- All authors wish to express their gratitude to our participants for their enthusiastic participation in the intervention over a long five-week period. Also, all authors are deeply grateful to The National Research Foundation of Korea (NRF) funded by the Ministry of Science, ICT & Future Planning for their support (Grant No. NRF-2017R1C1B5017768).
The Internet is considered an important channel for providing health information to older adults. We developed an intervention to improve eHealth literacy in older adults according to the information-motivation-behavioral skills (IMB) theory and Intervention Mapping. This study aimed to analyze the effect of a developed intervention on information, motivation, behavioral skills, and behaviors related to eHealth information in older adults.
Forty-six older adults over the age of 65 were recruited from two senior welfare centers in a city in South Korea. We divided the participants into four groups and conducted one intervention per group from March to December 2019. One intervention consisted of 5 sessions and was performed once a week (2h/1 time) for 5 weeks, culminating in a total lecture time of 10h. One lecture instructor and two assistant instructors supported the participants in the computer practices.
Participants computer/web knowledge, perceived ease of use, perceived enjoyment, and attitude toward eHealth information showed statistically significant increases. The eHealth literacy efficacy score, searching performance score, and understanding score were also significantly increased. However, there was no significant difference in perceived usefulness.
The application of the current theory-based methodology can improve the quality of research in eHealth literacy. Additionally, various interventions should be developed and continuously applied to improve eHealth literacy among older adults.
