Thailand's Health Literacy Movement: A Comprehensive Summary The development of health literacy (HL) in Thailand since 2015 is driven by two primary mechanisms: a Top-Down approach through national reform and long-term strategic plans, and a Bottom-Up approach involving collaboration between the government and private sectors . 1. Top-Down: Policy and Strategic Integration Between 2015 and 2017, the Thai government established health literacy as a national agenda . This movement was institutionalized by integrating HL into the 20-Year National Strategy and the 12th and 13th National Economic and Social Development Plans . The primary goal is to improve health outcomes across four key settings: healthcare facilities, educational institutions, workplaces, and communities . Key performance indicators include increasing the percentage of citizens with sufficient HL, promoting desirable health behaviors, and reducing healthcare costs and disinformation . 2. Bottom-Up: Professional Networks and Associations A significant milestone in the bottom-up movement was the 2018 establishment of the Thai Health Literacy Association (THLA) . The THLA serves as a hub for knowledge exchange, research, and innovation, bridging the gap between policy and practice . It provides guidance to both public and private sectors to transform Thai society into a Health Literate Society (HLS) . Furthermore, Thailand actively participates in international networks like the Asian Health Literacy Association (AHLA) to exchange global best practices . 3. The Thai Health Literacy Frameworks Thailand adapted international HL models to fit its specific social context. The V-Shape Process: This model outlines the citizen's journey: Access information, Understand it, Inquire for decision-making, Apply/Change behavior, and finally, Tell others . The Cubic Model: A 3D matrix that integrates the HL process with the continuum of care (healthcare, prevention, promotion, and product selection) and the Life Course Approach (mothers/children, youth, working age, and the elderly) . The 66 Key Messages: Inspired by international standards, these messages provide a core health knowledge base for all age groups in Thailand . 4. Measurement and National Progress To monitor progress, Thailand developed localized survey tools, transitioning from the comprehensive HLS-TH-Q87 to more concise versions like the HLS-TH-Q17 for national surveys . National surveys conducted in 2019 and 2023 showed that approximately 80.9% of the Thai population possesses sufficient health literacy . 5. Transition to Organizational Health Literacy (OHL) The movement has evolved from focusing solely on individual skills to emphasizing Organizational Health Literacy (OHL) . Recognizing that healthcare systems are often too complex, the goal is to create Health Literate Organizations (HLOs) that are easy to navigate and understand . This is supported by the "Satharanasook Unjai" app, an online tool used for the registration, self-assessment, and certification of HLOs across the four key settings . 6. Future Directions (2023–2027) Under the 13th National Plan, the focus is expanding into specialized domains, including Mental Health Literacy, Rational Drug Use Literacy (RDU), and Media Literacy . The government continues to scale up HLOs, with over 14,000 organizations currently registered in the national system
