Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Health Services Research
    • Masking: Double (Investigator, Outcomes Assessor)
  • Study Primary Completion Date: April 2010

Interventions

  • Behavioral: New colorectal cancer screening patient education document
    • The newly developed educational document was created accounting for health behavioral models (such as the Expanded Health Behavior Model, Social Cognitive Theory, and the Transtheoretical Model) and related research studies indicating the factors that most strongly and positively influence patients’ cognitions regarding colorectal cancer screening and are, in turn, predictive of actual colorectal cancer screening behavior.
  • Behavioral: Traditional colorectal cancer screening education document
    • The traditional educational document is a slightly edited version of materials freely available on the National Cancer Institute (NCI) web site, used in this study with the permission of the NCI.

Arms, Groups and Cohorts

  • Experimental: Experimental patient education document
  • Active Comparator: Traditional patient education document
