What this study is about
The purpose of this study is to determine the cultural, socioeconomic, inter/personal and work-related factors that influence COVID 19 mitigation practices including social distancing, hand-washing and Personal protective equipment (PPE) use, to adapt, implement, and test Vale+Tú Salud in a cluster randomly assigned trial to assess the extent to which LDL report increased adherence with COVID 19 mitigation practices 1 month post intervention and to promote Vale+Tú Salud just-in-time results and increase its capacity to rapidly disseminate findings among groups that serve LDL and other Latino immigrants.

Interventions
BEHAVIORAL
COVID-19 Group Problem Solving
Participants will have three core components to be delivered at the corner by trained data collectors. Interactive dialogue component that incorporates popular education activities aimed at developing social cohesion among LDLs, building awareness about COVID-19 risks and protective behaviors and developing a personal commitment called "Mi Promesa" to implement COVID mitigation practices. Navigation Component will consist of providing information and linking LDLs with social service providers and the "Multiplicador de salud"/Health Multiplier component that builds from the theoretical and practice-based method of mobilizing social networks and social support.
BEHAVIORAL
Standard of Care
Participants will receive a COVID-19 prevention flyer and social resources list only
BEHAVIORAL
Booster session
Participants in this group will also receive a "booster phone call" 10 to 15 days after the small group intervention to provide brief prompts to encourage participants to act on their personal commitments and encourage them to seek community resources.

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.
