P-1423 - NOCOMIT-J: a Community Intervention Trial of Multi-modal Suicide Prevention Program in Japan

Abstract

Objective:

The primary goal of this study is to examine the effectiveness of a community-based multimodal intervention program for suicide prevention in regions where the suicide rate was relatively high compared to control regions. The secondary goal was to explore the effectiveness of a community-based multimodal intervention program for suicide prevention in highly populated regions.

Methods/design:

NOCOMIT-J is a community-based large-scale non-randomized controlled trial, involving seven intervention regions with accompanying control regions, all with populations of statistically sufficient size. The program consists of

1. 1) Establishing social support networks in the public health system for suicide prevention and mental health promotion;

2. 2) A primary prevention measures of awareness campaign for the public and key personnel;

3. 3) Secondary prevention measures for screening, counseling and outreach services for high-risk individuals;

4. 4) After-care for individuals bereaved by suicide;

5. 5) Suicide prevention measures especially for individuals with mental illness and work-related problems.

This study protocol was reviewed and approved by the Central Ethics Committee of the J-MISP. Additionally, the regional leaders obtained written authorization from the local governors.

Results/progress:

The intervention started in July 2006, and continued for 3.5 years. Participants are Japanese and foreign residents living in the intervention and control regions, a total of population of 2,120,000 individuals.

Discussion:

Because treatment and prevention of suicide are complex and encompass many factors, success will need multi-sector collaboration. We hope that the results of NOCOMIT-J will help to develop effective strategies to reduce future suicide rate. (ClinicalTrials.gov: NCT00737165)
