Memory for Flu Facts and Myths and Effects on Vaccine Intentions

2014-08-27 03:45:57 | BioPortfolio

Summary

Objectives: To determine whether people systematically misremember the “myths” (false information) as true, and to assess effects on perceptions of risk and behavioral intentions.

Description

Public information campaigns often warn people about false and unreliable medical claims by juxtaposing “myths” and “facts.” The effectiveness of such communications has rarely been assessed. We assessed whether people systematically misremember the “myths” (false information) as true, and to assess effects on perceptions of risk and behavioral intentions.

In an experimental study, participants read either a published CDC flyer on “Facts and Myths” about the flu vaccine, or a “Facts Only” version; a separate control group read no flyer. Participants completed the outcome measures either immediately or after 30 minutes.

Primary measures were memory for information about the flu presented in the flyer, ratings of perceived risks associated with the flu, and personal intentions to get vaccinated in the upcoming season.

After a delay of 30 minutes, participants who read the “Facts and Myths” flyer systematically misremembered myths as facts. Both versions of the flyer had the immediate effect of increasing intentions to get a flu vaccine, compared to the control group. After 30 minutes, however, participants who read the “Facts and Myths” flyer reported lower intentions to get vaccinated, compared to those who read the same flyer with no delay, and compared to all participants who read the “Facts Only” flyer.

In sum, people show a bias to think that incompletely remembered information is true, turning “myths” into “facts.” Hence public information campaigns should emphasize information that is true. Repeating false information, even as a warning, can create the unintended consequence of belief in the information.

Medical and Biotech [MESH] Definitions

Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed or attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The vaccine is usually bivalent or trivalent, containing one or two INFLUENZAVIRUS A strains and one INFLUENZAVIRUS B strain.

Vaccines or candidate vaccines used to prevent infection with viruses from the genus SIMPLEXVIRUS. This includes vaccines for HSV-1 and HSV-2.

Vaccines or candidate vaccines used to prevent PAPILLOMAVIRUS INFECTIONS. Human vaccines are intended to reduce the incidence of UTERINE CERVICAL NEOPLASMS, so they are sometimes considered a type of CANCER VACCINES. They are often composed of CAPSID PROTEINS, especially L1 protein, from various types of ALPHAPAPILLOMAVIRUS.

Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.

Type of declarative memory, consisting of personal memory in contrast to general knowledge.
