Mixed-Method Formative Evaluation and Cultural Adaptation of Digital Health Communication Content and Delivery...

Area of Science:

• Public Health
• Health Communication
• Digital Health

Background:

• Lung cancer screening (LCS) uptake is low, especially in underserved populations.
• Community Health Centers (CHCs) serve vulnerable patient groups.
• Effective digital health communication is crucial for promoting LCS shared decision-making.

Purpose of the Study:

• To report on the formative evaluation and cultural adaptation of patient-facing digital health communication content for LCS.
• To assess content quality, user experience, and delivery methods for diverse patient populations.
• To inform the development of population health tools for LCS promotion in low-resource settings.

Main Methods:

• A mixed-method approach combining cross-sectional surveys (N=79) and usability observations (N=17).
• Messaging study evaluated patient perceptions of content quality in English and Spanish.
• Usability assessment used think-aloud protocols to identify technical and delivery challenges.

Main Results:

• Patients generally rated content favorably, with similar evaluations in English and Spanish.
• Usability testing identified issues with choice overload and message sequencing.
• Cultural adaptation revealed needs for conversational language, cost transparency, and addressing access anxiety. Trust was fostered by CHC branding.

Conclusions:

• Mixed-method evaluation and cultural adaptation are vital for developing effective digital health tools.
• Addressing technical gaps and community-specific concerns can improve LCS promotion in low-resource settings.
• Tailored digital communication strategies enhance shared decision-making for lung cancer screening.
