Mapping the Cognitive Architecture of Health Beliefs: A Multivariate Conditional Network of Perceived Salt-Related...

Area of Science:

• Nutrition Science
• Cognitive Psychology
• Public Health

Background:

• Public beliefs on dietary risks like salt intake are complex cognitive systems.
• Misconceptions about salt's health effects are often interconnected.
• Understanding these belief structures is crucial for public health communication.

Purpose of the Study:

• To investigate how individuals structure their beliefs and misperceptions about salt's health consequences.
• To identify latent constructs underlying public beliefs regarding salt and disease associations.
• To analyze the interdependence and asymmetry of these beliefs.

Main Methods:

• International online survey data analyzed using multivariate proportional odds logistic regression (POLR).
• Exploratory and confirmatory factor analyses (EFA and CFA) identified belief constructs.
• Beliefs were modeled as interdependent, controlling for sociodemographics and health awareness.

Main Results:

• Physicians strongly agreed on salt's link to hypertension more than non-medical respondents.
• Beliefs about mortality served as central nodes in the belief network.
• Identified strong associations (e.g., hypertension-heart failure) and cognitive gaps (e.g., atrial fibrillation-stroke).

Conclusions:

• Beliefs about salt's health effects are structured and sometimes asymmetrical, indicating reasoning patterns.
• These findings offer a systems-level perspective on health literacy.
• Insights can inform targeted public health communication and education strategies.
