Abstract
Although, Thailand has been committed to fight against irrational use of antibiotics since 2007, an inappropriate use of antibiotic continues to occur among Thai population. Therefore, the situation poses a significant challenge to the efficient working of the national rational antibiotic program in Thailand. The objective of this research was to examine the relationship between eHealth literacy, information seeking, knowledge, attitude and self-management of upper-respiratory infection (URI) in Thai population. The quantitative approach was employed in this study. The self-administered questionnaires were distributed to 2,708 respondents who resided in 21 provinces across four regions of Thailand. The results demonstrated that respondents reported low level of eHealth literacy on the ability to evaluate the health information on the internet. Respondents were more likely to seek information regarding the treatment of upper-respiratory infection from member of the family. The overall level of knowledge on antibiotic was moderate. Respondents had a positive attitude toward antibiotic usage and reported a low level of self-management of upper-respiratory infection. Findings of this study offer useful insights into the communication program for the reduction in antibiotic usage for upper-respiratory infection among Thai population.
