The Internet has revolutionized health care delivery. With the increasing number of online users and the advancement of eHealth technologies, many health care studies have been conducted online. However, online research is still a relatively new field, and many methodological issues still need to be investigated. Over the years, the authors have conducted studies on various aspects of online health intervention research, including development and usability testing of online health interventions, Web surveys, and an online randomized controlled trial employing older adult online users. The purpose of this article was to describe lessons learned from conducting an online randomized controlled trial designed to improve older adults' health behaviors focusing on methodological issues and strategies to overcome them.
