Why do people die by suicide? Dr. Thomas Joiner and his colleagues attempt to answer this age-old question by exploring two obvious yet insightful assumptions: People die by suicide because they canthat is, they become desensitized to pain and habituated toward violence. And people die by suicide because they want tothey typically have no sense of belonging to a valued group or relationship, and they feel that they have become a burden to loved ones. This book offers a new theoretical framework for diagnosis and risk-assessment of a patients entry into the dark and obscure mental world of suicidality, and for the creation of preventive and public-health campaigns aimed at the disorder. More important, though, the book provides new, effective clinical guidelines for crisis intervention and for therapeutic alliances in psychotherapy and suicide prevention.
