Evaluating User-Centered Design Techniques for Multi-Channel Maternity Care: Card Sorting vs. Interactive Dialogue Modeling

Web-based platforms play an important role in digital service delivery due to their broad accessibility and compatibility. In the context of healthcare, especially maternity care, usability and information design are critical to ensuring effective user engagement and service satisfaction. This paper presents a comparative evaluation of two user-centered design techniques—Card Sorting and Interactive Dialogue Modeling (IDM)—to determine their suitability for designing information-rich, multi-channel digital maternity care systems. We developed a prototype platform that personalizes content and support based on users' health profiles and preferences, aiming to bridge gaps in traditional maternity care, particularly in underserved regions. A user study was conducted to evaluate usability and user satisfaction across both design approaches. The results indicate that IDM outperforms Card Sorting in facilitating intuitive navigation and delivering a more personalized user experience for complex healthcare interfaces.
