Abstract
This intervention involves the delivery of SMS and WhatsApp messages summarizing the study results to participants. The concise messages express gratitude for participants' involvement, announce the completion of the evaluation, and provide a brief overview of the results. SMS messages include URLs for participants to access more detailed information in Spanish. WhatsApp messages include an introduction to the results and an image summarizing key findings, integrating both quantitative data and qualitative quotes from program recipients. The insights derived from this project aim to enrich our understanding of participant perspectives, program impact, and the broader evaluation process.

Experimental Design

Experimental Design
A sample of 1532 program participants from the evaluation study sample will be randomly assigned to the treatment or control group with a probability of 50%, respectively, resulting in 766 treatment and 766 control participants.
Experimental Design Details
Randomization Method
The randomization protocol will be as follows:
- Participant unique IDs will be ordered randomly. No participant names or other PIID will be used during the assignment.
- Participants will be stratified by nationality.
- Using the randtreat command from Stata, participants will be randomly assigned treatment or control status considering the strata that were previously defined.
- In the case of misfits, this will be assigned considering the global balance of the assignment. This is done automatically by the randtreat command.
To ensure that the randomization was properly executed, we analyzed baseline covariates and outcomes from the first study to check for balance between treatment and controls group. These results can be seen in the following tables.
