1. The primary goal for this study is to examine the effectiveness of community-based multimodal intervention program for suicide prevention in relatively high suicide rate region compared to control region.
2. The secondary goal for this study is to explore the effectiveness of community-based multimodal intervention program for suicide prevention in the highly populated regions. In addition, we examine the effectiveness of the prevention program in the all regions combined.
