Effectiveness of suicide prevention gatekeeper training for university teachers in Japan.

Suicide is a leading cause of death among Japanese college and university students. Our previous study showed that the gatekeeper training (GKT) program significantly improved competence and confidence in the management of suicidal students in university administrative staff. However, we could not determine which component of the program was effective, nor if this program was effective for university teachers as well. In the current study, 81 university teachers were recruited; 63 of them received a general mental health lecture (MHL) and 18 of them received a 2.5 -h GKT program based on the Mental Health First Aid program. Competence and confidence in managing suicide intervention and behavioral intention as a gatekeeper were assessed by a self-report questionnaire before and immediately after the intervention. As a result, we found a significant improvement in competence in the management of suicidal students in the GKT group compared to the MHL group. We also found significant improvements in confidence in the management of suicidal students and behavioral intention as gatekeepers in the GKT group, although the questionnaires for these outcomes were not validated. The program satisfaction score was significantly higher in the GKT group than in the MHL group. To our knowledge, this is the first study to evaluate a GKT program for university teachers in Japan. By comparing the two groups, we explicitly confirmed that active involvement of the participants is crucial for effective suicide prevention training.

Effects of NRG1 genotypes on orbitofrontal sulcogyral patterns in Japanese patients diagnosed with schizophrenia.

AIM: Numerous reports have described differences in the distribution of orbitofrontal cortex (OFC) sulcogyral patterns between patients with schizophrenia (SZ patients) and healthy controls (HC). Alterations in OFC morphology are also observed in those at high risk for developing SZ and in first-episode SZ, suggesting that genetic associations may be extant in determining OFC sulcogyral patterns. We investigated the association between single nucleotide polymorphisms (SNP) in NRG1 and OFC sulcogyral patterns. METHODS: A total of 59 Japanese patients diagnosed with SZ and 60 HC were scanned on a 1.5-T magnet. Patients were also assessed clinically. OFC sulcogyral patterns were evaluated for each participant, and genotyping was performed for four SNP in NRG1 (SNP8NRG243177, SNP8NRG221533, SNP8NRG241930, and rs1081062). RESULTS: There were significant differences in the distribution of OFC sulcogyral patterns between SZ patients and HC (χ(2) = 6.52, P = 0.038). SZ patients showed an increase in the frequency of Type III expression, which was associated with an earlier age of disease onset (ß = -0.302, F = 4.948, P = 0.030). Although no difference was found in genotype frequencies between SZ patients and HC, an NRG1 SNP, SNP8NRG243177, was associated with Type II expression in SZ patients (ß = 0.237, F = 4.120, P = 0.047). CONCLUSION: Our results suggest that OFC sulcogyral pattern formation in schizophrenia may be associated with NRG1 allele frequency, which is closely related to neurodevelopment.

Effectiveness of suicide prevention gatekeeper-training for university administrative staff in Japan.

AIMS: Suicide is a leading cause of death among Japanese college and university students. Gatekeeper-training programs have been shown to improve detection and referral of individuals who are at risk of suicide by training non-mental-health professional persons. However, no studies have investigated the effectiveness of such programs in university settings in Japan. The aim of this study was to investigate the effectiveness of the gatekeeper-training program for administrative staff in Japanese universities. METHODS: We developed a 2.5-h gatekeeper-training program based on the Mental Health First Aid program, which was originally developed for the general public. Seventy-six administrative staff at Hokkaido University participated in the program. Competence and confidence in managing suicide intervention, behavioral intention as a gatekeeper and attitude while handling suicidal students were measured by a self-reported questionnaire before, immediately after and a month after the program. RESULTS: We found a significant improvement in competence in the management of suicidal students. We also found improvements in confidence in management of suicidal students and behavioral intention as a gatekeeper after training, though questionnaires for those secondary outcomes were not validated. These improvements continued for a month. About 95% of the participants rated the program as useful or very useful and one-third of the participants had one or more chances to utilize their skills within a month. CONCLUSIONS: The current results suggest the positive effects of the training program in university settings in Japan. Future evaluation that includes comparison with standard didactic trainings and an assessment of long-term effectiveness are warranted.

[The activities of Mental Health First Aid-Japan Team].

The Mental Health First Aid (MHFA) program is a training program for non-health professionals that deals with persons with a mental health crisis (Kitchener & Jorm, 2006). The MHFA-Japan team was established in 2007, and a founding member completed a MHFA training program in Melbourne, University of Australia. We consulted with Jorm and Kitchener, and started a Japanese study of the program. Providing the MHFA program for gatekeepers in Japan could help them assess risk factors and refer patients for professional care, and contribute to suicide prevention. Our team cooperated with the gatekeeper training program of the cabinet office of the Japanese government. In addition, this program is applied in instructional activities in the area of the Great East Japan Earthquake.

Suicide intervention skills among Japanese medical residents.

