIMS

This study investigated outcomes in community mental health research that were important to caregivers of people with schizophrenia.

METHODS

Using an online survey conducted from August 1 to 31, 2020, data were collected from caregivers belonging to the LINE Schizophrenia Family Association. Caregivers identified outcomes important in community mental health research. Two researchers categorized caregivers' statements into research outcomes.

RESULTS

A total of 132 caregivers completed the online selfreported questionnaire, and 296 caregiver statements were identified. Qualitative analysis identified 17 outcome categories. The caregivers tended to value having more free time, maintaining an appropriate relationship with people with schizophrenia, and being able to cope with their symptoms.

CONCLUSIONS

This exploratory study newly demonstrates the outcomes that caregivers of people with schizophrenia consider important in community mental health research. The findings may be useful in selecting outcomes for future studies of caregivers.

Influence of multi-aspect job preference matching on job tenure for people with mental disorders in supported employment programs in Japan

OBJECTIVE

This study examined the association between job tenure and job preference matching for five job preference domains for people with mental disorders enrolled in Individual Placement and Support (IPS) programs in Japan. The domains include occupation type, monthly income, weekly work hours, commute time, and illness disclosure.

METHODS

We conducted secondary analysis of participants who obtained employment in a longitudinal study during the 24-month follow-up period at 16 agencies routinely providing IPS programs. We included 112 participants who expressed job preferences and were employed at least once. A total of 130 employment cases were analyzed. Matches in the five domains were determined using participants' job preferences and employment information. The Match Level (0-5) indicates the number of domains that match the participant's job preferences. Job tenure (weeks worked) was compared between the matched and unmatched groups in each domain and between each match levels using linear regression mixed-effects models.

RESULTS

A match for a given domain did not show a significant relationship with job tenure, whereas Match Levels 3 (B = 29.6, 95% CI [10.8, 48.4], p = .003) and 4 (B = 37.0, 95% CI [17.1, 56.9], p < .001) had a significantly longer tenure than those with Match Level 1.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

A higher match level may be related to a longer job tenure. The results suggest that employment specialists should prioritize clients' preferences in job searches. Further replication studies in other settings and countries should be conducted to verify the findings in this study. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Multiple stakeholders' perspectives on patient and public involvement in community mental health services research: A qualitative analysis

Background

Patient and public involvement (PPI) has become essential in health research. However, little is known about multiple stakeholders' perspectives on the implementation of PPI in community mental health research settings. The present study aimed to qualitatively analyse multiple stakeholders' views on PPI, including potential concerns, barriers and approaches.

Methods

This study involved conducting focus group interviews and collecting qualitative data from 37 participants in multiple stakeholder groups (patients = 6, caregivers = 5, service providers = 7, government staff = 5 and researchers = 14) in the community mental health field. The data were qualitatively analysed using a data‐driven approach that derived domains, themes and subthemes related to perspectives on PPI and to specific challenges and approaches for implementing PPI.

Results

The qualitative analysis identified four domains. The ‘Positive views and expectations regarding PPI’ domain consisted of themes related to supportive views of PPI in a mental health service research setting and improvements in the quality of research and service. The ‘General concerns about PPI’ domain included themes concerning the need for non‐PPI research and tokenism, excessive expectations concerning social changes and use of evidence from PPI research, and heavy burdens resulting from PPI. The ‘Specific issues regarding the implementation of PPI’ domain consisted of four themes, including academic systems, selection methods (e.g., representativeness and conflict of interest issues), relationship building, and ambiguous PPI criteria. In particular, all stakeholder groups expressed concerns about relational equality during PPI implementation in Japan. The ‘Approaches to PPI implementation’ domain included themes such as facilitating mutual understanding, creating a tolerant atmosphere, establishing PPI support systems (e.g., training, ethics and human resource matching) and empowering patient organizations.

Conclusion

The study replicated most of the barriers and approaches to PPI reported by qualitative research in Western counties. However, utilization of evidence produced by PPI research and partnership in the PPI process may be particularly serious issues in Japan. Future PPI studies should carefully address solutions that fit each culture.

Anxiety and Depressive Symptoms in the New Life With COVID-19: A Comparative Cross-Sectional Study in Japan Rugby Top League Players

Objectives: The primary objective is to compare the prevalence of mental health problems, including psychological distress, anxiety and depressive symptoms in Japan Rugby Top League players in the new life with COVID-19 with those evaluated before COVID-19.

Methods: An observational comparative web-based cross-sectional study was employed for Japan Rugby Top League players. We compared the data from 220 Japanese and 7 foreign players during the new life with COVID-19 with the data from before COVID-19, which was obtained from 233 Japanese and 18 foreign players. We measured anxiety and depression symptoms with the validated Kessler-6, which has been widely used in clinical and research settings among different populations. To investigate the distribution of K6 score and whether there are discrete clusters or not, we conducted the two-step cluster analysis.

Results: In the new life with COVID-19, 15.0% of players reported mild symptoms, which was significantly lower than the 32.3% of players before COVID-19. The prevalence of moderate and severe symptoms was 6.7 and 3.5%, respectively, in the group during the new life with the COVID-19, and 4.8 and 5.2% in the pre-COVID-19 group, with no significant difference. A two-step cluster analysis supported the existence of these two qualitatively different clusters in both groups.

Conclusions: With the spread of new lifestyles related to COVID-19, some rugby players may have improved mental health status due to changes in their daily living environment. Such environmental adjustments alone may not have been sufficient to change the mental health status of others. Rugby players or their teams may require mental health professionals and systems that ensure rest, adjust the environment, and sustainably provide more professional care.

Validating a Japanese Version of the Athlete Psychological Strain Questionnaire

Background

There is increasing international interest in clinical practice and research related to mental health in the international sports society. The athlete-specific psychological distress assessment tool that addresses potential mental health needs can help promote early detection and recovery of mental illness, as well as physical illnesses. Currently, little is known about the applicability of the useful assessment tool for Japanese elite athletes. The Athlete Psychological Strain Questionnaire (APSQ) is a brief, effective and reliable screening tool to identify early signs of athlete-specific distress and potential mental health symptoms. We examined the applicability and reliability of a Japanese version of the APSQ (APSQ-J) in a Japanese elite athlete context. Further, we examined the construct validity of the APSQ-J.

Methods

We collected web-based anonymous self-report data from 219 currently competing Japanese professional male rugby players. A two-stage process was conducted to validate the factor structure of the APSQ-J using exploratory factor analysis (EFA) in a randomly partitioned calibration sample and confirmatory factor analysis (CFA) in a separate validation sample. Cronbach’s alpha is used to assess internal consistency. Pearson product-moment correlation coefficients were calculated to determine if the APSQ-J was significantly associated with measures of psychological distress and well-being using Kessler-6 (K6) and the WHO-5 Well-Being Index, respectively.

Results

We identified a one-factor structure for the APSQ-J. Confirmatory factor analysis supports this one-factor model, revealing good model fit indices. The standardized path coefficients for each of the items were β = 0.41–0.83 (p < 0.001). A Cronbach’s alpha of 0.84 was obtained for the APSQ-J. The APSQ-J demonstrated significant correlations with the K-6 (r = 0.80, p < 0.001) and WHO-5 (r = −0.58, p < 0.001).

