This study has been completed.
Sponsor:
Collaborator:
California Academy of Family Physicians
Information provided by (Responsible Party):
University of California, Davis

NCT00965965
First received: August 20, 2009
Last updated: April 26, 2012
Last verified: April 2012
  Purpose
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.

Condition Intervention
Colorectal Neoplasms Behavioral: New colorectal cancer screening patient education document Behavioral: Traditional colorectal cancer screening education document

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Investigator, Outcomes Assessor)
Primary Purpose: Health Services Research
Official Title: Effects of Comprehensibility of Colorectal Cancer Screening Educational Materials on Patient Knowledge and Motivation: A Randomized Controlled Trial

Primary Outcome Measures:
  • Comprehension of randomly assigned educational document [ Time Frame: Immediately after receiving randomly assigned study intervention (that same day) ]

Secondary Outcome Measures:
  • Colorectal cancer screening knowledge [ Time Frame: Immediately after receiving randomly assigned study intervention (that same day) ]
  • Self-efficacy for undergoing colorectal cancer screening [ Time Frame: Immediately after receiving randomly assigned study intervention (that same day) ]
  • Perceived barriers to undergoing colorectal cancer screening [ Time Frame: Immediately after receiving randomly assigned study intervention (that same day) ]
  • Readiness to undergo colorectal cancer screening [ Time Frame: Immediately after receiving randomly assigned study intervention (that same day) ]

Enrollment: 60
Study Start Date: August 2009
Study Completion Date: April 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.
