Effectiveness of a Structured Health Literacy Education Program on Health Literacy and Self-efficacy in Adolescents

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.

Treatment and study plan

Structured Health Literacy Education Program

Behavioral

A six-session school-based education program designed to improve adolescents' health literacy and self-efficacy. The program included interactive sessions focusing on accessing, understanding, evaluating, and applying health-related information.

Primary outcomes

  1. Health Literacy Score

    Time frame: Baseline and immediately after the 6-week intervention.

    Health literacy will be measured using the Health Literacy Scale for School-Aged Children (HLSAC) developed by Paakkari et al. The scale consists of 10 items scored on a 4-point Likert scale, with total scores ranging from 10 to 40. Higher scores indicate higher levels of health literacy.

Secondary outcomes

  1. Self-Efficacy Scale for Children

    Time frame: Baseline and immediately after 6-week intervention

    Self-efficacy will be assessed using the Self-Efficacy Scale for Children developed by Muris. The scale includes 21 items rated on a 5-point Likert scale, with total scores ranging from 21 to 105. Higher scores indicate higher levels of self-efficacy.
