Brief Summary
Dime la Verdad (Tell me the truth) will evaluate the use of storytelling by community health workers as a communication strategy to disseminate reliable health information on social media and encourage informed decision-making in favor of recommended immunizations in communities with high morbidity and mortality due to respiratory virus infections. Dime La Verdad is an innovative social media capacity-building program based on theoretical frameworks related to health communication that empowers community health workers to disseminate reliable information about respiratory virus protection strategies through the use of personal narratives on social media. The proposed work will use a rigorous stepped wedge design to 1) deliver a scalable program of science communicators using an adapted curriculum grounded in principles of health communication, 2) evaluate how diffusion of health messaging is perceived on social media, and 3) discern how use of personal narratives to enhance science communication can encourage informed decision-making to promote evidence-based immunization practices and improve health outcomes.

Outcome Measures
Primary Outcomes (2)
Uptake of respiratory virus protection strategies among Community health workers' social media followers
Community health workers social media followers' intent to use respiratory virus protection strategies. Members of community health workers' social media circles will be surveyed to understand the reach and effectiveness of various types of social media posts. Investigators will measure effectiveness by surveying the social circles of the community health workers 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. Investigators will also ask whether this changed their thinking about respiratory virus protection strategies and or the specific call to action that was put in the infographic.
Year 2 - Year 4
Community health workers Social Media Self-Efficacy
Compare Community health workers confidence with disseminating reliable information on social media before and after completing the 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 disseminate reliable information in their communities regarding about respiratory virus protection strategies
Year 1 - Year 3

Experimental: Cohort 1 participation in science communication curriculum
EXPERIMENTALCommunity health workers servicing two geographically adjacent community areas out of the seven selected for participation in this study will receive a tailored curriculum where they can learn to diffuse reliable information and create infographics and media as well as incorporate their personal narratives into social media posts for their communities. The core of the implementation strategy consists of augmenting training and self-efficacy for natural community champions as trusted messengers to diffuse reliable information.

The core of the implementation strategy consists of augmenting training and self-efficacy for natural community champions as trusted messengers to diffuse reliable information.
Experimental: Cohort 3 participation in science communication curriculum
EXPERIMENTALCommunity health workers servicing three geographically adjacent community areas out of the seven selected for participation in this study will receive a tailored curriculum where they can learn to diffuse reliable information and create infographics and media as well as incorporate their personal narratives into social media posts for their communities. The core of the implementation strategy consists of augmenting training and self-efficacy for natural community champions as trusted messengers to diffuse reliable information.
Experimental: Cohort 4 participation in science communication curriculum
EXPERIMENTALCommunity health workers servicing one community area out of the seven selected for participation in this study will receive a tailored curriculum where they can learn to diffuse reliable information and create infographics and media as well as incorporate their personal narratives into social media posts for their communities. The core of the implementation strategy consists of augmenting training and self-efficacy for natural community champions as trusted messengers to diffuse reliable information.
