چکیده (انگلیسی):

Health literacy rates among American and European adults remain low, with almost half of adults having only basic levels in 2012. In this digital era, the Internet has been recognized as an important medium for improving health literacy. However, little is known about the mechanisms that underlie its impact on health literacy. With a general basis in the Cognitive Mediation Model, this study empirically tested a model that included motivation for health-related Internet use, health-related Internet use, perceived health information overload, and health literacy. Structural equation modeling was used to analyze the US-based Health Information National Trends Survey (HINTS) 2013 dataset. The results support for all the paths in our posited model. The effects of motivation for health-related Internet use on health literacy were completely mediated by health-related Internet use and perceived health information overload. The findings extend the Cognitive Mediation Model to the context of health literacy and provide significant implications for the design and dissemination of online health information. Recommendations are made for future research, including further validation of the five-item scale of health literacy.