Conclusion

The APSQ-J can be an appropriate and psychometrically robust measure for identifying athlete-specific distress in elite athletes in Japan. Widely disseminating and utilizing this scale in Japanese sports society may support athletes' mental health via early detection of symptoms of psychological distress.

Outcomes frequently specified in Cochrane reviews of community-based psychosocial interventions for adults with severe mental illness: A systematic search and narrative synthesis

Background

Outcome selection in intervention studies is a critical issue for synthesizing evidence. This study is aimed to investigate outcomes used in Cochrane reviews assessing community‐based psychosocial interventions for adults with severe mental illness.

Methods

Cochrane reviews that evaluated a community‐based psychosocial intervention for adults with severe mental illness were searched electronically and manually. We extracted all outcomes specified in the Methods section in each Cochrane review. Outcomes that represent the same concept and context were synthesized into an outcome term. Outcome terms were categorized according to the existing taxonomy.

Results

We included 33 Cochrane reviews. Of the 216 outcome terms identified, 13 were used in more than half of the reviews: quality of life, mental state, admission to hospital, economic outcome, leaving the study early, social functioning, satisfaction, global state, relapse, adverse events/effects, carer satisfaction, employment, and duration of admission. Most outcome terms were categorized into the life impact core area (55%), followed by the resource use area (21%).

Conclusions

Our study provides a candidate outcome list for developing a core outcome set for severe mental illness and offers a basis for comparison for future outcome investigation on mental health research.

Two hundred and sixteen outcome terms were found by investigating all the outcomes used in 33 Cochrane reviews assessing community‐based psychosocial interventions for adults with severe mental illness. Thirteen outcome terms were used in more than half of the reviews: quality of life, mental state, admission to hospital, economic outcome, leaving the study early, social functioning, satisfaction, global state, relapse, adverse events/effects, carer satisfaction, employment, and duration of admission.

Consensus development of priority outcome domains for community mental health cares by multiple stakeholders: Protocol for an online Delphi study in Japan

Background

Treatment goals for mental illness have expanded from hospital discharge and improved functioning to employment, living alone, and personal realization. These changes in treatment goals have also influenced mental health research. Recent studies have addressed the development of core outcome sets focusing on clinical aspects of mental illness such as depression and anxiety. However, a well‐developed framework of essential outcomes for people with mental illness (service users) who live in the community is lacking. In addition, recent worldwide trends suggest more patient and public involvement and the importance of considering multiple stakeholders’ views in the area of mental health research. Purpose of this study is to explore consensus on high‐priority outcome domains among multiple stakeholders in community mental healthcare fields in Japan.

Methods

A three‐step approach to developing an outcome list will be used. First, we developed a long list of outcomes for community mental health through a literature review, focus group interviews with key stakeholders, and online questionnaire surveys of service users and caregivers. Second, the long list was checked and revised in a pilot study. Third, the long list will be shortened to the outcome list through the Delphi methodology with participation from multiple stakeholders.

Discussion

Identifying important common outcome domains through collaboration with multiple stakeholders appears to contribute to the development of evidence for community mental health research in Japan. In addition, the study process itself may help promote patient and public involvement in education, practice, and research in the field of community mental health.

Predictive Association of Low- and High-Fidelity Supported Employment Programs with Multiple Outcomes in a Real-World Setting: A Prospective Longitudinal Multi-site Study

PURPOSE

The individual placement and support (IPS) model of supported employment is a leading evidence-based practice in community mental health services. In Japan, individualized supported employment that is highly informed by the philosophy of the IPS model has been implemented. While there is a body of evidence demonstrating the association between program fidelity and the proportion of participants gaining competitive employment, the association between fidelity and a wider set of vocational and individual outcomes has received limited investigation. This study aimed to assess whether high-fidelity individualized supported employment programs were superior to low-fidelity programs in terms of vocational outcomes, preferred job acquisition, and patient-reported outcome measures (PROMs).

METHODS

A prospective longitudinal study with 24-month follow-up analyzed 16 individualized supported employment programs. The Japanese version of the individualized Supported Employment Fidelity scale (JiSEF) was used to assess the structural quality of supported employment programs (scores: low-fidelity program, ≤ 90; high-fidelity program, ≥ 91). Job acquisition, work tenure, work earnings, job preference matching (e.g., occupation type, salary, and illness disclosure), and PROMs such as the INSPIRE and WHO-Five Well-being index were compared between groups.

RESULTS

There were 75 and 127 participants in the low-fidelity group (k = 6) and high-fidelity group (k = 10), respectively. The high-fidelity group demonstrated better vocational outcomes than the low-fidelity group, i.e., higher competitive job acquisition (71.7% versus 38.7%, respectively, adjusted odds ratio (aOR) = 3.6, p = 0.002), longer work tenure (adjusted mean difference = 140.8, p < 0.001), and better match for illness disclosure preference (92.6% versus 68.0%, respectively, aOR = 5.9, p = 0.003). However, we found no differences between groups in other preference matches or PROM outcomes.

CONCLUSION

High-fidelity individualized supported employment programs resulted in good vocational outcomes in a real-world setting. However, enhancing service quality to increase desired job acquisition and improve PROMs will be important in the future.

Association of mental health help-seeking with mental health-related knowledge and stigma in Japan Rugby Top League players

Background

Globally increasing clinical and research interests are driving a movement to promote understanding and practice of mental health in elite athletes. However, few studies have yet addressed this issue. This study aims to describe the association of the intention to seek help with mental health knowledge and stigma and the severity of depressive symptoms in Japan Rugby Top League players.

Methods

As a target population, we studied 233 Japan Rugby Top League male players (25–29 years = 123 [52.8%]), who were born in Japan, using a cross-sectional design. Surveys were conducted using anonymous, web-based self-administered questionnaires. Structural equation modelling was performed to evaluate the hypothesis of an interrelationship between mental health knowledge, stigma, and severity of depressive symptoms as factors influencing the intention to seek help.

Results

Players with more severe depressive symptoms were more reluctant to seek help from others (β = - 0.20, p = 0.03). Players with greater knowledge about mental health tended to have less stigma toward others with mental health problems (β = 0.13, p = 0.049), but tended not to seek help with their own mental health problems.

Conclusions

Rugby players in need of mental health support, even with greater knowledge, tend not to seek help from others, while having less stigma toward people with mental health problems. Rugby players might require approaches other than a knowledge-based educational approach to encourage them to seek help.

Care difficulties and burden during COVID-19 pandemic lockdowns among caregivers of people with schizophrenia: A cross-sectional study

Aims

The purpose of this study was to retrospectively investigate care difficulties experienced by caregivers of people with schizophrenia during COVID‐19 pandemic lockdowns in Japan (April 7‐May 25, 2020) and examine associations between these care difficulties during lockdowns and daily caregiver burden.

Methods

Data were collected from 132 participants of the LINE Schizophrenia Family Association using an online survey.

Results

Caregivers were mostly concerned about who would care for people with schizophrenia if caregivers become infected with COVID‐19. A significant association was found between higher daily caregiver burden and more difficult care experiences during COVID‐19 pandemic lockdowns (B = 0.58, 95% confidence interval, 0.40‐0.75, P < .01, adjusted R‐squared = .34).

