Media exposure to bioterrorism: stress and the anthrax attacks

Area of Science:

• Psychology
• Public Health
• Media Studies

Background:

• Terrorism events, including bioterrorism and 9/11 attacks, can have profound psychological impacts on populations.
• Media coverage plays a significant role in shaping public perception and response to such events, even for those distant from the attacks.
• Understanding the relationship between media exposure and psychological adjustment is crucial for public health preparedness.

Purpose of the Study:

• To examine the impact of media exposure on psychological distress and outlook following anthrax bioterrorism and 9/11 attacks.
• To assess the role of perceived risk in mediating the effects of media exposure on psychological outcomes.
• To analyze the long-term effects of initial versus subsequent media exposure on adjustment to terrorism.

Main Methods:

• A sample of 300 individuals living distant from the attacks were surveyed.
• Measures included direct/indirect terrorism exposure, perceived anthrax risk, psychological distress, and outlook.
• Data were collected 2-3 months and 8 months post-anthrax attack.

Main Results:

• Initial media exposure to anthrax attacks strongly predicted psychological distress.
• Subsequent media exposure predicted negative changes in outlook over time.
• Perceived risk of anthrax exposure predicted distress and outlook but did not mediate media exposure effects.

Conclusions:

• Media exposure is a critical factor influencing psychological responses to bioterrorism.
• The timing and nature of media exposure significantly affect adjustment and outlook.
• Findings aid in predicting and managing public response to future bioterrorism events.
