Background
The incidence of colorectal cancer (CRC) is increasing globally. The risk of developing CRC in
people with family history (PFH) is at least doubled compared with the average-risk population, yet
the screening uptake in PFH remains low. Several interventions have been tested to promote CRC
screening for PFH. However, a review that systematically maps the evidence of those interventions
is lacking.
Aim
A scoping review was conducted on literature related to interventions that promote CRC screening
in PFH of CRC. We aimed to identify the types of interventions, the development process, their
effectiveness and the factors associated with the outcome.
Method
The Joanna Briggs Institute methodology for scoping reviews was followed. Six databases were
searched for relevant articles in May 2022. Three researchers independently conducted the screening
and data extraction. There was no restriction in language and publication date.
Outcomes
From 9279 records retrieved, 24 studies were included. The studies were published between 1995
and 2020 in 11 countries. There was wide variability across studies: the study population, screening
modalities and measurement of screening outcomes. Theoretical frameworks served as a guide in
intervention development in nine studies, of which seven used the Health Belief Model. Ten studies
reported statistically significant outcomes in increasing screening uptake among PFH of CRC; all
interventions used telephones as part of the intervention, either to elicit background information
to tailor intervention or to provide counselling. Five of the effective interventions involved doctor
consultations and four used motivational interviewing (MI) for counselling.
Conclusion
Future development of interventions to promote CRC screening targeting PFH of CRC may consider
incorporating doctor involvement and counselling using an MI approach. Remote intervention via
telephone may enhance PFH’s accessibility to counselling, which will lead to an improvement in CRC
screening uptake.
