The goal of this clinical trial is to find out which approach works better in gettingmore of the friends and connections of Latino adults get vaccinated against COVID-19.The main questions this study aims to answer are: 1. Can teaching people to use motivational interviewing help more friends and connections of Latino adults get the COVID-19 vaccine compared to just giving information about the vaccine? 2. What are the things that make it easier or harder for Latinos and networks to get the COVID-19 vaccine? 3. How does this intervention work in practice so that it can be made available to more people in the futureThe researchers will compare the vaccine rates of the friends and connections of Latinoswho have been trained in motivational interviewing with those who have only been giveninformation about the COVID-19 vaccine. This will help figure out which method works bestto encourage more people to get vaccinated.
This study will test the efficacy of an intervention REDES ("Networks") - a social
network intervention - to address COVID-19 vaccine hesitancy and uptake among a cohort of
Latinos and networks. 300 index participants who have taken the COVID-19 vaccine will be
recruited. Half of the index participants (n=150) will be randomized to the experimental
group and will receive training on motivational interviewing to promote vaccine
acceptance and uptake with networks. Index participants in the control group (n=150) will
receive updated information about the COVID-19 vaccine. In addition, unvaccinated primary
and secondary network members of indexes will be recruited for study participation and
COVID-19 vaccination. All participants will be followed prospectively at 6, 12, and 18
months after baseline intake. The specific aims are: 1) Evaluate the efficacy of the
REDES intervention to promote COVID-19 vaccine uptake among Latinos; 2) Examine ongoing
barriers and facilitators of vaccine uptake among Latinos and networks to tailor the
intervention and address new challenges, and 3) Evaluate the implementation determinants
and outcomes of REDES to inform future broad-scale implementation.
Behavioral: REDES
Training on motivational interviewing (MI) led by community health workers on how to use
MI to address vaccine hesitancy using a guiding approach, open-ended questions,
affirmations, reflections, and summaries.
Behavioral: Control
Brief CHW-led training about the safety and efficacy of the COVID-19 vaccine.
Participants will have the opportunity to ask clarifying questions from the CHWs during
the training.
