Understanding health literacy measurement through eye tracking

Area of Science:

• Health Communication
• Health Literacy Research
• Human-Computer Interaction

Background:

• Health literacy is crucial for understanding health information.
• Individuals with limited health literacy may struggle to navigate complex health materials.
• Eye-tracking offers insights into visual attention patterns when processing information.

Purpose of the Study:

• To investigate how varying levels of health literacy influence visual attention to health-related information.
• To determine if individuals with lower health literacy focus on irrelevant information.
• To inform improvements in health literacy assessment and educational material design.

Main Methods:

• Utilized eye-tracking technology to monitor visual attention.
• Recruited participants with presumed adequate (university staff) and limited (adult literacy program) health literacy.
• Administered the Newest Vital Sign (NVS) assessment using nutrition labels.

Main Results:

• Lower Newest Vital Sign (NVS) scores correlated with increased viewing time of non-relevant nutrition label information.
• Participants with lower health literacy demonstrated less efficient visual search patterns.
• Eye-tracking revealed differences in information seeking behaviors based on health literacy levels.

Conclusions:

• Health literacy assessments should distinguish between difficulties in interpretation and in locating relevant information.
• Health education materials should be designed to minimize non-relevant content to support individuals with lower health literacy.
• Visual attention patterns measured by eye-tracking can provide a deeper understanding of health literacy challenges.