Conclusions

Further studies and supports for caregivers of people with schizophrenia are needed.

This study showed care difficulties experienced by caregivers of people with schizophrenia during COVID‐19 pandemic lockdowns in Japan and its association with daily caregiver burden.

Assessing stable validity and reliability of the Japanese version of the individualized supported employment fidelity scale: A replication

Background

The Japanese version of the individualized Supported Employment Fidelity scale (JiSEF) was developed by modifying the 25‐item Individual Placement and Support Fidelity Scale (IPS‐25). While a preliminary study partly confirmed the concurrent validity with vocational outcomes, this replication study aimed to examine the stability of the concurrent validity and the inter‐rater reliability of the JiSEF and to test its convergent validity with IPS‐25.

Methods

Fidelity assessments were conducted in 2016 (n = 17), 2017 (n = 13), and 2018 (n = 18) to examine the employment rate and the fidelity scores at the agency level. We also evaluated the fidelity scores for the IPS‐25 in 2018. We examined the associations between the fidelity scale scores and vocational outcomes for the concurrent validity and between the fidelity scales for convergent validity. The inter‐rater reliability was examined in the 2016 and 2017 assessments.

Results

High intraclass correlation coefficients (0.93 in 2016 and 0.92 in 2017) were obtained for the inter‐rater reliability. The JiSEF score in each year was associated with the agency employment rate (r = 0.710, P = 0.001 in 2016; r = 0.722, P = 0.005 in 2017; and r = 0.665, P = 0.003 in 2018). A supplementary longitudinal data analysis also confirmed the association between the JiSEF score and the employment outcomes. Additionally, the JiSEF was significantly correlated with the IPS‐25 (r = 0.760, P < 0.001).

Conclusions

This study stably replicated good inter‐rater reliability and concurrent validity of the JiSEF. Additionally, the convergent validity was confirmed. Further studies with large samples are needed to confirm these findings.

This study stably replicated a good inter‐rater reliability and concurrent validity of the Japanese version of the individualized Supported Employment Fidelity scale (JiSEF).

Anxiety and Depression Symptoms and Suicidal Ideation in Japan Rugby Top League Players

Clinical and research interest is growing in mental health support for elite athletes, based on findings from epidemiological surveys conducted in Australia, the United States, and European countries. However, little is known about the mental health status of elite athletes in Asia, including Japan. In the current study, we examine the prevalence of mental health problems and suicidal ideation and its risk factors in Japan Rugby Top League players. We analyze anonymous web-based self-reported data from 251 currently competing Japan Rugby Top League male players. During the off-season from December 2019 to January 2020, data on anxiety and depression symptoms were collected using the Japanese version of the 6-item Kessler-6. Suicidal ideation was assessed using the Baron Depression Screener for Athletes. Among the players, 81 players (32.3%) had experienced symptoms of mild anxiety and depression during the previous 30 days, while 12 (4.8%) and 13 (5.2%) had suffered from moderate and severe symptoms, respectively. Nineteen athletes (7.6%) reported that they had experienced suicidal ideation during the previous 2 weeks. Players with mental health problems experienced more events in competitions and daily life, including reduced subjective performance, missing opportunities to play during the last season, changes in health condition, and thinking about a career after retirement, compared with players without such problems. Mental health issues in Japan Rugby Top League players, as elite athletes, may be common, and research and practice development is expected in the near future.

Validity of Short-Term Assessment of Risk and Treatability in the Japanese Forensic Probation Service

This study aimed to evaluate the predictive validity and reliability of the Short-Term Assessment of Risk and Treatability (START) in the context of the Japanese forensic probation service. START is a structured professional judgement guide for risk domains concerning negative behaviors such as violence, self-harm, suicide, substance abuse, unauthorized leave, victimization, and self-neglect. In this study, rehabilitation coordinators evaluated community-dwelling patients who were treated under the Medical Treatment and Supervision Act at baseline and followed-up for 6 months. The results revealed that START vulnerability scores significantly predicted self-harm, suicide, physical aggression, substance abuse, and self-neglect. START strength scores predicted physical violence and unauthorized leave. Specific risk estimates predicted physical violence and self-neglect. Risk judgement for future substance use may require adjustments for cultural differences, because of the lower prevalence in Japan. These results suggest that START offers a feasible and valid tool that allows clinicians to plan treatment and promote recovery of forensic patients in Japan.

Is intensive case management screening sheet score associated with service intensity?

AIMS

Since April 2020, the new Japanese mental health system has used the Intensive Case Management Screening Sheet (ICMSS) to identify patients' needs for case management services. This study aimed to examine the association between ICMSS score and service intensity and compare the magnitude of association between ICMSS score and service intensity with other scales.

METHODS

We recruited patients who received case management services from a staff member in a psychiatric outpatient service, psychiatric day-care program, or outreach team based at one psychiatric hospital. Case management service needs and functioning were assessed using ICMSS, Global Assessment Functioning (GAF), and Personal and Social Performance (PSP). The case manager also documented all services received by the participant for 2 months. The association between each scale and service duration was examined. Furthermore, the magnitude of the association between each scale and service intensity was compared.

RESULTS

Overall, 138 participants were included in the analysis. The most common diagnosis was schizophrenia. Mean total service duration was weakly but significantly correlated with ICMSS (Spearman's ρ = 0.320), GAF (ρ = -0.198), and PSP (ρ = -0.275) scores. Poisson's regression models and postestimation testing showed that the coefficient for ICMSS score (B = 0.144; 95% CI = 0.141, 0.148) was significantly larger than the coefficients for GAF (B = -0.017, 95% CI = -0.017, -0.016, χ2  = 15.70, P < 0.001) and PSP (B=-0.016, 95% CI = -0.017, -0.016, χ2  = 14.64, P < 0.001) scores.

CONCLUSION

ICMSS may provide preliminary information on case management service needs, but the level of service should be based on the individual needs of each patient and shared decision-making between the patient and case manager.

Developing a Japanese Version of the Baron Depression Screener for Athletes among Male Professional Rugby Players

The Baron Depression Screener for Athletes (BDSA) is a brief, valid, and reliable athlete- specific assessment tool developed in the US to assess depressive symptoms in elite athletes. We examined the applicability and reliability of a Japanese version of the BDSA (BDSA-J) in a Japanese context, and further examined the construct validity of the BDSA-J. Web-based anonymous self-report data of 235 currently competing Japanese professional male rugby players (25–29 years = 123 [52.3%]) was analyzed. A two-stage process was conducted to validate the factor structure of the BDSA-J using exploratory factor analysis in a randomly partitioned calibration sample, and confirmatory factor analysis in a separate validation sample. Cronbach’s alpha was used to assess internal consistency. Spearman’s rank-order correlation coefficients were calculated to examine convergent validity with the Kessler-6. We identified a one-factor structure for BDSA-J. Confirmatory factor analysis supported this one-factor model, revealing good model fit indices. The standardized path coefficients for each of the items were β = 0.52 to 0.79 (p < 0.001). A Cronbach’s alpha of 0.71 was obtained for the BDSA-J. BDSA-J showed significant positive correlations with the Kessler-6. The BDSA-J is an appropriate and psychometrically robust measure for identifying depressive symptoms in Japanese male rugby players.

