Public perceptions of information sources concerning bioterrorism before and after anthrax attacks: an analysis of national survey data.

This study examined data from six national surveys before and after the bioterrorist anthrax attacks in the fall of 2001. Public perceptions of information sources regarding bioterrorism were examined. The findings highlighted the importance of local television and radio and of cable and network news channels as information sources. The findings also showed the importance of national and local health officials as spokespersons in the event of bioterrorist incidents. Periodic surveys of public attitudes provide important, timely information for understanding audiences in communication planning.
