This book is about behavioral emergencies and the association between interpersonal victimization and subsequent suicidality and/or risk for violence toward others. Section I focuses on the differences between behavioral crises and behavioral emergencies and presents an integrative approach to crisis intervention and emergency intervention. Section II discusses the evaluation of suicide risk, risk of violence, and risk of interpersonal victimization in children and adolescents. Sections III and IV explore behavioral emergencies with adults and the elderly, while Section V deals with certain conditions or behaviors that may either need to be differentiated from a behavioral emergency, or understood as relevant to possibly heightening risk. Section VI describes treatments for patients with recurrent or ongoing risks, and Section VII is devoted to legal, ethical, and psychological risks faced by clinicians who work with patients who might be at risk to themselves or others.
