Online Trust and Health Information Websites

Health care websites are important to people managing their health. But the quality of the information on health care websites varies, so it's hard for users to decide whether to trust their information. This study develops and tests a model of the factors influencing users' initial trust of a health care website. The factors are perceived credibility, risk, and ease of use. A survey instrument was developed to test the model with 176 participants who interacted with a health care website. It had strong statistical reliability and validity, and the model showed a statistically strong fit to the data. Users' website trust was significantly explained by users' perceptions of website credibility, ease of use, and risk. Ease of use directly predicted trust, and affected trust indirectly through credibility. Credibility was a direct predictor of trust and an indirect predictor of trust through risk. Variance explained by the model was high, 0.73.
