About this study
Official title: Effectiveness of a Structured Health Literacy Education Program on Health Literacy and Self-efficacy in Adolescents: A Randomized Controlled Trial
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Structured Health Literacy Education ProgramBehavioural
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.
| Study group | Role | What they receive |
|---|---|---|
| Health Literacy Education Program | Experimental | Participants received a six-session structured health literacy education program delivered weekly in a school setting. The program focused on improving adolescents' ability to access, understand, evaluate, and apply health-related information and aimed to strengthen self-efficacy skills. Receives: Behavioral: Structured Health Literacy Education Program |
| Control Group | No intervention | Participants did not receive the structured education program during the study period. After study completion, the program was offered to the control group. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Health Literacy Score
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.
Measured: Baseline and immediately after the 6-week intervention.
Secondary outcomes (1)
Self-Efficacy Scale for Children
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.
Measured: Baseline and immediately after 6-week intervention
