Brief summary
Health literacy is a key determinant of children's health and well-being, enabling them to access, understand, evaluate, and use health information to make informed health-related decisions. Middle childhood represents a critical developmental period for strengthening these competencies; however, evidence regarding theory-based school interventions designed to improve health literacy in this age group remains limited. This cluster randomized controlled trial aims to evaluate the effectiveness of a six-week, theory-based school health literacy program developed for children aged 9-10 years. The intervention was designed by integrating Nutbeam's Health Literacy Model and Piaget's Theory of Cognitive Development and incorporates interactive, child-centered educational strategies, including educational games, storytelling, role-playing, problem-solving activities, and classroom discussions. Third- and fourth-grade students attending public primary schools in Burdur, Türkiye, were randomly assigned at the school level to either the intervention or control group. Health literacy outcomes are assessed using the Health Literacy Survey Questionnaire for Children-Turkish Version (HLS-Child-Q15-TR) before and after the intervention. The findings are expected to provide evidence regarding the effectiveness of theory-based school health literacy interventions and to inform future school health promotion programs.
Detailed description
Health literacy is recognized as a fundamental determinant of lifelong health and well-being. Childhood represents a critical period for the development of health literacy competencies because children begin to acquire the cognitive, social, and behavioral skills necessary to access, understand, evaluate, and apply health information in everyday life. Despite growing international interest in promoting health literacy among children, evidence regarding theoretically informed school-based interventions remains limited. This study evaluates a theory-based school health literacy intervention developed for primary school children aged 9-10 years. The intervention was designed by integrating Nutbeam's Health Literacy Model, which conceptualizes health literacy as functional, interactive, and critical competencies, with Piaget's Theory of Cognitive Development, emphasizing learning strategies appropriate for children in the concrete operational stage. The program incorporates child-centered educational approaches, including educational games, storytelling, role-playing, problem-solving activities, visual materials, classroom discussions, and real-life scenarios to facilitate active learning and the application of health information. The intervention consists of six weekly classroom sessions delivered over a six-week period. The effectiveness of the program is evaluated using a cluster randomized controlled trial conducted in public primary schools in Burdur, Türkiye. Health literacy is assessed before and after the intervention using the Health Literacy Survey Questionnaire for Children-Turkish Version (HLS-Child-Q15-TR). The findings are expected to contribute to the evidence base for theory-based school health literacy interventions and support the development of effective school health promotion programs for children.
Interventions
BEHAVIORALTheory-Based School Health Literacy Program
A six-week classroom-based educational intervention designed to improve health literacy among children aged 9-10 years. The program was developed based on Nutbeam's Health Literacy Model and Piaget's Theory of Cognitive Development and consisted of six weekly 40-minute sessions using educational games, storytelling, role-playing, problem-solving activities, classroom discussions, visual materials, and real-life scenarios to strengthen functional, interactive, and critical health literacy.

Masking description
Blinding was not feasible because the educational intervention was delivered directly to students in the classroom by the principal investigator. Consequently, participants, investigators, and outcome assessors were aware of group allocation.
Intervention model description
Public primary schools were randomized at the school (cluster) level to either the intervention or control group. Third- and fourth-grade classrooms were randomly selected within each school. Students in the intervention group received a six-week theory-based school health literacy program, while those in the control group continued with the standard school curriculum during the study period. Outcome assessments were conducted at baseline and immediately after completion of the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Health literacy | Baseline and one week after completion of the 6-week intervention | Children's health literacy will be assessed using the Turkish version of the Health Literacy Survey Questionnaire for Children (HLS-Child-Q15-TR). The scale consists of 15 items across three domains: health care, disease prevention, and health promotion. Items are rated on a 4-point Likert scale from 1 to 4, with higher scores indicating greater difficulty in dealing with health-related information. Scores may be transformed so that higher transformed scores indicate higher health literacy, depending on the scoring procedure used. |
