The effects of risk probability, outcome severity, efficacy of protection and access to protection on decision making: A further test of protection motivation theory

The effects of different types of risk information in a simulated decision-making task were investigated to test the predictions of protection motivation theory. In accordance with predictions, outcome severity, efficacy of protection, and access to protection were related to protective decisions. The results are discussed in terms of general utility of this model for a variety of decision-making situations. The aspect of manageability, which is seen as a combination of efficacy of protection and access to protection, was discussed as an essential component for risk decision making.
