Course Introduction

Terrorism is a relatively new stressor for Americans. Certainly we were fearful of “the bomb” during the Cold War; fall-out shelters were constructed or identified all over the country. But the prevailing thinking at that time was that governments (that is, the former Soviet Union) would not use an atomic bomb because it would unleash a destructive cascade that was more horrific than any government would want or could manage. The goal of nuclear threat in the 1950s and 1960s was that it made everyone pay attention to those with the power; the mere threat of nuclear warfare was a deterrent. That was also a time when our enemies were generally other governments.

The enemies of the United States are now often not countries at all, but groups with political, social, religious or ideological perspectives that include destruction of the US government. These enemies are both foreign and domestic.

For some time now terrorists have aimed at American targets. Americans and American interests have been terrorist targets overseas: the 1988 bomb explosion on Pan Am Flight 103 over Lockerbie, Scotland by Libyan terrorists; the bombing of the military barracks at Khobar Towers in 1996; the bombings of two United States embassies in Kenya and Tanzania in 1998, and the 2000 attack on the USS Cole, all alleged to be the work of Osama bin Laden and Al-Qaeda.

We’ve also had terrorism on our own land. We’ve had domestic terrorism, for example the Unabomber, Ted Kaczynski, who mailed letter bombs across the US for over 20 years and Timothy McVeigh and Terry Nichols, convicted, and in the case of Timothy McVeigh, executed, because of their bombing of the Alfred P. Murrah Federal Building in Oklahoma City in 1995. For decades we’ve experienced the domestic terrorism associated with attacks on abortion clinics and those healthcare providers who provide abortion-related services to women. We’ve experienced the World Trade Center bombing in 1993 and the terrible terrorist attacks of September 11, 2001 in New York City, Washington, D.C. and rural Pennsylvania. We’ve also experienced terrorism in which the source has never been identified: the anthrax attacks in September-November, 2001. Clearly our current threats come not so much from enemy governments, but rather from groups with ideological, religious, economic and political missions.

Among the primary goals of terrorism is the emotional and psychological distress that accompanies the dissemination of fear. Terrorists inflict destruction and despair because they want others to see the devastation and be fearful. The more gruesome the attack, the longer will we remember. Terrorists want the possibility that they will strike to be as causing of chaos as an actual attack. Experience with past events indicates that there may be from 4 to 20 psychological victims for every physical victim in a mass casualty situation (Myers, 2001).

Clearly, the threat of terrorism is destructive; however an actual attack causes significantly greater distress in the population. Disturbances of behavior, affect, and cognition can result directly from the destructive actions of some radiological, chemical and biological weapons. But apart from the specific action of these agents, any incident of terrorism, as well as the threat of terrorism can contribute to disturbances of behavior, affect and cognition. Some of these disturbances will occur acutely and will be brief, others will develop into disorders. Some of these disorders will be treated relatively easily and will resolve, others will have a prolonged effect and will be chronic in nature. Some will have a delay in onset (DiGiovanni, 1999). Effective therapeutic intervention in all these psychological effects of terrorism, both real and threatened, involves a broad range of clinical, social, and administrative actions (DiGiovanni, 1999).

This course will address the various psychological and behavioral human responses to the threat of terrorism and the likely human reactions in the event of another terrorist attack. Therapeutic interventions to mitigate these responses and assist in returning survivors to baseline will also be covered.

As frontline healthcare providers, nurses need to be aware of the various responses that their patients, as well as their colleagues and what they themselves are likely to experience. It is important to be aware of and to prepare for this possibility as these human reactions can either hinder or help the outcomes of such an attack (DiGiovanni, 2003).
