The field of behavioral intervention following mass trauma has received high visibility since September 11, 2001. The interest in early intervention has expanded rapidly in the past few years in an attempt to prevent the distress, impaired functioning, and long-term difficulties that so often are associated with exposure to mass violence. While thoughtfully designed and carefully executed randomized controlled trials are critical in establishing best practices, there are few randomized controlled trials following mass violence. Therefore, methods such as case studies and consensus conferences have attempted to provide guidance in the absence of empirical support. A consensus conference on mental health interventions following mass violence assembled experts from around the world to arrive at guidance statements for professionals in this field (http://www.nimh.nih-gov/research/ massviolence.pdf
). In August 2003, two expert panels on assessment/screening and outreach/intervention were conducted to expand on the consensus findings. A book currently is in progress (Ritchie E.C., Watson P., Friedman M., Mental Health Intervention Following Disasters or Mass Violence.
