Technology offers innovative and promising methods of delivering health messages to provide knowledge and potentially facilitate improved health behaviors. Theory was foundational to the development of a new intervention using a tailored Web site and a handheld computer. A performance usability study was conducted to determine if women could use this newly developed intervention delivered via a Web site and pocket computer accurately and in a timely manner in real-world settings. A convenience sample of 15 women between 35 and 55 years of age were observed as they used "Complete a Task" and "Talk Aloud" performance usability methods. Results identified several problems affecting the ability of participants to use the Web site and handheld computer.
