Comprehensibility of Colorectal Cancer Screening Educational Materials: Effects on Patient Knowledge and Motivation

Study Overview
=================
Brief Summary
-----------------
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.

Design Details

Primary Purpose: Health Services Research
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental patient education document<br> | Behavioral: New colorectal cancer screening patient education document<br>* 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.<br>|
| Active Comparator: Traditional patient education document<br> | Behavioral: Traditional colorectal cancer screening education document<br>* 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.<br>|
