Colorectal cancer (CRC) screening in the form of self-sampling enhances participation and early cancer detection. However, CRC screening participation in Sweden is marked by inequality. Moreover, individuals are relatively uninformed about screening procedures, with existing informational channels all exhibiting various limitations. Hence, this project was initiated in collaboration with KI and KTH to develop a digital decision aid for individuals called into CRC screening. This study aims to mark an initial stage of development, with the overarching goal being to improve CRC screening participation rates and support informed decision making aligned with patient values and preferences. Using an approach rooted in the shared decision-making (SDM) model, the study investigates user attitudes and preferences concerning health, digital healthcare services and cancer screening through conducting semi-structured interviews and a thematic analysis. These insights inform user requirements, which are integrated with stakeholder requirements and the current informational landscape to shape the digital decision aid’s information architecture and design. The research identifies various challenges and opportunities for the development of the digital decision aid in a Swedish context, underscoring the importance of adapting the decision aid to user needs and preferences. In subsequent stages of development, the prototype produced by this study should be evaluated through usability testing, and further user research should be conducted to generate more specific user requirements concerning visual and interactional elements. |
