Summary

The purpose of this study is to evaluate the effectiveness of two different educational models in improving the use of the "My Health Bank" App (a Personal Health Record system in Taiwan) among adults aged 50 and older. As Taiwan's population ages, digital health management has become essential, yet older adults often face a "digital divide." Participants will be randomly assigned to either a "Intensive Guided Learning group" (receiving one-on-one human instruction) or a "Flexible Self-study group" (using self-learning materials co-created with Generative AI). The study aims to compare the outcomes of these two groups in terms of enhancing digital health literacy, self-efficacy, and actual App usage behavior to identify more effective and scalable digital health education strategies.

Detailed description

This study is conducted over a period of 18 months (from March 1, 2026, to August 31, 2027) and is divided into three strategic phases: Phase 1 (Months 1-6): Focuses on the development of AI-collaborative educational materials, expert validity review, and a questionnaire pre-test (n=15). A Pilot Randomized Controlled Trial (Pilot RCT, n=60) will be executed to verify the feasibility and readability of the intervention materials. Phase 2 (Months 7-15): The formal enrollment and intervention phase. A full-scale Randomized Controlled Trial (Full-scale RCT, n=160) will be conducted using a single-blind, two-arm design. Participants will be randomly assigned to either the "Intensive Guided Learning group" or the "Flexible Self-study group," with longitudinal data collection and tracking at three time points. Phase 3 (Months 16-18): Data processing, advanced statistical analysis (including SEM to verify empowerment mechanisms), and final manuscript preparation. The study aims to provide empirical evidence for scalable digital health education strategies to reduce the "digital divide" among adults over 50.

Interventions

Type	Name	Description
BEHAVIORAL	AI-Collaborative eHealth Education	This behavioral intervention consists of a structured eHealth literacy curriculum using AI-collaborative educational materials. The program focuses on teaching participants how to utilize the "My Health Bank" platform for personal health management. The intervention is delivered in two formats depending on group assignment: The experimental group receives intensive instructor-led guidance and hands-on practice. The control group engages in flexible self-study using the same AI-generated materials. The curriculum aims to enhance digital health literacy, self-efficacy, and active engagement (measured by frequency of use) with digital health tools among older adults.
