For many, thoughts of suicide are abundant and frequent. There exists a fear of death but an even greater fear of life due to the latter’s hardships. Participants of the committee on the Pathophysiology and Prevention of Adult and Adolescent Suicide of the Institute of Medicine’s workshop on suicide prevention; however, believe that there is potential for better suicide prevention. Two workshops were convened by the committee: Risk Factors for Suicide, March 14, 2001 and Suicide Prevention and Intervention, May 14, 2001. The two workshops were designed to allow invited presenters to share with the committee and other workshop participants their particular expertise in suicide, and to discuss and examine the existing knowledge base. Participants of the second workshop were selected to represent many areas including: design and analysis of prevention programs, suicide contagion, and firearm availability and suicide. The committee wanted to assess the science base of suicide etiology, evaluate the current status of suicide prevention, and examine current strategies for the study of suicide.
