Objectives: The aim of the present analysis is to identify the reasons for accepting or rejecting the invitation to be screened by the Faecal Immunochemical Test as part of the free Danish screening programme for colorectal cancer (CRC).
Study design: A cross-sectional representative survey of 15,072 Danish citizens aged 50-80 years was collected in 2019 via a Web-based questionnaire administered by Statistics Denmark. Among the net sample of 6807 respondents (45%), 177 were excluded because of current treatment for colorectal disease.
Methods: To determine the reasons for accepting or refusing the invitation to be screened for CRC, a latent class analysis was conducted, which allowed participants to provide several reasons for acceptance or rejection of screening.
Results: The most important reason for participating in CRC screening was the active public programme. A further reason for participation was the perceived risk for CRC, mainly in combination with the public programme. The reasons for participation did not differ between individuals who had participated and those who intended to participate when offered. Among participants who declined screening, the most frequent reasons were that they forgot to participate or that they were concerned about the unpleasant test procedure. Among individuals who intended to decline screening, a perceived low risk for CRC was the most frequently cited reason.
Conclusions: Recommendation from a general practitioner (GP) was not given as a frequent reason for CRC screening participation which is discussed as a challenge to participation rates in population based screening program The main reasons reported for non-participation in CRC screening (i.e. forgot to participate or the unpleasant test procedure) might be addressed by a stronger endorsement from GPs.
