Phase III (1994-Present Day)– Risk Communication Model

Basic Terminology
Hazard: Anything that can cause morbidity (injury) or mortality (death).
Risk: The probability of morbidity (loss of limb or injury) or mortality (loss of life) associated with a specific hazard.

Risk CommunicationThe process by which an individual or group of individuals (risk communicator[s]) stimulates meaning in the minds of another individual or group individuals (receiver[s]) about the morbidity and mortality associated with a specific hazard by means of verbal, nonverbal, and mediated messages.

Future Directions More research is needed on crisis communication in general. More receiver characteristics that could impact perceived Risk. I would like to experimentally test the effect of political
affiliation on people’s perceptions of a source of risk communication.
Currently Risk and Crisis Communication is fairly a theoretical, which needs to change.
