Trial Information

Tailored Interactive Intervention to Increase CRCS

Specific Aim 1: Identify behavioral, social, and environmental factors associated with CRCS
in male and female patients ages 50 to 64 years old in a primary care practice in Houston,

1.1. Update literature reviews of CRCS adherence. 1.2. Conduct secondary analysis of
relevant data from other projects. 1.3. Conduct focus groups with primary care patients to
determine their knowledge, attitudes, and beliefs about CRCS and to gather data to use for
development of the educational intervention.

Specific Aim 2: Develop a personal computer (PC)-based tailored interactive intervention
based on the transtheoretical (stages of change) model to increase CRCS in accordance with
American Cancer Society (ACS) CRCS guidelines.

Specific Aim 3: Evaluate the effectiveness of the PC-based tailored interactive intervention
for increasing CRCS through a randomized controlled trial.

Specific Aim 4: Analyze the relationship between a number of predictor variables and CRCS
completion in order to develop a more complete conceptual framework for understanding
screening adherence.

Specific Aim 5: Conduct a cost-effectiveness analysis of the PC-based tailored interactive
intervention for increasing CRCS in a primary care setting.

Inclusion Criteria:

- Have had CRC or adenomatous polyps

- Must agree to schedule a routine physical examination with their primary care
provider and to complete a baseline interview

Exclusion Criteria:

-Have never been screened or be due for CRCS according to the ACS guidelines
