Much of this text is devoted to personal histories or written materials from suicidal patients. These are used to illustrate features of suicidal behavior that Dr. Shneidman believes are important for clinicians to learn. For example, he suggests that most suicides fall into five categories of psychological needs: thwarted love, fractured control, shame, ruptured relationships, and excessive anger. Dr. Shneidman lists and discusses what he believes are the 10 commonalities of suicide: search for a solution, cessation of consciousness, unbearable psychological pain, frustrated needs, hopelessness, ambivalence, constricted thinking, escape, communication of intention, and extension of lifelong personality styles.
