简要总结
This study will be an online 3-arm randomized controlled trial. Here intervention group 1 will receive the intervention in the form of an animated cartoon "scrollytelling" outlining the various changes and reasons for changes in public health guidelines in the context of nutrition (e.g. recommendations on fat intake). Intervention group 2 will have a scrollytelling on the reasons why public health recommendations always change in the context of infectious disease control (e.g. during the COVID-19 pandemic). And finally, the control group will receive no intervention.
详细描述
The project was initially conceived on Figma, a design platform, enabling our design team to create a user interface. Following this design phase, our experienced developers took over, using the Vue.js framework. Development involved fundamental web languages: JavaScript, CSS and HTML. JavaScript made the interface dynamic for smooth user interaction, CSS applied the detailed visual design conceived on Figma, and HTML structured the application's content. This combination resulted in an application, showcasing Vue.js's effectiveness in application development. Our intervention was the "Changing" application, which was a scrollytelling that, in its two versions (food and pandemic), explained why and how public health guidelines are being changed. The main purpose of the "Changing" application is to explain the reasons for ongoing changes in public health guidelines, using COVID-19 and nutrition as examples.

结局指标
主要结局
Anti-intellectualism
时间窗: Immediately after intervention
Anti-intellectualism can be defined as "the refusal to recognize the pre-eminence of intelligence and the value of the sciences". Richard Hofstadter (1963) described anti-intellectualism generally as " a resentment and distrust of the things of the mind and those who represent it" (Hofstadter 1966). This sentiment is captured through a set of six items measuring attitudes towards various authoritative figures and institutions, including medical doctors, scientists, economists , teachers, expert and the Public Health Agency of Canada (Merkley and Loewen 2021). These attitudes are typically assessed using a Likert scale, a widely used semantic rating system in surveys that offers respondents a nuanced range of responses (typically 5 or 7 options) to gauge their perceptions, attitudes, and opinions accurately. Unlike binary "Yes" or "No" responses, this scale allows for a more detailed understanding of how individuals perceive and intercept the issues under investigation.
