It poses a serious public health problem worldwide. It has accounted for nearly 1 million deaths and an estimated 10 million attempted suicides each year. It is estimated that approximately 32% of all suicide deaths have occurred in the Western Pacific Region (Hendin et al. 2008, Yip 2008), which is disproportionately found in this area consisting of 37 countries and areas with a total of 1.78 billion people or about 29% of the world’s population. It is estimated that, in this Region, the suicide rate is calculated to be about 19.3 per 100,000 (De Leo, Milner and Wang 2009). Suicide rates in some countries/ areas like Japan, the Republic of Korea and Taiwan, China have had significant increases recently and remained at historically high levels. Suicide is the leading cause of death among young people in this Region and has caused significant economic losses to society. The full impact of the world’s current economic crisis has yet to be realized, but it’s certain to have an effect on mental health and suicide. It is unfortunate as well that suicide prevention resources are limited and underdeveloped, especially in developing countries, which have the largest need for resources and help. This monograph attempts to set out the basic framework for suicide prevention strategies. It provides details in formulating and evaluating suicide prevention programmes. The public health approaches suggested offer a multilayer intervention model, which has been adopted by a number of developed countries for setting up national prevention strategies. Nevertheless, we want to stress that there is no single solution in dealing with suicide in a heterogeneous environment: one size simply doesn’t fit all. Also, all suicide prevention programmes need to be evaluated. And where we do not have the necessary evidence, we must simultaneously implement novel approaches and rigorously evaluate them. Anything less is undesirable. The importance of evaluation is even more critical in Asia, partly due to culture and limited resources. We have included the details of some well-established suicide prevention programmes worldwide and in the Western Pacific Region. They have been shown effective in reducing the number of suicides and/or its associated outcome v Towards Evidence-Based Suicide Prevention Programmes Preface indicators. We hope that by publishing this monograph more cultural-specific programmes on suicide prevention can be developed in the Region. The more we know, the more we can learn from one another about effective suicide prevention strategies. The need for suicide prevention is increasing, especially in the populous countries in the Region. The applicability of the public health approaches for suicide prevention in developing countries has yet to be established due to the diverse economic and sociocultural backgrounds. There are significant differences in resource availability in implementing suicide prevention programmes among countries in the Region. We highlight important features of some evidence-based programmes. Recognizing the many factors that put people at risk of suicide and protecting them against those factors, we believe that only strategies from multiple levels and disciplines can help in reducing suicides substantially. Effective actions should be evidence-based and multilayered. The effectiveness of prevention programmes
