This study develops and tests a model of online trust of a health care website. The model showed a statistically strong fit to the data (N=176). Trust was significantly explained by perceptions of credibility, ease of use, and risk. Perceived ease of use was a direct predictor of trust and an indirect predictor through credibility. Credibility was both a direct predictor of trust and an indirect predictor through risk.
