Effectiveness of Intensive Tutoring vs. Flexible Self-Learning on Digital Health Literacy and Self-Efficacy for "My Health Bank" App Use Among Adults Over 50
Effectiveness of Intensive Tutoring vs. Flexible Self-Learning on Digital Health Literacy and Self-Efficacy for "My Health Bank" App Use Among Adults Over 50: A Randomized Controlled Trial Using AI-Co-Created Materials
Tri-Service General Hospital
235 participants

INTERVENTIONAL
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.
Eligibility
Inclusion Criteria4
- Participants aged 50 years and older.
- Possession of a smartphone with basic operational skills (e.g., unlocking the phone, making calls, and using LINE).
- Self-reported lack of familiarity with the "My Health Bank" App (used less than 3 times or never used in the past year).
- Proficiency in listening, speaking, reading, and understanding Mandarin Chinese.
Exclusion Criteria4
- Regular users of the "My Health Bank" App (used 3 times or more in the past year).
- Severe cognitive impairment identified through brief cognitive screening, the participant unable to follow instructions or complete questionnaires.
- Smartphone operating system is too outdated to support the installation of the "NHI App" (National Health Insurance App).
- Inability to complete the App download and installation process independently or with family assistance (e.g., lost App Store/Google Play password, insufficient storage space).

Interventions
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.
