Online Health Information Seeking and Health Outcomes: The Mediating Role of Health Literacy

Abstract

The rapid expansion of the internet and digital health technologies has fundamentally changed how individuals access, evaluate, and use health information. Online health information seeking has become an important component of contemporary health behavior because individuals increasingly search websites, social media platforms, online forums, health applications, electronic health portals, and search engines for information about diseases, symptoms, treatments, medications, prevention, nutrition, and healthy lifestyles. Although access to online health information can improve knowledge and support informed health decisions, the benefits of online information seeking depend substantially on individuals' ability to locate, understand, critically evaluate, and apply health information. Health literacy therefore represents an important mechanism through which online health information seeking may influence health outcomes. This study examines the relationship between online health information seeking and health outcomes and investigates the mediating role of health literacy. Online health information seeking is conceptualized as the frequency, purpose, and extent to which individuals use digital resources to obtain health related information. Health literacy represents the ability to access, understand, appraise, communicate, and apply health information in ways that support appropriate health decisions. Health outcomes encompass perceived health status, health behavior, disease management, preventive practices, treatment adherence, and overall health related well being. The study is theoretically grounded in the Health Literacy Skills Framework, the Technology Acceptance Model, and the Information Seeking Process perspective. A quantitative cross sectional research design is proposed using a structured questionnaire administered to adult internet users and health information seekers. A five point Likert scale can be used to measure the constructs. Partial Least Squares Structural Equation Modeling through Smart PLS is recommended for evaluating the measurement and structural models and testing the mediation effect. The illustrative findings indicate that online health information seeking significantly improves health literacy, while health literacy significantly improves health outcomes. Online health information seeking also demonstrates a significant positive direct relationship with health outcomes. Mediation analysis indicates that health literacy significantly mediates the relationship between online health information seeking and health outcomes. The findings suggest that merely accessing large quantities of online health information may not be sufficient to improve health. Individuals must possess the skills necessary to distinguish credible information from inaccurate, misleading, or commercially motivated content. The study contributes to digital health research by identifying health literacy as a key mechanism connecting online information behavior with health outcomes. Practical implications include strengthening digital health literacy programs, improving the accessibility and readability of online health resources, promoting reliable health information sources, and helping individuals develop critical evaluation skills. The study concludes that online health information seeking can contribute positively to health when individuals possess adequate health literacy to interpret and apply the information effectively.
