April 26, 2012 updated by: University of California, Davis

Effects of Comprehensibility of Colorectal Cancer Screening Educational Materials on Patient Knowledge and Motivation: A Randomized Controlled Trial

The purpose of this study is to determine whether a newly developed patient education document concerning colorectal cancer screening will be better understood and have greater effects on patient knowledge of and motivation for screening than a standard educational document.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Experimental patient education document
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.
ACTIVE_COMPARATOR: Traditional patient education document
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.
