This is a cluster randomized controlled trial with two assessment points (baseline and 24-week follow-up) comparing the Claudia Carraro prevention program to a no-intervention control group. The intervention group was also assessed at post-intervention. To ensure that all students benefit from the intervention, the control group received the intervention after the 24 weeks. Randomization was performed at the school level, not the student level.
