Study to measure the fear of Ebola

Although much of the panic surrounding Ebola has quelled, a recent Gallop poll found that Ebola is among American’s top three health concerns, provoking more fear than cancer and obesity.

It is fear that can be attributed to the virus breaching U.S. soil, says Janet Yang, assistant professor in the Department of Communication.

In a new study supported by an $84,110 Rapid Response Research grant from the National Science Foundation, Yang will survey how the public’s view on Ebola is influenced by its emotional and cognitive responses to the outbreak.

She also will examine how people share and receive medical information, and gauge how willing they are to support government initiatives to fight the virus.

While the fear of contracting an illness can drive people to receive routine tests or eat healthily, it also can lead to irrational behavior and the spread of misinformation.

“One of the reasons people are paying attention to the outbreak is because of how close and frightening it appears,” says Yang.

“The public’s perception of risk comes from a reduction in psychological distance. When we didn’t have any confirmed cases, people were less concerned that they themselves would be affected.”

Yang’s study will examine data from 1,000 participants sampled through a survey. Subjects will be assigned randomly to two experimental conditions: one that emphasizes there are people infected with Ebola in the U.S., and another that stresses the opposite.

Yang will draw conclusions from the data using theory from social psychology and risk communication.

“The findings may improve the design of messages related to risk issues that are perceived to be psychologically distant from the American public — issues such as climate change and overpopulation,” she says.

The data also may inform public policy on risk-related issues, promote an appropriate public response and prevent panic grounded in misinformation, she adds.
