Within the domestic preparedness community, there is a growing recognition of the importance of psychosocial issues in weapons of mass destruction (WMD) incidents. Whereas social and behavioral issues were only infrequently considered just a few years ago, they are now coming to be seen as central to consequence management efforts. As a result, discussions in the domestic preparedness community are beginning to consider the extent to which psychosocial effects are addressed in the Federal Response Plan and the degree to which additional preparedness and response steps may be needed. To grapple with this crucial issue, an expert panel was brought together at the International Conference on the Operational Impact of Psychological Casualties from Weapons of Mass Destruction. The panel brought together a wide range of specialists from federal agencies, the armed services, and the academic community. This article summarizes the views and assessments of the panelists as well as their policy recommendations for enhancing preparedness.
