The range of initiatives covered is wide, reflecting the complex nature of suicide and hence theneed for a range of approaches. This book will be an essential source for anyone concerned with the design and implementation of effective suicide prevention strategies, including clinicians working with individual patients, strategic policy makers, and researchers.