Contents and Intensity of Services in Low- and High-Fidelity Programs for Supported Employment: Results of a Longitudinal Survey

OBJECTIVE

Little is known about the association between service intensity and fidelity scale score in supported employment programs. This study compares service contents and intensity in low- and high-fidelity programs and examines the validity of the Japanese version of the individualized Supported Employment Fidelity Scale.

METHODS

The vocational outcomes and service provision data for 51 individuals with schizophrenia in 13 supported employment programs were collected over a 12-month study period. Outcomes, service contents, and service intensity were compared between the low-fidelity group (seven programs; N=29) and the high-fidelity group (six programs; N=22).

RESULTS

In both groups, 70% of the total services (hours) were provided in the first 6 months. The high-fidelity group, which was associated with better vocational outcomes than the low-fidelity group (employment rate, 68% versus 38%, respectively), made the greatest effort in job development outside of the agency, whereas the low-fidelity group spent more time on group services. In addition, before the client obtained a job, high-fidelity programs provided outreach services (B=7.2, p=0.043) and agency-based individual services (B=5.7, p<0.001) at greater intensity than did low-fidelity programs. However, no significant between-group difference was found in service intensity once clients were employed.

CONCLUSIONS

Supported employment programs with a high fidelity score focus more intensely on providing individual services in and outside of the agency, particularly before clients obtain a job. However, clarification of the relationships among service quality at the structure level, amount of follow-up services, and individual needs in supported employment programs is a future issue.

Effects of brief family psychoeducation for caregivers of people with schizophrenia in Japan provided by visiting nurses: protocol for a cluster randomised controlled trial

INTRODUCTION

Development of a support system for families caring for people with schizophrenia in routine psychiatric care settings is an important issue worldwide. Regional mental health systems are inadequate for delivering effective services to such family members. Despite evidence that family psychoeducation (FPE) alleviates the burden of schizophrenia on families, its dissemination in routine clinical practice remains insufficient, suggesting the need for developing an effective and implementable intervention for family caregivers in the existing mental health system setting. In Japan, the visiting nurse service system would be a practical way of providing family services. Visiting nurses in local communities are involved in the everyday lives of people with schizophrenia and their families. Accordingly, visiting nurses understand their needs and are able to provide family support as a service covered by national health insurance. The purpose of this study is to discover whether a brief FPE programme provided by visiting nurses caring for people with schizophrenia will alleviate family burden through a cluster randomised controlled trial (cRCT).

METHODS AND ANALYSIS

The study will be a two-arm, parallel-group (visiting nurse agency) cRCT. Forty-seven visiting nurse agencies will be randomly allocated to the brief FPE group (intervention group) or treatment as usual group (control group). Caregivers of people with schizophrenia will be recruited by visiting nurses using a randomly ordered list. The primary outcome will be caregiver burden, measured using the Japanese version of Zarit Burden Interview. Outcome assessments will be conducted at baseline, 1-month follow-up and 6-month follow-up. Multiple levels of three-way interactions in mixed models will be used to examine whether the brief FPE programme will alleviate the burden on caregivers relative to treatment as usual.

ETHICS AND DISSEMINATION

The Research Ethics Committee of the Graduate School of Medicine and Faculty of Medicine, The University of Tokyo, Japan (No 2019065NI) approved this study. The results will be published in a scientific peer-reviewed journal.

Development of the Interpersonal Processes of Care Survey-Japanese version

AIMS

In the past two decades, there has been growing interest in patient-doctor communication in psychiatry, and several treatment options have been established. This study aimed to develop the Interpersonal Processes of Care Survey-Japanese version (IPC-J), which measures multidimensional communication and the relationship between doctors and patients in Japanese psychiatry.

METHOD

We conducted a cross-sectional questionnaire survey at one psychiatric hospital and two psychiatric clinics in Japan and investigated the factor validity, convergent validity, internal consistency, and test-retest reliability of the IPC-J.

RESULT

Overall, 148 eligible patients participated in the study and were included in the analyses. Data from 16 participants were used to examine test-retest reliability. An exploratory factor analysis using 23 items from the IPC scale was performed to clarify the factor structure in a Japanese psychiatric setting. The final IPC-J contained 22 items and a two-factor structural model. High internal consistency (α > .8) and moderate test-retest reliability (interclass correlation > .65) were observed. Regarding convergent validity, the factor 1 "Doctor's communication-related attitudes and skills" was significantly correlated with service satisfaction, empowerment, and medication adherence, whereas the factor 2 "Consideration for the patient's to promote own treatment decisions" was correlated with service satisfaction and medication adherence.

CONCLUSION

The IPC-J appears to be a useful tool for assessing patient views on interpersonal communication with doctors in a Japanese psychiatric setting. While the analysis suggested utilizing an IPC-J with 22 items, the full IPC-J can be used in cross-cultural studies.

Outcomes of administrative involuntary hospitalization: A national retrospective cohort study in Japan

BACKGROUND

Treatment for offenders with mental disorders is a key concern in public mental health. Provision of adequate psychiatric treatment is important for the offender and their community. An approach used in Japan to address this issue is administrative involuntary hospitalization. Under this scheme, a person at risk for harming themselves or others because of a mental disorder can be involuntarily hospitalized in a designated psychiatric hospital. However, this scheme does not include tracking of these patients after discharge. Although some data for administrative involuntary hospitalizations are available, it remains unclear what happens to these patients after discharge.

AIM

To evaluate follow-up of patients under administrative involuntary hospitalization after discharge and obtain data for later comparisons with outcomes.

METHODS

We used a retrospective design and conducted a national survey of administrative involuntary hospitalizations. Questionnaires were distributed to 939 facilities across Japan. The questionnaire collected data for selected involuntary hospitalization cases in the hospital on June 30, 2010 (census date), and the prognoses of each patient on a specified date in 2011 and 2012. We also asked about the treatment provided to each patient. We stratified patients by prognosis (good or poor), and used logistic regression analysis to examine the relationship between treatment and prognosis.

RESULTS

We received completed questionnaires from 292 facilities (response rate 31.1%); 105 facilities had no relevant patients. Our analysis included data for 394 patients with valid data. Official statistics indicated 1503 patients were under administrative involuntary hospitalization as at June 30, 2012, meaning the capture rate was 27.2%. Approximately a fourth (104/394) at 1 year, and a third (137/294) at 2 years after the census had unknown prognosis. Treatment content included multi-disciplinary team meetings (78.2% of patients), counseling by public workers (59.9%), and discussion with external specialists (32.5%). Overall, 116 patients were categorized as having a good prognosis at 1 year, and 168 had a poor prognosis. At the 2-year point, 102 patients had a good prognosis and 150 had a poor prognosis. “Discussion with external specialists” was positively associated with a good prognosis at both 1 year (P = 0.016) and 2 years (P = 0.036).

CONCLUSION

We found that facilities in Japan currently have limited ability to track the prognoses of patients who were hospitalized involuntarily. Discussion with external specialists is associated with a good prognosis.

