Brief summary

Improved participation in screening for bowel cancer is desirable. Currently population scale bowel cancer screening program delivery is by mailed offer from a central screening service and invitations include a faecal occult blood detection kit. Invitees may decline the offer because they do not feel they are at risk, or because they do not engage with the program. We have developed invitation letters to that include either improved risk messages or messages from previous screening participants in order to overcome these barriers. We will randomly select invitees from the electoral roll and compare population screening participation between groups with or without the preliminary letter to determine which program results in the greater participation rate. Improved participation in screening will ultimately reduce deaths from bowel cancer

Interventions

Intervention 1: the use of a bowel cancer screening invitation letter to that contains photographs of 2 previous screenees who were diagnosed with early bowel cancer through their participation in a bowel cancer screening program, and with simple program advocacy statements from them. Intervention 2: the use of a bowel cancer screening invitation letter that contains enhanced positive framing and generalised risk messages.
