The internet has created new possibilities for individuals to assume a more pronounced role in their own healthcare. This paper reports results from a study that examined the perceptions of older people of usability and trust in Internet health information. Information was also gathered on their ability to search for health information. Participants included 64 adults aged 60-82 years who were asked to answer health-related queries using websites that varied in usability. They were also asked to provide ratings of usability and of their trust in Internet health information. The results indicated that performance was lower for the "low usability" websites. Participants also rated these websites as having poorer layout, being harder to navigate, less useful and less understandable. The majority of the sample indicated that they would use the internet to find health information. These findings underscore the importance of considering usability issues when designing e-health applications.
