Information-seeking in cancer survivors: application of the Comprehensive Model of Information Seeking to HINTS 2007 data.

Despite health care providers' best efforts, many cancer survivors have unmet informational and support needs. As a result, cancer survivors often have to meet these needs themselves, and how they approach this process is poorly understood. The authors aimed to validate and extend the Comprehensive Model of Information Seeking to examine information-seeking behaviors across a variety of channels of information delivery and to explore the impact of health-related factors on levels of information seeking. The data of 459 cancer survivors were drawn from the National Cancer Institute's 2007 Health Information National Trends Survey. Structural equation modeling was used to evaluate the associations among health-related factors, information-carrier factors, and information-seeking behavior. Results confirmed direct effects of direct experience, salience, and information-carrier characteristics on information-carrier utility. However, the direct impact of demographics and beliefs on information-carrier utility was not confirmed, nor were the effects of information-carrier factors on information-seeking behavior. Contrary to expectations, salience had direct effect on information-seeking behavior and on information-carrier characteristics. These results show that understanding antecedents of information seeking will inform the development and implementation of systems of care that will help providers better meet cancer survivors' needs.
