OVERVIEW OF FIVE WIDELY APPLIED THEORETICAL MODELS IN PUBLIC HEALTH
Keywords:
health belief, self-efficacy, social support, chronic care, socio-ecological modelAbstract
This study provides an overview of five widely applied models and theories in public health, including the Health Belief Model, Self-Efficacy Theory, Social Support Theory, Chronic Care Model, and Socio-Ecological Model. Each model is presented in terms of its origin, core components, scope of application, strengths and limitations, and the interactions among them within public health practice. The article proposes an integrated multi-level framework that combines individual, social, systemic, and policy factors to enhance the effectiveness and sustainability of health research and interventions. Coordinated application of these models across different levels not only facilitates a comprehensive understanding of health behaviors but also improves the practicality and effectiveness of healthcare, disease prevention, and management programs, thereby contributing to better public health outcomes