Core services of intensive case management for people with mental illness: A network analysis

BACKGROUND

In intensive case management (ICM), users receive a wide variety of services of varying content, which makes it difficult to understand the global features of ICM programs.

AIMS

The aim of this study was to examine the features of ICM programs using network analysis.

METHODS

A total of 233 ICM users in two Japanese medical institutions were recruited to participate. All received services were recorded for 2 months. In the network analysis, nodes represented types of ICM services and edges between two nodes depicted when over 5% of participants received both types of services.

RESULTS

We found high centrality values for 'H5. Hospital-based counseling', 'O13. Outreach support for mental health medications', 'H13. Hospital-based support for mental health medication', 'T5. Counseling via telecommunication', 'H3. Hospital-based coordination of services in the medical institution' and 'T2. Coordination of services with other institutions via telecommunication'. These results indicated that these services were associated with various other types of services. Social functioning was related to 'O13. Outreach support for mental health medication', whereas need for ICM was related to 'H13. Hospital-based support for mental health medications', 'T5. Counseling via telecommunication' and 'T2. Coordination of services with other institutions via telecommunication'.

CONCLUSION

Based on these findings, we speculated that there are at least five types of core services in ICM: regular face-to-face contact, outreach services, hospital-based services, easy contacts and coordination. These findings clarified the features of ICM programs, which may help improve the understanding of case managers' practice.

Psychometric Properties of Scale to Assess the Therapeutic Relationship-JapaneseVersion (STAR-J)

Background: A good therapeutic relationship between patient and psychiatrist is vital for effective mental health care. However, no instruments to assess this relationship are available in Japan. This study aimed to develop a Japanese version of a Scale To Assess Therapeutic Relationship (STAR-J), which measures such relationships from the viewpoints of both the patient (STAR-J-P) and clinician (STAR-J-C). We examined the tool's psychometric properties, including factor structure, internal consistency, convergent validity, and test-retest reliability among psychiatric outpatients and psychiatrists. Methods: Study participants comprised 139 outpatients and 10 psychiatrists. Exploratory factor analysis was conducted to investigate factor structure; to confirm cross-validity, confirmatory factor analysis was conducted using a different sample constituting 195 participants in an assertive community treatment program and their 91 case managers. Cronbach's alpha was used to assess internal consistency. For STAR-J-P only, the intra-class correlation coefficient (ICC) was computed for 17 patients to determine test-retest reliability. Spearman's correlation coefficients were calculated to examine convergent validity with service satisfaction, empowerment, and medication adherence. Results: We identified a two-factor structure for STAR-J-P and a one-factor structure for STAR-J-C. Cronbach's alphas for the two STAR-J-P factors were 0.897 and 0.645, and that for the STAR-J-C factor was 0.949. The ICCs for STAR-J-P factors 1 and 2 were 0.765 and 0.630, respectively. STAR-J-P and STAR-J-C were not significantly correlated. STAR-J-P factors 1 and 2 showed significant correlations with service satisfaction (factor 1: ρ = 0.648, p < 0.001; factor 2: ρ = 0.238, p = 0.005) and medication adherence (factor 1: ρ = 0.508, p < 0.001; factor 2: ρ = 0.347, p < 0.001), but only factor 1 showed a significant relationship with empowerment (ρ = 0.283, p = 0.001). STAR-J-C was significantly correlated only with empowerment (ρ = 0.207, p = 0.017). Conclusions: STAR-J appears to be a useful instrument for assessing therapeutic relationships in the Japanese psychiatric outpatient setting. Further studies should test its validity and applicability in different mental health service settings.

Associations between readmission and patient-reported measures in acute psychiatric inpatients: a study protocol for a multicenter prospective longitudinal study (the ePOP-J study)

Background

Several previous observational studies have reported the risk factors associated with readmission in people with mental illness. While patient-reported experiences and outcomes have become increasingly important in healthcare, only a few studies have examined these parameters in terms of their direct association with readmission in an acute psychiatric setting. This project will investigate multiple factors associated with readmission and community living in acute psychiatric patients in Japan. This study will primarily investigate whether patient-reported experiences at discharge, particularly quality of life (QoL), are associated with future readmission and whether readmission after the index hospitalization is associated with changes in patient-reported outcomes during the study period. Here, we describe the rationale and methods of this study.

Methods

This multicenter prospective cohort study is being conducted in 21 participating Japanese hospitals, with a target sample of approximately 600 participants admitted to the acute psychiatric ward. The study has four planned assessment points: time of index admission (T1), time of discharge (from the index admission) (T2), 6 months after discharge from the index admission (T3), and 12 months after discharge from the index admission (T4). Participants will complete self-reported measures including a QoL scale, a subjective disability scale, and an empowerment- and self-agency-related scale at each assessment point; additionally, service satisfaction, subjective view of need for services, and subjective relationships with family members will be assessed at T2 and T3. We will assess the participants’ hospitalization during the study period and evaluate several potential individual- and service-level factors associated with readmission and patient-reported experiences and outcomes. Multivariate analyses will be conducted to identify potential associations between readmission and patient-reported experiences and outcomes.

Discussion

The present study may produce evidence on how patient-reported experiences at discharge influence readmission and on the influence of readmission on the course of patient-reported outcomes from admission to community living after discharge. The study may contribute to improving care for both patients’ subjective views of their own health conditions and their community lives in an acute psychiatric setting.

Development and evaluation of Intensive Case Management Screening Sheet in the Japanese population

Background

In Japan, the mental health system has been shifting from hospitalization-based to community-based care; some organizations have gradually begun providing intensive case management (ICM) services. We developed an Intensive Case Management Screening Sheet (ICMSS) to screen for the need for ICM in people with mental illness.

Methods

The aim of this study was to examine the psychometric properties and discriminative ability of ICMSS. Subjects consisted of 911 people with mental illness. The ICMSS score was rated by a professional such as a nurse, social worker, or occupational therapist.

Results

Exploratory factor analysis showed a one-factor structure with 14 items. The factor structure was supported by confirmatory factor analysis (comparative fit index, 0.98; Tucker–Lewis index, 0.97; root mean square error test of close fit, 0.05). In the receiver operating characteristic analysis for discriminating between users and non-users of ICM services, the area under the curve (AUC) for ICMSS was significantly larger than for Global Assessment of Functioning and Personal and Social Performance Scale, indicating better discriminative ability. However, the AUC for ICMSS was moderate. Thus, we suggest that the need for ICM services is determined by quantitative assessment (i.e., ICMSS) and clinical judgment.

Conclusion

ICMSS is a brief tool for mental health professionals that will be useful in routine clinical practice. We expect that ICMSS will be used as a measure that reflects the views of professionals from various disciplines in Japanese institutions.

Violence Towards Family Caregivers by Their Relative with Schizophrenia in Japan

There have been several violence-related deaths in Japan due to family violence by persons with severe mental illness against their caregivers. However, it is not often acknowledged that these violent acts are mainly directed at family members. This study aimed to clarify what acts of violence family caregivers experienced from their relative with schizophrenia, and how frequently these violent incidents occurred in their lifetime. We also examined caregivers' thoughts of death about themselves and their relatives, as well as their consultation efforts and escape from the violence perpetrated by their relative. Of the 277 caregivers, 87.7% had experienced psychological violence and 75.8% had experienced physical violence perpetrated by their relative. Of 210 caregivers who had experienced physical violence, 26.7% had thought of murder-suicide and 31.0% had wished for their relative's death. Family violence by persons with schizophrenia is not rare but a common occurrence in Japan and may have fatal consequences.

