title: Predictors of perceived ambiguity about cancer prevention recommendations: sociodemographic factors and mass media exposures.
abstract: Cancer prevention recommendations reaching the public today are often ambiguous-that is, of uncertain reliability, credibility, or adequacy-yet little is known about the factors that influence public perceptions of this ambiguity. We used data from the 2005 Health Information National Trends Survey, conducted by the U.S. National Cancer Institute, to explore how sociodemographic characteristics and self-reported mass media exposures relate to perceptions of ambiguity regarding recommendations for the prevention of colon, skin, and lung cancer. Various sociodemographic characteristics (age, education, race) and mass media exposures (television, radio, Internet, health news) were found to be associated with perceived ambiguity about cancer prevention recommendations, and many of these associations varied by cancer type. These findings have important implications for future health communication research and practice.
