Colorectal Cancer Screening Intervention for Family Members of Colorectal Cancer Patients

OBJECTIVES:

• Compare the impact of 3 interventions (generic educational print intervention, tailored educational print intervention, or tailored educational print intervention plus telephone counseling) on colorectal cancer screening behaviors and intentions among siblings at increased familial risk for colorectal cancer.

Secondary

• Determine whether demographic factors, medical access, physician recommendation at baseline, and proband (patient) characteristics (e.g., stage of disease) moderate the impact of the interventions on colorectal screening.
• Evaluate whether knowledge, attitude, and physician recommendation variables mediate the association between the interventions and colorectal screening, and determine whether these variables are impacted by the interventions.
• Analyze the cost of each intervention.

OUTLINE: This is a randomized, controlled, cohort, multicenter study. Participants are stratified according to study site. Participants are randomized to 1 of 3 intervention arms.
