In this book leading figures from psychiatry, psychology, epidemiology, public health, and social medicine bring together the research evidence concerning the key elements in suicide prevention and treatment of suicidal behaviour and translate it into implications for practical action. This includes social and public health policy as well as clinical practice. The book draws together the evidence relevant to treatment and prevention, and uses this in order to highlight the most effective approaches. The range of initiatives covered is wide, reflecting the complex nature of suicide and hence the need 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.
