Approximately 1 million people commit suicide world-wide every year and around 10 million attempt suicide each year. Suicide is a major public health problem throughout the world, major efforts are currently being made to help reduce these numbers. However, suicide is the result of complex interactions between a range of factors, including historical, psychological, cultural, biological, and social, and any approach to treating the problem of suicide has to consider all these factors. The 'Oxford Texbook of Suicidology' is the most comprehensive textbook of suicidology and suicide prevention that has ever been published. It is written by world-leading specialists and describes all aspects of suicidal behaviour and suicide prevention. It presents an overview of research within disciplines covering a wide range of factors, including psychological, cultural, biological, and sociological. The book provides up-to-date information on different kinds of risk and protective factors, epidemiology, theories on suicidal behaviours and public health and healthcare preventive approaches. Throughout, different approaches to suicide prevention and evidence-based examples are presented, alongside descriptions of different organisations designed to prevent suicide. This book will be the key source of reference for both researchers and professionals working in the areas of suicidology and suicide prevention.
