Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.
