Summary
Co-constitutive risk messaging (CCR) effectively boosts support for pharmaceutical interventions against dengue fever. This integrated One Health Communication approach also influences climate change policy support, particularly for those doubting human impact.
Area of Science:
- Public Health
- Climate Change Communication
- Behavioral Science
Background:
- Climate change facilitates the spread of mosquito-borne diseases like dengue fever.
- Existing risk communication often addresses climate or health risks separately, not jointly.
- Co-constitutive risk messaging (CCR) integrates climate and health risks into a single intervention, termed One Health Communication.
Purpose of the Study:
- To test the impact of CCR messaging on public support for pharmaceutical interventions and climate change mitigation policies.
- To explore how individual worldviews moderate the effectiveness of CCR messaging.
- To assess the utility of One Health Communication strategies.
Main Methods:
- A pre-registered experiment was conducted with a nationally representative survey sample (N = 2,200).
- Participants were exposed to CCR messages linking climate change and infectious disease risks.
- Support for pharmaceutical interventions and climate policy was measured.
Main Results:
- CCR messages significantly increased support for pharmaceutical interventions for dengue fever.
- Collectivistic worldviews were associated with greater receptiveness to public health risk messaging.
- CCR messages showed a positive impact on climate policy support among climate change doubters.
Conclusions:
- CCR and One Health Communication are effective strategies for increasing support for public health and climate change mitigation.
- Tailoring messages to specific worldviews can enhance communication effectiveness.
- Further research is needed to explore broader applications of CCR.

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...
