View original scientific description
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
