Brief Summary
The goal of this research study is to compare how people who are 45-75 years old respond to 3 different versions of a program about screening tests for colorectal cancer. Researchers want to use this study as part of a long-term project to learn the best ways to communicate health information to patients.

Outcome Measures
Primary Outcomes (1)
Gist and Verbatim Knowledge for a Colorectal Cancer Screening Program
The fixed effects analysis of variance (ANOVA) will utilize a factorial design with two factors: content presentation type (standard, animated, interactive) and numeracy status (high and low based on US population scores). Main dependent measures are gist and verbatim knowledge. Gist and verbatim knowledge scores (0-100) looked at separately as well as combined.
