Bringing fictional characters to life: reflections on co-creating a comic book with members of the public.

There are growing calls for cancer screening to become more personalised by considering a range of risk factors, rather than a one-size-fits-all, age-based approach. The aim of this public involvement was to co-create a comic book about bowel cancer screening to be used as a visual elicitation tool in research focus groups with members of the public and healthcare professionals, as part of the At Risk study, to discuss their attitudes toward personalised bowel cancer screening, which would involve considering different risk factors. This article critically reflects on the co-creation process to develop the comic book, benefits and challenges, and some lessons learned to inform other researchers considering a similar approach. In total, ten public contributors (5 men and 5 women) from two public involvement networks participated in two successive online workshops to develop six fictional characters, two for each level of bowel cancer risk (low, moderate and high risk). This tool was then used in the At Risk study comprising five focus groups involving 23 participants, including members of the public (n = 12) and healthcare professionals (n = 11). The co-created comic book was a generally well-received research tool able to generate discussion about a complex topic, bowel cancer risk, in an accessible way. It was suggested that the comic book may also be extended beyond the research context to inform bowel cancer screening decisions and raise awareness of risk factors.
