Introduction: The communication quality of web resources for patients is unknown. The purpose of this study was to assess prostate cancer websites using the Communication AssessmenT Checklist in Health (CATCH). Methods: CATCH is a theory-based tool consisting of 50 elements nested in 12 concepts. Two raters independently applied it to 35 HON certified websites containing information on prostate cancer treatment. Results: Websites contained a mean 24.1 (SD= 3.6) CATCH items. The concepts Language, Readability, Layout, Typography and Appearance were present in over 80% of sites. Content, Risk Communication, Usefulness, and Scientific Value were present in 50% or less. Discussion: The prostate cancer websites evaluated in this study did not present treatment information in a useful, informative or credible way for patients. The communication quality of these resources could be improved with a clear strategic intent focused on decision-making, using CATCH as a guiding framework.
With CATCH it is possible to categorize and understand the mechanisms that can trigger a change in behavior in health care providers. Additional research is needed to validate CATCH before it can be recommended for use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
