Theory-Based School Program to Improve Health Literacy Among Primary School Children (HEALTH-KIDS)

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.