Development of Japanese version of King's Stigma Scale and its short version: Psychometric properties of a self-stigma measure

AIM

The study aimed to develop two Japanese versions of King's Stigma Scale, a full version (KSS-J-1) and a short version (KSS-J-2), through psychometric property testing.

METHODS

The sample included 112 people with mental illness. We tested the constructs of the scales using both confirmatory and exploratory factor analyses. Internal consistency and test-retest reliability were tested. We examined convergent validity with self-esteem or perceived stigma, and different group validity, using the Kessler Psychological Distress Scale (K6).

RESULTS

Whereas a relatively weak model fit (comparative fit index = 0.66, Tucker-Lewis index = 0.63, root mean square error of approximation = 0.097) of KSS-J-1 (full version: 28 items) was found, KSS-J-2 (short version: 17 items), produced by exploratory factor analysis, had a moderate model fit (comparative fit index = 0.90, Tucker-Lewis index = 0.89, root mean square error of approximation = 0.063). High internal consistency (KSS-J-1, ω = 0.82-0.89; KSS-J-2, ω = 0.86-0.89) and moderate test-retest reliability (KSS-J-1, interclass correlation = 0.56-0.88; KSS-J-2, interclass correlation = 0.45-0.85) were reported. Some subscales and the entire scale of KSS-J-1 were significantly correlated with self-esteem and perceived stigma. Conversely, only two subscales in KSS-J-2 were significantly correlated with self-esteem. The scores of each subscale and the entire score for both KSS-J-1 and KSS-J-2 in the high psychological distress group were higher than the low group (KSS-J-1, d = 0.61-0.83; KSS-J-2, d = 0.47-0.70), except for the Discrimination subscale in KSS-J-2.

CONCLUSION

Both Japanese versions of King's Stigma Scale can be utilized depending on their intended use.

Excess mortality in persons with severe mental disorders: a multilevel intervention framework and priorities for clinical practice, policy and research agendas

Excess mortality in persons with severe mental disorders (SMD) is a major public health challenge that warrants action. The number and scope of truly tested interventions in this area remain limited, and strategies for implementation and scaling up of programmes with a strong evidence base are scarce. Furthermore, the majority of available interventions focus on a single or an otherwise limited number of risk factors. Here we present a multilevel model highlighting risk factors for excess mortality in persons with SMD at the individual, health system and socio-environmental levels. Informed by that model, we describe a comprehensive framework that may be useful for designing, implementing and evaluating interventions and programmes to reduce excess mortality in persons with SMD. This framework includes individual-focused, health system-focused, and community level and policy-focused interventions. Incorporating lessons learned from the multilevel model of risk and the comprehensive intervention framework, we identify priorities for clinical practice, policy and research agendas.

NFκB2 Gene as a Novel Candidate that Epigenetically Responds to Interval Walking Training

Physical fitness has been reported to decrease the risk of lifestyle-related diseases. The present study evaluated genome-wide methylation under the hypothesis that interval walking training (IWT) imparted beneficial effects on health, particularly by epigenetically ameliorating susceptibility to inflammation. We screened DNA from peripheral blood samples via genome-wide microarray for genes whose methylation was affected by IWT, paying special attention to promoter regions, and identified over 40 hyper- or hypo-methylated genes following IWT that were not witnessed in controls. We next selected genes in which the degree of methylation change in the promoter region was correlated with energy consumption following IWT. In this way, we found the NFκB2 gene to have increased methylation in multiple regions of its promoter sequence following participation in an exercise regimen. Next, IWT-induced NFκB2 hyper-methylation was confirmed by a quantitative PyroSequencing assessment of methylation in samples obtained from independent subjects who also underwent IWT. The increase in NFκB2 gene promoter methylation by IWT indicates that this regimen may suppress pro-inflammatory cytokines. Thus, these results provide an additional line of evidence that IWT is advantageous in promoting health from an epigenetic perspective by ameliorating susceptibility to inflammation.

Differences between subjective experiences and observed behaviors in near-fatal suicide attempters with untreated schizophrenia: a qualitative pilot study

BACKGROUND

In cases of untreated schizophrenia, the patients' entourage often does not recognize the psychotic symptoms of the patient and the possibility that the patient may attempt suicide. The aim of this study was to investigate the discrepancies between the subjective experiences and observed behaviors in near-fatal suicide attempters with untreated schizophrenia.

METHODS

A semi-structured interview was carried out with seven near-fatal suicide attempters with untreated schizophrenia to examine the subjective experiences at the time of the suicide attempt. The families of the patients were also interviewed to determine their recognition of the patients' psychotic symptoms and the suicidal ideation. The interview data were analyzed qualitatively.

RESULTS

Six subjects were undergoing exacerbation of the psychotic symptoms at the time of exhibiting the suicide-related ideation. One subject had been in a prolonged depressive state before attempting suicide. Although all the patients experienced severe distress due to psychotic symptoms and depressive mood, they all exhibited only low level or no help-seeking behavior, and six of seven families had not recognized the change in the patient's mental condition.

CONCLUSIONS

Appropriate information about schizophrenia should be provided to the general public so that any help-seeking by the patients with this disease is not overlooked. In addition, accessible early intervention services for psychosis should be established.

Development of forensic mental health services in Japan: working towards the reintegration of offenders with mental disorders

Background

Until the recent enactment of the Medical Treatment and Supervision Act (MTSA) in 2005, neither legislations nor facilities for mentally disordered offenders were available in Japan. The aim of the country’s forensic mental health services, based on this new law, is to improve the social reintegration of mentally disordered offenders. In order to provide optimal psychiatric care to these individuals, specialised court proceedings, treatment facilities, and concrete guidelines have been established. The aim of this study was to review the current status of the new system and to clarify future challenges for improving services.

Methods

The authors collected official statistics regarding the new system published separately by the Ministry of Health, Labour and Welfare, the Ministry of Justice, and the Supreme Court of Japan. We aggregated the data and examined the system’s current implementation status, nationwide.

Results

There were 2,750 requests for enrolment in the MTSA system between its initiation in 2005 and 31 December 2012. Of those requests, 2,724 cases had been concluded in court. In 63.1% of the cases, an inpatient treatment order had been made; 82.4% of those inpatients were diagnosed with schizophrenia. By the end of March 2012, two patients completing treatment under the MTSA had re-committed a serious offense. While overall designated inpatient and outpatient treatment facilities have reached national targets in terms of resources and beds available, a regional gap in MTSA designated facilities remains and the number of patients under inpatient treatment order is on the increase.

Conclusions

Overall, the MTSA system has been running smoothly without encountering any serious problems. However, several concerns have emerged, such as the accumulation of patients under inpatient treatment order and insufficient regional resources. To more successfully promote the reintegration of mentally disordered offenders, improvements in outpatient treatment and welfare services are crucial. In order to install effective measures to help improve the system, a nationwide database of patients being treated under order of the MTSA should be properly built and maintained.