OBJECTIVES: Patient suicide is a tragic occurrence, and it can be a demoralizing experience for medical residents. Few studies, however, have assessed suicide management skills among these front-line healthcare professionals. This study evaluated the self-assessed competence and confidence of medical residents with regard to the management of potentially suicidal patients and assessed the correlation with the residents' background characteristics. METHOD: The authors conducted a multicenter, cross-sectional survey of 114 medical residents in Japan, using a modified version of the Suicide Intervention Response Inventory (SIRI-2), the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8), and a 5-point Likert scale to assess confidence in suicide management. RESULTS: A majority (89.5%) of the residents rated their confidence in managing suicidal patients as Not At All Confident or Rather Not Confident, although most were close to completing their psychiatric rotation. Results on the SIRI-2 suggested intermediate competence in managing suicidal behavior, as compared with that of other healthcare professionals. Competence as indicated by the SIRI-2 score was weakly and negatively correlated with the score for self-perceived Vitality on the SF-8 scale. CONCLUSION: Insufficient skills and lack of confidence in the management of suicidal patients was observed in this sample of Japanese medical residents, thus highlighting the need for improved suicide-management programs for junior medical residents in Japanese hospitals.

Evidence for shared genetic risk between methamphetamine-induced psychosis and schizophrenia.

Methamphetamine (METH) use can provoke psychotic reactions requiring immediate treatment, namely METH-induced psychosis. Although the distinction between METH-induced and primary psychosis is important for understanding their clinical courses, we do not have clear diagnostic procedure by their symptoms. Not only are there similarities between the clinical features of METH-induced psychosis and schizophrenia (SCZ), but there is also epidemiological evidence of a shared genetic risk between 'METH-related' disorders and SCZ, which makes the differentiation of these two conditions difficult. In this study, we conducted a genome-wide association study (GWAS) targeting METH-dependent patients. The METH sample group, used in the METH-dependence GWAS, included 236 METH-dependent patients and 864 healthy controls. We also included a 'within-case' comparison between 194 METH-induced psychosis patients and 42 METH-dependent patients without psychosis in a METH-induced psychosis GWAS. To investigate the shared genetic components between METH dependence, METH-induced psychosis, and SCZ, data from our previous SCZ GWAS (total N=1108) were re-analyzed. In the SNP-based analysis, none of the SNPs showed genome-wide significance in either data set. By performing a polygenic component analysis, however, we found that a large number of 'risk' alleles for METH-induced psychosis are over-represented in individuals with SCZ (Pbest=0.0090). Conversely, we did not detect enrichment either between METH dependence and METH-induced psychosis or between METH dependence and SCZ. The results support previous epidemiological and neurobiological evidence for a relationship between METH-induced psychosis and SCZ. These also suggest that the overlap between genes scored as positive in these data sets can have higher probability as susceptibility genes for psychosis.

[Supporting caregivers for people with alcohol-related problems ways to listen, support, and link with care].

Local caregivers such as psychiatric service providers, mental health welfare workers, and nursing-care staff have a major role to play in the long-term support of survivors of the Great Eastern Japan Earthquake of March 11th, 2011. Alcohol-related problems often cause various problems mentally, physically, economically, and socially. Alcoholics tend to show violent behavior, deny their own alcoholism, cause codependency in significant others, and occasionally relapse. Local caregivers bear the burden of caring for them and feel responsible for their relapse. This leads to exhaustion and discomfort with caring for them. In order to provide continuous and effective support for people with alcohol-related problems, it is important for caregivers to know the nature of the illness, the means and stages of recovery, effective support strategies, and how to enjoy providing support. A Leadership Training course on "Mental Health First Aid (MHFA)" was held in November 2011 for caregivers in Iwate Prefecture. MHFA provides help for people suffering from a mental health problem or in a mental health crisis, developed in Australia by Betty A. Kitchener and Anthony F. Jorm. In 2006, the MHFA-Japan (MHFA-J) Project Team translated the program and modified it to fit Japanese culture. The action plan consists of 5 part: 1) Approach the person, assess and assist with any crises, 2) Listen non-judgmentally, 3) Give support and information, 4) Encourage the person to get appropriate, professional help, 5) Encourage other support/self-help. During the leadership training course, MHFA for anxiety disorder, depression, suicidal thoughts, and alcohol-related problems was introduced, as well as how to train caregivers in experience-based and participatory approaches. The session for alcohol-related problems focused on the process of recovery, including how to deal with relapse, how to listen, how to motivate patients, and how to enjoy being a caregiver. There was also a role-play with two different scenarios: one with a confrontational interview and one with an MHFA-styled interview using a motivational approach. In February 2012, two other seminars focused on alcohol-related problems among the elderly and how to organize a case conference to incorporate requests from participants of the leadership training course. In order to provide long-term support to local caregivers, it is important to convey strategies that focus on caring for others comfortably.
