Abstract
The Health Belief Model (HBM) has been a robust model utilized in predicting individuals’ cancer screening behaviors. However, there is little research regarding the specific impact of communication factors on colorectal cancer (CRC) screening. Building on the HBM, this study investigated how communication factors influence CRC screening. Analyzing data from a sample of the 2005 Health Information National Trend Survey (HINTS), we found that media use for health information and interpersonal health communication had direct effects on both perceived CRC threat and positive expectations for CRC screening; with no direct effect on participation in CRC screening. In addition, interpersonal health communication, new media use for health information, perceived CRC threat, and positive expectations for CRC screening mediated the effects of mass media use for health information on CRC screening.