[Survey regarding mental health conditions of high school students and attitudes of students and their teachers toward students' mental health issues]

We administered a self-reporting questionnaire survey regarding the mental health conditions of high school students and attitudes of students and their teachers toward students' mental health issues. In addition, we discussed the requirements for high school students' mental health support system. The subjects were 3,312 students and 208 teachers in four Shizuoka prefectural public high schools in 2009. University Personality Inventory (UPI) is usually conducted to assess university students' mental state and is a questionnaire that high school students can answer easily. Therefore, we adopted UPI for this survey. UPI was composed of 56 unhealthy and 4 healthy condition items. High school students completed the UPI and determined the sum of unhealthy condition items; a higher score indicated a poorer mental health status. The average UPI score of all students (n = 3,312) was 12.7 points, and that of females (n = 1,217)was 15.2 points, which was significantly higher than the 11.3 points of males (n = 2,095). Those with scores > or = 30 points (7.5%), which was more than half of the maximum score, were designated as the High Score (HS) group and considered to have poor mental health. Those with scores of > or = 40 (1.4%) seemed to have very poor mental health, and there was concern that they may be suffering from psychosis. Our observations indicated that HS students were likely to avoid seeking help regarding mental health issues, which was especially true for male HS students. The majority of students chose their friends and parents as advisers, but HS students were significantly more likely to choose advisers who were engaged in jobs related to medical work. Students in both the HS and non-HS groups who did not wish to consult anyone else about their mental conditions wanted to be approached by those around them. High school teachers hesitated to intervene with mentally disturbed students and attempted to resolve problems within the school. Thus, it appears necessary for families, school teachers, and psychiatrists to build closer relations with each other to promote mental health among high school students.

[Psychological trauma risks among disaster workers: perspectives on their mental health following the Great East Japan Earthquake]

Following the March 11, 2011 Great Japan East Earthquake and the Fukushima Daiichi Nuclear Power Plant accident, disaster workers have been working day and night for recovery efforts. A large part of disaster workers, i.e., Self-Defense Force, police, fire department, and coast guard personnel, were highly acknowledged by the Japanese public for searching nearly 19,000 dead or missing victims. This recognition will be beneficial for their psychological recovery. On the other hand, dentists and government employees also took a large role in these mortuary missions, but their work was hardly known to the people. Furthermore, local government employees became victims of public criticisms. Similar phenomenon has been seen among Fukushima nuclear plant workers. These workers have experienced a whole array of traumatic stress, including near-death work experiences, irradiation fear, loss of their properties and their loved ones. The electric company has been blamed by the public for their disaster responses, so the public portrays these employees as disaster perpetrators. However, this trend is leading to serious discriminations and harassments, and adversely affecting their mental health. We all hope the recovery efforts to complete as soon as possible. However, when people criticize these workers, their burden of psychological trauma will continue to grow, and their recovery process will be impeded. It is crucial for the society to recognize these hard-working people and to show appreciation and support for their dedications.

[Complexities of the stress experienced by employees of the Fukushima nuclear plants]

Fukushima Daiichi Nuclear Power Plants suffered serious damage by the Great East Japan Earthquake and Tsunami. The employees of the plant worked very hard to stabilize the nuclear reactor and to prevent any secondary accidents. They were in one of the most severe situations in this disaster, but they were the people who hesitated most to request help for themselves. We started visiting the Fukushima Daini Plant office that was used as the frontline base for Daiichi Plant workers since July, 2011. These visits were held once or twice a month and we offered mental health support to the employees. We have completed interview with the total number of 339 plant workers by April, 2012. We offered several ways of mental support including clinical treatment, continuous counseling, or one time advice, depending on mental condition of each interviewee. Complexity of huge disaster and individuality of suffering from it were discussed in this article. Like local residents, many plant workers also experienced death/missing of family, loss of housing, refuge life, and dispersion of family. Furthermore, they have been suffering from various kinds of criticism and slander against Tokyo Electric Power Company. Many workers, even though they were not in management positions, seemed to have guilty conscience and sense of responsibility that forced them to stay in the risky working site. We could find some struggling coexistence of sense of guilt (as a causer of disaster) and sense of victim in their mind. It was suggested that continuous effort to listen and pay attention to their talk is important in order to support their mission to stabilize the power plant and to prevent them from over-stress and burnout.

Accelerated hepatocellular carcinoma development in mice expressing the Pim-3 transgene selectively in the liver

Pim-3, a proto-oncogene with serine/threonine kinase activity, was enhanced in hepatocellular carcinoma (HCC) tissues. To address the roles of Pim-3 in HCC development, we prepared transgenic mice that express human Pim-3 selectively in liver. The mice were born at a Mendelian ratio, were fertile and did not exhibit any apparent pathological changes in the liver until 1 year after birth. Pim-3-transgenic mouse-derived hepatocytes exhibited accelerated cell cycle progression. The administration of a potent hepatocarcinogen, diethylnitrosamine (DEN), induced accelerated proliferation of liver cells in Pim-3 transgenic mice in the early phase, compared with that observed for wild-type mice. Treatment with DEN induced lipid droplet accumulation with increased proliferating cell numbers 6 months after the treatment. Eventually, wild-type mice developed HCC with a frequency of 40% until 10 month after the treatment. Lipid accumulation was accelerated in Pim-3 transgenic mice with higher proliferating cell numbers, compared with that observed for wild-type mice. Pim-3 transgenic mice developed HCC with a higher incidence (80%) and a heavier burden, together with enhanced intratumoral CD31-positive vascular areas, compared with that observed for wild-type mice. These observations indicate that Pim-3 alone cannot cause, but can accelerate HCC development when induced by a hepatocarcinogen, such as DEN.

Subjective assessments of the quality of life, well-being and self-efficacy in patients with schizophrenia

AIM

The present study examined three kinds of subjective assessment scales in the same patient group with schizophrenia to analyze the correlations among scores obtained in relation to the background data.

METHOD

Thirty-six patients with schizophrenia were examined with the 26-item short form of the World Health Organization Quality of Life (WHO-QOL 26), Subjective Well-being under Neuroleptic drug treatment: Short Japanese version (SWNS) and Self-Efficacy for Community Life scale (SECL) for subjective assessment scales, five kinds of neurocognitive tests, Positive and Negative Syndrome Scale (PANSS) for clinical symptom, Social Functioning Scale (SFS), and Global Assessment of Functioning (GAF) scale for social functioning.

RESULT

The scores for delusions (components of positive syndrome), anxiety and depression (components of general psychopathology) on the PANSS significantly correlated with QoL and subjective well-being scores. In contrast, the scores for components of negative syndrome were not correlated with the subjective assessment scores. Furthermore, none of the clinical symptom scores were correlated with the score in self-efficacy scale. The SFS and GAF scores were significantly correlated with the subjective assessment scores. There were significant correlations among the scores on the three subjective assessment scales.

CONCLUSION

Each scale has different features and should be utilized depending upon the expected effect of treatment or the purpose of assessment. The treatments provided to patients must be directed at improving both psychological and social impairments, in order to enhance the social functioning and QoL of patients.

