This study aimed to investigate the personal characteristics and online usage behavior of older adults, assess their level of acceptance of such services, and analyze the key factors influencing the adoption of Thailand Post Company’s online ordering system. A structured questionnaire was administered to 400 residents aged 60 and above in Nonthaburi Province, Thailand, and supplemented with qualitative insights. The instrument was validated through expert review and pilot testing, achieving a Cronbach’s alpha coefficient of 0.95. Data were analyzed using descriptive statistics, t-tests, ANOVA, correlation analysis, and multiple regression analysis. The findings revealed that most participants were female, had at least secondary education, and possessed sufficient income to shop online. Ease of use and system security emerged as critical determinants of service usage, while both attitude toward usage and ease of use significantly influenced acceptance of Thailand Post’s online services. These results underscore the importance of designing online platforms that prioritize simplicity, security, and the specific needs of older adults. The findings provide practical implications for improving digital service delivery in the health sector and inform future policy and research on technology adoption among aging populations.</p>2025-12-30T00:00:00+07:00Copyright (c) 2025 CHIANG MAI UNIVERSITY JOURNAL OF ECONOMICS
