Bridging Context and Culture: Designing Cross-Cultural Solutions for Type 2 Diabetes Care in Nigeria

Culturally sensitive design is crucial for developing inclusive technologies, particularly in resource-constrained settings. However, such approaches often oversimplify culture and face challenges in cross-cultural transferability. This study addresses these issues by exploring how participatory design can be both culturally grounded and adaptable across subcultures within African communities. We conducted 13 distributed design workshops with 19 participants, including people with Type 2 Diabetes (T2D), caregivers, and pharmacists, from diverse ethnic groups in Port Harcourt, Nigeria. These workshops informed the design of a mobile health prototype featuring interactive flows in Pidgin English, collaborative care tools, peer support groups, and a calorie prediction feature. The prototype was evaluated by 30 participants through think-aloud sessions and interviews. Findings highlight that while some features aligned with local cultural norms, others were less effective across sociocultural boundaries, even within the same city. We offer insights and methodological guidance for developing digital health tools that are locally relevant and regionally adaptable.
