This dissertation draws on a recently developed model that maps predictors of information seeking and processing strategies within a risk setting. The value of the model---which was developed by Robert Griffin, Sharon Dunwoody and Kurt Neuwirth in the late 90s---lies not in its depiction of each individual relationship but in its effort to map those relationships causally to capture the complexity of a risk information-processing event. An additional strength of the model is its treatment of processing strategies as dependent rather than independent variables
Previous research has applied the model to risks that pose a direct personal threat to individuals (for example, the consumption of contaminated fish or drinking water). This dissertation studies the goodness of fit of that model to risks that pose a more impersonal threat (in this case, the general health of the Great Lakes). Impersonal risks are those risks that pose no direct threat; they pose an indirect personal threat or a direct threat to entities other than the self. Environmental hazards such as global warming, overfishing, and encroachment on wildlife refuges fall into this category of risk
The study finds the model is appropriate for both impersonal and personal threats. However, the extent to which the contributing factors ultimately predict to information processing in both risk situations differs. One example is the contribution made to affect by personal relevance indicators (as represented in the perceived hazard characteristics). One of the most important distinctions between personal and impersonal threats is the role played by perceived personal relevance (e.g., perceived personal risk and worry) in driving information processing styles. These results suggest that risk communicators interested in educating the public about impersonal risks should amplify relevance indicators aside from perceived personal risk when creating the target message
Future research is necessary to determine the most informative and predictive iteration of the model. For example, while the original model portrays most predictors as acting indirectly on information seeking and processing (e.g., through the perceived gap between current information and information needed), this dissertation shows that those variables also have some direct influence on seeking and processing
