This research redefines digital health literacy for an AI-driven world, emphasizing the alignment between users and technology. Using a Delphi method, it identifies three core components—knowledge, skills, and context. The resulting framework guides the design of digital health tools that better support behavior change by adapting to users’ real-world needs.

This research creates a core outcome set for clinical trials of physical activity in older adults. Because trials currently measure inconsistent outcomes, evidence cannot be easily combined. Using a multi-round expert and stakeholder survey, the project will establish essential outcomes to reduce research waste, improve knowledge synthesis, and strengthen healthcare decisions.
