As a secondary goal, the study is interested how various information behaviors, such as people's self-reported seeking of health information and encountering of health information, demographic variables, individual difference variables, and message exposure associate with their intentions to adhere to recommended colorectal cancer screening guidelines from the National Cancer Institute.
