Population testing of an internet-based Personalised Decision Support system for Colorectal Cancer screening

Interventions: Participants in the intervention conditions receive ONE of ethier an internet-based tailored decision support intervention, or internet-based non-tailored decision support intervention. In each intervention, participants answer questions concerning their perceived susceptibility to Colorectal cancer (CRC) and attitudes towards CRC screening. Tailored responses are then generated for the ‘tailored group’ which are designed to correct misaprehensions where they exist. For the non-tailored group participants do not receive tailored messages but rather generic information brochures concerning Colorectal cancer. This intervention is accessed once only and participants work through it at their own pace. The overall duration of the study will be approximately 12 months.
Primary outcome(s): Number of participants completing a colorectal cancer screening test per group. All participants receive a free Colorectal Cancer screening test and the number of kits returned per study arm is recorded upon return of the kit[approximately one year after randomisation]
Study Design: Purpose: Prevention; Allocation: Randomised controlled trial
