Background: The promotion of mobile health (mHealth) and eHealth technologies as tools for managing chronic diseases,
particularly diabetes mellitus, is on the rise. Nevertheless, individuals with diabetes frequently face a literacy gap that hinders
their ability to fully leverage the benefits offered by these resources. Enhancing technology literacy to facilitate the adoption of
mobile eHealth services poses a significant challenge in numerous countries.
Objective: This study aims to develop an educational mobile eHealth literacy (eHL) program for patients with diabetes and to
evaluate its effect on patients’ outcomes.
Methods: This study designed a mobile eHL education program comprising 2 modules specifically tailored for individuals with
type 2 diabetes (T2D). These modules focused on guiding participants through the process of effectively navigating reliable health
websites and utilizing diabetes-related apps. Using a pre- and posttest experimental design, the study featured an intervention
group and a control group. Participants were recruited from 3 outpatient departments in hospitals, and assessments were conducted
both before and after the intervention, along with a follow-up measure at the 3-month mark. The evaluation encompassed
sociodemographic characteristics, computer and internet proficiency, mobile app usage, mobile eHL, and patient outcomes such
as self-care behaviors and glycated hemoglobin (HbA1c) levels.
Results: The analysis included a total of 132 eligible participants. Significant differences were observed in the mean scores of
