THRIVE-Belize is a school-based program being developed to support the health and well-being of adolescents in the Toledo District of southern Belize. The program covers seven topics: communication and emotional regulation, healthy expressions of masculinity, sexual and reproductive health, healthy relationships, mental and physical health, substance use prevention, and environmental health.
Before testing whether the program works, the research team needs to learn whether students, teachers, parents, school staff, and community members find it acceptable, appropriate, and practical to deliver at Toledo Community College. This study (Phase I) does not deliver the program to anyone. Instead, it gathers feedback through surveys, focus groups, and interviews with about 280 participants across these five groups.
The information collected will be used to refine the program and decide whether to move forward to a future pilot study. No medical or educational intervention is given to participants in this phase.
967 studies on the registry are indexed under Health Behavior; 165 are open to participants now.
This study's planned enrollment of 280 is above the median of 219 across 131 observational studies indexed under Health Behavior.

Plan to share: No — No public release of individual participant data (IPD) is planned due to the small sample size and potential for re-identification in a single-school setting. De-identified aggregate data may be made available upon reasonable request following primary publication, subject to University of Arizona IRB approval, Belize Ministry of Health and Wellness IRB approval, and a formal data sharing agreement.
