Robert Simon’s introductory chapter, "Suicide Risk: Assessing the Unpredictable," is a thorough explication of the possibilities and limitations of suicide risk assessment. The subsequent individual chapters present an up-to-date, comprehensive treatment of almost every aspect of suicide risk assessment: age, gender, social and cultural factors, psychiatric diagnosis, prevention, treatment setting, and type of treatment. Simon and Hales also include special subjects ranging from murder-suicides to the aftermath of suicide not only for family survivors but also for psychiatrists who had been treating patients who killed themselves.