Multicenter phase II study of a frozen glove to prevent docetaxel-induced onycholysis and cutaneous toxicity for the breast cancer patients (Kinki Multidisciplinary Breast Oncology Group: KMBOG-0605)

Abstract #4093

Background: We have learned from the questionnaire survey of description and hearing type that the onycholysis and skin toxicity occur in approximately 90% of patients(pts) treated with docetaxel (DTX) on hands and 65% on feet. Besides neurotoxicity and edema, these adverse events cause the worse quality of life (QOL) assessment because of the exposure, public noticed site. According to the report that the Elasto-Gel frozen glove (FG) was effective for the prevention of DTX-induced onycholysis and skin toxicity (Scotte F, JCO 23, 4424-29, 2005), we have planned to reanalyze the efficacy and safety of FG for Japanese breast cancer pts by the multicenter, prospective phase II study.&#x2028; Patients and Methods: Patients receiving DTX 75 mg/m2 alone or in combination chemotherapy more than 4 cycles were eligible for this case-control study. Each patient on case group wore an FG for a total of 90 minutes on the both hands. Her feet were not protected. The control data was obtained by the questionnaire survey from the pts who had not used FG during the chemotherapy. Onycholysis and skin toxicity were assessed at each cycle by National Cancer Institute Common Toxicity Criteria and documented by photography. This study had accomplished by multidisciplinary approach by nurses, pharmacists, and doctors. Wilcoxon matched-pairs rank test was used.&#x2028; Results: Between March 2006 and May 2007, 70 pts on case and 52 pts on control were evaluated. Median age were similar for each group, 52 [29-74 years] on case and 51 [25-73 years] on control. Onycholysis and skin toxicity were significantly lower in the FG-protected hands compared with the control hands (P = .0001). Onycholysis was grade (G) 0 in 41% v 8%, G1 in 54% v 74%, and G2 to 3 in 4.3% v 18% for the FG-protected hands and the control hands, respectively. For the feet, there was no difference in frequency between pts on case and on control. Skin toxicity was G0 in 76.6% v 44%, G1 in 13.6% v 42%, and G2 to 3 in 4.4% v 14% for the FG-protected hands and the control, respectively. 32 pts (46%) had experienced the deterioration of pigmentation on hands and/or feet, the FG had seemed not to be able to prevent these unfavorable events. Median time to nail and skin toxicity occurrence was not significantly different between the FG-protected and the control hands of feet, respectively. Although one pt (1.4%) experienced discomfort due to cold intolerance, there were no serious adverse events caused by FG.&#x2028; Conclusion: FG significantly reduces the nail and skin toxicity associated with DTX and is a safety tool on supportive care management. This should be provided in general practice widely to improve a patient's QOL.

An association between idiopathic Parkinson's disease and polymorphisms of phase II detoxification enzymes: glutathione S-transferase M1 and quinone oxidoreductase 1 and 2

Individual vulnerability to reactive intermediates and oxidative stress accompanying metabolism of endogenous toxic compounds in the brain may promote the development of PD. Phase II detoxification enzymes such as glutathione S-transferase M1 (GSTM1), NAD(P)H:quinone oxidoreductase 1 (NQO1) and dihydronicotinamide riboside (NRH):quinone oxidoreductase 2 (NQO2) are important as cellular defenses against catecholamine-derived quinones and the oxidative stress that arises as a consequence of their metabolism. We conducted a study of the potential association between idiopathic Parkinson's disease and polymorphisms of GSTM1, NQO1, and NQO2. DNA samples from 111 unrelated outpatients with idiopathic PD and 100 unrelated healthy volunteers were analyzed. GSTM1 deletion polymorphism exhibited no positive association with PD (P = 0.596, odds ratio: 1.135), although GSTM1 were grouped into three genotypes (deletion/deletion, deletion/nondeletion, and nondeletion/nondeletion). In addition, polymorphism of the NQO1 gene caused by a C to T substitution in exon 3 presented no association with PD (P = 0.194, odds ratio: 1.31). However, polymorphism in the form of an insertion/deletion (I/D) of 29 base pairs (bp) nucleotides in the promoter region of the NQO2 gene, which contains four repeats of the putative core sequence (GGGCGGG) of the Sp1-binding cis-element, did associate with PD. The frequency of the D allele was significantly higher in patients with PD than in controls (P < 0.0001, odds ratio: 3.463). Our data suggested that the deletion of 29-bp nucleotides in the promoter region of the NQO2 gene associates with the development of PD.

Difference in the way of macrophage recognition of target cells depending on their apoptotic states

Dying cells are selectively eliminated from the organism by phagocytosis. Previous studies suggested the existence of some other phagocytosis marker(s) that function together with phosphatidylserine, the best-characterized phagocytosis marker. We obtained here a monoclonal antibody named PH2 that inhibited macrophage phagocytosis of late apoptotic or necrotic cells, but not of early apoptotic cells. On the other hand, phagocytosis of cells at any time during the process of apoptosis was inhibitable by phosphatidylserine-containing liposomes. Inhibition occurred even when target cells were preincubated with PH2 and separated from unbound antibodies. Moreover, PH2 bound to apoptotic cells at late stages more efficiently than to those at early stages, and it did not bind to normal cells unless their plasma membrane was permeabilized. These results suggest that the putative PH2 antigen is a novel phagocytosis marker that translocates to the cell surface at late stages of apoptosis, resulting in maximal recognition and engulfment by macrophages.

Preoperative diagnosis of obturator hernia by computed tomography in six patients

Obturator hernia is a rare condition, and the prognosis of patients with this condition is poor. A retrospective study was performed on six patients with obturator hernia between 1993 and 1998. They had been diagnosed preoperatively by computed tomography (CT). The initial CT scan of the abdomen, including the pelvic area, revealed an incarcerated bowel in the obturator foramen of all six patients. All patients underwent laparotomy on the day of admission. Resection of the small bowel was performed in three patients, and release of the small bowel was performed in the remaining three patients. There were no perioperative deaths. In elderly women who have evidence by abdominal plain X-ray studies of small bowel obstruction, we recommend performing CT scan of the abdomen, including CT scan of the pelvic area, for detection of obturator hernia.

[Antidotes for poisoning and medication overdosage]

Supportive therapy is crucial in the treatment of severe intoxication. Furthermore, specific antidotes are available to neutralize or prevent the toxic effects of poisoning and overdosage. Recently it has become possible to determine the probable toxicity precisely by plotting plasma poison or drug levels. This is especially appropriate in severely intoxicated patients. We conclude that the screening of blood using special agents is the most important in the treatment of such patients at present.

Superselective embolization for bleeding from duodenal diverticulum: a case report

Duodenal diverticulum is a well-known pathological entity. The majority of patients with this condition are asymptomatic. Although hemorrhage has been described, it is an infrequent complication. We report a patient who presented with massive upper gastrointestinal bleeding with hypovolemic shock, originating from a duodenal diverticulum. The diagnosis was made by emergency angiography. Superselective arterial embolization was performed with a successful outcome. To the best of our knowledge, superselective embolization for hemorrhage originating from a duodenal diverticulum has not previously been described in the literature.
