The World Health Organization stresses eHealth literacy's importance for effective health management, particularly among older adults, whose eHealth literacy is globally low and unequal. This scoping review aims to identify strategies to enhance their eHealth literacy. A literature search was performed in eight electronic databases until February 20, 2024, found 1629 records, with 24 meeting inclusion criteria. Most studies (8 of 17, 47.1 %) employed health behavior and learning theories. Interventions materials commonly utilized existing or self-designed websites or applications, with some U.S. studies incorporating standardized training materials. Outcome measures included information, psychological motivation, and behavioral change. The eHealth literacy scale was frequently used to assess eHealth literacy. Coach education combined with classroom exercises proved effective, and online health education was pivotal during the COVID-19 pandemic. Future research should focus on enhancing study design, utilizing comprehensive but concise assessment tools, tailoring interventions to theoretical frameworks, and prioritizing privacy and security.
