Show abstract
This paper describes eHEALS.com.br, a web-based platform that automates the administration of the Brazilian eHealth Literacy Scale (eHEALS-Br). The system collects responses online, scores users in real time, and provides personalized feedback based on five levels of digital health literacy. A systematic literature review was conducted to map existing instruments and identify gaps related to automation, temporal control, and inclusion. The platform architecture combines a React and TypeScript frontend with a Node.js and MongoDB backend, deployed on a secure virtual private server. In a pilot study with 12 participants, the automated eHEALS-Br scale demon-strated excellent internal consistency (Cronbachs alpha = 0.929), and additional questionnaire dimensions also showed good reliability. The results demonstrate the feasibility of automating eHEALS-Br, supporting both population studies and individualized clinical use, and reinforcing the potential of digital health tools for monitoring and improving health literacy in Brazil.
