Clinical Trial Summary

Dime La VerDAD is an innovative social media capacity-building program that empowers promotores de salud to debunk vaccine misinformation through the use of personal narratives on social media. The core of the implementation strategy consists of augmenting training and self-efficacy for natural community champions, "promotores de salud" from the Hispanic community as trusted messengers to debunk vaccination misinformation. Our study will leverage existing community relationships in Chicago and a first of its kind misinformation curriculum to debunk misinformation in communities served by participating promotores de salud. Dime La VerDAD (Verify, Debunk, and Disseminate) is an innovative social media capacity-building program based on theoretical frameworks related to health communication that empowers promotores de salud to debunk vaccine misinformation through the use of personal narratives on social media. This mixed methods study will use a rigorous stepped wedge design to 1) deliver a scalable program of science communicators using an adapted curriculum grounded in infodemiology, 2) evaluate how debunking misinformation is perceived on social media, and 3) discern how use of personal narratives to enhance science communication can lead to changes in opinions and behavior (vaccination rates) about COVID and influenza vaccines among Chicago's predominantly Hispanic communities.

Description:

Social media has accelerated the spread of vaccine misinformation leading to decreased immunization rates and increased preventable deaths in the US and globally. The health impact of misinformation is particularly critical to understand and address when considering the lives of minoritized racial and ethnic groups who are often the target of misinformation campaigns or who may not have easy access to culturally relevant and language-concordant reputable sources. Although access to vaccines remains a significant barrier, vaccine safety confidence is a significant predictor of influenza and COVID vaccination in Hispanic adults. Yet, little is known about how misinformation narratives emerge specifically in relation to Hispanic communities, how they are disseminated, and how they ultimately affect people's decision to get vaccinated.

Social media posts that include personal narratives are more effective at communicating reliable health recommendations, especially those that come from a trusted peer. Therefore, communication strategies that leverage community and interpersonal relationships can prove extremely effective at debunking misinformation about vaccines. Promotores de salud are trusted community members who serve as links between health/social services and a community to improve access to health services and quality of service delivery. Promotores can diffuse and address misinformation in their communities and can be essential to debunk myths, increase trust, and improve health outcomes; they have been at the forefront of addressing disparities in COVID testing and vaccine uptake. Promotores de salud are uniquely positioned as trusted messengers to debunk vaccine misinformation through strategic use of social media and infodemiology principles.

Dime La VerDAD (Verify, Debunk, and Disseminate) is an innovative social media capacity-building program based on theoretical frameworks related to health communication that empowers promotores de salud to debunk vaccine misinformation through the use of personal narratives on social media. To date, there has been no evaluation of whether training promotores de salud to identify and debunk misinformation on social media can improve uptake of accurate scientific information. Dime La VerDAD (Verify, Debunk, and Disseminate) will evaluate how debunking misinformation is perceived on social media, and discern how these can lead to changes in opinions and behavior. The proposed work will use a rigorous stepped wedge design to:

1. Identify and evaluate promotores' use of social media to disseminate vaccine information in the Hispanic community. We will conduct focus groups and key informant interviews with promotores de salud recruited through Illinois Unidos partnerships to verify their peers' information sources about vaccines, vaccine-related misbeliefs, perceptions of vaccine safety, and personal plans to get vaccinated.

2. Engage Promotores de Salud as community champions in an adapted science communication curriculum so they can learn to identify and debunk misinformation. Participants will learn how to make their own infographics to debunk misinformation as well as incorporate their personal narratives into posts. Promotores will also recruit members of their social media circles to participate as subjects to test the effectiveness of their posts.

3. Test effectiveness of personal-narrative posts versus resharing of standardized debunking content shared by promotores de salud to their social networks. Using a stepped-wedge approach, members of promotores' social media circles will be surveyed to measure the reach and effectiveness of various types of social media posts. We hypothesize that community champions will be viewed as trusted messengers within their social circles and that debunking posts with personal narrative using principles from the training program will be disseminated, viewed, and recalled more often as compared to a standard post without personal narrative and lead to increased COVID and influenza vaccination uptake.

This work will test a model of community engagement and empowerment while providing greater knowledge of how credible scientific information can be shared and effect positive changes in opinions and behavior.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Vaccine uptake among promotores' social media followers	Promotores' social media followers' intent to vaccinate against COVID and/or influenza. Members of promotores' social media circles will be surveyed to understand the reach and effectiveness of various types of social media posts. We will measure effectiveness by surveying the social circles of the Promotores six months after the implementation of the curriculum (see recruitment and retention plan), and after the completion of the campaign. Specific items will include which posts the social circle members remembered most and why. We will also ask whether this changed their thinking about COVID-19 and/or influenza vaccines and or the specific call to action that was put in the infographic.	Year 2 - Year 4
Primary	Promotores' Social Media Self-Efficacy	Compare promotores confidence with addressing misinformation on social media before and after completing the Dime LaVerDAD science communication curriculum. 15-minute survey to assess their work-related social media communication self-efficacy. The baseline survey will also gather demographics, social determinants of health and baseline usage of Facebook and other social media (e.g., social media apps they use, the number of friends on each social media platform, the frequency of reading from and posting/sharing on each platform), and confidence and preparedness to address misinformation in their communities regarding vaccines (COVID-19 and influenza).	Year 1 - Year 3
Secondary	Learner satisfaction	Learner satisfaction will be measured through post evaluations using Likert items based on satisfaction with the course and willingness to recommend to others.	Year 2 - Year 4
Secondary	Verify vaccine-related beliefs in Hispanic communities in Chicago	Obtained through focus groups of promotores de salud. An interview guide will include questions aimed at verifying their use of social media as an information source about vaccines, vaccine-related misbeliefs, characteristics of information sources they trust, perceptions of vaccine safety, and personal plans to get vaccinated. Questions will be developed based on the Appreciative Inquiry (AI) model which is an asset-based approach to organizational and social engagement that utilizes questions and dialogue to help participants uncover existing strengths, advantages, or opportunities in their communities, organizations, or teams	Year 1-2
Secondary	Social media engagement	We will first use social media data analytics to measure and understand reach in cyberspace. We will ask for each promotor/a's consent and train them how to export their Facebook posts into JSON files that will be shared with the research team. If we need to add another emerging social media platform that does not support direct data export, we will explore different options to retrieve data, such as joining promotores' social circles or group chats, or instruct promotores to self-report data of their social media posts. We will quantify the volume of "impressions" (i.e., the number of users who will see the post) and "buzz" generated by promotores (e.g., numbers of likes, comments or shares). Then text analytics methods will be adopted to analyze more fine-grained reactions to these posts.	Years 1- 5
