Brief Summary

This randomized controlled study evaluates the effectiveness of a structured health literacy education program designed for ninth-grade adolescents in a public high school. A total of 102 students were stratified by gender and randomly assigned to intervention and control groups. The intervention group received a six-session health literacy education program delivered in the school setting. The program focused on improving adolescents' ability to access, understand, evaluate, and apply health-related information, as well as strengthening self-efficacy skills. Health literacy and self-efficacy were measured before and after the intervention using validated scales. The study aims to determine whether a structured school-based education program can improve adolescents' health knowledge and self-efficacy levels.
