Development and initial testing of a computer-based patient decision aid to promote colorectal cancer screening for primary care practice.

Background: Although colorectal cancer screening is recommended by major policy-making organizations, rates of screening remain low. Our aim was to develop a patient-directed, computer-based decision aid about colorectal cancer screening and investigate whether it could increase patient interest in screening.

Methods: We used content from evidence-based literature reviews and our previous decision aid research to develop a prototype.
