Introduction Low socioeconomic position is associated with lower health literacy, higher rates of colorectal cancer (CRC) mortality, and lower participation rates in screening programs. The organized CRC screening program of the Canton of Vaud, Switzerland developed a new electronic tool to facilitate access to information to the program and orient low-risk participants towards non-invasive tests. This qualitative study aimed to evaluate the user experience of a beta version of the tool and whether users could identify the actions necessary to participate in the program after using the tool.

Methods Using the ‘think-aloud technique’, semi-structured interviews were conducted assessing the user experience with the Morville Honeycomb framework: useful, desirable, accessible, credible, findable, usable, valuable. Participants’ health literacy was evaluated using the S-TOHFLA test. Interviews were transcribed and analyzed thematically on the software MAXQDA, with 20% dual independent coding. COREQ norms were followed.

Results We performed 9 interviews (mean age 61 years, 78% women, 33% with low health literacy). Participants appreciated the presence of graphics illustrating the content. They had confidence in the information provided although low health literacy users would have preferred directly receiving the information from medical professionals rather than through the website. The most frequently cited difficulties were navigation (understanding the need for scrolling) and text that was sometimes complex to understand (medical terms). In addition, most participants were able to accomplish tasks such as finding out how to retrieve a FIT (fecal immunochemical test) from a pharmacy.

Discussion Through content and software modifications, the collected feedback was directly useful for the website’s development team. The tool needed to be further simplified, which was a challenge given the need for accurate, specific information.

Conclusion The impact of the electronic tool on disparities in program participation will be assessed after implementation.
