Area of Science:

  • Health communication
  • Information science
  • Psychology

Background:

  • Misinformation exposure can lead to health misperceptions.
  • Understanding factors influencing susceptibility to misinformation is crucial.
  • eHealth literacy and motivation are potential moderators.

Purpose of the Study:

  • To investigate the development of health misperceptions post-misinformation exposure.
  • To examine the roles of eHealth literacy and situational motivation.
  • To analyze differential susceptibility among various public types.

Main Methods:

  • Two studies were conducted to assess misperception formation and misinformation amplification.
  • Statistical analyses examined associations between variables.
  • A typology of misinformation-susceptible publics was utilized.

Main Results:

  • Situational motivation positively correlated with misperception formation and misinformation amplification.
  • eHealth literacy showed no significant association with misperceptions or amplification.
  • Misinformation-amplifying publics demonstrated the highest susceptibility.

Conclusions:

  • Situational motivation is a key factor in health misperceptions and misinformation spread.
  • eHealth literacy may not be a protective factor against misinformation effects.
  • Identifying susceptible publics is vital for targeted interventions.
