Testing Links Among Uncertainty, Affect, and Attitude Toward a Health Behavior

This study examines the conceptual linkages between individuals’ uncertainty judgments and affective reactions (worry and anger) within the context of an environmental health risk. It uses data from a longitudinal study of people’s reactions to the risks of eating contaminated fish from the Great Lakes that employed the risk information seeking and processing model and incorporates a set of variables from the full model, which includes preventive behavior. Findings support the model and indicate that worry and anger strongly influenced uncertainty judgments but worry and anger influenced attitudes toward fish avoidance and information insufficiency differently.
