1) Engagement & Relevance Challenge: Building trust around mental health remained a significant barrier due to stigma and cultural norms. Many young people hesitated to seek care given high levels of stigma in a post-genocide context; 2) Accessibility Challenge: Limited internet access and device availability meant that solely digital solutions were not viable. 3) Usability Challenge, Low Digital & Mental Health Literacy : The target population had low levels of digital and mental health literacy as well as limited reading/writing skills.

1) Co-Design with Young People Improves Engagement & Relevance: Engaging youth in the design, testing, and implementation of TEH ensured that the platform was culturally relevant, youth-friendly, and responsive to their needs. For example, TEH addressed the misconception that poor mental health is not real unless visible by incorporating content on early signs and symptoms of mental health conditions; 2) Using Diverse Delivery Channels Enhances Accessibility Challenge: TEH had to combine online content (Bohoka) with offline methods (Turi Kumwe workshops, printed flyers, and in-person facilitation) to ensure accessibility for all users. A dual approach (digital & in-person) increased accessibility for youth in low-connectivity settings. Tablets were strategically placed in youth centers, and peer facilitators (Wellness Warriors) delivered workshops using both online and offline materials, ensuring that mental health education reached youth despite digital barriers; 3) Designing for Low Digital & Mental Health Literacy Increases Usability Challenge: TEH was designed with minimal text inputs, pre-generated prompts, and visual content, making it easy to use even for those with low literacy levels. All content was translated into Kinyarwanda by native speakers to ensure cultural and linguistic accuracy.
