Summary

Visuals like graphs can effectively communicate health risks. Research shows risk ladders, histograms, and pie charts aid understanding, but more study is needed on optimal formats and public comprehension.

Area of Science:

  • Health Communication
  • Risk Perception
  • Data Visualization

Background:

  • Effective risk communication is crucial for public health decision-making.
  • Graphical displays are increasingly used to convey complex risk information.
  • Previous research has focused on communicating risk magnitudes.

Purpose of the Study:

  • To review the use and effectiveness of graphical displays in risk communication.
  • To identify design considerations for risk-related graphs.
  • To suggest future research directions in visual risk communication.

Main Methods:

  • Literature review of key articles from MEDLINE(R) and PsychInfo(R) databases.
  • Analysis of existing research on graphical displays for risk communication.
  • Consultation with experts in the field of risk communication.

Main Results:

  • The risk ladder shows promise for communicating absolute and relative risks.
  • Histograms and pie charts demonstrate preliminary evidence of aiding risk comprehension.
  • Further research is needed on applying theoretical models and testing various graphical formats.

Conclusions:

  • Graphical displays can be effective tools for communicating risk information.
  • The risk ladder, histograms, and pie charts are promising formats.
  • More research is essential to optimize visual risk communication for public understanding and behavioral change.
