Suicide is one of the most critical issues worldwide. In Japan, more than 30 000 people died by suicide every year between 1998 and 2011, and the Japanese government, local governments, and various other agencies have been working on suicide prevention programs to reduce the suicide rate. While the number of suicides is still high (more than 20 000 per year), many specialists are striving to further reduce the number of suicides in Japan. The Japanese government has played a central role in suicide prevention through the enactment of several laws, and in recent years, suicide prevention has shifted from government to community‐specific measures. This review discusses the suicide prevention measures that have been taken so far: (1) policy strategies for suicide prevention by the Japanese government, (2) community suicide prevention, and (3) strategic studies for suicide prevention. Finally, as shown in the ACTION‐J study, we conclude that cooperation among related organizations in the community, not just one institution, is important for future suicide prevention, especially youth suicide prevention.
Aim
Suicide attempters have a high risk of repeated suicide attempts and completed suicide. There is evidence that assertive case management can reduce the incidence of recurrent suicidal behavior among suicide attempters. This study evaluated the effect of an assertive‐case‐management training program.
Methods
This multicenter, before‐and‐after study was conducted at 10 centers in Japan. Participants were 274 medical personnel. We used Japanese versions of the Attitudes to Suicide Prevention Scale, the Gatekeeper Self‐Efficacy Scale, the Suicide Intervention Response Inventory (SIRI), and the Attitudes Toward Suicide Questionnaire. We evaluated the effects with one‐sample t‐tests, and examined prognosis factors with multivariable analysis.
Results
There were significant improvements between pre‐training and post‐training in the Attitudes to Suicide Prevention Scale (mean: −3.07, 95% confidence interval [CI]: −3.57 to −2.57, P < 0.001), the Gatekeeper Self‐Efficacy Scale (mean: 10.40, 95%CI: 9.48 to 11.32, P < 0.001), SIRI‐1 (appropriate responses; mean: 1.15, 95%CI: 0.89 to 1.42, P < 0.001), and SIRI‐2 (different to the expert responses; mean: −4.78, 95%CI: −6.18 to −3.38, P < 0.001). Significant improvements were found on all Attitudes Toward Suicide Questionnaire subscale scores, except Unjustified Behavior. The effect of training was influenced by experience of suicide‐prevention training and experience of working with suicidal patients.
Conclusion
The training program (which was developed to implement and disseminate evidence‐based suicide‐prevention measures) improved attitudes, self‐efficacy, and skills for suicide prevention among medical personnel. Specialized suicide‐prevention training and experience with suicidal patients are valuable for enhancing positive attitudes and self‐efficacy; furthermore, age and clinical experience alone are insufficient for these purposes.
